Claim:
An input, device for controlling a presentation program that is being run on a remote computing device, the presentation program including at least a first slide and a second slide, the input device comprising: a plurality of optical sensors configured to be activated by exposure to a focused beam of light and configured to generate one or more signals upon exposure to the focused beam of light, the focused beam of light originating from a source independent of the input device; a processing unit configured to receive the signals and produce an instructional signal containing an instruction for changing a displayed slide of the presentation program from the first slide to the second slide; and an RF communication device configured to wirelessly deliver the instructional signal to the remote computing device, wherein each optical sensor is spaced apart from each of the other optical sensors so that the focused beam of light can be directed to one of the plurality of optical sensors without activating an adjacent optical sensor; and wherein the input device is selectively mountable at any location adjacent a display output such that the input device is located within a line-of-sight of a presenter.
