Vibrotactile feedback aids EMG control of object manipulation.

We have previously shown that augmentative vibrotactile feedback can improve performance of a virtual object manipulation task using the finger. Here we studied the effects of vibrotactile feedback using instead electromyographic (EMG) control of object manipulation in N=6 healthy participants. Results showed that users were able to increase performance on an object manipulation task via EMG control when given augmentative vibrotactile feedback. Performance showed a strong effect of learning, which indicates further promise for utilization of this method in prosthetic hand users.
