A Comparison of Haptic and Auditory Feedback as a Warning Signal for Slip in Tele-Operation Scenarios

摘要

Abstract Slip feedback is an important cue in everyday object manipulation, but it is generally missing in tele-operation systems. To test the usefulness of simple, abstract types of feedback that warn the user about slip events, we tested the effect of auditory and haptic vibration feedback in a tele-operation task. Participants were asked to hold an object in a remote robot hand, and the force profiles that they exerted in response to slip events were measured. Haptic feedback did not significantly change the response characteristics, but auditory feedback did significantly improve response latency. A small but significant difference between haptic and auditory reaction times (60 ms) found in our control experiment might explain the difference between the feedback types.
