本文提出了一种用于静电视觉触觉显示器的接触垫机构，它既能为垂直推力提供柔软感，又能为侧向探索提供横向反作用力。作者提出了一种触觉显示器，可以通过视觉屏幕上的接触垫提供带有电粘连的侧向力反馈。通过修改垫的机构以变形以包裹手指，可以扩展触觉显示以提供垂直推送的柔软感。该机构利用电粘着制动器作为法向推力的函数进行控制，以接触面积控制的方式控制提供的柔软感。通过模型分析和样机实验，讨论了该机构的特点。心理物理实验验证了所提出的概念。
This paper proposes a mechanism of a contact pad for an electrostatic visuo-haptic display that can provide softness sensation to vertical pushing as well as lateral reaction force to lateral exploration. The authors have proposed a haptic display that can provide lateral force feedback with electroadhesion via contact pads on a visual screen. By modifying the mechanism of the pad to deform to enwrap a finger, the haptic display can be extended to provide softness sensation to vertical pushing. By using electroadhesion brake which is controlled as function of the normal pushing force, the mechanism can control the provided softness sensation in the contact area control manner. The characteristics of the proposed mechanism is discussed through the model analysis and the experiment with the fabricated prototype. Psychophysical experiment verifies the proposed concept.
