Some time ago I mentioned the excellent free augmented reality framework from Qualcomm called Vuforia.
Here’s an interesting example from Vivien Cormier called the iOS tangible detector for detecting objects that are placed on the screen. The library does this by detecting the distance between three points on the object, and making calculations about the size, and angle of the object based on the location of those points.
Here’s a video of the Tangible Detector in action:
You can find the iOSTangibleDetector on Github here.
