Problems solved by technology

[0002] At present, the gesture recognition functions of smart touch devices such as mobile phones and large-size tablets on the market are very rough. For example, the five-finger grabbing gesture is set in the ipad to close the current application. apps cannot take advantage of the five-finger grab gesture
Another example is a tablet computer, which is set to take screenshots by swiping two fingers horizontally. If the running application itself has set two-finger horizontal swiping to perform fast-forward operations, then when the user makes this gesture, It is impossible to accurately determine whether the user's intention is a screenshot operation or a fast-forward operation
In general, the biggest shortcoming of the current gesture recognition system is that the operating system of the smart touch device and various applications may set different operation instructions for the same gesture, so that the system cannot perform well when the user performs gestures. It is hard to judge the real intention of the user, it is difficult to accurately obtain relevant operation instructions, it is easy to cause misoperation, and the user friendliness is poor

Embodiment 1

[0062] A gesture recognition system comprising:

[0063] The first parsing module is configured to receive a user input instruction and send a broadcast notification of entering gesture recognition mode in response to the fact that the user input instruction matches the first preset instruction;

[0064] The first broadcast processing module is used to draw a transparent signal receiving window on the top layer of the system in response to the broadcast notification of entering the gesture recognition mode;

[0065] The gesture capture module is used to capture the user's operation gesture through the signal receiving window;

[0066] The signal processing module is configured to match the user's operation gesture with the associated pre-stored operation gesture, obtain and execute the operation instruction corresponding to the pre-stored operation gesture that matches the operation gesture;

[0067] The second parsing module is configured to receive a user input instruction ...

Embodiment 2

[0077] refer to figure 1 , a gesture recognition method, comprising:

[0078] S1. Receive a user input command and send a broadcast notification of entering gesture recognition mode in response to the fact that the user input command matches the first preset command;

[0079] S2. In response to the broadcast notification of entering the gesture recognition mode, draw a transparent signal receiving window on the top layer of the system; since the window management system of the operating system is layered, the closer to the top layer, the higher the priority of capturing touch events. Therefore, this embodiment adds a transparent signal receiving window at the top of the system as the first window that receives the touch event, so that the touch event is received through the transparent signal receiving window and the corresponding operation is triggered, and no longer passed to the next a window on the first floor;

[0080] S3. Capturing the user's operation gesture through ...

Abstract

The invention discloses a gesture identification system and method. The method comprises the steps of receiving a user input instruction and sending a broadcast notice of entering a gesture identification mode in response to a situation of matching between the user input instruction and a first preset instruction; drawing a transparent signal receiving window at a top layer of a system; capturing an operation gesture of a user through the signal receiving window; after the operation gesture of the user is matched with an associated pre-stored operation gesture, obtaining an operation instruction corresponding to the pre-stored operation gesture matched with the operation gesture and executing the operation instruction; receiving the user input instruction and sending a broadcast notice of exiting from the gesture identification mode in response to a situation of matching between the user input instruction and a second preset instruction; and deleting the signal receiving window. According to the system and method, the operation instruction corresponding to the operation gesture of the user can be well judged and obtained and is executed; the misoperation is not caused; and the system and method are high in accuracy of identification and high in user friendliness, and can be widely applied to the control industry of smart devices.

Description

technical field [0001] The present invention relates to the field of touch control of smart devices, in particular to a gesture recognition system and method. Background technique [0002] At present, the gesture recognition functions of smart touch devices such as mobile phones and large-size tablets on the market are very rough. For example, the five-finger grabbing gesture is set in the ipad to close the current application. apps cannot take advantage of the five-finger grab gesture.
