Adaptive Frameless Rendering
Abhinav Dayal, Cliff Woolley, Benjamin Watson +1
We propose an adaptive form of frameless rendering with the potential to dramatically increase rendering speed over conventional interactive rendering approaches. Without the rigid…
A virtual airplane for fear of flying therapy
Larry F Hodges, Barbara O Rothbaum, Benjamin Watson +2
Fear of flying is a serious problem that affects millions of individuals. Exposure therapy for fear of flying is an effective therapy technique. However, exposure therapy is also e…
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…
