Augmented reality has never been nearly as cool as its name suggests. Even when it isn't gimmicky, it's virtually useless, in large part because your mobile camera's version of "reality" is short one dimension. Scanning and computer vision company Occipital, however, wants to add real depth to your tablet's vision with the Structure Sensor, a Kickstarter- backed product that shipped to backers late last year. The $349 Structure Sensor is a Kinect-like camera that fits on the back of an iPad or, with some hacking, any other device. With the bracket on, your tablet doesn't just see objects, it can figure out how far away they are, doing anything from turning an object into a 3D model to measuring the distance of a room.
