A professor at University of Southern California's Department of Computer Science has developed a wearable armband that mimics human touch. The wearable device is fitted with speaker actuators, that rise and fall in a specific timed pattern, creating a "haptic illusion". The haptic armband is controlled by an algorithm, moving the speakers one at a time to simulate the feeling of continual movement. The technology has many potential applications from automotive to social situations, where research has shown touch can decrease depression and reduce stress.
