Jens Grubert delivered the presentation on August 28th, 2013 during the 15th edition of MobileHCI, International Conference on Human-Computer Interaction with Mobile Devices and Services in Munich, Germany.
We repeated a study on the usage of a magic lens and a static peephole interface for playing a find-and-select game in a public space. While we reproduced the study setup and procedure the task was conducted in a public transportation stop with different characteristics. The results on usage duration and user preference were significantly different from those reported for previous conditions. We investigate possible causes, specifically the differences in the spatial characteristics and the social contexts in which the study took place.
