{{AR/VR}}

'''[[Spatial computing]]''' is a term describing the paradigm where [[human-computer interaction]] (HCI) moves beyond traditional desktop or mobile screens, allowing digital information and processes to be perceived and manipulated as if they exist within [[3D space|three-dimensional physical space]].<ref name="GreenwoldThesis">Greenwold, Simon A. "Spatial Computing". MIT Master's Thesis, June 2003. [https://dspace.mit.edu/handle/1721.1/87460 Link]</ref> It involves machines understanding and interacting with the geometry and semantics of the surrounding environment, enabling users to interact with digital content using natural modalities like gestures, gaze, and voice, often overlaying this content onto their view of the real world. In essence, spatial computing extends technologies like [[virtual reality]] (VR), [[augmented reality]] (AR), and [[mixed reality]] (MR) by anchoring digital content to real-world locations and objects, so that virtual elements can be perceived as part of the surrounding environment<ref name="TechTargetWhatIs">Alexander Gillis & George Lawton (Feb 2024). "What is spatial computing?" TechTarget. ("Companies including Apple, Google, Magic Leap, Meta and Microsoft offer spatial computing devices for consumer audiences.")</ref>, collectively sometimes referred to as [[Extended Reality]] (XR). This approach allows users to intuitively manipulate virtual objects as if they were real, and lets computers understand and respond to the user’s physical context, aiming to make the computer interface invisible by leveraging innate 3D human senses and movements.<ref name="PCMagWhatIs">Jessie Will (June 6, 2023). "What Is Spatial Computing? Apple Vision Pro and the Next Wave of Tech." PCMag. (Describes spatial computing as blending digital/physical, using natural inputs)</ref>

In the early 1990s, researchers at the University of Washington’s Human Interface Technology Lab (HIT Lab), led by VR pioneer [[Thomas A. Furness III]], explored advanced 3D interfaces. A spin-off company, Worldesign Inc., founded by Dr. Robert Jacobson, used "Spatial Computing" to describe human interaction within immersive 3D environments at room scale, demonstrating concepts like a virtual Giza Plateau reconstruction in 1993.<ref name="HandwikiHistory"/><ref name="VentureBeatJacobson">Dean Takahashi (June 2023). "With Vision Pro launched, companies must talk about XR, nausea and gender." VentureBeat. (“…‘spatial computing’ — a term that was actually coined in the early 90s by Dr. Bob Jacobson, founder of Worldesign…”)​</ref> An academic publication "Spatial Computing: Issues in Vision, Multimedia and Visualization Technologies" (1997) by T. Caelli and H. Bunke further introduced the term academically.<ref name="HandwikiHistory"/>

The term gained significant traction following [[Simon Greenwold]]'s 2003 Master's thesis at the [[MIT Media Lab]].<ref name="GreenwoldThesis"/> Greenwold defined it as "human interaction with a machine in which the machine retains and manipulates referents to real objects and spaces," emphasizing machines becoming "fuller partners in our work and play."<ref name="TechTargetGreenwoldQuote">Simon Greenwold (June 2003). Spatial Computing (Master’s thesis, MIT Media Arts & Sciences) – as quoted in TechTarget, Feb 2024.</ref> This coincided with growing research in [[context-aware computing]] and ambient interfaces.

*  [[Microsoft HoloLens]] (announced 2015, shipped 2016) was a landmark self-contained "mixed reality" headset performing real-time spatial mapping and anchoring holograms to the environment, described by Microsoft as the first untethered holographic computer.<ref>Microsoft. (2016). "HoloLens: Mixed Reality." Retrieved from https://www.microsoft.com/en-us/hololens</ref>

*  [[Magic Leap]], founded in 2011, heavily marketed the term "Spatial Computing" alongside its [[Magic Leap One]] headset release in 2018, aiming to blend digital lightfield objects with real space.<ref>Magic Leap. (2018). "Magic Leap One Creator Edition." Retrieved from https://www.magicleap.com/en-us</ref>

*  Apple's [[ARKit]] and Google's [[ARCore]] frameworks (2017) brought basic spatial computing (plane detection, tracking) to smartphones, popularizing mobile AR experiences like [[Pokémon GO]].<ref>Niantic. (2016). "Pokémon GO." Retrieved from https://www.pokemongo.com/</ref>

*  Room-scale VR systems (HTC Vive, Oculus Rift) and later standalone headsets ([[Meta Quest|Oculus Quest]], 2019) incorporated inside-out spatial tracking (SLAM) for environmental awareness.

The early 2020s saw further mainstreaming. Facebook rebranded to [[Meta Platforms|Meta]] in 2021, signaling focus on the [[metaverse]], heavily reliant on spatial technologies. A pivotal moment was Apple's unveiling of the [[Apple Vision Pro]] in June 2023, explicitly branding it as a "spatial computer."<ref name="VisionProAnnounce">Apple Newsroom.

*  '''Machine Perception of Space:''' Devices must understand the physical environment in 3D. This involves technologies like [[Simultaneous Localization and Mapping]] (SLAM) to track the device's position and orientation while building a map of the space.<ref>Durrant-Whyte, H., & Bailey, T. (2006). "Simultaneous localization and mapping: Part I." *IEEE Robotics & Automation Magazine*, 13(2), 99-110. doi:10.1109/MRA.2006.1638022</ref> [[Depth sensor]]s (like [[LiDAR]] or Time-of-Flight cameras) and [[RGB camera]]s capture geometric and visual information. [[Computer vision]] algorithms, often powered by [[artificial intelligence]] (AI), interpret this data to recognize surfaces, objects (e.g., walls, tables, chairs), people, and potentially understand scene semantics.<ref name="CogentSLAM">Cogent Infotech (Jan 1, 2025).

*  '''[[Context-aware computing]]:''' Systems that adapt based on current context (location, time, user activity). Spatial computing is inherently context-aware, focusing specifically on real-time ''spatial'' context (geometry, pose, environment).

Numerous startups focus on specific applications or hardware components.

*  '''Technical Limitations:''' Constraints remain in [[Field of view (computer vision)|field of view]] (especially for optical see-through AR), display resolution and brightness, device weight and [[Ergonomics|ergonomic]] comfort, [[Battery life]], and the significant on-device processing power required.<ref>Azuma, R.

Cambridge University Press.</ref> Social acceptance of wearing head-mounted devices in public is still evolving.

*  '''[[Data privacy|Privacy]] and Security:''' Devices constantly scanning the user's environment with cameras and sensors (potentially including [[eye tracking]] and hand tracking) raise significant privacy concerns regarding data collection, storage, and use.<ref name="SpatialPrivacy">Example: "The Privacy Implications of Spatial Computing", Electronic Frontier Foundation, [Date and URL needed]</ref> Robust security measures and clear data policies are needed.

*  '''Definition Ambiguity / Buzzword Status:''' The term "spatial computing" itself has been criticized for being vague or an overused [[buzzword]], particularly following marketing pushes by companies like Apple.<ref name="WaPoAmbiguity">Shira Ovide (Feb 2, 2024). "Apple’s Vision Pro is ‘spatial computing.’ Nobody knows what it means." The Washington Post. (“One problem: No one agrees on the definition of spatial computing.
