Cursor control system
View Patent ↗A method and apparatus for a novel cursor control system is disclosed. In one embodiment, the invention is a method of manipulating a cursor on a tv screen utilizing a wireless remote control. The method includes detecting a location on the screen pointed to by the remote control. The method also includes Transmitting the location to a set-top box.
1. A remote control device comprising:
a housing having an aperture:
a sensor within the housing, coupled to the housing at a location within an optical path from the aperture;
a microcontroller electrically coupled to the sensor and coupled to the housing;
a transmitter electrically coupled to the microcontroller and coupled to the housing;
a semi-mirror coupled to the housing and disposed within the optical path from the aperture between the aperture and the sensor; and
a light source coupled to the housing and disposed in a position relative to the semi-mirror suitable for emitting a light beam targeted at the semi-mirror which, upon reflection by the semi-mirror, follows the optical path from the semi-mirror to the aperture.
2. The remote control device of claim 1 , further comprising:
a first focus element disposed in the optical path between the semi-mirror and the aperture.
3. The remote control device of claim 2 , further comprising:
a second focus element disposed in the optical path between the semi-mirror and the first focus element.
4. The remote control device of claim 3 wherein:
the light source is a laser LED;
the first focus element is a blind; and
the second focus element is a blind.
