摘要

这项研究的重点是开发一种基于躯干的触觉显示器,该显示器可用于向人类操作员提供导航提示。对这种显示器的要求是它可以佩戴在移动操作员身上,重量轻,坚固耐用。为了实现这些目标,两种触觉背心正在开发中,一种基于小型电动机,另一种基于收缩形状记忆合金(SMA)纤维。评估了四种机电致动器在背心中的使用情况,并为初始原型选择了一种小型振动电机。制作3/spl倍/3阵列用于心理物理测试,放置于下背部。所有被试在感知因子激活方向上都达到了较高的准确性。制作了一种基于SMA致动器的因子阵列并进行了测试,结果表明该低带宽装置可以在躯干上产生可感知的触觉输入。

Development of a tactile vest
This research is focused on the development of a torso-based haptic display that can be used to present navigational cues to a human operator. The requirements for this display are that it can be worn on a mobile operator, is light weight and robust. Two tactile vests are being developed to meet these objectives, one based on small electric motors and the other on contractile shape-memory alloy (SMA) fibers. Four electromechanical actuators were evaluated for use in the vest and a small vibration motor was selected for the initial prototype. A 3/spl times/3 array was fabricated for psychophysical testing and positioned on the lower back. High accuracy in perceiving the direction of factor activation was achieved by all subjects in this task. A factor array based on SMA actuators was fabricated and tested and results indicate that this low-bandwidth device can generate tactile inputs on the torso that are perceptible.
