Design protocols for Your work.

Building a Cafeteria Display in less than an hour

Hardware prerequisities: Raspberry 3B (3B+ if You want Your box to be supplied by Power-over-Ethernet), an >4GB SD CARD, HDMI cable, HDMI screen.

On Your linux host, do 

wget https://downloads.raspberrypi.org/raspbian_latest

Don't forget to unzip the file

unzip raspbian_latest

You should get a file with a name such as 2018-06-27-raspbian-stretch.img as an output. This filename Thou shalt use as a value of the if parameter of the dd command below.

Stick the new SD card into the host machine, find out its block device name (it will most probably appear as something like mmcblk0 at the bottom of the dmesg command), You will used this block device name, prefixed with /dev/, as a an of parameter of the command which allows You to copy the OS image to Your SD card ::

dd bs=4M if=raspbian_latest of=/dev/mmcblk0 conv=fsync

The copy will take few minutes, so go make Yourself a tea, sing a mantra or simply reflect about what You are doing just now, and what will be done in an hour or two.

When all is finished without a trouble (it should) You can check whether all partitions have been successfully created by ejecting and reinserting the SD-card adapter from Your host machine. Two partitions should automount, and having them already mounted, You can start configuring system even before actually starting PI.

You can, for example, prepare Your PI for its service as a component in a vertically (portrait, not landscape) oriented kiosk display, by adding the line

display_rotate = 3

then eject the SD card from the host system, put it into PI, plug the PI to the powersupply, connect keyboard, mice, HDMI screen, go through the main config (do not forget to set up at least reasonably solid password which You will not forget during the night !).

Launch terminal and install the ultra-fast openbox browser by executing


sudo aptitude install openbox obconf obmenu


and then make a openbox config file with  

mkdir -p ~/.config/openbox && cp /etc/xdg/openbox/* ~/.config/openbox


Then edit the autostart to openthe browser at boot
 

nano ~/.config/openbox/autostart


remove all the code and past this in: 

# Autostart script

#will sleep to make sure everything else loads

sleep 5s && midori  --inactivity-reset=120 -e Fullscreen --app=https://LINK-TO-YOUR-APP


that will make it run with fewer options auto resetting after 2 minutes inactivity.

Building a Pi Narrator

Hardware prerequisities:

Raspberry 3B, an >=16GB SD CARD, seeded respeaker 4-mic array HAT, voltcraft 2xUSB 5V-output 8000mA solar battery, USB2microUSB cable, speaker or headphones

host machine ideally running Linux

Setting up Your headless PI and Respeaker drivers

On Your linux host, do 

wget https://downloads.raspberrypi.org/raspbian_lite_latest

To download the "minimalist" variant of the Raspbian OS. Don't forget to unzip the file

unzip raspbian_lite_latest

You should get a file with a name such as YYYY-MM-DD-raspbian-stretch-lite.img as an output.

This filename Thou shalt use as a value of the if parameter of the dd command below.

Stick the new SD card into the host machine, find out its block device name (it will most probably appear as something like mmcblk0 at the bottom of the dmesg command), You will used this block device name, prefixed with /dev/, as a an of parameter of the command which allows You to copy the OS image to Your SD card ::

dd bs=4M if=YYYY-MM-DD-raspbian-stretch.img of=/dev/mmcblk0 conv=fsync

The copy will take few minutes, so go make Yourself a tea, sing a mantra or simply reflect about what You are doing just now, and what will be done in an hour or two.

When all is finished without a trouble (it should) You can check whether all partitions have been successfully created by ejecting and reinserting the SD-card adapter from Your host machine. Two partitions should automount, and having them already mounted, You can start configuring system even before actually starting PI.

Let's say that after automount, the rootfs of PIs SD card is mounted at /media/YourBaseStationUserNameHere/rootfs

Then You can start making Your Narrator to be ultra-autarch and low consumption by disabling the HDMI and ACT LEDs by adding these lines 

# Disable HDMI

/usr/bin/tvservice -o

# Disable ACT LEDs
sudo sh -c 'echo none > /sys/class/leds/led0/trigger'

sudo sh -c 'echo none > /sys/class/leds/led1/trigger'

sudo sh -c 'echo 0 > /sys/class/leds/led0/brightness'

sudo sh -c 'echo 0 > /sys/class/leds/led1/brightness'

to the end of PI's /etc/rc.local file (e.g. You can do it in VIM of Your host machine by running vim /media/YourBaseStationUserNameHere/rootfs/etc/rc.local), just above the exit 0 line.

#Later, when all is well setup, You could be even more radical and want to disable both Ethernet adapter as well as USB drivers, You can put
#echo 0x0 > /sys/devices/platform/soc/3f980000.usb/buspower
#into PI's rc.local

Even more importantly, You can turn off WIFI on a very basic level by running the command
echo "dtoverlay=pi3-disable-wifi" >>  /media/YourBaseStationUserNameHere/boot/config.txt

Enable the SSH by creating a file "ssh" on PI's boot partition

touch /media/YourBaseStationUserNameHere/boot/ssh

It is better to do this things directly from the base station because if ever You would like to do it on a running PI, You would have to remount the boot partition in a readwrite mount which is a minor hassle.

Ok, that's it, unmount the SD card from the base station and put it into the PI.

Start it by connecting the Powerbank with the PI with microUSB cable, locate PI's IP address on Your network

sudo nmap -sP 194.95.XXX.0/24 | awk '/^Nmap/{ip=$NF}/B8:27:EB/{print ip}'

You obtain the IP address to which You connect through SSH

ssh pi@IP-ADDRESS-YOU-OBTAINED-IN-PREVIOUS-STEP

default password should be raspberry. Change it immediately by running (already on Your PI, i.e. connected through SSH):

passwd

And now, let the fun begin.


apt install git
git clone https://github.com/respeaker/seeed-voicecard
cd seeed-voicecard
sudo ./install.sh 
sudo reboot

#test recording on ReSpeaker 4-mic
#It will capture sound on AC108 and save as helloworld.wav
arecord -Dac108 -f S32_LE -r 16000 -c 4 helloworld.wav
#plug Your headphones in PI's audio out and test it
aplay helloworld.wav

Not bad, hm ?

Digital Education @ UdK

Three topics of theoretical focus :
  1. Definition of Digital Education ("education-of" or "education-with" ?)
  2. Evaluation criteria for e-didactic tools, media and methods
  3. Parent participation in digital education

Two topics of PRAXIS :
  1. Evaluation and extension of "Computer Science Unplugged" curricula
  2. fibel.digital

Fibel :: Architectural primitives

Hardware is Raspberry Pi, OS is Raspbian which after booting automatically logs in the user fibel whose .bashrc specifies to launch xinit whose .xinitrec specifies to run chromium
Frontend is running in chromium which loads index.html which loads all the rest.

Interaction between backend services / sensors and frontend takes place by means of websockets. Every backend service pipes it outputs into pipes located in /dev/fibel, these pipes are created by bunch of gwsocket-daemons launched at startup, config file for service2port associations is in /etc/fibel/sockets.

All necessary frontend code for dealing with sockets is in js/sockets.js

Hacks and Tricks

Some useful know-how for creation of Your own digital Primer.

raspi(usb)-raspi zero+inkyPhat hack

I just realized that a following hack could be worth trying:

1) we have the main PI with all pins already taken but with an available USB port

2) we connect the cheapest 5$ no-WIFI variant of RasPI Zero to the USB of the "main" PI, and we put the inkyPhat on this pi zero

3) wittyPi starts the main PI

4) power starts to flow to main PI's usb port, hence the small PI starts

5) the main PI can communicate with the zero in a sort of ethernet-emulated through USB, c.f. https://www.thepolyglotdeveloper.com/2016/06/connect-raspberry-pi-zero-usb-cable-ssh ... for example, an image to-be-displayed can be sent from the main PI to the zero

6) once the image is transfered and displayed on the inkyPhat, pi zero can communicate to the main PI that the job was done and halt

7) additionally, the main PI can shut down the USB port through which the zero was powered ... c.f. https://www.raspberrypi.org/forums/viewtopic.php?t=93463 , if  that hub-ctrl.c will work than it is a hammer

8) when a new image is supposed to be displayed on the inkyPHAT, power flow to the USB port can be reactivated and steps 4-7 can be repeated

The idea is to counterbalance the deficit of GPIO pins on a PI with communication with "peripheral" zeros, which have a new full set of GPIOs, are small and cost 5$ a piece...

Raspberry Pi Kiosk Tutorial

Raspberry Pi Kiosk Tutorial

(mirror of https://bartsimons.me/raspberry-pi-kiosk-tutorial/)

The Raspberry Pi has proven itself to be a great computing device while keeping cost as low as possible. For less than $40 you are getting a great little device…

The Raspberry Pi has proven itself to be a great computing device while keeping cost as low as possible. For less than $40 you are getting a great little device with its 64-bit ARM processor. This made me think, would it be a good idea to turn the Raspberry Pi 3 into a kiosk?

The software that you'll need

A list is not even needed, because you only need three things: Raspbian Jessie Lite installed as the OS, the X11 display stack installed and the Chromium webbrowser installed on the Pi.

Why Chromium

Chromium is the open source variant of the popular Google Chrome browser. It has great potential for this project because of the --kiosk flag. With this option you can create a full-screen browser window inside your empty X11 session.

Installing the X11 display stack

You can install the X11 display stack on your Raspberry Pi with the following command:

sudo apt install xserver-xorg xinit

This will install the X11 server on your Pi together with the X11 server initialisation program. You also have to run this command:

sudo dpkg-reconfigure x11-common

To select who's authorized to start the X11 server. Make sure it is set like this:

x11-common package reconfiguration

Installing Chromium

Just run sudo apt install chromium-browser to install Chromium on your Pi. It's literally that simple.

Writing the .xinitrc script

When you execute the xinit command on your Pi, you will see a terminal window instead of Chromium. To fix this, you'll need to write a file in your home directory called ~/.xinitrc. This file contains everything that gets run when the X11 server starts up. So, edit this file with nano (or any other text editor) and make sure it looks like this:

.xinitrc file with Chromium

Save it, and try running Chromium by invoking the xinit command on your Pi.

But... my window is not fullscreen!

It could be that your Pi shows black borders around the screen, which has to do something with overscan. Open your /boot/config.txt file (with sudo) and add disable_overscan=1 to this file like this:

Disable Overscan

Reboot your Pi and the problem should magically disappear! (at least, that's what happened to me...)

Starting X11 at boot

Raspbian comes with a built-in tool to configure your Pi: raspi-config. Run this command on your Pi and you will be greeted with a command-line dialog window. Go to option 3 and press enter:

raspi-config main menu option 3

And then go for option 2:

raspi-config boot options option 2

Press enter, go to finish and when the program asks for a reboot choose yes.

Once you have rebooted your Pi, you'll have to do one more thing to finish this project: finally starting X11 at boot! My method might be more sophisticated than needed, but hey: it worked for me. Edit the ~/.bashrc file in your favourite text editor and add the following to the bottom of the file:

if [ -z "$SSH_CLIENT" ] || [ -z "$SSH_TTY" ]; then
    xinit -- -nocursor
fi

save the file and reboot your Pi. Enjoy your beautiful self-made Raspberry Pi Kiosk!

Load webpage from an URL specified in a file

A Raspberry Pi with the default partition layout contains two partitions: the OS partition, and the BOOT partition which is formatted in FAT32 and gets automatically mounted at boot. For example: create a new file in /boot/ called website.txt and put your desired URL in it. Finally to make it work you simply replace the URL in your ~/.xinitrc file with $(cat /boot/website.txt) and it should work! The thing is that you can actually see and modify contents of this file in Windows, since the BOOT partition is partitioned as FAT.

Session 2 - Constraints

Of constraints, their usefulness and influence they exerce on design and designers of the Primer artefact

Homework

Think about all possible and impossible constraints (and obstacles) which could (and many of them also will ;) during the creative process.

Try to categorize these constraints into 3-5 main categories.

Motto

Constraints are designer's (strongest) allies.

Categories of constraints

...to which an artefact like digital Primer is to be a subject.

Alan Kay - A personal computer for children of all ages

The KiddiComp concept, envisioned by Alan Kay in 1968 while a PhD candidate,and later developed and described as the Dynabook in his 1972 proposal "A personal computer for children of all ages", outlines the requirements for a conceptual portable educational device that would offer similar functionality to that now supplied via a laptop computer or (in some of its other incarnations) a tablet or slate computerwith the exception of the requirement for any Dynabook device offering near eternal battery life. Adults could also use a Dynabook, but the target audience was children.


Part of the motivation and funding for the Dynabook project came from the need for portable military maintenance, repair, and operations documentation. Eliminating the need to move large amounts of difficult-to-access paper in a dynamic military theatre provided significant US Department of Defense funding.


Though the hardware required to create a Dynabook is here today, Alan Kay still thinks the Dynabook hasn't been invented yet, because key software and educational curricula are missing.

Session 2 - Art & Artefact

Before doing the theory let's test our paper airplanes!

Art

  1. (uncountable) The conscious production or arrangement of sounds, colours, forms, movements, or other elements in a manner that affects the senses and emotions, usually specifically the production of the beautiful in a graphic or plastic medium. 
    There is a debate as to whether graffiti is art or vandalism.
  2. (countable) Skillful creative activity, usually with an aesthetic focus.
    She's mastered the art of programming.
  3. (uncountable) The study and the product of these processes.
    He's at university to study art.

Artifact

artifact (plural artifacts)



  1. An object made or shaped by human hand.

  2. (archaeology) An object, such as a tool, weapon or ornament, of archaeological or historical interest, especially such an object found at an archaeological excavation. 

    The dig produced many Roman artifacts.

  3. Something viewed as a product of human conception or agency rather than an inherent element. 

  4. A structure or finding in an experiment or investigation that is not a true feature of the object under observation, but is a result of external action, the test arrangement, or an experimental error.

    The spot on his lung turned out to be an artifact of the X-ray process.


  5. (biology) A structure or appearance in protoplasm due to death, method of preparation of specimens, or the use of reagents, and not present during life.

  6. An object made or shaped by some agent or intelligence, not necessarily of direct human origin.

  7. (computing) A perceptible distortion that appears in a digital image, audio or video file as a result of applying a lossy compression algorithm.

Over the years we’ve seen the Raspberry Pi crammed into almost any piece of hardware you can think of. Frankly, seeing what kind of unusual consumer gadget you can shoehorn a Pi into has become something of a meme in our circles. But the thing we see considerably less of are custom designed practical enclosures which actually play to the Pi’s strengths. Which is a shame, because as the MutantC created by [rahmanshaber] shows, there’s some incredible untapped potential there.

The MutantC features a QWERTY keyboard and sliding display, and seems more than a little inspired by early smartphone designs. You know, how they were before Apple came in and managed to convince every other manufacturer that there was no future for mobile devices with hardware keyboards. Unfortunately, hacking sessions will need to remain tethered as there’s currently no battery in the device. Though this is something [rahmanshaber] says he’s actively working on.

The custom PCB in the MutantC will work with either the Pi Zero or the full size variant, but [rahmanshaber] warns that the latest and greatest Pi 4 isn’t supported due to concerns about overheating. Beyond the Pi the parts list is pretty short, and mainly boils down to the 3D printed enclosure and the components required for the QWERTY board:  43 tactile switches and a SparkFun Pro Micro. Everything is open source, so you can have your own boards run off, print your case, and you’ll be well on the way to reliving those two-way pager glory days.

We’re excited to see where such a well documented open source project like MutantC goes from here. While the lack of an internal battery might be a show stopper for some applications, we think the overall form factor here is fantastic. Combined with the knowledge [Brian Benchoff] collected in his quest to perfect the small-scale keyboard, you’d have something very close to the mythical mobile Linux device that hackers have been dreaming of.

Raspberry pi 

Der Raspberry Pi (engl. Aussprache: ˈɹɑːzbɹi 'paɪ) ist ein Einplatinencomputer, der von der britischen Raspberry Pi Foundationentwickelt wurde. Der Rechner enthält ein Ein-Chip-System von Broadcom mit einem ARM-Mikroprozessor, die Grundfläche der Platine entspricht etwa den Abmessungen einer Kreditkarte. Der Raspberry Pi kam Anfang 2012 auf den Markt; sein großer Markterfolg wird teils als Revival des bis dahin weitgehend bedeutungslos gewordenen Heimcomputers zum Programmieren und Experimentieren angesehen.[1] Der im Vergleich zu üblichen Personal Computern sehr einfach aufgebaute Rechner wurde von der Stiftung mit dem Ziel entwickelt, jungen Menschen den Erwerb von Programmier- und Hardware­kenntnissen zu erleichtern. Entsprechend niedrig wurde der Verkaufspreis angesetzt, der je nach Modell etwa 5 bis 35 USD beträgt.


Bis Ende 2017 wurden mehr als 17 Millionen Geräte verkauft.[2] Die Entwicklung des Raspberry Pi wurde mit mehreren Auszeichnungen bzw. Ehrungen bedacht. Es existiert ein großes Zubehör- und Softwareangebot für zahlreiche Anwendungsbereiche. Verbreitet ist beispielsweise die Verwendung als Mediacenter, da der Rechner Videodaten mit voller HD-Auflösung (1080p) dekodieren und über die HDMI-Schnittstelle ausgeben kann. Als Betriebssystem kommen vor allem angepasste Linux-Distributionen mit grafischer Benutzeroberfläche zum Einsatz; für das neueste Modell existiert auch Windows 10 in einer speziellen Internet-of-Things-Version ohne grafische Benutzeroberfläche. Der Startvorgang erfolgt gewöhnlich von einer wechselbaren SD-Speicherkarte als internes Boot-Medium. Bei der neueren Generation mit dem BCM2837 ist der Start auch von einem USB-Massenspeicher[3] oder Netzwerk[4]möglich. Eine native Schnittstelle für Festplattenlaufwerke ist nicht vorhanden, zusätzlicher Massenspeicher kann per USB-Schnittstelle angeschlossen werden, beispielsweise externe Festplatten bzw. SSDs oder USB-Speichersticks.

(with Chris Schmidts, Akif Sari)
Head-shaped tridecahedral (13-plane) wooden shell crafted by Chris Schmidts and filled with Raspberry pi 3A+, Seeed Respeaker (4mic circular array, ac108 converter; APA102 12-LED RGB pixel ring) enriched with UltraSonic Ranger System sending UDP packets to "active wall" installation by architecture student Akif Sari.

6-inch e-ink displays page 4. of McGuffey's Ecclectic Primer, a well-known Fibel of Victorian Era. Display is currently powered off and as such has zero carbon dioxide trace (hallo Gretha!) while still teaching Alphabet. To see more interactive e-ink setup please check the artefact CardboardFibel0.

Carboard Primer

(with Astrid Kraniger)
First functional cardboard-embedded artefact combining touchless gesture-based recognition (Seeed Grove Gesture Recognition Sensor PAJ7620U2）with an e-ink controlled by IT8591 board and some ANSI C coded  for the purpose of diagnostics of difficulties in acquisition of learning and writing (Leserechtschreibschwierigkeiten - LRS).

Diagnostics focuses on so-called "Rapid Automatized Naming" which is considered to be one among the most important LRS-predictors.

Visual content ("animal pictures") scanned from reedition of Lumen Picturae et Delineationis (Amsterdam, 1660, BE310).

Instead of a signature, this artefact contains a four-leaf clover (harvested in July) attached by duct-tape above the e-ink screen. Bottom of the cardboard shell is photovoltaic, making it possible to transform PappeFibel 0 or one of its derivatives into an energy-autarch ("eutark"; Hromada, 2019, AE49) digital education artefact.

TASK: Identify mismatch between visual and textual modality. 

INSTRUCTION OF USE: You interact with the device by moving Your hand in front of the Gesture Recognition Sensor (to the right from e-ink screen). Movement along vertical axis (up/down) maps to boolean (true/false, JA/NEIN) answers. Movement along horizontal axis (left/right) is used to browse the content. Rotation is used to switch between "learning" and "testing" mode.

CAVEAT: When changing modes of operation, new data has to be loaded into the buffer of the e-ink controller. This takes few seconds. Be patient. Breathe.

Touchless Ukulele

(with Anna Petzer)
This upcycled, portable, cable-less digital artefact combines touchless gesture-based recognition (Skywriter sensor）with a Raspberry pi 3a+ and integrated bluetooth loudspeaker.

TASK: Play with speed (time), position (space) and quality (suspense) of your hand movements. 

INSTRUCTION OF USE: You interact with the device by moving Your hand in front of the Skywriter sensor (above the sound hole of the instrument). Play the string to observe how the string vibration deforms the field measured by Skywriter. 

sonic

(with Nikoloz Kapanadze)
sonic is an experiment on the topic of screenless computers. what would our smart devices look like, and act like if they were not bound by the rectangular standard of the screen. sonic is a pair of headtracking headphones powered by a Raspberry Pi. the headtracking information is used to control a supercollider program that performs binaural processing. in  other worrds the spatial positions of sound sources are  decoupled from the listeners frame of reference. so to say the sounds stay in place as the user changes the orientation of their head. its like VR but for your ears not your eyes.

the device can also record stereo audio using the two microphones mounted on the two earcups. having microphones so close to where one's ears would be gives the sound a lot of presence.  the componnts are mounted on a pair of headphones that i've had for around five years now and the whole assembly is modular, meaning that faulty components can be easily swapped out.

sonic uses twin i2s mems microphones( SPH0645) for audio recording and a accelerometer+gyroscope+magnetometer(LSM9DS1) ic for head-tracking.

In a Praise Of Void

The stable "wall" is the very basis of land creatures and thus by "having responsive space rather than the linear presentation of the wall," the body is suddenly made aware of the situation it is in.

With the current housing crises and the reduction of the living space per person, the effect of the occupancy and void becomes more valuable day by day. But this concept, void, which can only be defined by its contrast: fullness, and which can change the perception of everyday spaces we are accustomed like a room, is not easily readable. This situation removes the concept from our daily practices and traps it in the dusty pages of abstract architectural books.

The project based on an example ordinary wall of living space offers a responsive space that will bring up a concept of void on the agenda in order to challenge perceptions of living space and physical context.

This exploration simulates an extreme architecture of responsive variable structure by suggesting a technological infrastructure with hypothetical material.

The narrative analyzes the benefits and limitations of these projects but avoids explaining the necessity and result of living in such a space. It remains speculative, is leaving the questions open for the next phases.

Principles of Operation

0) We are a team aspiring to attain the Goal. The Goal is to be specified at the 1st meeting.
1) We work in two-week cycles. Each cycle is divided into two week-long subcycles.
2) Each cycle is initiated by a meeting ("the Gathering") where all team members participate in person.
3) The first subcycle, the first week, is the week when common team work takes place. That means that asides the Gathering, at least two additional 5-hour sessions of common hacking and exchange take place.
4)  The second subcycle, the second week, is the consolidation week wherein everybody does his work alone. 
5)  During the second week one aims to solve the tasks defined at the end of the first week.
6)  The task is defined as a "challenge or problem where a solution is imaginable and/or reachable" within a week time span


  • every team member gives (him|her)self one task which can be solved within a one week span

  • every team member gives one task to the project integrator

  • project integrator attributes one task to scientific counselor


In a situation where a team is composed of 1 project integrator (PI : Daniel), 1 scientific counselor (SC: Georgy), 1 engineer (ENG: Nik) and 1 data-collector (DC: Astrid), tasks are therefore distributed as follows:


  • PI: 4 tasks 

  • SC: 2 tasks

  • ENG & DC: 1 task


7) At the beginning of the Gathering, everybody presents not only outcome of his efforts to solve the tasks but, more importantly, discusses problems & drawbacks which occured. Also, the failure to accomplish the task does not problem as far as one learned something in the process (e.g. that the imaginable solution is not reachable under certain constraints).

Knot related to European Research Council Starting Grant proposal.

2000 char description

It is generally accepted that formation of certain habits in an early age can have a significant impact on development of cognition, psychology and physiology of human children. Certain among such habits may lead to increase in one's personal integrity and social well-being in adulthood, other may decrease it. We call the former ones "benign" habits.


Within our project, we define the basic literacy (BL) - e.g. ability to read a book and write with a pen - as a bundle of such "benign" habits. Basic literacy is not an innate faculty, but rather a culturally determined skill whose acquisition can be fostered or inhibited by child's exposure to appropriate resp. inappropriate social, pedagogic and instrumental context.


Growing amount of evidence indicates that structural and functional design of dominating digital media (DM) - most notably smartphones- leads to overstimulation of dopaminoergic system which can influence formation of associative pathways and induce emergence of strong sensorimotric habits.


Given this, it may be hypothesized that acquisition or reinforcement of smartphone-related habits interferes with acquisition of habits relative to acquisition of basic literacy.


Surprisingly, in spite of a big market offer of different devices and "apps" pretending to promote acquisition of BL, there is currently little empiric research available, addressing this concrete question:




  • Does usage of DM by pre-school children and elementary school pupils positively or negatively interfere with their acquisition of BL ?




A primary objective of our ERC project is an empiric one: to answer the above question by a multi-factor cohort study. Secondary objective of our project is to explain the empiric results in terms of "embodied cognition" paradigm. Lastly, the constructive objective of the project is to develop cognitively sound methods and instruments whose application could minimize the negative impact of DM on acquisition of BL and maximize the positive one.

State of the Art


purpose – evaluation of sensorimotoric habits in children..........


there are two strategies one could take to tackle this problem:


  • Software Approach

  • Hardware Approach


Software Approach 


Choosing this strategy entails developing software that would run on the devices these kids are interacting with:

the advantages to this approach is that there is no need to manufacture a new gadget and it facilitates large scale data collection remotely.

However the software solution would have to support an extremely large codebase – across multiple form factors (smartphones, tablets, [PC]) as well as multiple operating systems (android, ios, [linux, macos, windows]). 

In addition to that such a software would require deeper integration with these device on the operating system level – (loging keystrokes, touch info, gather data about background processes), such logging tasks are very platform specific and would differ significantly not only from os to os but also across versions of the os. This is especially true for android which accounts for the vast portion of touch based devices and exhibits a great amount of  version fragmentation. It would take a lot of effort to deploy such a system across these devices in a democratic fashion ex: 


children from with a poorer family background would be more likely to have an outdated devices and would run a higher risk of being excluded – as it would only be logical to prioritize newer version of  operating systems during the development stages


In addition to that to able to deploy such software on multiple devices efficiently it would have to go through the proper distribution channels for said operating systems (play store, app store). This would impose additional restrictions due to said os-s permission management systems – the software has to be able to log information and interactions that occur outside of its “jurisdiction”

all of this is extremely inconvenient in a setting of field work, even if the software were to satisfy all of the above criteria – for an “evaluation event” to take place lots of effort and preparation – software has to be installed across

in addition to that since all of these mainstream devices are built with an “always-online” philosophy it would require extra care (since we're dealing with underage data) when designing said software to make encryption and privacy watertight to avoid breaches of information. 

In general our philosophy is to avoid being reliant on web services – as much data processing and collection should occur locally. Going with the software approach gets too many external factors and third parties involved which we want to avoid.


Hardware Approach


sensorimotoric habits that we are interested in evaluating require physical motion so external tracking devices that would be good at detecting and analyzing said motion would be a viable solution. Such a tracking device would be able to serve as an input method further down the line considering it is able to identify interactions reliably. This is a nice feedback loop. 

There are two sub approaches in the hardware category:


  • Device Mounted Tracker (DMT)

  • Wearable Tracker (WT)


If it is able to externally correctly identify touchscreen interactions – 

it can work as a standing for the touchscreen.


A device mounted tracker would be able to detect taps and swipes from the child’s interaction with the device using an accelerometer that listens to the vibrations in the body of the smartphone as a it is being tapped on. such a device would have to be less compact than it’s wearable counterepart. using the back of an average smartphone as reference. in theory it would allow for longer service time between recharges, potentially higher data transfer rates (the benefits of this are questionable as the data we’re collecting is of negligible size), but most importantly it could be equipped with a faster processor that would be able to perform more complex statistical analysis tasks locally, in  the field instead of after data transfer to the evaluator’s computer. increased processing power and battery capacity would also allow for optical detection methods potentially allowing us to collect more information on what the smartphone is being used for. (a bit out of scope of this project) such a device would also allow for more sensors to be added to it down the line making it somewhat modular as opposed to making modifications to a wearable which would likely require redesign of the entire device if new functionality were required. 


the material requirements are also lower - a 3d printed case would suffice. a device mounted tracker would have to be slim and ergonomic, but it wouldn’t have to be comfortable. it wouldn't have to be in prolonged contact with skin. whereas a wearable might need to use softer materials such as silicones and rubbers which have a more complicated manufacturing process, might have to be outsourced and might be less durable.


a wearable device on the other hand would provide much higher resolution motion data. even a 3DoF accelerometer ic mounted in a ring would be able to detect all sorts of finger motion: taps, swipes and various other 3d gestures not just in binary form (“detected swipe up at 10:23:15”) but also the characteristics of these gestures (swipe speed, tap strength, swipe direction, distance from screen, etc.). such a device would also be able to measure eye-finger coordination more generically be evaluating fluidity of motion, gesture shape, etc. information collected from such  ring would also provide valuable insights when tracking the motion of someone writing using traditional media. 


a wearable device would also allow for collection of other biometric data such as heart rate, skin moisture and temperature. to asses agitation for instance. it would naturally be harder to fit multiple sensors inside a ring so a bracelet (decreases accelerometer precision for finger movement), multiple rings, or a ring and bracelet combination.


we are leaning the wearable way. since its motor habit evaluation being closest to the source of motion seems best.


there are several hardware projects that satisfy one or several of the above criteria


tap with us – wearable keyboard. 5 rings for each finger. can track individual accelerations of each finger, responds to taps on hard surfaces, wearable, 5 ring assembly is quite large, could be distracting


kai – gesture tracking bracelet for your palm, tracks individual finger motion(optical?), wearable, about the size of tap, could be distracting


motiv ring - biometric nfc ring, with accelerometers also (needs further research)

Using QtWebKit as the back-end, it offers fast and native support for various web standards: DOM handling, CSS selector, JSON, Canvas, and SVG.

The following simple script for PhantomJS loads Google homepage, waits a bit, and then captures it to an image.

var page = require('webpage').create();
page.open('http://www.google.com', function() {
    setTimeout(function() {
        page.render('google.png');
        phantom.exit();
    }, 200);
});

I2c Devices Have the Same Address

It seems we do not need I2C multiplexers at all. Paste from https://www.instructables.com/id/Raspberry-PI-Multiple-I2c-Devices/

An i2c bus can handle multiple devices, but they should have different i2c addresses. Some i2c devices have jumpers to set other i2c addresses, but many don't. In this case you may use a i2c multiplexer (hardware) to rotate the i2c SDA (Data) and SCL (Clock) or you can create an additional i2c bus or more.

I will create two aditional busses, nl bus 3 and 4

Open the cli and run

cd /boot

sudo nano config.txt

Add the following line of code, preferable in the section where spi and i2c is enabled.

dtoverlay=i2c-gpio,bus=4,i2c_gpio_delay_us=1,i2c_gpio_sda=23,i2c_gpio_scl=24

This line will create an aditional i2c bus (bus 4) on GPIO 23 as SDA and GPIO 24 as SCL (GPIO 23 and 24 is defaults)

Also add the following line to create i2c bus 3

dtoverlay=i2c-gpio,bus=3,i2c_gpio_delay_us=1,i2c_gpio_sda=17,i2c_gpio_scl=27

GPIO 17 will be the SDA and GPIO 27 will be the SCL for i2c bus 4.

Tipe control X to exit.

Note on the Bus Numbering and order:

Never use bus 0 and 2, it is use for other things in the board like eprom on hats etc

For the April 2019 raspbian release:

You should always start with the highest bus (Bus 4 in this case) in your config.txt and work through to the lowest bus (bus 3).

The lowest bus must always be bus 3

If you need 5 extra busses, the busses must bi in the order of 7,6, 5, 4, 3

This issue on bus order was not there when this Instructable was originally written. It seems like changes was made to the kernel.

Shut down your PI, switch it of. Connect your i2c devices to bus 4 (SDA to GPIO 23 and SCL to GPIO 24) and the other to i2c bus 3 (SDA to GPIO 17 and SCL to GPIO 27).

Switch on the pi.

Run:

sudo i2cdetect -l (Lower Case L)

You will now see that i2c bus 3 and 4 is also listed. Also run:

sudo i2cdetect -y 3

sudo i2cdetect -y 4

Now you can use your sensor in your programming language. Remember to specify the correct i2c busses.

Attach is an example for the popular BMP280 Temperature and Pressure sensor. No multiplexer can read 2 BMP280s this fast.

An example of 2 Sensirion SDP 810 sensors is also attach. Again working much faster than the multiplexer I used in the past




2nd grove gesture recognition plugged through re:speaker

#add an i2c-bus 3 into /boot/config.txt
dtoverlay=i2c-gpio,bus=3,i2c_gpio_delay_us=1,i2c_gpio_sda=13,i2c_gpio_scl=12
#attach the 2nd gesture sensor in respeaker's "GP12" grove port
#reboot and check whether You see the sensor attached to 3rd bus (i2cdetect -y 3)

ML on PI Zero

tf and keras installation:

pip3 install https://github.com/lhelontra/tensorflow-on-arm/releases/download/v1.8.0/tensorflow-1.8.0-cp35-none-linux_armv6l.whl
pip3 install keras
pip3 install pyaudio
 
Loading model on Pi Zero
model=load_model()  #is too slow!!!
 
faster way to load model from JSON:
 
json_file = open('model.json', 'r')
loaded_model_json = json_file.read()
json_file.close()
model = model_from_json(loaded_model_json)

model.load_weights("model.h5")
 
Saving model to JSON:
 
model_json = model.to_json()
with open("model.json", "w") as json_file:
    json_file.write(model_json)
model.save_weights('model.h5')

i2c problem

Raspberry Pi: reset external I2C devices (not only I2C)

Electronic, and specially computerized, devices likes to hang from time to time. There are many reasons: software bug, hardware error, voltage drop, interference, too long wire, random incident. I’ve learned this hard way during work on my Raspberry Pi based weather station. From time to time external DTH22 temperature/humidity sensor refused to work. Only solution was to cut power to DHT22 for a second (or less). It was kind of irritating to go the attic, unplug sensor and plug in again. Later on I had similar issues with HD44780 LCD display over I2C bus. Device was hanging and only solution was to cut power. So, I’ve found a solution: as a prevention cut power for a second every 30 minutes with a simple electronic device I’ve called “Power Cutter”.

Raspberry Pi power cutter

What is does? Not much. Long story short, it’s a 3.3V power regulator that when there is no input, it is just providing GND and 3.3V voltage. But when HIGH state is applied on input, it “disconnects” GND and shuts down all devices that are using this GND line. Not only powered via LM2950 3.3V (or LM7833 or any other) linear voltage stabilizer. All using this specific GND line.

LM2950 Raspberry Pi Power Cutter

In my application there is cron job executing simple python script every 30 minutes.

import RPi.GPIO as GPIO
import time
def main():
# GPIO.setwarnings(False)
GPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.OUT)
GPIO.output(18, GPIO.HIGH)
time.sleep(5);
GPIO.output(18, GPIO.LOW)
GPIO.cleanup()
if __name__ == "__main__":
main()
view rawcutter.py hosted with ❤ by GitHub

Simple and efficient. All external sensors are reseted every 30 minutes. Just in case. Since I stared using this device DHT22 sensor did not hanged even once. And that was the goal.

Miscellanous

We are going to plant some trees - of either organic , digital or epistemic nature - and observe their growth . We are going to dive into the history of culture to see what role trees and tree - like structures played in development of diverse arts . We are going to explore a certain similarity-of-forms - a certain " morphism "- between botanic entities known as " Bäume " and arborescent metaphors frequently used in informatics and computer science ( e.g. folder - subfolder - file structures, discussion forum " threads ", grammars , UNIX #root , direct acyclic graphs etc .). In order to avoid being too scholastic and hence potentially boring , we shall also ask a question " What is the essence of a Tree ?" and we will try to address this question by refering to both mythology and religion ( e.g. Yggdrasil , tree of knowledge , tree of life ), fantasy ( e.g. Tolkien's " Ents "), sci-fi ( Dan Simmons' " treeship "; Neal Stephenson's " Arbre ") and pre-factual non-fiction literature ( role of trees in Lovelock's vision of the upcoming Novacene ). Along the way , we are going to explore category structure of diverse social networks and digital communities like kyberia.sk or kastalia.medienhaus . The course will conclude with a short excursion into the realm of fractals , databases and A.I.s and " machine learning " wherein the " tree metaphor " also seems to bring some fruit ( e.g. " binary tree ", " decision trees ", " random forests " etc. ) And if times allows it , we'll start dealing with Wittgenstein 's Tractatus whose form seems to be ... a tree .

Tod.

 

Ein Mensch liegt schlaff und ausgestreckt am Boden.

Ein Knabe steht neben ihm mit einer umgekehrten und ausgelöschten Fackel.

So wie die Fackel ihren Schein verlohren hat, ist bei dem Menschen auch des Lebens Glanz verloschen.

Sein Auge sieht nicht mehr.

Sein Ohr vernimmt nicht mehr.

Er athmet nicht.

Sein Herz schlägt nicht mehr.

Die Schlafenden gleichen den Todten.

Auf den Tag folget die Nacht.

Auf das Wachen folget der Schlaf.

Auf die Arbeit folget die Ruhe.

Auf das Leben folget der Tod.

PPP IntCom

Re: IT8951

Dear Nik,

great that You started playing with the main hero of this semester ! On Friday I also played with BCM2835_SPI_CLOCK_DIVIDER parameter a little and it helped.

Tuning of BMP format helps as well, of course - please remind me we should discuss this tomorrow (also spent some manhours exploring the issue) - but the main culprit is IMHO the SPI transfer.

However, I think the ultimate hack would be to do something similiar to this https://github.com/waveshare/IT8951/pull/3 , i.e. tune the IT8951HostAreaPackedPixelWrite function

(but beware: if I use that naluhh:perf-opti code on the PiZero setup, it literally freezes the system

D.

P.S. good news: students of Kerstin Hille's drawing class created some beautiful content for us and more deeper collab between us and them (they are next door) seems quite probable

I've been hacking around epaper a little bit.

dug deeper into the library.

I've found that if images are encoded to proper format outside of the library (I've been using a cli tool called imageMagic)

I can pretty reliably display the image (uploading to epaper and displaying) in a bit more than 2sec (2020-2060 microsec)

Idk how it compares to previous speeds but at least it feel just as fast as our current transitions.

The waveshare lib seems to have some extra steps fro handling different types of bmp-s and actually converts them to conform to 8bpp spec. getting rid of all that seems to help. 

I also reliably doubled the spi clock speed. (setting it to the next available speed breaks communications)

will share on tuesday.

... Works like a charm.

 

The model I have is ED060SCG (this one one paper should have touch functionality though idk if it can be implemented with IT8951) - costs pretty much the same as what waveshare sells.

however if it's backwards compatible with variants from older kindles(ED060SC7(~18$) & ED060SCE(~23$, backlit)) it might be about 10$ cheaper 35%

Python for e-paper IT8951

I updated original PaperTTY lib so there are extra features.
it uses Pillow for images so any image format can be used (check Pillow documentation)
plus any Pillow features for drawing, animation, text etc (Pillow is pretty powerfull for image processing)

requirements for using python IT8951 lib:
enable SPI in raspi-config
install python libs: Pillow, RPi.GPIO, spidev
should work without sudo

library is at  Fibel / Code / e-paper-python3.7
put driver folder in your code folder
original PaperTTY lib is driver_it8951.py
mine version is it8951.py

here is example of using it:


from PIL import Image, ImageDraw
import drivers.drivers_base as drivers_base
# import my version of lib with extra features
import drivers.it8951 as driver_it8951

# if you wanna use original PaperTTY lib change the line to import drivers.driver_it8951 as driver_it8951

# init communication with IT8951
driver=driver_it8951.IT8951()
driver.init(partial=True)

# get address of 0 page (first page of framebuffer)
img_addr=driver.img_addr

# get values for black and white
black = driver.black
white = driver.white

# get size of your screen
width = driver.width
height = driver.height

# this function convert page number to address of framebuffer
def pageList(img_addr,page):
    return img_addr+page*(2*driver.width*driver.height+1)

# load image with Pillow
filename = '' # please provide path to your file
image=Image.open(filename)
# and convert it to BW format
image=image.convert('1')

   
pageNumber = 0 # define page of frambuffer where to load the image
driver.load_image(0,0,image,img_addr=pageList(img_addr,pageNumber))

# display image from specified page of framebuffer (pageNumber)
driver.display_buffer_area(0,0,width,height,1,pageList(img_addr,pageNumber))

# you can use any function of Pillow lib to draw and print the text
# here is example of drawing simple line

image = Image.new('1',(image.width,image.height),white)
draw = ImageDraw.Draw(image)
draw.line((0,0,width,height),fill=black)

# load it to page 1 so we can keep previous loaded image

Plug arduino in USB port.

maybe: pip install pyserial

should work from Fibel_V1 root dir

in tests 5x5 seems the smallest chunk you can pass display_buffer_area

Protocoll Assembly Fibel 16.06.20

Notes on the Assembly of the Fibel: The waveshare wm8960 "can operate at up to 5.5V, providing 1W per channel into 8 ohm loads". Varios speaker provide diffrent resistance, but slightly under or over the value seems to work fine aswell. The connector of the epaper hat seem just to work with the down side marked connector

WARNING :: Do not mess too much with e-paper replugging in the IT8951 controller when controller is under power. You may brick the controller->IT8951 circuitry badly.
