Project Tango is a five-inch handset running, surprise surprise, Android. The device uses cameras and depth-perception sensors to constantly map out the holder's physical environment in 3D and match that to the phone's internal gyroscopic systems and more general location data from GPS.
This data can be used by the phone to build up an accurate picture of its surroundings so that software can combine it with on-screen graphics, or throw the information into a database for later use. Imagine walking through a room, the phone in your hand detecting the walls surrounding you, and an app displaying stuff on the screen using that proximity data, for example.
"Mobile devices today assume that the physical world ends at the boundaries of the screen," said ATAP’s technical program leader Johnny Lee. "Our goal is to give mobile devices a human-scale understanding of space and motion."
- For those of you who don't know who Johnny Lee is , he has a series of amazing you tube videos doing 3D movement and projects. What ever he does I am sure it will be amazing.
