Multi-sensory haptic cues, which contain several types of tactile stimuli that are presented concurrently to the user, have been shown to be useful for conveying information-rich cues. One limitation of multi-sensory cues is that user perception of individual cue components can be hindered by more salient components of the composite cue. In this article, we investigate how amplitude and distance between cues affect the perception of multi-sensory haptic cues. Specifically, participants’ absolute threshold perception of stretch cues was measured in the presence of interfering squeeze cues using a modular testbed. We evaluated ten conditions of varying interference amplitude and distance between cues. We found that interference cue amplitude and distance between cues both have a statistically significant effect on the absolute perception of stretch cues. As interference cue amplitude increases, and as distance between cues decreases, absolute perception of stretch cues worsens. These results inform design considerations for future wearable multi-sensory haptic devices, so that cue salience can be maximized and interference effects minimized.

干扰提示间隔距离和幅度对皮肤拉伸触觉检测的影响


多感官触觉提示包含同时呈现给用户的多种类型的触觉刺激，已被证明对于传达信息丰富的提示非常有用。多感官提示的一个局限性是，用户对单个提示组件的感知可能会受​​到复合提示中更显着的组件的阻碍。在本文中，我们研究了提示之间的幅度和距离如何影响多感官触觉提示的感知。具体来说，使用模块化测试台在存在干扰挤压线索的情况下测量参与者对伸展线索的绝对阈值感知。我们评估了十种不同干扰幅度和线索之间距离的条件。我们发现干扰提示幅度和提示之间的距离都对拉伸提示的绝对感知有统计显着影响。随着干扰提示幅度的增加以及提示之间距离的减小，拉伸提示的绝对感知会恶化。这些结果为未来可穿戴多感官触觉设备的设计考虑提供了参考，从而可以最大限度地提高提示的显着性并最大限度地减少干扰效应。
