Development of a Tactile Perceived Attitude Transducer
Abstract
The objective of this effort was to design, build, and test a research device for measuring a research subject's perceived spatial orientation without the use of vision. The device consists of a multi-gimbaled structure that supports the dominant hand. A restraint system prevents slippage and shear movement. The subject indicates the perceived horizontal plane by placing his or her hand parallel to that perceived plane. This report contains a complete description of the device as well as the results of some fundamental testing on human performance with the device. In addition, the use of the device in spatial orientation research on the Dynamic Environment Simulator, a multiaxial human centrifuge, is described. The Tactile Perceived Attitude Transducer (TPAT) described herein is a simple and effective technique for reporting perceived attitude. Its accuracy, precision, and discrimination characteristics match those of more constrained or more complex devices.
