How a Vertical Surface Supports Cross-Reality Transitional Interface Tasks at Different Virtuality Levels

摘要

Cross-Reality Transitional Interfaces support tasks that require interactions at different levels of virtuality. However, there is little knowledge on how such capabilities can be scaled on vertical and life-sized surfaces, by offering haptic feedback, transitioning the surface between physical and virtual environments, and moving the surface at room-scale. The aim of our study is to generate an empirical understanding of which combinations of mixed reality and a user-controlled movable robotic surface (resulting in four virtuality levels) are better suited to execute five tasks, which differed in terms of haptic feedback. During our user study (N=24), physical environment-physical surface was used most due to its familiarity and haptic feedback, while the virtual environment mode was experienced as more relaxing and fun, and the virtual surface mode as more convenient and safer.
