我们描述了一种计算机控制的触觉刺激器，用于人类心理物理学和猴子神经生理学研究的3-D形状感知。刺激器主要由市售部件以及一些定制部件组成，我们将根据要求提供图表。刺激器有两个组件：触觉组件和手定位器组件。触觉组件由多个刺激单元组成，这些刺激单元在被约束的手上方的笛卡尔平面中移动。每个刺激单元包含一个伺服控制的线性电机，带有一个附加的小型旋转步进电机，允许任意刺激形状通过振动，静态压痕或扫描接触皮肤。手定位器组件通过一组机动控制下的机械联动装置来修改受约束的手的构造。本设计控制第二和第三手指之间的扩展量，第四和第三手指之间的扩展，以及第三手指弯曲或伸展的程度，从而模拟与物体接触的手的不同构造。这种设计很容易修改以适应实验者的需要。由于刺激器的两个组件是独立控制的，刺激器允许参数研究的mechanoreceptive和本体感受3-D触觉形状感知的贡献。
We describe a computer-controlled tactile stimulator for use in human psychophysical and monkey neurophysiological studies of 3-D shape perception. The stimulator is constructed primarily of commercially available parts, as well as a few custom-built pieces for which we will supply diagrams upon request. There are two components to the stimulator: a tactile component and a hand positioner component. The tactile component consists of multiple stimulating units that move about in a Cartesian plane above the restrained hand. Each stimulating unit contains a servo-controlled linear motor with an attached small rotary stepper motor, allowing arbitrary stimulus shapes to contact the skin through vibration, static indentation, or scanning. The hand positioner component modifies the conformation of the restrained hand through a set of mechanical linkages under motorized control. The present design controls the amount of spread between digits two and three, the spread between digits four and three, and the degree to which digit three is flexed or extended, thereby simulating different conformations of the hand in contact with objects. This design is easily modified to suit the needs of the experimenter. Because the two components of the stimulator are independently controlled, the stimulator allows for parametric study of the mechanoreceptive and proprioceptive contributions to 3-D tactile shape perception.
