ELECTRONIC DEVICE WITH FUNCTION OF RECOGNIZING MULTI-TOUCH INPUTS AND METHOD THEREOF
First Claim
1. An electronic device with a function of recognizing multi-touch inputs, comprising:
- a multi-touch display unit;
an input unit to receive multi-touch inputs on the multi-touch display unit, wherein each multi-touch input comprises a plurality of touch points which forms a touch area;
a storage unit to store a table which records a relationship between an area of the touch area of the multi-touch input and a function of the electronic device; and
a processing unit to sense whether there is a multi-touch input on the display unit, compute the area of the touch area of the multi-touch input when there is a multi-touch input on the multi-touch display unit, and execute a function associated with the computed area in the table stored in the storage unit.

Abstract
An electronic device with a function of recognizing multi-touch inputs includes a multi-touch display unit, an input unit receiving multi-touch inputs on the multi-touch display unit, a storage unit, and a processing unit. Each multi-touch input includes a plurality of touch points which forms a touch area. The storage unit stores a table which records a relationship between an area of the touch area of the multi-touch input and a function of the electronic device. The processing unit senses whether there is a multi-touch input on the display unit, computes the area of the touch area of the multi-touch input when there is a multi-touch input on the multi-touch display unit, and determines a function associated with the computed area in the table stored in the storage unit.

4. A method for recognizing multi-touch inputs implemented by an electronic device, wherein the electronic device comprises a multi-touch display unit, an input unit for receiving multi-touch inputs on the multi-touch display unit, and a storage unit, each multi-touch input comprises a plurality of touch points which forms a touch area, the storage unit is configured to store a table which records a relationship between an area of the touch area of the multi-touch input and a function of the electronic device, the method comprising:
-
sensing whether there is a multi-touch input on the display unit; determining the plurality of touch points of the multi-touch input when there is a multi-touch input on the display unit, and collecting a coordinate value of each touch point; comparing the coordinate values of the plurality of touch points to determine the minimum x and y coordinate values and the maximum x and y coordinate values; computing the area of the touch area of the multi-touch input according to the determined minimum x and y coordinate values and the determined maximum x and y coordinate values; determining a function associated with the determined area in the table stored in the storage unit; and executing a corresponding operation on the electronic device according to the determined function. - View Dependent Claims (5)
