First Claim
Patent Images
1. A method for outputting a command by detecting a movement of an object, the method comprising:
- capturing a plurality of images generated by the movement of the object at different timings by an image capturing device;
calculating a motion trajectory according to the images, wherein the motion trajectory includes a rotation; and
outputting the command according to the motion trajectory to control an action of an electronic device;
wherein when the object stops moving, the action of the electronic device is decelerated according to a function of a speed of the object in a time period before the object stops moving; and
wherein one command includes one or more command units, and when the object moves relatively faster, by a motion trajectory, more command units are outputted, while when the object moves relatively slower, by the same motion trajectory, less command unit or units are outputted, whereby different commands are outputted according to different rotation velocities of the movement of the object.

Abstract
The present invention discloses a method for outputting a command by detecting a movement of an object, which includes the following steps. First, an image capturing device captures images generated by the movement of the object at different timings by. Next, a motion trajectory is calculated according to the plurality of images. Further next, a corresponding command is outputted according to the motion trajectory. The present invention also provides a system which employs the above-mentioned method.
