呈现更多的触觉信息以提高用户交互能力是虚拟环境中一项重要且具有挑战性的任务。作为一种新兴的触觉反馈技术，电振动是增强系统交互性、改善用户体验的底层解决方案。然而，这种解决方案很少在虚拟环境中进行研究。在这项工作中，我们探索了一种基于电振动技术和触摸屏的新型VR交互方法，并对其进行了评估。其核心思想是在VR交互中融入一组操控手势和三种类型的电振动，帮助用户在虚拟操控中获得不同类型的触觉感知。我们提出了评估，其中我们首先比较在费茨定律任务中测量的用户性能以评估不同的电振动类型，然后在虚拟办公应用程序中评估交互式用户界面。我们的结果表明，电振动触觉反馈显着提高了交互的精度。据我们所知，这是第一个将电振动触觉反馈引入 VR 人机交互的工作，我们的工作揭示了基于电振动触摸屏的交互在虚拟环境中的潜力。
Presentation of more haptic information to improve the users interactive capability is an important and challenging task in the virtual environment. As an emerging haptic feedback technology, electrovibration is an underlying solution to enhance the systems interactivity and improve user experience. However, such a solution is rarely studied in a virtual environment. In this work, we explore a new VR interaction method based on electrovibration technology with a touch screen and conduct evaluations about it. The key idea is to incorporate a set of manipulation gestures and three types of electrovibration in the VR interaction to help users acquire different kinds of tactile perception in the virtual manipulation. We present the evaluation in which we compare user performance measured first in a Fitts law task to evaluate different electrovibration types and then in a virtual office application to assess the interactive user interface. Our results show that the precision of interactions is significantly improved with the electrovibration haptic feedback. To the best of our knowledge, this is the first work to introduce electrovibration haptic feedback into the VR human-computer interaction and our work enlightens the potential of the electrovibration touchscreen-based interaction in virtual environments.
