Abstract
The disclosure is related to a method, a touch device and a computer program product for converting touch points into characters. In particular, through an input interface, the converting method can be applied to the touch device and the computer program product. The converting method for example includes the following steps of: sensing at least one touch point triggered by a user on the input interface to obtain touch point number information and touch point position information; generating a touch point distribution of the sensed touch point(s) according to the touch point number information and the touch point position information; and determining an input character according to the touch point distribution.
Claims16
A method for converting at least one touch point into a character, applied to an input interface of a touch device comprising a processor and a non-transitory computer-readable storage medium, the method comprising:
- sensing the at least one touch point triggered by a user on the input interface to obtain a first touch point number information and a first touch point position information, wherein a touch point corresponds to a discrete single position;
- determining whether the first touch point number information matches with a predetermined touch point number information representative of an input character;
- determining whether the first touch point position information matches with a predetermined touch point position information representative of the input character, wherein the first touch point position information comprises an angle and a distance;
- and
- determining the sensed touch point to be the input character based on a determination that the first touch point number information matches with the predetermined touch point number information representative of the input character and a determination that the first touch point position information matches with the predetermined touch point number information and the predetermined touch point position information representative of the input character;
- wherein, said predetermined touch point number information and said predetermined touch point position information representative of the input character are contained in a lookup table.
A touch device for converting at least one touch point into a character, comprising:
- a recognition unit, for sensing the at least one touch point triggered by a user on an input interface to obtain a first touch point number information and a first touch point position information of the at least one touch point, wherein a touch point corresponds to a discrete single position;
- a control unit, electrically coupled to the recognition unit, for determining whether the first touch point number information matches with a predetermined touch point number information representative of an input character, determining whether the first touch point position information matches with a predetermined touch point position information representative of the input character, and determining the sensed touch point to be the input character based on a determination that the first touch point number information matches with the predetermined touch point number information representative of the input character and a determination that the first touch point position information matches with the predetermined touch point number information and the predetermined touch point position information representative of the input character;
- and
- a storage unit, coupled to the recognition unit and the control unit, for providing a lookup table;
- wherein, said first touch point number information and said first touch point position information representative of the input character are contained in said lookup table, and the first touch point position information comprises an angle and a distance.
A non-transitory computer-readable medium encoded with a computer program, the computer program being executed by an electronic device to convert at least one touch point triggered by a user on an input interface of the electronic device into a character by steps comprising:
- sensing the at least one touch point triggered by a user on the input interface to obtain a first touch point number information and a first touch point position information according to the sensed at least one touch point, wherein a touch point corresponds to a discrete single position;
- determining whether the first touch point number information matches with a predetermined touch point number information representative of an input character;
- determining whether the first touch point position information matches with a predetermined touch point position information representative of the input character, wherein the first touch point position information comprises an angle and a distance;
- and
- determining the sensed touch point to be the input character based on a determination that the first touch point number information matches with the predetermined touch point number information representative of the input character, and a determination that the first touch point position information matches with the predetermined touch point number information and the predetermined touch point position information representative of the input character;
- wherein, said first touch point number information and first said touch point position information representative of the input character are contained in a lookup table.
