Zusammenfassung
Past research has proposed various hand redirection techniques for virtual reality (VR). Such techniques modify a user’s hand movements and have been successfully used to enhance haptics and 3D user interfaces. Up to now, however, no unified framework exists that implements previously proposed techniques such as body warping, world warping, and hybrid methods. In this work, we present the Virtual Reality Hand Redirection Toolkit (HaRT), an open-source framework developed for the Unity engine. The toolkit aims to support both novice and expert VR researchers and practitioners in implementing and evaluating hand redirection techniques. It provides implementations of popular redirection algorithms and exposes a modular class hierarchy for easy integration of new approaches. Moreover, simulation, logging, and visualization features allow users of the toolkit to analyze hand redirection setups with minimal technical effort. We present the architecture of the toolkit along with the results of a qualitative expert study.
