Abstract
A user input device includes one or more user controls that enable a user to selectively imports bits of data by activating the control when the user input devices proximate to a display surface of an interactive display system. By depressing or otherwise activating a user control, the user causes an element within the user input device to move through a plane of change so that the state of a parameter sensed by the interactive display system changes and is detected. In the examples provided, the parameter relates to infrared light that is reflected or absorbed or produced by a component of the user input device and is thus detected by an infrared sensitive camera. The input can be a single bit, or comprise a plurality of bits corresponding to a specific pattern.
