摘要:

本文提出了一种可穿戴的电触觉反馈系统,以增强接触信息的空中与虚拟物体的互动。特别是,我们建议使用电触觉反馈来呈现用户的手指和虚拟内容之间的相互渗透的距离被触摸。我们的方法包括调制感知强度(频率和脉冲宽度调制)的电触觉刺激,根据注册的相互渗透距离。在一项用户研究(N=21)中,我们评估了四种不同的渗透反馈方法的性能:仅电刺激,仅视觉,电触觉和视觉,没有渗透反馈。首先,结果表明,接触精度和准确性显着提高时,使用互穿反馈。其次,更有趣的是,当校准被优化并且用户熟悉电触觉反馈时,视觉和电触觉反馈之间没有显著差异。两者合计,这些结果表明,电触觉反馈可以是一个有效的替代视觉反馈,以提高接触信息在虚拟现实,避免需要主动视觉焦点和渲染的额外的视觉伪影。

英文摘要:

This paper presents a wearable electrotactile feedback system to enhance contact information for mid-air interactions with virtual objects. In particular, we propose the use of electrotactile feedback to render the interpenetration distance between the user's finger and the virtual content is touched. Our approach consists of modulating the perceived intensity (frequency and pulse width modulation) of the electrotactile stimuli according to the registered interpenetration distance. In a user study (N=21), we assessed the performance of four different interpenetration feedback approaches: electrotactile-only, visual-only, electrotactile and visual, and no interpenetration feedback. First, the results showed that contact precision and accuracy were significantly improved when using interpenetration feedback. Second, and more interestingly, there were no significant differences between visual and electrotactile feedback when the calibration was optimized and the user was familiarized with electrotactile feedback. Taken together, these results suggest that electrotactile feedback could be an efficient replacement of visual feedback for enhancing contact information in virtual reality avoiding the need of active visual focus and the rendering of additional visual artefacts.
