Haptic technology, also known as kinesthetic communication or 3D touch, refers to any technology that can create a touch experience by applying forces, vibrations or movements to the user. These technologies can be used to create virtual objects in a computer simulation, control virtual objects and improve the remote control of machines and devices (telerobotics). Haptic devices can contain tactile sensors that measure the forces exerted by the user on the interface. The word haptic from the Greek: ἁπτικός (haptikos) means "tactile, what concerns the sense of touch". Simple haptic devices are common in the form of game controllers, joysticks, and steering wheels.
Some of the key players of Haptics Technology Industry:
Texas Instruments, Nidec Corporation, Novasentis, On Semiconductor, Precision Microdrives, Microchip, AAC Technologies, Cypress Semiconductor, Alps Electric, Johnson Electric, Bluecom, Jinlong Machinery & Electronics, Immersion
Haptic technology makes it easier to study how the human sense of touch works by enabling the creation of controlled haptic virtual objects. Most researchers distinguish three sensory systems that are related to the sense of touch in humans: cutaneous, kinesthetic and haptic. All perceptions conveyed through cutaneous and kinaesthetic sensitivity are called tactical perception. The sense of touch can be classified as passive and active, and the term "haptic" is often associated with active touch to communicate or recognize objects.
One of the earliest uses of haptic technology was in large aircraft that use servomechanism systems to operate control surfaces. In lighter aircraft without servo systems, aerodynamic buffeting (vibrations) could be felt in the pilot's controls as the aircraft approached a stall. This was a useful warning of a dangerous flight condition. Servo systems are typically "one-way," which means that external forces aerodynamically exerted on the control surfaces are not perceived by the controls, resulting in a lack of this important sensory cue.
