System and method for determining input from spatial position of an object

Abstract

A system and method for determining an input is provided. The system includes an object position determination device and an input determination device. The object position determination device is configured to determine a first position of an object at a first time and a second position of the object at a second time. The object position determination device includes a camera configured to detect light traveling from the object to the camera. The input determination device is configured to determine an input based at least partly upon the first position and the second position. The object position determination device can include a second camera. The object can include a radio frequency emitter. The object can include an infrared emitter. The object can be an electronic device.
