Jens Grubert deliver the presentation on September 29th, 2012 during the 14th edition of MobileHCI, International Conference on Human-Computer Interaction with Mobile Devices and Services in San Francisco, California, USA.

ABSTRACT:
Magic lens and static peephole interfaces are used in numerous consumer mobile phone applications such as Augmented Reality browsers, games or digital map applications in a variety of contexts including public spaces. Interface performance has been evaluated for various interaction tasks involving spatial relationships in a scene. However, interface usage outside laboratory conditions has not been considered in depth in the evaluation of these interfaces.
We present findings about the usage of magic lens and static peephole interfaces for playing a find-and-select game in a public space and report on the reactions of the public audience to participants‟ interactions.
Contrary to our expectations participants favored the magic lens over a static peephole interface despite tracking errors, fatigue and potentially conspicuous gestures. Most passersby did not pay attention to the participants and vice versa. A comparative laboratory experiment revealed only few differences in system usage.
