挤压感觉是人类接触中最常见和最亲密的形式之一。在本文中，我们研究了HapticClench，一种使用形状记忆合金产生挤压感觉的装置。我们根据挤压反馈的感知特性来定义它，并对HapticClench进行心理物理评估。HapticClench能够产生多达四个级别的可区分负载，在分心的情况下也能很好地工作。HapticClench具有很高的空间敏锐度，可以在手腕上生成用户可以准确识别的空间图案。我们还演示了使用HapticClench来交流活动的渐进过程，以及使用戒指和松散的手镯产生挤压感觉。
Squeezing sensations are one of the most common and intimate forms of human contact. In this paper, we investigate HapticClench, a device that generates squeezing sensations using shape memory alloys. We define squeezing feedback in terms of it perceptual properties and conduct a psychophysical evaluation of HapticClench. HapticClench is capable of generating up to four levels of distinguishable load and works well in distracted scenarios. HapticClench has a high spatial acuity and can generate spatial patterns on the wrist that the user can accurately recognize. We also demonstrate the use of HapticClench for communicating gradual progress of an activity, and for generating squeezing sensations using rings and loose bracelets.
