''' Ubiquitous computing''' (or "'''ubicomp'''") is a concept in [[software engineering]], [[hardware engineering]] and [[computer science]] where [[computing]] is made to appear seamlessly anytime and everywhere. In contrast to [[desktop computing]], [[ubiquitous]] computing implies use on any device, in any location, and in any format. A user interacts with the computer, which can exist in many different forms, including [[laptop computers]], [[Tablet computer|tablets]], [[smart phones]] and [[Computer terminal|terminals]] in everyday objects such as a [[refrigerator]] or [[Smartglasses|a pair of glasses]]. The underlying technologies to support ubiquitous computing include the [[Internet]], advanced [[middleware]], [[Kernel (operating system)|kernels]], [[operating system]]s, [[mobile code]]s, [[sensor]]s, [[microprocessor]]s, new [[I/O]]s and [[user interface]]s, [[computer network]]s, mobile protocols, [[GNSS|global navigational system]]s, and new materials.

This [[paradigm]] is also described as '''pervasive computing''',<ref name="Nieuwdorp2007-Discourse">{{Cite journal|last1=Nieuwdorp |first1=E. |title=The pervasive discourse |doi=10.1145/1279540.1279553 |journal=Computers in Entertainment |volume=5 |issue=2 |page=13 |year=2007|s2cid=17759896 }}</ref> [[ambient intelligence]],<ref>{{cite book|title=Pervasive Computing: The Mobile World |last=Hansmann | first=Uwe |year=2003 |publisher=Springer |isbn=978-3-540-00218-5}}</ref> or "everyware".<ref>{{cite book|title=Everyware: The Dawning Age of Ubiquitous Computing |last=Greenfield |first=Adam |author-link=Adam Greenfield |year=2006 |publisher=New Riders |isbn=978-0-321-38401-0 |pages=11–12}}</ref> Each term emphasizes slightly different aspects.

Rather than propose a single definition for ubiquitous computing and for these related terms, a [[Taxonomy (general)|taxonomy]] of properties for ubiquitous computing has been proposed, from which different kinds or flavors of ubiquitous systems and applications can be described.<ref name="Poslad">{{cite book |last=Poslad |first=Stefan |title=Ubiquitous Computing Smart Devices, Smart Environments and Smart Interaction |publisher=Wiley |year=2009 |isbn=978-0-470-03560-3 |url=http://pervasivecomputing.se/M7012E_2014/material/Wiley.Ubiquitous.Computing.Smart.Devices.Environments.And.Interactions.May.2009.eBook.pdf |access-date=2019-05-27 |archive-date=2019-05-27 |archive-url=https://web.archive.org/web/20190527073110/http://pervasivecomputing.se/M7012E_2014/material/Wiley.Ubiquitous.Computing.Smart.Devices.Environments.And.Interactions.May.2009.eBook.pdf |url-status=live }}</ref>

Ubiquitous computing themes include: [[distributed computing]], [[mobile computing]], location computing, mobile networking, [[sensor network]]s, [[human–computer interaction]], [[context awareness|context-aware]] smart home technologies, and [[artificial intelligence]].

== Core concepts ==
Ubiquitous computing is the concept of using small internet connected and inexpensive computers to help with everyday functions in an automated fashion.<ref>{{Cite journal |first=Byeong-Ho |last=Kang|url=https://www.researchgate.net/publication/242615603|title=Ubiquitous Computing Environment Threats and Defensive Measures|journal=International Journal of Multimedia and Ubiquitous Engineering |volume=2 |issue=1 |pages=47–60 |date=January 2007|language=en|access-date=2019-03-22}}</ref>

[[Mark Weiser]] proposed three basic forms for [[smart device|ubiquitous computing devices]]:<ref name="Weiser91" />
*''Tabs'': a wearable device that is approximately a [[centimeter]] in size
*''Pads'': a hand-held device that is approximately a [[decimeter]] in size
*''Boards'': an interactive larger display device that is approximately a [[meter]] in size
Ubiquitous computing devices proposed by Mark Weiser are all based around flat devices of different sizes with a visual display.<ref>{{cite web |url= https://www.karlstechnology.com/blog/some-computer-science-issues-in-ubiquitous-computing/ |title= Some Computer Science Issues in Ubiquitous Computing |publisher= CACM |last= Weiser |first= Mark |date= March 23, 1993 |access-date= May 28, 2019 |archive-date= May 28, 2019 |archive-url= https://web.archive.org/web/20190528015405/https://www.karlstechnology.com/blog/some-computer-science-issues-in-ubiquitous-computing/ |url-status= live }}</ref> Expanding beyond those concepts there is a large array of other ubiquitous computing devices that could exist.<ref name="Poslad" />

== History ==
Mark Weiser coined the phrase "ubiquitous computing" around 1988, during his tenure as Chief Technologist of the [[Xerox PARC|Xerox Palo Alto Research Center (PARC)]]. Both alone and with PARC Director and Chief Scientist [[John Seely Brown]], Weiser wrote some of the earliest papers on the subject, largely defining it and sketching out its major concerns.<ref name="Weiser91">{{cite web|url=https://www.ubiq.com/hypertext/weiser/SciAmDraft3.html |archive-url=https://web.archive.org/web/20141022035044/http://www.ubiq.com/hypertext/weiser/SciAmDraft3.html |title=The Computer for the 21st Century |year=1991 |last=Weiser |first=Mark |author-link=Mark Weiser |archive-date=22 October 2014 |url-status=dead}}</ref><ref>{{cite web|url=http://www.research.ibm.com/journal/sj/384/weiser.html |title=Ubiquitous computing |date=1999-05-11 |last1=Weiser |first1=M. |last2=Gold |first2=R. |last3=Brown |first3=J.S. |url-status=dead |archive-url=https://web.archive.org/web/20090310225239/http://www.research.ibm.com/journal/sj/384/weiser.html |archive-date=10 March 2009}}</ref><ref name="Weiser96">{{cite web|url=http://www.ubiq.com/hypertext/weiser/UbiHome.html |title=Ubiquitous computing |date=17 March 1996 |last=Weiser |first=Mark |author-link=Mark Weiser |url-status=dead |archive-url=https://web.archive.org/web/20180602090007/http://www.ubiq.com/hypertext/weiser/UbiHome.html |archive-date=2 June 2018}}</ref>

== Recognizing the effects of extending processing power ==
Recognizing that the extension of processing power into everyday scenarios would necessitate understandings of social, cultural and psychological phenomena beyond its proper ambit, Weiser was influenced by many fields outside computer science, including "[[philosophy]], [[Phenomenology (philosophy)|phenomenology]], [[anthropology]], [[psychology]], [[post-Modernism]], [[sociology of science]] and [[feminist criticism]]". He was explicit about "the humanistic origins of the 'invisible ideal in post-modernist thought'",<ref name="Weiser96" /> referencing as well the ironically [[dystopia]]n [[Philip K. Dick]] novel ''[[Ubik]]''.

[[Andy Hopper]] from Cambridge University UK proposed and demonstrated the concept of "Teleporting" – where applications follow the user wherever he/she moves.

Roy Want, while a researcher and student working under Andy Hopper at Cambridge University, worked on the "Active Badge System", which is an advanced location computing system where personal mobility that is merged with computing.

Bill Schilit (now at Google) also did some earlier work in this topic, and participated in the early Mobile Computing workshop held in Santa Cruz in 1996.

[[Ken Sakamura]] of the [[University of Tokyo]], [[Japan]] leads the Ubiquitous Networking Laboratory (UNL), [[Tokyo]] as well as the [[T-Engine Forum]]. The joint goal of Sakamura's Ubiquitous Networking specification and the T-Engine forum, is to enable any everyday device to broadcast and receive information.<ref>{{Cite journal|journal=IEEE Pervasive Computing |volume=4 |issue=2 |pages=4–9 |doi=10.1109/MPRV.2005.40 |year=2005 |last1=Krikke |first1=J|title=T-Engine: Japan's ubiquitous computing architecture is ready for prime time |s2cid=11365911 }}</ref><ref>{{cite web |url=http://www.t-engine.org/forum-guide/t-engine-summary |title=T-Engine Forum Summary |publisher=T-engine.org |archive-url=https://web.archive.org/web/20181021030140/http://www.t-engine.org/forum-guide/t-engine-summary |archive-date=21 October 2018 |url-status=dead |access-date=25 August 2011 }}</ref>

== Examples ==
One of the earliest ubiquitous systems was artist [[Natalie Jeremijenko]]'s "Live Wire", also known as "Dangling String", installed at Xerox PARC during Mark Weiser's time there.<ref>{{cite web |url=https://www.karlstechnology.com/blog/designing-calm-technology/ |title=Designing Calm Technology |last=Weiser |first=Mark |date=2017-05-03 |access-date=May 27, 2019 |archive-date=2023-03-06 |archive-url=https://web.archive.org/web/20230306211442/https://www.karlstechnology.com/blog/designing-calm-technology/ |url-status=live }}</ref> This was a piece of string attached to a [[stepper motor]] and controlled by a [[LAN]] connection; network activity caused the string to twitch, yielding a ''peripherally noticeable'' indication of traffic. Weiser called this an example of ''[[calm technology]]''.<ref>{{cite journal|last1=Weiser |first1=Mark |author-link=Mark Weiser |last2=Gold |first2=Rich |last3=Brown |first3=John Seely |author-link3=John Seely Brown |title=The Origins of Ubiquitous Computing Research at PARC in the Late 1980s |year=1999 |journal=IBM Systems Journal |volume=38 |issue=4 |doi=10.1147/sj.384.0693 |page=693|s2cid=38805890 }}</ref>

A present manifestation of this trend is the widespread diffusion of mobile phones. Many mobile phones support high speed data transmission, video services, and other services with powerful computational ability. Although these mobile devices are not necessarily manifestations of ubiquitous computing, there are examples, such as Japan's Yaoyorozu ("Eight Million Gods") Project in which mobile devices, coupled with radio frequency identification tags demonstrate that ubiquitous computing is already present in some form.<ref name="ReferenceA">{{cite journal|last1=Winter |first1=Jenifer |title=Emerging Policy Problems Related to Ubiquitous Computing: Negotiating Stakeholders' Visions of the Future |journal=Knowledge, Technology & Policy|date=December 2008 |volume=21 |issue=4 |pages=191–203 |doi=10.1007/s12130-008-9058-4|hdl=10125/63534 |s2cid=109339320 |hdl-access=free }}</ref>

[[Ambient Devices]] has produced an "orb", a "dashboard", and a "[[weather beacon]]": these decorative devices receive data from a [[wireless network]] and report current events, such as stock prices and the weather, like the [[Nabaztag]], which was invented by [[Rafi Haladjian]] and [[Olivier Mével]], and manufactured by the company Violet.

The Australian futurist [[Mark Pesce]] has produced a highly configurable 52-[[LED]] [[LAMP (software bundle)|LAMP]] enabled lamp which uses [[Wi-Fi]] named ''MooresCloud'' after [[Gordon Moore]].<ref>{{cite web |last=Fingas |first=Jon |url=https://www.engadget.com/2012/10/13/moorescloud-light-runs-linux-puts-lamp-on-your-lamp/ |title=MooresCloud Light runs Linux, puts LAMP on your lamp (video) |publisher=Engadget.com |date=13 October 2012 |access-date=22 March 2019 |archive-date=25 March 2019 |archive-url=https://web.archive.org/web/20190325124949/https://www.engadget.com/2012/10/13/moorescloud-light-runs-linux-puts-lamp-on-your-lamp/ |url-status=live }}</ref>

The [[Unified Computer Intelligence Corporation]] launched a device called ''[[Ubi – The Ubiquitous Computer]]'' designed to allow voice interaction with the home and provide constant access to information.<ref>{{cite web|url=http://www.theubi.com |title=Ubi Cloud |publisher=Theubi.com |url-status=dead |archive-url=https://web.archive.org/web/20150102105946/http://www.theubi.com/ |archive-date=2 January 2015}}</ref>

Ubiquitous computing research has focused on building an environment in which computers allow humans to focus attention on select aspects of the environment and operate in supervisory and policy-making roles. Ubiquitous computing emphasizes the creation of a human computer interface that can interpret and support a user's intentions. For example, MIT's Project Oxygen seeks to create a system in which computation is as pervasive as air:
<blockquote>In the future, computation will be human centered. It will be freely available everywhere, like batteries and power sockets, or oxygen in the air we breathe...We will not need to carry our own devices around with us. Instead, configurable generic devices, either handheld or embedded in the environment, will bring computation to us, whenever we need it and wherever we might be. As we interact with these "anonymous" devices, they will adopt our information personalities. They will respect our desires for privacy and security. We won't have to type, click, or learn new computer jargon. Instead, we'll communicate naturally, using speech and gestures that describe our intent...<ref>{{cite web|url=http://oxygen.csail.mit.edu/Overview.html|title=MIT Project Oxygen: Overview|archive-url=https://web.archive.org/web/20040705165822/http://oxygen.csail.mit.edu/Overview.html|archive-date=July 5, 2004}}</ref></blockquote>

This is a fundamental transition that does not seek to escape the physical world and "enter some metallic, gigabyte-infested cyberspace" but rather brings computers and communications to us, making them "synonymous with the useful tasks they perform".<ref name="ReferenceA" />

[[Network robot]]s link ubiquitous networks with [[robot]]s, contributing to the creation of new lifestyles and solutions to address a variety of social problems including the aging of population and nursing care.<ref>{{cite web|url=http://www.scat.or.jp/nrf/English/index.html |title=Network Robot Forum |url-status=dead |archive-url=https://web.archive.org/web/20071024203219/http://www.scat.or.jp/nrf/English/index.html |archive-date=October 24, 2007}}</ref>
