Hypotheses > H1: Users walk more when interacting with the column > more distance, more time, more positions
SLIDE 22
Page 18 of 35
Hypotheses > H2: Users position themselves frontally with flat screens – not with column screens

Columns > are encountered laterally. Design for one-hand use. > are for passers-by. Design for walking. > are only semi-framed. Design for variable positions.

Page 33 of 35
Flat screens > are faced frontally. Design for both-hand use. > are for standing still at a fixed spot for longer times. More complexity is possible.
