During interaction with remote environments, the operator may benefit from the addition of force feedback to the ubiquitous visual feedback. However, the apparatus required for reactive force feedback (feedback which imposes the remote environment's motion-constraints on the user by applying joint torques) is cumbersome and expensive, especially when implemented in conjunction with high degree-offreedom precision joint motion sensing. Non-reactive, tactile feedback can provide similar information, and can be implemented at much lower cost. The purposes of this research were (1)todesign and demonstrate an inexpensive tactile feedback system, and (2) to determine the extent to which such a system could aid in the performance of a simple teleoperation task. After some experimentation with some different display technologies, and preliminary design, a vibrotactile display was chosen because of its low weight, size, and low cost. The final design consisted of two voice-coils, one each for the thumb and the index finger, which were driven by a 250 Hz variableamplitude signal produced by an analog electronics unit which was controlled by a PC. Experimental results are provided to show that the addition of the tactile display provides a small but significant improvement in manual tracking performance over the use of the visual display alone, and that the tracking task may be performed with only the tactile display. In further experiments the tactile display is compared with reactive force-feedback and is shown to confer most of the reactive display's performance improvement over tracking with only a visual display.
