在虚拟环境中比较手势和游戏手柄界面的运动
Comparing Hand Gestures and a Gamepad Interface for Locomotion in Virtual Environments
摘要：
手势是虚拟环境中一种新的、很有前途的运动接口。虽然以前的几项研究提出了不同的手势虚拟运动，很少有人知道他们的差异，在虚拟运动任务的性能和用户偏好。在本文中，我们提出了三种不同的手势接口和运动的算法，这三种手势分别被称为手指距离手势，手指数手势和手指敲击手势。这些手势的灵感来自于先前对基于手势的运动界面的研究，并且是人们在日常生活中熟悉的典型手势。在本研究中实现这些手势界面使我们能够系统地比较这些手势之间的差异。此外，为了比较这些手势与使用游戏手柄的运动界面的可用性，我们还设计并实现了一个基于Xbox One控制器的游戏手柄界面。我们进行了实证研究，比较这四个接口，通过两个虚拟运动任务。由于对新型冠状病毒疫情的担忧，与会者使用了桌面设置，而不是共用盔装显示器。通过这些任务，我们评估了这些界面在速度控制和航点导航方面的性能和用户偏好。结果表明，用户偏好和手指距离手势的性能接近游戏手柄界面。手指数手势也具有与手指距离手势接近的性能和用户偏好。我们的研究表明，手指距离手势和手指数手势是非常有前途的虚拟运动接口。我们还讨论了手指轻敲手势需要进一步改进，才能用于虚拟行走。
英文摘要：
Hand gesture is a new and promising interface for locomotion in virtual environments. While several previous studies have proposed different hand gestures for virtual locomotion, little is known about their differences in terms of performance and user preference in virtual locomotion tasks. In the present paper, we presented three different hand gesture interfaces and their algorithms for locomotion, which are called the Finger Distance gesture, the Finger Number gesture and the Finger Tapping gesture. These gestures were inspired by previous studies of gesture-based locomotion interfaces and are typical gestures that people are familiar with in their daily lives. Implementing these hand gesture interfaces in the present study enabled us to systematically compare the differences between these gestures. In addition, to compare the usability of these gestures to locomotion interfaces using gamepads, we also designed and implemented a gamepad interface based on the Xbox One controller. We conducted empirical studies to compare these four interfaces through two virtual locomotion tasks. A desktop setup was used instead of sharing a head-mounted display among participants due to the concern of the Covid-19 situation. Through these tasks, we assessed the performance and user preference of these interfaces on speed control and waypoints navigation. Results showed that user preference and performance of the Finger Distance gesture were close to that of the gamepad interface. The Finger Number gesture also had close performance and user preference to that of the Finger Distance gesture. Our study demonstrates that the Finger Distance gesture and the Finger Number gesture are very promising interfaces for virtual locomotion. We also discuss that the Finger Tapping gesture needs further improvements before it can be used for virtual walking.
