Editing Haptic technology (section)

== Applications ==

=== Control ===

==== Telepresence ====
Haptic feedback is essential to perform complex tasks via [[telepresence]]. The [[Shadow Hand]], an advanced robotic hand, has a total of 129 touch sensors embedded in every joint and finger pad that relay information to the operator. This allows tasks such as typing to be performed from a distance.<ref>{{cite web |last=Dormehl |first=Luke |date=2019-04-27 |title=The holy grail of robotics: Inside the quest to build a mechanical human hand |url=https://www.digitaltrends.com/cool-tech/shadow-robot-company-hand/ |access-date=2019-07-20 |website=Digital Trends}}</ref> An early prototype can be seen in [[NASA]]'s collection of humanoid robots, or [[robonaut]]s.<ref>{{cite web |title=Robonaut |url=http://robonaut.jsc.nasa.gov/ |access-date=2010-02-26 |publisher=Robonaut.jsc.nasa.gov}}</ref>

==== Teleoperation ====
[[Teleoperation|Teleoperators]] are remote controlled robotic tools. When the operator is given feedback on the forces involved, this is called ''haptic teleoperation''. The first electrically actuated teleoperators were built in the 1950s at the [[Argonne National Laboratory]] by [[Raymond Goertz]] to remotely handle radioactive substances.<ref>{{Cite journal |last=Goertz |first=R.C. |date=1952-11-01 |title=Fundamentals of general purpose remote manipulators |journal=Nucleonics |volume=10 |pages=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 [[simulation|simulators]] and [[flight simulator]]s 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., "[https://www.researchgate.net/profile/Jan_Albiez/publication/259597133_Human_Force_Discrimination_during_Active_Arm_Motion_for_Force_Feedback_Design/links/00b7d52cd8522e50aa000000.pdf 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>

==== Medicine and dentistry ====

==== Automotive ====
With the introduction of large touchscreen control panels in vehicle dashboards, haptic feedback technology is used to provide confirmation of touch commands without needing the driver to take their eyes off the road.<ref>{{cite journal |last1=Breitschaft |first1=Stefan Josef |last2=Clarke |first2=Stella |last3=Carbon |first3=Claus-Christian |title=A Theoretical Framework of Haptic Processing in Automotive User Interfaces and Its Implications on Design and Engineering |journal=Frontiers in Psychology |volume=10 |page=1470 |doi=10.3389/fpsyg.2019.01470 |pmid=31402879 |pmc=6676796 |date=26 July 2019|doi-access=free }}</ref> Additional contact surfaces, for example the steering wheel or seat, can also provide haptic information to the driver, for example, a warning vibration pattern when close to other vehicles.<ref>{{cite web |last1=Kern |first1=Dagmar |last2=Pfleging |first2=Bastian |title=Supporting Interaction Through Haptic Feedback in Automotive User Interfaces |url=https://www.medien.ifi.lmu.de/pubdb/publications/pub/kern2013haptic/kern2013haptic.pdf |publisher=Department for Informatics, University of Munich |access-date=25 October 2019}}</ref>

==== Aviation ====
Force-feedback can be used to increase adherence to a safe [[flight envelope protection|flight envelope]] and thus reduce the risk of pilots entering dangerous states of flights outside the operational borders while maintaining the pilots' final authority and increasing their [[situation awareness]].<ref>{{cite journal |author1=Florian J.

=== Electronic devices ===

==== Video games ====
[[File:Dreamcast-Jump-Pack.jpg|thumb|Rumble packs for controllers, such as this [[Dreamcast]] Jump Pack, provide haptic feedback through users' hands.]]Haptic feedback is commonly used in [[arcade game]]s, especially [[racing video game]]s. In 1976, [[Sega]]'s motorbike game ''[[Fonz (arcade)|Moto-Cross]]'',<ref name="Moto-Cross">{{KLOV game|12812|Moto-Cross}}</ref> also known as ''[[Fonz (arcade)|Fonz]]'',<ref name="Fonz">{{KLOV game|id=12812|name=Fonz}}</ref> was the first game to use haptic feedback, causing the handlebars to vibrate during a collision with another vehicle.<ref name=":3">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">{{KLOV game|id=10004|name=TX-1}}</ref> The game ''[[Earthshaker! (pinball)|Earthshaker!]]'' added haptic feedback to a [[pinball]] machine in 1989.

Simple haptic devices are common in the form of [[game controller]]s, 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|Microsoft SideWinder Force Feedback Pro]] with built-in feedback was released by [[Immersion Corporation]].<ref>{{cite web|url=https://news.microsoft.com/1998/02/03/microsoft-and-immersion-continue-joint-efforts-to-advance-future-development-of-force-feedback-technology/|title=Microsoft and Immersion Continue Joint Efforts To Advance Future Development of Force Feedback Technology|date=3 February 1998|website=Stories}}</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 [[Xbox One Controller|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.

* In 2013, [[Apple Inc.]] was awarded the patent for a haptic feedback system that is suitable for multitouch surfaces. Apple's U.S. Patent for a "Method and apparatus for localization of haptic feedback" describes a system where at least two actuators are positioned beneath a multitouch input device, providing vibratory feedback when a user makes contact with the unit.<ref>{{cite web |author=Pance, Alioshin & Bilbrey, Aleksandar & Paul, Brett |date=February 19, 2013 |title=United States Patent: 8378797 – Method and apparatus for localization of haptic feedback |url=http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=/netahtml/PTO/search-adv.htm&r=33&f=G&l=50&d=PTXT&S1=(apple.ASNM.+AND+20130219.PD.)&OS=an/apple+and+isd/2/19/2013&RS=(AN/apple+AND+ISD/20130219) |access-date=2017-05-17 |issue=8378797 |archive-date=2018-05-13 |archive-url=https://web.archive.org/web/20180513080842/http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=/netahtml/PTO/search-adv.htm&r=33&f=G&l=50&d=PTXT&S1=(apple.ASNM.+AND+20130219.PD.)&OS=an/apple+and+isd/2/19/2013&RS=(AN/apple+AND+ISD/20130219) |url-status=dead }}</ref> Specifically, the patent provides for one actuator to induce a feedback vibration, while at least one other actuator uses its vibrations to localize the haptic experience by preventing the first set of vibrations from propagating to other areas of the device.

==== Tactile electronic displays ====
{{see also|Braille terminal|Braille e-book}}

A tactile electronic display is a [[display device]] that delivers text and graphical information using the sense of touch. Devices of this kind have been developed to assist blind or deaf users by providing an alternative to visual or auditory sensation.<ref>{{Cite journal |last1=Chouvardas |first1=V.G. |last2=Miliou |first2=A.N. |last3=Hatalis |first3=M.K. |date=2008 |title=Tactile displays: Overview and recent advances |url=http://www.nano-micro.gr/papers/Chouvardas_2008_Displays.pdf |journal=Displays |language=en |volume=29 |issue=3 |pages=185–194 |citeseerx=10.1.1.180.3710 |doi=10.1016/j.displa.2007.07.003 |s2cid=16783458}}</ref><ref>{{cite web |title=Here's What the Future of Haptic Technology Looks (Or Rather, Feels) Like |url=https://www.smithsonianmag.com/innovation/heres-what-future-haptic-technology-looks-or-rather-feels-180971097/ |access-date=2019-07-20 |website=Smithsonian |language=en}}</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|date=January 2021}} 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.

=== Neurorehabilitation and balance ===
For individuals with upper limb motor dysfunction, robotic devices utilizing haptic feedback could be used for neurorehabilitation. Robotic devices, such as end-effectors, and both grounded and ungrounded exoskeletons have been designed to assist in restoring control over several muscle groups. Haptic feedback applied by these robotic devices helps in the recovery of sensory function due to its more immersive nature.<ref>Piggott, Leah, Samantha Wagner, and Mounia Ziat.
