Abstract: Techniques for manipulating a three-dimensional scene displayed via a multi-touch display include receiving information associated with an end-user touching a multi-touch display at one or more screen locations, determining a hand movement based on the information associated with the end-user touching the multi-touch display, determining a command associated with the hand movement, and causing the three-dimensional to be manipulated based on the command and the one or more screen locations. The disclosed techniques advantageously provide more intuitive and user-friendly approaches for interacting with a 3D scene displayed on a computing device that includes a multi-touch display.
