Detailed Description
The invention is described in further detail below with reference to the following figures and specific examples:
the system for recognizing the gesture of the interconnected split screen projection of the mobile phone as shown in fig. 1 comprises a mobile phone 1 and a computer terminal 2 (such as a car machine and the like), wherein the mobile phone 1 is used for establishing a split screen projection channel with the computer terminal 2, the computer terminal 2 is used for displaying a mobile phone virtual screen interface of the mobile phone 1, the mobile phone 1 is used for starting a mobile phone camera and displaying a gesture recognition function interface, the mobile phone 1 captures a user gesture operation by calling the mobile phone camera by using a gesture recognition function, and a mouse indication icon is arranged on the mobile phone virtual screen interface and indicates a coordinate position which can be clicked currently, as shown in fig. 2;
the mobile phone 1 is further configured to convert a change in a position of a single-finger Gesture when the single-finger Gesture recognized in the Gesture Recognition area of the mobile phone camera moves into a synchronous change in a position of a mouse-like indication icon on a virtual screen of the mobile phone through a Gesture Recognition SDK (software development kit) such as a space cloud Gesture Recognition software (GR), and when the single-finger Gesture is not recognized, the mouse-like indication icon stays at a current position;
the mobile phone 1 is further configured to convert a confirmation Gesture operation (OK Gesture) recognized in the Gesture Recognition area of the mobile phone camera into a click event of the current position of the mouse type indication icon on the virtual screen interface of the mobile phone through a Gesture Recognition SDK (software development kit) such as a getter Recognition software (GR).
In the above technical solution, the mobile phone 1 is further configured to convert a Gesture canceling operation (a fist making Gesture) recognized in a Gesture Recognition area of the mobile phone camera into a Gesture moving operation of canceling the current single finger through a Gesture Recognition SDK (software development kit) such as a getter cloud Gesture Recognition software (GR).
In the above technical solution, the gesture recognition area of the mobile phone camera is parallel to the screen of the computer terminal 2. When the gesture is recognized, the gesture moves left and right in the direction just the same as the direction of the screen, and the accuracy of gesture recognition and coordinate conversion of the virtual screen interface of the mobile phone is guaranteed.
In the above technical solution, the application program of the mobile phone 1 recognizes the current movement of the single-finger gesture through the camera, determines the control event of the position change when the single-finger gesture moves, and converts the coordinates of the single-finger gesture recognized by the mobile phone 1 into the coordinates of the mouse-like indication icon on the virtual screen interface of the mobile phone in a coordinate transformation manner, so that the mouse-like indication icon on the virtual screen interface of the mobile phone performs the synchronous position change.
In the above technical solution, the initial position of the mouse type indication icon on the virtual screen interface of the mobile phone is defaulted to be the central point of the virtual screen interface of the mobile phone. When the user performs gesture operation, the viewed interface is the interface of the virtual screen, so that the user needs to see where the current mouse type indication icon is, and the user can conveniently perform accurate gesture control on the mouse type indication icon. When a user uses a single hand to move up, down, left and right, the virtual screen mouse type indication icon is synchronously moved according to the position and the moving speed identified by the gesture, so that the user can conveniently click.
In the above technical solution, the mobile phone 1 multiplies the moving distance d of the single-finger gesture recognized in the gesture recognition area of the mobile phone camera by a preset coefficient a, the moving distance is used as the moving distance of the mouse-like indication icon on the virtual screen of the mobile phone, the coefficient a is defaulted to 1, and the coefficient a can be adjusted according to the actual use scene. For example, the space for gesture movement is small, and the factor can be increased by 2 times.
In the above technical solution, a specific method for converting the gesture confirmation operation into a click event of the current position of the mouse type indication icon on the virtual screen interface of the mobile phone 1 is as follows: the mobile phone application program records the position coordinates of a mouse type indication icon on a mobile phone virtual screen interface formed by single-finger gesture operation;
when the gesture confirmation operation is recognized in the gesture recognition area of the mobile phone camera, the mobile phone application program converts the coordinate corresponding to the gesture confirmation operation into the position coordinate of the mouse type indication icon on the mobile phone virtual screen interface, and a click event is injected into the position corresponding to the position coordinate of the mouse type indication icon on the mobile phone virtual screen interface at the moment. And carrying out corresponding click action prompt on a mouse type indication icon on the virtual screen interface of the mobile phone, such as a click animation displayed by the mouse.
In the technical scheme, the left-right swinging palm action recognized in the gesture recognition area of the mobile phone camera is defined as a dragging event by the mobile phone 1 and is directly injected into a virtual screen interface of the mobile phone;
in this embodiment, the application layer is controlled to apply an own interface by using an api, a discrete touch event provided by the Android, so as to implement the above injection click event and the drag event.
In the above technical solution, the mobile phone 1 displays the gesture recognition interface to replace the lock screen or display the lock screen mask, or the mobile phone 1 displays the gesture recognition interface by overlapping on the basis of the lock screen or the display of the lock screen mask. When the mobile phone 1 is interconnected with the computer terminal 2, the mobile phone 1 runs an application program, and the mobile phone 1 displays a mask interface for successful interconnection as shown in fig. 2. When a user wants to switch to gesture operation, the user can start the gesture recognition function by clicking the button of the mask interface, start the video recording of the mobile phone camera, and recognize the current user gesture by using the gesture recognition module, as shown in fig. 3.
In the technical scheme, hundred million driving assistants or driving partner application programs are installed on the mobile phone 1, hundred million mobile phone interconnection is installed on the computer terminal 2, and a split screen projection channel between the mobile phone 1 and the computer terminal 2 can be realized by utilizing a mobile phone interconnection technology.
