Haptic devices may incorporate tactile sensors that measure forces exerted by the user on the interface. The word haptic, from the Greek: ἁπτικός (haptikos), means "tactile, pertaining to the sense of touch". Simple haptic devices are common in the form of game controllers, joysticks, and steering wheels.

Haptic technology facilitates investigation of how the human sense of touch works by allowing the creation of controlled haptic virtual objects. Most researchers distinguish three sensory systems related to sense of touch in humans: cutaneous, kinaesthetic and haptic.<ref>Biswas, S.; Visell, Y. (2021).

History

One of the earliest applications of haptic technology was in large aircraft that use servomechanism systems to operate control surfaces.<ref>Loftin, Lawrence K Jr. (1985). "Quest for Performance: The Evolution of Modern Aircraft" (PDF). NASA Scientific and Technical Information Branch. pp. Chapter 10. Retrieved 2019-07-19.</ref> In lighter aircraft without servo systems, as the aircraft approached a stall, the aerodynamic buffeting (vibrations) was felt in the pilot's controls. This was a useful warning of a dangerous flight condition. Servo systems tend to be "one-way", meaning external forces applied aerodynamically to the control surfaces are not perceived at the controls, resulting in the lack of this important sensory cue. To address this, the missing normal forces are simulated with springs and weights. The angle of attack is measured, and as the critical stall point approaches a stick shaker is engaged which simulates the response of a simpler control system. Alternatively, the servo force may be measured and the signal directed to a servo system on the control, also known as force feedback. Force feedback has been implemented experimentally in some excavators and is useful when excavating mixed material such as large rocks embedded in silt or clay. It allows the operator to "feel" and work around unseen obstacles.<ref>Morosi, Federico; Rossoni, Marco; Caruso, Giandomenico (2019). "Coordinated control paradigm for hydraulic excavator with haptic device". Automation in Construction. 105: 102848. doi:10.1016/j.autcon.2019.102848. hdl:11311/1096219. S2CID 191138728.</ref>

In the 1960s, Paul Bach-y-Rita developed a vision substitution system using a 20x20 array of metal rods that could be raised and lowered, producing tactile "dots" analogous to the pixels of a screen. People sitting in a chair equipped with this device could identify pictures from the pattern of dots poked into their backs.<ref>Bach-Y-Rita, Paul; Collins, Carter C.; Saunders, Frank A.; White, Benjamin; Scadden, Lawrence (1969).

In 1995, Thomas Massie developed the PHANToM (Personal HAptic iNTerface Mechanism) system. It used thimble-like receptacles at the end of computerized arms into which a person's fingers could be inserted, allowing them to "feel" an object on a computer screen.<ref>5587937, Massie, Thomas H. & Salisbury, Jr, "United States Patent: 5587937 - Force reflecting haptic interface", issued December 24, 1996 </ref>

In 1995, Norwegian Geir Jensen described a wristwatch haptic device with a skin tap mechanism, termed Tap-in. The wristwatch would connect to a mobile phone via Bluetooth, and tapping-frequency patterns would enable the wearer to respond to callers with selected short messages.<ref>"Apple-klokka ble egentlig designet i Norge for 20 år siden".

In 2015, the Apple Watch was launched. It uses skin tap sensing to deliver notifications and alerts from the mobile phone of the watch wearer.

Types of mechanical touch sensing

Human sensing of mechanical loading in the skin is managed by Mechanoreceptors. There are a number of types of mechanoreceptors but those present in the finger pad are typically placed into two categories. Fast acting (FA) and slow acting (SA). SA mechanoreceptors are sensitive to relatively large stresses and at low frequencies while FA mechanoreceptors are sensitive to smaller stresses at higher frequencies. The result of this is that generally SA sensors can detect textures with amplitudes greater than 200 micrometers and FA sensors can detect textures with amplitudes less than 200 micrometers down to about 1 micrometer, though some research suggests that FA can only detect textures smaller than the fingerprint wavelength.<ref>Fagiani, R., & Barbieri, M. (2016). A contact mechanics interpretation of the duplex theory of tactile texture perception. Tribology International, 101, 49-58.</ref> FA mechanoreceptors achieve this high resolution of sensing by sensing vibrations produced by friction and an interaction of the fingerprint texture moving over fine surface texture.<ref>Scheibert, J., Leurent, S., Prevost, A., & Debrégeas, G.

Implementation

See the sub-sections under applications for examples.

Haptic feedback

Haptic feedback (often shortened to just haptics) is controlled vibrations at set frequencies and intervals to provide a sensation representative of an in-game action; this includes 'bumps', 'knocks', and 'tap' of one's hand or fingers.

The majority of electronics offering haptic feedback use vibrations, and most use a type of eccentric rotating mass (ERM) actuator, consisting of an unbalanced weight attached to a motor shaft. As the shaft rotates, the spinning of this irregular mass causes the actuator and the attached device to shake. Piezoelectric actuators are also employed to produce vibrations, and offer even more precise motion than LRAs, with less noise and in a smaller platform, but require higher voltages than do ERMs and LRAs.<ref>Texas Instruments (2017).

Ultrasound

Focused ultrasound beams can be used to create a localized sense of pressure on a finger without touching any physical object.

Another form of tactile feed back results from active touch when a human scans (runs their finger over a surface) to gain information about a surfaces texture. A significant amount of information about a surfaces texture on the micro meter scale can be gathered through this action as vibrations resulting from friction and texture activate mechanoreceptors in the human skin. Towards this goal plates can be made to vibrate at an ultrasonic frequency which reduces the friction between the plate and skin.<ref>Basdogan, C.; Giraud, F.; Levesque, V.; Choi, S.

The first electrically actuated teleoperators were built in the 1950s at the Argonne National Laboratory by Raymond Goertz to remotely handle radioactive substances.<ref>Goertz, R.C. (1952-11-01). "Fundamentals of general purpose remote manipulators". Nucleonics. 10: 36–42.</ref> Since then, the use of force feedback has become more widespread in other kinds of teleoperators, such as remote-controlled underwater exploration devices.

Devices such as medical simulators and flight simulators ideally provide the force feedback that would be felt in real life. Simulated forces are generated using haptic operator controls, allowing data representing touch sensations to be saved or played back.<ref>Feyzabadi, S.; Straube, S.; Folgheraiter, M.; Kirchner, E.A.; Su Kyoung Kim; Albiez, J.C., "Human Force Discrimination during Active Arm Motion for Force Feedback Design," IEEE Transactions on Haptics, vol. 6, no. 3, pp. 309, 319, July–Sept. 2013</ref>

Teledildonics

Haptic feedback is used within teledildonics, or "sex-technology", in order to remotely connect sex toys and allow users to engage in virtual sex or allow a remote server to control their sex toy. The term was first coined by Ted Nelson in 1975, when discussing the future of love, intimacy and technology.[citation needed] In recent years, teledildonics and sex-technology have expanded to include toys with a two-way connection that allow virtual sex through the communication of vibrations, pressures and sensations. Many "smart" vibrators allow for a one-way connection either between the user, or a remote partner, to allow control of the toy.

Video games

Rumble packs for controllers, such as this Dreamcast Jump Pack, provide haptic feedback through users' hands.

Haptic feedback is commonly used in arcade games, especially racing video games. In 1976, Sega's motorbike game Moto-Cross,<ref name=Moto-Cross>Template:KLOV game</ref> also known as Fonz,<ref name=Fonz>Template:KLOV game</ref> was the first game to use haptic feedback, causing the handlebars to vibrate during a collision with another vehicle.<ref>Mark J.P. Wolf (2008), The video game explosion: a history from PONG to PlayStation and beyond, p. 39, ABC-CLIO, ISBN 0-313-33868-X</ref> Tatsumi's TX-1 introduced force feedback to car driving games in 1983.<ref name=TX-1>Template:KLOV game</ref> The game Earthshaker! added haptic feedback to a pinball machine in 1989.

Simple haptic devices are common in the form of game controllers, joysticks, and steering wheels. Early implementations were provided through optional components, such as the Nintendo 64 controller's Rumble Pak in 1997. In the same year, the Microsoft SideWinder Force Feedback Pro with built-in feedback was released by Immersion Corporation.<ref>"Microsoft and Immersion Continue Joint Efforts To Advance Future Development of Force Feedback Technology". Stories. 3 February 1998.</ref> Many console controllers and joysticks feature built-in feedback devices, which are motors with unbalanced weights that spin, causing it to vibrate, including Sony's DualShock technology and Microsoft's Impulse Trigger technology. Some automobile steering wheel controllers, for example, are programmed to provide a "feel" of the road. As the user makes a turn or accelerates, the steering wheel responds by resisting turns or slipping out of control.
