虽然已经开发了许多用于手指的可穿戴触觉显示器，例如指尖类型和手套类型的显示器，但它们的重量和大小通常阻碍手指的自由运动，特别是在考虑多手指的情况时。我们提出了一种将指尖的触觉呈现在前臂上的方法，而不是在指尖上，以解决这个问题。采用五杆机构表示两自由度作用力。我们进行了两个实验。在第一个实验中，我们将食指感觉到的压力感和水平摩擦感呈现在前臂的多个位置上，以寻找合适的呈现位置，发现手腕的掌侧部分是最佳的呈现位置。在此基础上，我们开发了食指和拇指抓取器，并进行了第二次实验，在虚拟现实环境中呈现抓取力。与没有触觉提示或振动条件下相比，使用所设计的设备时，虚拟现实中的体验真实感更好。
While many wearable tactile displays for the fingers, such as fingertip-type and glove-type displays, have been developed, their weight and size typically hinder the free movement of fingers, especially when considering the multi-finger scenario. We propose a method of presenting the haptics sensation of the fingertip on the forearm, not on the fingertip, to address this issue. A five-bar linkage mechanism was adopted to present a two-degree-of-freedom force. We conducted two experiments. In the first experiment, we presented a pressure sensation and a horizontal friction sensation perceived by the index finger to multiple sites of the forearm to search for a proper location of presentation, finding that the volar part of the wrist is optimal. On the basis of this result, we developed a device for the index finger and thumb, and conducted a second experiment to present the grasping force in a virtual reality environment. The realism of the experience in virtual reality was better when using the designed device than for no haptics cue or for vibration conditions.
