Image-based control of video games
First Claim
1. A device for controlling a video game, comprising:
- an input having a movable reference surface;
an imager operable to capture images of the reference surface; and
a movement detector operable to detect movement of the reference surface based on one or more comparisons between images of the reference surface captured by the imager and to generate output signals for controlling the video game based on the detected movement.

Abstract
Image-based video game control devices are described. In one aspect, a device for controlling a video game includes an input, an imager, and a movement detector. The input has a movable reference surface. The imager is operable to capture images of the reference surface. The movement detector is operable to detect movement of the reference surface based on one or more comparisons between images of the reference surface captured by the imager and to generate output signals for controlling the video game based on the detected movement. In another aspect, a device for controlling a video game includes a movable input, an imager, and a movement detector. The imager is attached to the input and is operable to capture images of a scene in the vicinity of the input. The movement detector is operable to compute three-dimensional position coordinates for the input based at least in part on one or more comparisons between images of the scene captured by the imager and to generate output signals for controlling the video game based on the computed position coordinates.
