Project Tango began three years ago at Google as a small research and development team, but as explained during the press conference, that team has grown much larger as it has helped to create the technology inside the just announced Lenovo PHAB 2 Pro smartphone. Google felt that having "Project" in the name of the group was not inappropriate and decided to shorten it to just Tango from now on.
The Lenovo PHAB 2 Pro will be the first consumer smartphone with Google's Tango technology. It has a 3D camera inside that can sense and map out its surroundings. The phone will be available for sale at Lowe's and Best Buy stores at the end of the summer for $499.
