ABSTRACT
The purpose of this paper is to investigate a concept called virtual ability simulation (VAS) for people with disability in a virtual reality (VR) environment. In a VAS people with disabilities perform tasks that are made easier in the virtual environment (VE) compared to the real world. We hypothesized that putting people with disabilities in a VAS will increase confidence and enable more efficient task completion than without a VAS. To investigate this hypothesis, we conducted a within-subjects experiment in which participants performed a virtual task called "kick the ball" in two different conditions: a no gain condition (i.e., same difficulty as in the real world) and a rotational gain condition (i.e., physically easier than the real world but visually the same). The results from our study suggest that VAS increased participants' confidence which in turn enables them to perceive the difficulty of the same task easier.

Effects of dynamic field-of-view restriction on cybersickness and presence in HMD-based virtual reality
AbstractThe phenomenon of cybersickness is currently hindering the mass market adoption of head-mounted display (HMD) virtual reality (VR) technologies. This study examined the effects of dynamic field-of-view (FOV) restriction on the cybersickness ...
Effects of steering locomotion and teleporting on cybersickness and presence in HMD-based virtual reality
AbstractWhile head-mounted display-based virtual reality (VR) can produce compelling feelings of presence (or “being there”) in its users, it also often induces motion sickness. This study compared the presence, cybersickness and perceptions of self-...
