Abstract

A touch control type character input method is to utilize a control module for identifying moving loci created by an object moving on a hand writing board so as to be used during subsequent input. A plurality of vectors, which move in different directions, are combined and a parameter data collection is defined in the control module. When the object contacts the hand writing board, the position of the hand writing board being first touched is detected and assigned as the initial position. Then, a moving locus generated on the hand writing board is determined if it is effective and the moving locus is disassembled as at least a moving vector in case of being effective and is removed in case of being ineffective. The obtained moving vectors are combined and analyzed and compared with the parameter data collection defined in the control module. A compared result is output if the combined moving vectors are in accordance with the parameter data collection

Claims

1. A touch control type character input method, which has a control module to identify a plurality of moving loci created by an object moving on a hand writing board and to generate a control signal corresponding to a combination of different ones of the moving loci for being used by a host unit performing subsequent input, comprising following steps:

A) combining a plurality of moving vectors in different directions and a parameter data collection available for comparison being defined in the control module;

B) detecting a position, which is touched by the object at the first time on the hand writing board, and assigning the position as an initial position;

C) determining if a moving locus created on the hand writing board is effective and disassembling the moving locus as at east one of the moving vectors in case of the moving locus being effective and removing the moving locus in case of the moving locus being ineffective;

D) combining the moving vectors obtained in step (C) and processing step (E) after the object detaches the hand writing board a period of time duration; and

E) analyzing the obtained and combined moving vectors, comparing the arranged moving vectors with the parameter data collection defined in the control module and outputting a compared result in case of the combined moving vectors being in accordance with the parameter data collection.

2. The touch control type character input method as defined in claim 2, wherein a way for determining if the a moving locus created on the hand writing board is effective in step C) is the moving locus being within a specific angular range with respect to the initial position, which is taken as a rotational center of the angular range.

3. The touch control type character input method as defined in claim 2, wherein the angular range is between 15°

to 60°

.

4. The touch control type character input method as defined in claim 2, wherein a displacement, which is caused by the object moving on the hand writing board, being detected and determined as effective if the displacement exceeds a preset distance is processed in step C.
