Problems solved by technology

[0007] If in a multi-device gesture interaction environment, each device runs its own gesture interaction method independently, then multiple devices cannot cooperate well, and there will be conflicts in gesture recognition: for the same air gesture, Kinect-based interaction and camera-based interaction The results recognized by different interactive methods may be different, and even a certain method cannot be recognized

Embodiment Construction

[0072] exist figure 1 Among them, a multi-device-oriented gesture interaction method includes the following steps:

[0073] The first step is to generate a general gesture set G, G=G touch ∪G air , where G touch Finger touch gesture set, G air Finger gesture set:

[0074] 1.1 Generate touch gesture set G touch ,the way is:

[0075] 1.1.1 Use a quadruple composed of Pid, ​​State, Coordinate, and Time to define the touch point Point, Point=(Pid, State, Coordinate, Time), where the value of Pid is a natural number, referring to multiple detected touch points The serial number of the touch point; State refers to the state of the touch point, and the value is an element in the set STATE, set STATE={Appear, Move, Leave}, Appear, Move, and Leave respectively indicate that the touch interaction device detects that the touch point appears, In moving and leaving; Coordinate is a binary real array, which refers to the coordinates of the touch point; Time refers to the system time ...

Abstract

The invention discloses a gesture interactive method capable of being compatible with multiple interactive devices and based on a universal gesture set. The method includes the steps that the universal gesture set is generated, gesture set designation is conducted through the multiple devices, gesture mapping is conducted through application programs, and gesture recognition is conducted through the multiple devices.

Description

[0001] Technical field [0002] The invention relates to a gesture interaction method, in particular to a multi-device gesture interaction method based on a general gesture set. Background technique [0003] Under the guidance of the concept of human-centered interaction, the research of human-computer interaction tries to break through the limitations of the mouse and keyboard to achieve a more free and harmonious interaction prospect. Gesture is one of the most important channels of natural interaction, and it is also a research hotspot. There are already many devices that support gesture interaction on the market. [0004] According to different user operation methods, devices supporting gesture interaction can be divided into four categories. According to whether the user is in contact with the display screen during operation, the devices are divided into touch interactive devices and non-touch interactive devices. According to whether the user operates with the aid of a...
