Description

Prior work has explored transition visualizations between VR environments, or on specific interaction techniques for transferring objects from VR <-> AR views. However, there has been less attention on what are the more effective transitions across the reality-virtuality continuum. The focus of this work would be to (a) identify suitable MR transitions (b) create a mapping to common tasks where such transitions may be applicable (e.g., keyboard typing) (c) prototype different transitions, from R-->AR-->AV--VR, and vice versa: VR-->AV-->AR--R, and empirically investigating different parameters of each (d) run a user evaluation to assess perceived UX. comfort, sickness, etc. This project extends the work in Keep it simple? Evaluation of Transitions VR, by exploring MR transitions, instead of only across different VR environments. Evaluation metrics will involve both objective and subjective measures.

RQ1: What are the most effective methods for transitioning users across the reality-virtuality spectrum?

RQ2: How do these transition visualizations influence user experience, user physiological state, workload, and acceptance across tasks?
