Embodiment 1

[0085] When the user performs a touch operation on the electronic device, the electronic device uses the signal amplitude value generated by the user's first touch on the screen as a reference signal amplitude value, and stores the reference signal amplitude value.

[0086] In this application, first obtain a threshold value pre-stored in the electronic device and the reference signal amplitude value of each operator, and subtract the signal amplitude value of each touch point among the M touch points obtained from the pre-stored reference signal amplitude value , so as to obtain M difference values ​​between the signal amplitude value and the reference signal amplitude value.

[0087] The pre-stored threshold is a range value determined according to changes in the characteristic information of the human body.

[0088] Further, each of the M difference values ​​is compared with a pre-stored threshold, if there are multiple difference values ​​within the threshold range, then t...

Embodiment 2

[0102] In this application, another embodiment of determining that there are N operators corresponding to M touch points is provided, as follows:

[0103] The electronic device acquires a preset range value, and the preset range value changes according to the capacitance magnitude value caused by the user's continuous touch on the screen of the electronic device.

[0104] After obtaining the preset range value, do two-by-two quotient between the M signal amplitude values, obtain the quotient value after the quotient, compare the quotient value with the preset range value, and return the quotient value within the preset range to for a category.

[0105] Since each quotient value is obtained by doing a quotient between two of the M signal amplitude values, each quotient value corresponds to two signal amplitude values, and after the quotient values ​​are classified into one category, the quotient values ​​correspond to The corresponding signal amplitude values ​​are also classi...

Abstract

The application provides a method and a device for identifying multi-touch information. The method comprises the following steps of detecting whether M touch points for operating a screen are available at the same time or not, wherein M is an integral number which is greater than or equal to 1, obtaining touch information of each touch point in the M touch points when the M touch points are available at the same time, wherein each touch information in M touch information leastways comprises a signal amplitude value used for determining an operator which corresponds to each touch point, processing M signal amplitude amplitudes included in the M touch information, and confirming that the number of operators which correspond to the M touch points is N. Furthermore, the operation can be corresponded to the users by electric equipment when the users operate on the screen of one electric equipment, so that the touch points of the users on the full screen can be distinguished from one another; and therefore, the users on the screen of the electric equipment can be distinguished from one another, the operation of the users can be distinguished from one another, the distinguished touch points can be positioned in a shortage way, and the operation of the users can be responded.

Description

technical field [0001] The present application relates to the field of computer applications, in particular to a method and device for identifying multi-touch information. Background technique [0002] With the continuous improvement of computer technology, there are many types of multi-touch display screens, which can achieve the ability to detect more than 10 contacts at the same time. However, when multiple users operate on a single machine at the same time, the device can only detect the positions of all contacts, and cannot distinguish different operators. Therefore, when multiple users are operating on a single machine at the same time, the operation interface can be processed in different regions to meet the needs of multiple users playing games at the same time. [0003] In the prior art, when multiple touch points appear on the touch screen, the user can only operate in the designated area because the operation interface is divided into areas, and the operation bey...
