For some years now, the ATAP-Team from Google in cooperation with the manufacturer for chips Nvidia are working together to develop a Smartphone in 3D with three cameras. The smartphone will better understand and recognize the environment.
The smartphone will be able to gather more than 250.000 measured values in a second. The actual smartphones models capture only horizontal motions by user but not up and down.
The project tango is currently in the BETA-Phase. A lot of functions must be checked by developer.
