Remote input device
First Claim
1. A system for providing an input value to an electronic device, the system comprising:
- a sender portion adapted to be manipulated by a user, the sender portion including a light projecting system adapted to form a projection of an encoded pattern of light with respect to the light projecting system, the projection including a plurality of intensity transitions at a target area; and
a receiver portion including at least one sensor unit, the at least one sensor unit adapted to measure at least one intensity value of the intensity transitions of the projection at a location of the at least one sensor unit, wherein the receiver portion includes logic adapted to determine a position or orientation input value associated with the sender portion from the at least one intensity value of the intensity transitions of the projection at the location of the at least one sensor unit, wherein the receiver portion includes logic that determines a location of the sender portion based at least in part on matching the at least one intensity value to a known or determinable spatial distribution of light intensity.

Abstract
An input device providing users with a pointing capability includes a sender portion (100) and a receiver portion (200). The sender portion (100) is adapted to be manipulated by a user (the user manipulating button 125) to specify a target point within a target area. The sender portion projects a light beam (light output from light source 115) including a pattern onto the target area. A receiver portion (200) includes one or more sensor units (205, 210, 215) located in or near the target area. At least some of the sensor units (205, 210, 215) receive a portion of the light beam (light output from light source 115) regardless of the location of the target point within the target area. A processing unit (220) in the receiver portion (200) analyzes the portions of the light beam received by one or more sensor units (205, 210, 215) to determine an attribute of the target point. The attribute can be the location or relative motion of the target point. The receiver portion (200) may be integrated with a display device.

6. A system for providing a positional input value to an electronic device, the system comprising:
-
a sender portion adapted to be manipulated by a user to specify a target point within a target area, the sender portion including a light projecting system adapted to project a beam of light including an encoded pattern, the beam of light and the encoded pattern forming a projected pattern having a predefined spatially varying characteristic at the target area, the encoded pattern being adapted such that a number of transitions of the encoded pattern is proportional to a magnitude of a relative motion of the target point; and a receiver portion including at least one sensor unit, the sensor unit adapted to measure at least one amount of light of the spatially varying characteristic of the projected pattern at a location of the sensor unit, wherein the receiver portion includes logic adapted to determine a positional input value associated with the target point from the at least one amount of light of the spatially varying characteristic at the location of the sensor unit, wherein the sensor unit is attached to a user-moveable object. - View Dependent Claims (7, 8, 9, 10, 11, 12)
