Powerless signal generation for use in conjunction with a powerless position determination device

A reflector and a powerless signal generator mechanism are incorporated into a single powerless pointing device. A light source generates a light signal, and the reflector incorporated within the powerless pointing device reflects the light signal back to a image collection system of a computer. Ima...

description A reflector and a powerless signal generator mechanism are incorporated into a single powerless pointing device. A light source generates a light signal, and the reflector incorporated within the powerless pointing device reflects the light signal back to a image collection system of a computer. Image data is generated, and is used to generate position data relating to the position of the reflector. The position is correlated to a position on a graphical user interface. A user action activates the powerless signal generator mechanism, generating a signal. The signal can be, for example, in the form of a sound pulse having one or more predetermined frequencies or an RF signal generated by a piezo-electric transducer.
