We present EnhancedTouch, a novel bracelet-type wearable device for facilitating human-human physical touch. In particular, we aim to support children with autism spectrum disorder (ASD), who often exhibit particular communication patterns, such as lack of physical touch. EnhancedTouch is a unique device that can measure human-human touch events and provide visual feedback to augment touch interaction. We employ personal area network (PAN) technology for communication with partner devices via modulated electrical current flowing through the users’ hands. Our user study shows that the visual feedback provided by the developed bracelet motivates children with ASD to touch one another. Moreover, EnhancedTouch offers a function to record the time and duration of a touch event as well as the identity of the touched person. This allows us to identify and evaluate intervention based on physical touch in a quantitative manner. (ACM CHI 2016)
