Telehaptic is the term for computer generated tactile (tangible or touch) sensations (haptics) over a network, between physically distant human beings, or between a local user and a remote location, using sensors and effectors. Microcontrollers input information from sensors, and control effectors to create human sensations as outputs.

Sensors range from pressure, temperature and kinesthetic sensing devices, to biofeedback equipment. Haptic effectors, evoking precise perceivable sensations, range from small motors, fans, heating elements, or vibrators; to micro-voltage electrodes which gently stimulate areas of the skin (creating subtle, localized, "tingling" electrotactile sensations). Telehaptic interactivity, a form of assistive technology, may involve synesthesia; e.g. sensed inputs such as breathing, brain activity, or heartbeats might be presented as gentle, precisely variable bodily sensations in any combination, including warmth, cold, vibration, pressure, etc.; opening possibilities for levels of awareness, and interpersonal communication, difficult (or impossible) to attain prior to telehaptic (and biofeedback) technologies.

One of the challenges entailed in telehaptic applications involves the requirement for stability and the synchronized functioning of multiple tasks in order to effectively operate in a real-time environment.^[1]
