Hypotheses > H1: Users walk more when interacting with the column > more distance, more time, more positions Page 17 of 35

Hypotheses > H2: Users position themselves frontally with flat screens – not with column screens Page 18 of 35

User study Page 12 of 16

User study > Lab study, 2 days, 4 prototypes > within-subject design > Video observation, interviews and questionnaires Page 19 of 35

Survey Prototypes Page 20 of 35

Fake Prototypes Purpose: to distract from displays under investigation Page 21 of 35

Room layout Page 22 of 35

Participants > 15 participants, 10 male, 5 female, 32.7 years mean age, diverse demographic backgrounds > send them on „screen museum round tour“ Page 23 of 35

Flat Screen: Imprisonment Page 12 of 16

Column: Breaks the Prison Page 12 of 16

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 32 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. Page 33 of 35

Next Step Page 12 of 16

Next Step: Multiple users > Planned study on social interaction around columns > No sweet spot: are there less inhibitions to start performing? Page 34 of 35
