Haptic Perceptual Instruments

触觉神经系统可以让人知道附近的物体 以及通过与身体接触的表面。 而不必 看一个物体，一个人可以得到一些印象， 它的属性通过持有它和挥舞它。这项研究 概念化的触觉子系统在挥舞作为一种测量 这是一种巧妙地利用合法资产的工具， 作为物体抵抗力的恒定模式， 不同方向的旋转。 实验将检验 物体长度的触觉感知， 组件、方向和形状。 他们将这样做， 一个物体或两个物体握在手中的情况。 人 在实验中将通过调整（可见）可移动 表面或指针来量化感知属性。 的 实验将试图确定力学变量 它与物体的几何特性有关， 手持物体，并表明挥舞必须在一个 明确的，虽然复杂的方式，以使一个特定的属性， 被感知。 识别这些与手相关的能力， 他们的物理基础将有助于设计感觉和运动 假肢，机器人肢体，和智能工具。 了解 触觉感知工具的形式和功能将进一步发展 特殊目的认知机制理论。

The haptic nervous system allows one to know about nearby objects and surfaces by means of contact with the body. Without having to look at an object, a person can get an impression of some of its properties by holding it and wielding it. This research conceptualizes the haptic subsystem in wielding as a measurement instrument which capitalizes smartly on lawful regularities, such as the constant pattern of the resistances of an object to rotations in different directions. The experiments will examine the haptic perception of object length, angular separation of components, orientations, and shape. They will do so for conditions where one object or two are held in the hand. People in the experiments will respond by adjusting (visible) movable surfaces or pointers to quantify the perceived properties. The experiments will attempt to identify the mechanical variables that relate uniquely to the perceived geometric properties of the hand-held objects, and to show that wielding must be done in a definite though complex way in order for a particular property to be perceived. Identifying these hand-related capabilities and their physical basis will help the design of sensory and motor prostheses, robotic limbs, and clever tools. Understanding the form and function of haptic perceptual instruments will advance the theory of special purposes cognitive mechanisms.
