The user's palm plays an important role in object detection and manipulation. The design of a robust multi-contact tactile display must consider the sensation and perception of of the stimulated area aiming to deliver the right stimuli at the correct location. To the best of our knowledge, there is no study to obtain the human palm data for this purpose. The objective of this work is to introduce the method to investigate the user's palm sensations during the interaction with objects. An array of fifteen Force Sensitive Resistors (FSRs) was located at the user's palm to get the area of interaction, and the normal force delivered to four different convex surfaces. Experimental results showed the active areas at the palm during the interaction with each of the surfaces at different forces. The obtained results can be applied in the development of multi-contact wearable tactile and haptic displays for the palm, and in training a machine-learning algorithm to predict stimuli aiming to achieve a highly immersive experience in Virtual Reality.

用户手掌对物体的触觉感知，用于开发多接触可穿戴触觉显示器

用户的手掌在物体检测和操纵中起着重要作用。强大的多触点触觉显示器的设计必须考虑受刺激区域的感觉和感知，旨在在正确的位置提供正确的刺激。据我们所知，没有研究为此目的获取人类手掌数据。这项工作的目的是介绍在与对象交互过程中调查用户手掌感觉的方法。一组 15 个力敏电阻器 (FSR) 位于用户的手掌上以获得交互区域，并将法向力传递到四个不同的凸面。实验结果表明，在以不同的力与每个表面相互作用期间，手掌处的活动区域。
