US 8,896,551 B2 · System and method for improving recognition of a touch keyboard of an electronic device

Abstract

A system and a method for improving recognition of a touch keyboard in an electronic device include setting a fuzzy set corresponding to each virtual key of the touch keyboard displayed on a touch panel. The improving method further includes receiving coordinates of a touch point on the touch panel, confirming a touched virtual key corresponding to the touched coordinates and executing a function of the touched virtual key. The improving method further confirming one or more adjacent virtual keys of the touched virtual key, and revising a fuzzy set of the received virtual key or a fuzzy set of an adjacent virtual key, if a backspace virtual key and the adjacent virtual key have been touched in turn after the touched virtual key.

Dependent claims

An electronic device, comprising:

a storage system;
a touch panel;
at least one processor;
one or more programs that are stored in the storage system and are executed by the at least one processor, the one or more programs comprising:
a definition module that defines and stores a fuzzy set corresponding to each virtual key of a touch keyboard displayed on the touch panel, wherein the fuzzy set corresponding to each virtual key defines a plurality of membership functions of each virtual key;
a receiving module that receives coordinates of a touch point on the touch panel;
a confirmation module that confirms at least one membership function in the fuzzy set according to the received coordinates for obtaining at least one non-zero membership value, confirms a virtual key corresponding to the received coordinates according to fuzzy sets of virtual keys of the touch keyboard, and determines the virtual key as a touched virtual key and the received coordinates as touched coordinates, wherein the virtual key is confirmed by the one non-zero membership function value from the plurality of the fuzzy sets according to the received coordinates when a number of the at least one non-zero membership function value is one, and the virtual key is confirmed by the larger non-zero membership function value in the two non-zero membership function values when the number of the at least one non-zero membership function value is two;
a processing module that executes a function corresponding to the touched virtual key on the virtual keyboard;
the confirmation module further confirms one or more adjacent virtual keys of the touched virtual key, after the function of the touched virtual key is executed;
the processing module further revises a fuzzy set of the touched virtual key or a fuzzy set of one of the adjacent virtual keys, upon the condition that a backspace virtual key of the touch keyboard and the adjacent virtual key have been touched in turn after the touched virtual key.

executing a function corresponding to the touched virtual key on the virtual keyboard;
confirming one or more adjacent virtual keys of the touched virtual key, after the function of the touched virtual key is executed;
revising a fuzzy set of the touched virtual key or a fuzzy set of one of the adjacent virtual keys, upon the condition that a backspace virtual key and the adjacent virtual key have been touched in turn after the touched virtual key.

confirming at least one membership function in the fuzzy set according to the received coordinates for obtaining at least one non-zero membership value, and confirming a virtual key corresponding to the received coordinates according to fuzzy sets of virtual keys of the touch keyboard, determining the virtual key as a touched virtual key and the received coordinates as touched coordinates, wherein the virtual key is confirmed by the one non-zero membership function value from the plurality of the fuzzy sets according to the received coordinates when a number of the at least one non-zero membership function value is one, and the virtual key is confirmed by the larger non-zero membership function value in the two non-zero membership function values when the number of the at least one non-zero membership function value is two;
executing a function corresponding to the touched virtual key on the virtual keyboard;
confirming one or more adjacent virtual keys of the touched virtual key, after the function of the touched virtual key is executed;
revising a fuzzy set of the touched virtual key or a fuzzy set of one of the adjacent virtual keys, upon the condition that a backspace virtual key and the adjacent virtual key have been touched in turn after the touched virtual key.
