Abstract

Haptic feedback is essential for daily activities, since it provides us with the ability to become aware of our surroundings. Modern approaches that provide haptic feedback focus mainly on robotic manipulators, vibrators, and tactors. This type of feedback tends to be cumbersome and limited to a small number of contact points. On the contrary, electro-tactile displays are compact, portable, non expensive and wearable, and recent discoveries demonstrate that naturalistic sensations of touch can be provided by electrical stimulation of peripheral nerves. The long-term goal of this work is to enhance sensory perception in artificial interfaces for various applications including neuroprothestics, teleoperation, surgical training of physicians in virtual environment and providing tactile feedback for video-game users in virtual
reality environments.
The direct goal of this work is to develop techniques to identify and extract EEG features that are markers for real world haptic interactions. Moreover, develop a closed-loop system guided by EEG to control sensory stimulation for enhanced spatial presence.
Even though a number of methods have been developed to measure perception of spatial presence and provide sensory feedback in virtual reality environments, there is currently no closed-loop control of sensory stimulation that couple the spatial presence measures to adaptive adjustment of stimulation levels. More specifically, in this work we aim to develop an EEG-guided closed loop electro-tactile stimulation model that adaptively improve haptic presence in virtual environments and for neuroprothestics.
