Effects of variation in system responsiveness on user performance in virtual environments
Benjamin Watson, Neff Walker, William Ribarsky +1
System responsiveness (SR) is defined as the elapsed time until a system responds to user control. SR fluctuates over time, so it must be described statistically with mean (MSR) an…
Evaluation of the effects of frame time variation on VR task performance
Benjamin Watson, Victoria Spaulding, Neff Walker +1
We present a first study of the effects of frame time variations, in both deviation around mean frame times and period of fluctuation, on task performance in a virtual environment…
Managing level of detail through peripheral degradation: Effects on search performance with a head-mounted display
Benjamin Watson, Neff Walker, Larry F Hodges +1
Two user studies were performed to evaluate the effect of level-of-detail (LOD) degradation in the periphery of head-mounted displays on visual search performance. In the first stu…
On tangible user interfaces, humans and spatiality
Ehud Sharlin, Benjamin Watson, Yoshifumi Kitamura +2
Like the prehistoric twig and stone, tangible user interfaces (TUIs) are objects manipulated by humans. TUI success will depend on how well they exploit spatiality, the intuitive s…
A wireless, inexpensive optical tracker for the CAVE
Ehud Sharlin, Pablo Figueroa, Mark Green +1
CAVE displays offer many advantages over other virtual reality (VR) displays, including a large, unencumbering viewing space. Unfortunately, the typical tracking subsystems used wi…
Spatial tangible user interfaces for cognitive assessment and training
Ehud Sharlin, Yuichi Itoh, Benjamin Watson +4
This paper discusses Tangible User Interfaces (TUIs) and their potential impact on cognitive assessment and cognitive training. We believe that TUIs, and particularly a subset that…
