过去的研究已经提出了各种虚拟现实(VR)的手重定向技术。这样的技术修改用户的手部运动,并且已经成功地用于增强触觉和3D用户界面。然而,到目前为止,还没有一个统一的框架来实现以前提出的技术,如身体扭曲,世界扭曲和混合方法。在这项工作中,我们提出了虚拟现实手重定向工具包(哈特),一个开源的框架开发的统一引擎。该工具包旨在支持新手和专家VR研究人员和从业者实施和评估手部重定向技术。它提供了流行的重定向算法的实现,并公开了一个模块化的类层次结构,以便轻松集成新方法。此外,模拟,日志记录和可视化功能允许工具包的用户以最小的技术工作来分析手重定向设置。我们提出的工具包的架构沿着与定性专家研究的结果。
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.
