Open Data Exploration in Virtual Reality: a Comparative Study of Input Technology
Virtual reality(2019)
Abstract
In this article, we compare three different input technologies (gamepad, vision-based motion controls, room-scale) for an interactive virtual reality (VR) environment. The overall system is able to visualize (open) data from multiple online sources in a unified interface, enabling the user to browse and explore displayed information in an immersive VR setting. We conducted a user interaction study ( n = 24 ; n = 8 per input technology, between-group design) to investigate experienced workload and perceived flow of interaction. Log files and observations allowed further insights and comparison of each condition. We have identified trends that indicate user preference of a visual (virtual) representation , but no clear trends regarding the application of physical controllers (over vision-based controls) , in a scenario that encouraged exploration with no time limitations.
