Abstract
A stylus contains a switch which makes contact in response to slight radial motion of the stylus tip relative to the stylus housing. Means for emitting radiation operates in response to switch closure, thereby emitting a beam of radiation out the tip. The stylus includes an internal power source, such as one or more batteries, for operation of the means for emitting radiation. When such internal power source is capable of being recharged, the stylus may include means for external connection to the recharging supply. In another embodiment, the stylus is capable of emitting more than one type of radiation which are distinguishable, such as by wavelength, modulation type, or other convenient means. In this manner, the stylus can be controlled by the user to emit different signals, which may be interpreted by a receiving device, for example, as different colors, or as a write signal versus an erase signal. In one embodiment, such an erase signal is emitted from the opposite end of the stylus as the write signal.
