Unabriged version of the article "Integer-based nomenclature for the ecosystem of lexically repetitive expressions in complete works of William Shakespeare" now under Open Access

1606127686 / AE501123 ,

What do William Shakespeare's Falstaff, Prospero, Miranda, Online Encyclopedia of Integer Sequences, PERL-compatible regular expressions, Einstein Center Digital Future, #UdK, computational #rhetorics, #argument, #computation, morally restricted Genral Public License and a domain have in common ? Well, they are linked, in one way or another - to and by the paper "Integer-based nomenclature for the ecosystem of lexically repetitive expressions in complete works of William Shakespeare", one among the most strange yet most important papers I've ever written.

Thanks to UdK's Opus repository, the paper - also containing some goto-statement-containing source code ;) - is now officially available under Open Access. Having a DOI of their own, Shakespeare and Entangled numbers are now ready to (serve|amuse) You. Enjoy! :: a beautifully human success

A little cooking recipe for organisation of a first fully digital version of UdK's Zukunftstag: 10% mail & 5% Webex to ignite the spark. Then 70% of Medienhaus/ and 15% of BigBlueButton.

And a wonderful, wonderful project event organization group !

Result: More than 130 simulatenous users in 4 parallel conference tracks. An on-line event running non-stop for more than 12 hours. All this consuming less than 50% resources of a couple of local, non-corporate, university-hosted BigBlueButton servers.

Goodbye Zoom, goodbye Slack!

Article "Digital education: ”education-with” / ”education-about” distinction and the teleological definition" now under Open Access

1601977742 / AE501006 ,

Despite being an object of multi-billion public policies and private sector initiatives, the term ”digital education” seems to lack a clear, unambigous, lexicon-ready definition. A closer analysis reveals that in common parlance, the term is used to denote phenomena related to overlapping but distinct topics like ”technology”, ”media” or ”informatics”. Such polysemy implies an overall lack of clarity which a public debate about education policies should rather avoid. For this reason, we propose to start sorting things out by defining the term ”digital education” in terms of dichotomy of two subordinated concepts, which we label as ”education-about-digital” and ”education-with-digital”. Postulation of this dichotomy combined with analysis of "school's mission" as defined in the legal codices of Land Berlin naturally leads to ”teleological definition” which delimits the concept of digital education in terms of its ideal human result.

Digital Primer Code is now on Github

1589290105 / AE500512

At the URL You will find some necessary software bricks which will allow You to create Your own variant of a digital Primer (DP). DP is a new kind of medium whose raison d'etre is to educate. Its ideal hardware embodiment looks like a book and hadigital primers multiple properties of a book. Instead of using screens, device uses e-ink displays (mostly using IT8951 controller) to present visual or textual content. Strong emphasis is to be put on speech technologies (automatic speech recognition and speech synthesis) and touchless human-machine interaction. Recommended platform: Raspberry Pi Zero running Raspbian OS.

New team Member: Paul Seidler

Prototype 1 of a digital Primer presented at ECDF's Industry Day

1579619739 / AE500121

First prototype of a novel kind of digital education medium, a so-called "Digital Primer" (DP) or a "digitale Fibel" was presented to public at the Industry Day of Einstein Center Digital Future (ECDF) on 21st January 2020. Design, realization and optimization of a digital Primer is the main research & design project of Daniel D. Hromada, digital education juniorprofessor affiliated to both ECDF as well as to Faculty of Design of Berlin University of the Arts.

Distinctive innovations brought about by the DP's prototype 1 include, but are not restricted to:

- three e-paper displays (two major ones to create a book-like experience, third used for cover)
- voice & e-ink text synchronisation
- interaction mainly by means of gestures and offline automatic speech recognition systems
- A5 format
- first lesson of Bildung Digitale curriculum and first instance od Berliner Digitale Leseprobe

The aim of the DP project is to create new kind of medium which maximized positive aspects of digital education technologies (e.g. adaptive learning, qualitative evaluation, instantenous feedback) and minimizes the harmful ones (e.g. compulsive behaviour, addiction, privacy, cognitive security etc.)

Kastalia KMS presented at UdK Zukunftstag 2030

1572957235 / AE491105 , Berlin

Version v0.42 of the knowledge-management system (KMS) Kastalia has been presented as part of 2nd "Future day" organized by Berlin University of the Arts. Installation named "kastalia.medienhaus v0.42 :: 4 views" was a first public display of the system which is, since winter semester 2016 used as a singular tool for creation of collaborative presentations by study programs Kunst und Medien (KuM) and Visuelle Kommunikation (VK) of UdK's Faculty of Design.

As of 24th october 2019 kastalia's database contained 3846 "knots" ("Ding an sich") interconnected with "5226" bounds which can be displayed (as "Ding für uns") by > 79 different templates, thus generating at least 69 * 3846 = 265374 distinct and unique "views".  What was presented at UdK's Zukunfstag were four such views.

In short, Kastalia can be described as a collaborative swiss-knife of web-publishing, data-management and archivation. Asides being used as a collaborative presentation tool by all classes, workshops and labors of VK and KuM study programs,  kastalia also played a minor role in archiving the outputs of first edition of UdK2030, plays an instrumental role in creation of german-language corpus for the project of digital primer (digitale fibel) and is a backend for systems as diverse as Medienhaus cafeteria display, as well as the website You are reading in this very moment (e.g.

Article "After smartphone : Towards a new digital education artefact" published in Revue Enfance

Paris; DOI:

Article "After smartphone : Towards a new digital education artefact" is now made available by Revue Enfance, one of the most oldest (est. 1948) continental scientific journals in the field of developmental psychology and published by renowned publishing house "Presses Universitaires de France".

The article is a part of an issue 3/2019 dedicated to "Cognitive technologies for childhood" edited by Jacqueline Nadel & Charles Tijus. Its abstract being as follows:

"Non-moderate smartphone usage may induce diverse pathological states and behaviors which may potentially result in an array of syndromes and illnesses. Digital devices built for education rather than consumption and entertainment should not neglect intricacies of human physiology, ergonomy and cognition. For this reason, we present first four properties of an idealized “digital primer” artefact which could maximize the human and cultural potential of a normal elementary school pupil by means of holistic, semi-supervised interaction. Properties addressed and defined in this article are: “speech-based”, “narrative”, “circa-temporal” and “habit-disrupting”."

In its appendix, the article is also a 1st scientific publication contains a list of 23 characteristics of a digital primer, as proposed since 2016 on
