GlanXR: A Hands-Free Fast Switching System for Virtual Screens

To date, virtual and augmented reality technologies enable users to view multiple, large virtual screens in their workspaces. However, users must frequently rotate their heads to shift focus among these screens. This paper presents GlanXR, a fast and robust handsfree approach for screen switching in virtual reality. GlanXR incorporates a peripheral interface that remains fixed within the user’s view, in which screens can be dynamically selected based on the user’s eye-head position beyond an adaptive range. Additionally, the user triggers the switch to the screen chosen by making an opposing head rotation in the direction of the eye-head position to minimize false triggers. We conducted an experiment including a fast-switching scenario and a working simulation scenario with 24 participants to assess the effectiveness of GlanXR as compared to a baseline (taskbar), an expansive multi-screen setup, and a gazebased screen selection method. The results indicate that GlanXR facilitates precise screen-switching, minimizes the necessity for head rotation, and allows users to maintain a neutral head position.
