Electrotactile stimulation of peripheral nerves for machine-to-human-communication

You are here

The field of human augmentation is experiencing increasing research and commercial focus. Currently human augmentation technologies are proficient at extracting information but lack diversity of means for machine-to-human communication (M2HC). Hence, n this project we investigate electrotactile stimulation of human peripheral nervous system as an alternative mean for M2HC. Electrotactile stimulation is capable of creating distinct sensations, usually in form of vibration frequency or intensity, and each distinct sensation can be used to communicate information to a trained user in form of icons. In order to maximize the number of distinct sensations that can be created we have created a hardware and software platform and are currently performng human trials to test our ideas of how best to create distinct electrotactile sensations for M2HC.
