According to comments by the [[Lighthouse]] developers at conventions and on Twitter<ref>Yates, A. (2015).

Retrieved from https://tsdr.uspto.gov/#caseNumber=86558185&caseType=SERIAL_NO&searchType=statusSearch</ref>, it seems likely that the [[HTC Vive]] will eventually use a stereo pair of cameras or a depth camera to aid in "detection and measurement" the user's surroundings. This might be a one-time calibration, or it could provide constantly updating information to capture changes in the user's environment. Gathering data in this fashion would also likely allow the recognition of furniture and other small objects.
