Abstract
A system having a finger-wearable sleeve having an IR light-emitting diode (LED), an IR camera; and a controller associated with the IR camera. The controller is configured to communicate with a host computer that utilizes a visual content projector to project visual content onto the screen. And based on signals received from the IR camera (1) trigger a first input functionality in the host computer, wherein the first input functionality is based on a location on the screen where an IR beam from the IR laser impinges, and (2) trigger a second input functionality in the host computer, wherein the second input functionality is based on a location on the screen near where an IR beam from the IR LED is emitted.
