Exploring the potential of telehaptic communication between multiple users, Human Stitches is a pair of wireless bodysuits outfitted with 120 haptic zones. Each zone contains a sensor for input and an actuator for feedback.
The suits are designed to mirror each other (a touch on one suit triggers and actuator in the same location on the other) or they can be controlled remotely via a mobile device.
The project is a wonderful research tool to examine various use cases for haptic communication. More detailed information can be found in this paper on Telehaptic Awareness.
