&quot;Use it inside&quot; doesn&#x27;t completely solve it, at least if you have windows inside.<p>During my master internship at INRIA, a coworker had to put a tablecloth on his desk to be able to get a proper depth image with a Kinect. It turned out to be a small window, 5 meters away, reflecting on his desk. Indirect sun light was enough to mess up the projected pattern.<p>So &quot;Use it in a cave&quot; can be a solution, but it&#x27;s... less attractive.<p>Funny fact is, Hololens doesn&#x27;t work with windows.
