Abstract

When visual and auditory are not available on some occasions, tactile rendering systems can provide an effective way for people to obtain information. A wearable tactile information expression system based on electrotactile rendering is designed and developed. Because this is a kind of passive stimulation, dynamic display method which displayed one electrode at a time according to some specific orders is necessary to improve the effect of perception of the proposed system and this method is applied on an 8 × 8 spherical electrode array to obtain information through people’s wrist. Three experiments including voltage threshold experiment, spatial resolution experiment and simple pattern recognition experiment are implemented and the average success rate of recognition is above 90%. These experimental results verify the effectiveness of the proposed system and lay a foundation for identifying complicated patterns in the future.
