'''확장현실'''(擴張現實, {{llang|en|extended reality}}, '''XR''')은 [[증강 현실]](AR), [[가상 현실]](VR) 및 [[혼합 현실]](MR)을 가리키는 포괄적인 용어다. 이 기술은 물리적 세계와 상호 작용할 수 있는 "디지털 트윈 세계"를 결합하거나 미러링하기 위한 것이다.<ref>{{저널 인용|제목=TwinXR: Method for using digital twin descriptions in industrial eXtended reality applications|저널=Frontiers in Virtual Reality|성=Tu|이름=Xinyi|날짜=2023|권=4|언어=en|doi=10.3389/frvir.2023.1019080|issn=2673-4192}}</ref><ref>{{저널 인용|제목=Extended Reality for Smart Building Operation and Maintenance: A Review|저널=Energies|성=Casini|이름=Marco|날짜=2022|권=15|호=10|쪽=3785|언어=en|doi=10.3390/en15103785|issn=1996-1073}}</ref>

가상 현실과 증강 현실 분야는 빠르게 성장하고 있으며 엔터테인먼트, 마케팅, 부동산, 교육, [[재택근무]] 등 다양한 분야에 적용되고 있다.<ref>{{저널 인용|제목=Why and Who Will Adopt Extended Reality Technology?

== 다감각 확장 현실 ==
다감각 확장 현실은 [[시각]], [[청각]], [[후각]], [[미각]] 및 [[몸감각계|촉각]] 을 포함하는 [[오감|전통적인 오감]]을 통합한다. [[지각 (심리학)|지각]]은 신경계를 통과하는 신호를 포함한다. 시각은 눈의 [[망막]]에 닿는 [[빛]]을 포함하고 냄새는 냄새 [[분자]]에 의해 매개되며 청각은 압력파를 포함한다. 다감각 확장 현실의 감각 신호에는 시각, 청각, 후각, [[햅틱 기술|촉각]] 및 환경이 포함된다.<ref>{{웹 인용|url=https://www.radiantvisionsystems.com/blog/creating-full-sensory-experiences-future-ar/vr/mr/xr|제목=Creating Full Sensory Experiences: The Future of AR/VR/MR/XR|웹사이트=Radiant Vision Systems|언어=en|보존url=https://web.archive.org/web/20210414172829/https://www.radiantvisionsystems.com/blog/creating-full-sensory-experiences-future-ar/vr/mr/xr|보존날짜=2021-04-14|url-status=live|확인날짜=2022-03-18}}</ref><ref>{{웹 인용|url=https://www.researchgate.net/publication/357715173|제목=Impact of multisensory extended reality on tourism experience journey|성=Windasari|이름=Nila|날짜=January 1, 2022|보존url=https://web.archive.org/web/20220318205456/https://www.researchgate.net/publication/357715173_Impact_of_multisensory_extended_reality_on_tourism_experience_journey|보존날짜=March 18, 2022|url-status=live|확인날짜=March 18, 2022}}</ref><ref>{{웹 인용|url=https://www.ericsson.com/en/blog/2021/11/welcome-to-xr-immersive-experiences|제목=Welcome to XR and immersive experiences|날짜=2021-11-30|웹사이트=www.ericsson.com|언어=en|보존url=https://web.archive.org/web/20211207084735/https://www.ericsson.com/en/blog/2021/11/welcome-to-xr-immersive-experiences|보존날짜=2021-12-07|url-status=live|확인날짜=2022-03-18}}</ref>
