Does (Multi-)Touch Aid Users’ Spatial Memory and Navigation in ‘Panning’ and in ‘Zooming & Panning’ UIs?

2012, Jetter, Hans-Christian, Leifert, Svenja, Gerken, Jens, Schubert, Sören, Reiterer, Harald

Recent findings from Embodied Cognition reveal strong effects of arm and hand movement on spatial memory. This suggests that input devices may have a far greater influence on users’ cognition and users’ ability to master a system than we typically believe – especially for spatial panning or zooming & panning user interfaces. We conducted two experiments to observe whether multi-touch instead of mouse input improves users’ spatial memory and navigation performance for such UIs. We observed increased performances for panning UIs but not for zooming & panning UIs. We present our results, provide initial explanations and discuss opportunities and pitfalls for interaction designers.

Zooming not Zapping : Demonstrating the ZOIL User Interface Paradigm for ITV Applications

2008, Jetter, Hans-Christian, Engl, Andreas, Schubert, Sören, Reiterer, Harald

This paper introduces the ZOIL (Zoomable Object-Oriented Information Landscape) user interface paradigm, which is aimed at seamlessly integrating media services and content of all kinds into novel intuitive and natural visual user interfaces. In order to provide an intriguing user experience, ZOIL interfaces combine the principles of objectoriented and zoomable user interfaces with information visualization techniques. To demonstrate ZOIL s benefit for the ITV domain, we will provide visitors with an interactive firsthand experience of ZOIL s alternate interface physics, visual information exploration and usability.
