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…
A tangible user interface for assessing cognitive mapping ability
Ehud Sharlin, Benjamin Watson, Steve Sutphen +3
Wayfinding, the ability to recall the environment and navigate through it, is an essential cognitive skill relied upon almost every day in a person's life. A crucial component of w…
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…
