Embodiment Construction

[0113] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0114] In related technologies, touch screens have been widely used, and users can perform gesture operations such as clicking, double-clicking, sliding, and long-pressing on the touch screen. The premise of these gesture operations is that they must be in contact with the touch screen. If the user's hands are dirty and it is inconvenient to touch the touch screen, it will be more difficult to realize the above-mentioned gesture operation. Therefore, the industry has proposed the concept of floating gesture operation, but there is no effective solution in the industry on how to realize the floating gesture operation.

[0115] In order to solve the above problems, t...

Abstract

The invention discloses a method and device for gesture model establishment and gesture authentication. The method is used for achieving gesture detection of a suspension gesture and improving the accuracy of detection. The method for gesture model establishment includes the steps of acquiring effective multiple groups of sensing signal strength, wherein each group of sensing signal strength includes the sensing signal strength of all sensing capacitors in a capacitive touch screen; normalizing each group of sensing signal strength; determining a sensing signal variation of the sensing signalstrength between the normalized groups; establishing a gesture model according to the determined sensing signal variation.

Description

technical field [0001] The invention relates to the technical fields of computer and communication, in particular to a method and device for establishing gesture models and authenticating gestures. Background technique [0002] Gesture sensing, also known as touch-free technology, mainly senses and processes the user's operation gestures through various sensors on the mobile phone to complete a series of controls. An important technology to realize gesture sensing is floating touch technology. [0003] The floating touch technology records the user's input on the screen through capacitive touch sensing. Events that occur when the phone screen is touched are called touch events. Capacitive touch works by applying a voltage across a grid of X-Y electrodes covering the phone. When a finger is brought close to the electrodes, the capacitance changes and can be measured. By comparing the measurements of all the electrodes, it is possible to pinpoint exactly where the finger i...
