Abstract:In order to display more information than the screen can accommodate at any one time, graphical user interfaces often employ clipping, i.e. a virtual space larger than the screen, which users can interactively navigate. However, this can make it hard to establish a mental model of the data. This can make interfaces difficult to navigate, especially with large amounts of content. Many Virtual Reality applications employ similar clipping patterns as 2D interfaces. Our hypothesis is that by using all the possibilities afforded by the 3D environment (e.g. the ability to move and turn your head), VR applications can be made easier to navigate than with clipping. To test this hypothesis we ran a study which compared three different interface types: Spatial (a grid), Stacked (a three-dimensional scrolling list), and Clipped (a clipped scrolling list). The content was sets of square cards with icons. For each of the conditions, participants were instructed to find a series of icons as quickly as possible. Participants found the target icons significantly faster in Spatial conditons compared to Stacked and Clipped. We found no quantitative difference between Stacked and Clipped, but in our post-experiment questionnaire participants expressed a significant preference for Stacked.
