Title
The utility of Magic Lens interfaces on handheld devices for touristic map navigation
Abstract
This paper investigates the utility of the Magic Lens metaphor on small screen handheld devices for map navigation given state of the art computer vision tracking. We investigate both performance and user experience aspects. In contrast to previous studies a semi-controlled field experiment ( n = 18 ) in a ski resort indicated significantly longer task completion times for a Magic Lens compared to a Static Peephole interface in an information browsing task. A follow-up controlled laboratory study ( n = 21 ) investigated the impact of the workspace size on the performance and usability of both interfaces. We show that for small workspaces Static Peephole outperforms Magic Lens. As workspace size increases performance gets equivalent and subjective measurements indicate less demand and better usability for Magic Lens. Finally, we discuss the relevance of our findings for the application of Magic Lens interfaces for map interaction in touristic contexts. Investigation of Magic Lens and Static Peephole on smartphones for maps.Two experiments: semi-controlled field experiment in a ski resort and lab study.For A0 sized posters Magic Lens is slower and less preferred.For larger workspace sizes performance between interfaces is equivalent.Magic Lens interaction results in better usability for large workspaces.
