Remember Project Tango? Google's 3D-sensing smartphone project started development three years ago and first became public in 2014. The goal was to equip a smartphone with a depth sensor and other computer vision abilities. Why? To see what developers could come up with. It's a bit like strapping an Xbox Kinect to the back of a smartphone.
Now, Tango is finally out in a consumer device, but this is not the triumphant launch of a new flagship product. After years of buildup, Tango is quietly debuting on a mid-range Lenovo phone, the Phab 2 Pro. The bloated, ugly hardware Lenovo created for the Phab 2 feels more like a barely designed developer kit than a slick consumer product.
