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…
Supra-threshold control of peripheral LOD
Benjamin Watson, Neff Walker, Larry F Hodges
Level of detail (LOD) is widely used to control visual feedback in interactive applications. LOD control is typically based on perception at threshold - the conditions in which a s…
Managing level of detail through head-tracked peripheral degradation: a model and resulting design principles
Benjamin Watson, Neff Walker, Larry F Hodges
Previous work has demonstrated the utility of reductions in the level of detail (LOD) in the periphery of head-tracked, large field of view displays. This paper provides a psychoph…
An evaluation of level of detail degradation in head-mounted display peripheries
Benjamin Watson, Neff Walker, Larry F Hodges +1
A paradigm for the design of systems that manage level of detail in virtual environments is proposed. As an example of the prototyping step in this paradigm, a user study was perfo…
