1. A character input method, applicable to a handheld electronic device, comprising:
- sensing a motion path of the handheld electronic device, which step comprises sensing a plurality of segmental motion paths of the handheld electronic device for constituting the motion path, wherein the step of sensing one of the segmental motion paths comprises;
receiving a start instruction to record information of a start position from which the handheld electronic device moves, and recording the information of the start position;
recording information of a plurality of middle positions of the handheld electronic device away from the start position;
receiving an end instruction to record information of an end position at which the movement of the handheld electronic device ends, and recording the information of the end position; and
determining the one of the segmental motion paths according to the information of the start position, the information of the middle positions, and the information of the end position;
transforming the motion path into a stroke path; and
recognizing an input character corresponding to the stroke path.

6. A handheld electronic device, comprising:
-
a motion sensing unit for sensing a motion path of the handheld electronic device, wherein the motion sensing unit is configured to sense a plurality of segmental motion paths of the handheld electronic device for constituting the motion path; a processing unit for receiving the motion path, transforming the motion path into a stroke path, and recognizing an input character corresponding to the stroke path, wherein in order to sense one of the segmental motion paths, the processing unit is configured to record information of a start position of the handheld electronic device sensed by the motion sensing unit according to a start instruction, record information of a plurality of middle positions of the handheld electronic device sensed by the motion sensing unit and away from the start position, records, according to an end instruction, information of an end position of the handheld electronic device sensed by the motion sensing unit, and determine said one of the segmental motion paths according to the information of the start position, the information of the middle positions, and the information of the end position; and a display unit for receiving and displaying the input character recognized by the processing unit. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
