Folding Rays: a Bimanual Occluded Target Interaction Technique

TL;DR

Folding rays is a novel bimanual interaction technique in virtual reality that enables users to select occluded targets without physical navigation by bending rays at user-defined points, enhancing interaction efficiency.

Contribution

This paper introduces the folding rays technique, allowing occluded target selection in VR without environment manipulation, improving upon existing ray-casting methods.

Findings

Enables selection of occluded targets without environment navigation

Allows rays to bend at user-defined points for better targeting

Potential integration with teleportation for improved VR interaction

Abstract

As Virtual Reality becomes commonplace in the world, it is important for developers to focus on user interaction with the virtual world. Currently, there are limitations to some selection and navigation techniques that have not yet been completely overcome. Focusing specifically on enhancing ray-casting, we present the advanced technique of folding rays which allows for the selection of occluded targets without any unnecessary physical navigation around a virtual environment. By improving upon current approaches, our technique allows for the selection of these targets without any manipulation of the virtual environment itself using rays that can bend at user-determined points. With their potential to be used in conjunction with teleportation as a virtual navigation technique, folding rays can be used in a variety of scenarios to enhance a user's interactive experience in virtual environments.
