How to fill M2H protocol :: Digital devices in the public space

Fill the header of the protocol before entering the transport.

Systematically proceed from one end of transport to the other.

Do not hurry, quality (truthfulness of data) is more important than quantity.

Be discrete, smile, use Your peripheral vision.

Be rigorous :: Do not log one subject more than once even if their state changes. Try not to exclude anyone.

At every station, wait a while until people sit down. Record only sitting and standing people.

Note down any unexpected event (either environmental or intrapersonal) on the other (blank) side of the paper.
Prefer information about media usage instead of interaction/misc. information.
