Exploiting Spatial Memory and Navigation Performance in Dynamic Peephole Environments
Jens Müller · 2014
One way to handle the representation of (and the navigation in) datasets that exceed the available display space is by provisioning movable viewports which display a subset of the entire space. Unlike static viewports, where the information space is moved (e.g. by panning), dynamic viewports -- so-called dynamic peepholes -- allow the user to move the viewport in physical space and thereby enable egocentric navigation in digital information spaces. In my research I investigate how information spaces and the navigation with peepholes need to be designed in order to exploit spatial memory and navigation performance. In particular I focus on the interplay between the physical and the digital aspects and how they affect user performance. For study purposes I use a tablet as a dynamic peephole. I will conduct controlled studies in our research lab, which is equipped with 24 infrared cameras and enable a precise tracking of the lab environment.
