Abstract
An input device for interfacing with a computing device is provided. The input device includes a body configured to be held within a human hand. The input device includes a light emitting diode (LED) affixed to the body and a power supply for the LED. A mode change activator is integrated into the body, where the mode change activator is configured to cause a change of a color of a light originating from the LED. The color change is capable of being detected to cause a mode change at the computing device. Methods for detecting input commands from an input source within a field of sight of an image capture device, and a computing system which includes the input device are provided.
