在这项研究中，我们开发了一种设备，可以在大范围内呈现高密度的触觉。该装置由多个内置针阵列的模块组成，并可驱动模块中的针压缩皮肤并呈现触觉。存在两种类型的装置，一种装置的针密度均匀地分布在整个手上（装置1），另一种装置的针密度基于2点阈值以指尖的高密度布置（装置2）。两种器械的引脚总数均为128。该装置的控制器由电-气调节器、控制电路和PC机组成。通过模拟虚拟手与物体的接触，计算出每个驱动器所施加的力。为了评估这些设备的性能，虚拟物体的三维形状识别实验进行。设备1的正确回答率和反应时间的测量结果分别为65.6%和46.1 s。器械2的结果为70.3%和40.2 s。从这些结果，有人建议，基于2点辨别阈值的呈现刺激的安排是有效的触觉识别。
In this research, we developed the device that makes it possible to present a haptic sense in a wide range of a hand with high-density. This device is composed of a plurality of modules with built-in pin arrays and pneumatically drives the pins in the module compress the skin and present the haptic sense. There is 2 type of devices, one’s density of pins evenly distributed on the whole hand (device1), and the other’s density of pins are arranged with high-density of fingertips based on a 2-point threshold (device2). The total number of pins was 128 for both devices. The Controller of the device was composed of electro-pneumatic regulators, a control circuit, and a PC. Force presented by each actuator was computed based on the simulation of contact between the virtual hand and object. In order to evaluate the performance of these devices, 3-dimensional shape recognition experiment of virtual objects was conducted. Measurement results of correct answer rate and response time were 65.6% and 46.1 s in device1. The results of device2 were 70.3% and 40.2 s. From these results, it was suggested that the arrangement of the presentation stimuli based on the 2-point discrimination threshold is effective for the tactile recognition.
