The biggest use case for depth sensors on a phone are Augmented Reality applications.<p>We have been playing with a Tango for a while, but quite frankly I was disappointed with it&#x27;s tracking capability compared to what we can achieve with a standard RGB phone camera within our own application.<p>We think we are at the point that we can do 3D reconstruction and ranging as well, and as quickly, with commodity RGB hardware and vSLAM, as you can get from depth cameras in 95% of the environments.
