Handheld device with tract input function
First Claim
1. A handheld device with tract input function, the handheld device comprising:
- an optical sensor disposed on the handheld device for detecting the movement of the handheld device to output a displacement signal when the handheld device is set for generating input data according to the movement of the handheld device by a user;
a micro-controller coupled to the optical sensor to generate a tract signal in response to the displacement signal;
an identifier coupled to the micro-controller to selectively identify the tract signal for outputting at least a corresponding symbol according to the tract signal for the user to select as the input data;
a display device disposed on the handheld device and coupled to the micro-controller; and
a memory for storing the input data;
wherein when the handheld device is in a text mode and the whole handheld device is moved in a way corresponding to a desired symbol, the identifier outputs said at least the corresponding symbol and the display device displays said at least the corresponding symbol for the user to select as the input data corresponding to the desired symbol;
whereby the handheld device selectively serves as an input device for the handheld device through the movement of the whole handheld device by the user.

Abstract
A handheld device with tract input function, which allows a user to move the whole handheld device for generating input data for the handheld device itself. The handheld device includes a sensor disposed on the handheld device for detecting the movement of the handheld device to output a displacement signal; a micro-controller coupled to the sensor to generate a tract signal in response to the displacement signal; an identifier coupled to the micro-controller to identify the tract signal for outputting at least a corresponding symbol for the user to select as the input data; a display device disposed on the handheld device; and a memory for storing the input data. The display device displays at least the corresponding symbol for the user to select as the input data corresponding to a desired symbol.
