The LP4 Handheld Laser Presenter from Califone can identify objects up to 650' away, but with its receiver plugged into a computer's USB port (Mac & Windows compatible), the Presenter can also open an email program, a desktop, or an internet browser, with page up/down capabilities. With the flick of a switch, a second mode adds close, My Computer, and zoom in/out abilities.
