AIREAL: tactile gaming experiences in free air.

ABSTRACTInteractions with our computers have expanded into the physical world. Recent developments of low-cost gesture tracking technologies, like the Microsoft Kinect, have enabled millions of users to interact with their computers by gesturing with their bodies. Furthermore, computer vision tracking and registration techniques now enable novel projection based displays to overlay projected images into our physical environments, creating entirely new augmented reality experiences. These natural interfaces will continue to be incorporated into our mobile devices enabling rich interactive experiences anywhere and at anytime. However, one missing piece to this emerging world of natural interfaces is the absence of physical feedback.
