METHOD FOR AUTHENTICATING CAPACITIVE TOUCH |
摘要 |
There are provided a method for authenticating capacitive touch. The method for authenticating capacitive touch according to the invention is executed through a system interworking with a capacitive touch screen that supports multi-touch, the method comprising, a first step of receiving touch point information for the plurality of touch points recognized as multi-touch through the capacitive touch screen, a second step of reading the touch point information and identifying a specified touch point corresponding to any one specified touch portion fixed and arranged in a previously specified position in design among touch portions of a touch device in which a plurality of capacitively touchable touch portions are arranged according to a previously designed unique geometric relationship, a third step of coordinate-rotating the plurality of touch points or a geometric relationship for the plurality of touch points to match a designed geometric relationship based on a reference point corresponding to the specified touch point, and a fourth step of authenticating whether the coordinate-rotated geometric relationship matches the designed geometric relationship within a tolerance range or identifying the designed geometric relationship matching the coordinate-rotated geometric relationship within a tolerance range among the designed geometric relationships. |

1. A method for authenticating capacitive touch that is executed through a system interworking with a capacitive touch screen that supports multi-touch, the method comprising:
a first step of storing designed geometric relationships for arranging a plurality of touch portions in a unique geometric relationship on a touch device that is to be touched in a capacitive touch screen; a second step of receiving touch point information about a plurality of touch points recognized as multi-touch through the capacitive touch screen; a third step of reading the touch point information and identifying a specified touch point corresponding to any one specified touch portion fixed and arranged in a specified position in design among the plurality of touch portions arranged in the designed geometric relationship on the touch device; a fourth step of coordinate-rotating the plurality of touch points or a geometric relationship for the plurality of touch points to match the designed geometric relationship based on a reference point corresponding to the specified touch point; and a fifth step of authenticating whether the coordinate-rotated geometric relationship matches the stored designed geometric relationship within a tolerance range or identifying a geometric relationship matching the coordinate-rotated geometric relationship within a tolerance range among the stored designed geometric relationships. |
