[0002] With the development of human-computer interaction technology, air mouse devices are widely used in remotely controlling display devices, such as televisions, projectors, and smart large screens. The air mouse device detects gesture actions through motion sensors such as acceleration sensors and gyroscopes to control the movement of the cursor on the display screen. In actual use, the cursor position is prone to deviation due to sensor drift, error accumulation, or screen edge limitations, resulting in the cursor being unable to accurately respond to user operations. Therefore, it is necessary to calibrate the cursor position.

[0026] Embodiment 1

[0027] Figure 1It is a flowchart of the cursor position calibration method provided in Embodiment 1. This embodiment is applicable to the situation where the cursor position corresponding to the air mouse device is offset and the cursor needs to be positionally calibrated. This method can be executed by a cursor position calibration device, which is implemented in the form of hardware and / or software and can be integrated into the air mouse device running this system.

[0028] As Figure 1 shown, the method includes:

[0029] S110. In the air mouse mode, in response to detecting that the current gesture corresponding to the air mouse device matches a preset calibration gesture, determine the projection coordinates of the air mouse pointing line on the display screen;

[0030] S120. Based on the projection coordinates and the preset calibration coordinates, determine the cursor offset vector corresponding to the air mouse device;

[0031] S130. Based on the cursor offset vector, perform position calibration on the cursor corresponding to the air mouse device.

[0032] Among them, the air mouse device is also known as an air mouse, air mouse, or flying mouse (Air mouse). It is a mouse that can be used in the air and can be used to remotely control the cursor movement of a display device. The air mouse mode refers to a functional mode in which the cursor of a display device is controlled by operating an air mouse device.

[0033] The current gesture corresponding to the air mouse device can be determined based on the acceleration data and angular velocity data of the air mouse device. Among them, the acceleration data and angular velocity data can be respectively collected by an acceleration sensor and a gyroscope configured in the air mouse device.

[0034] The calibration gesture is preset and used to trigger the position calibration of the cursor corresponding to the air mouse device. Embodiment of the present application supports users to set the calibration coordinates according to their own operation habits. Optionally, by limiting the angle change range and angle change speed between the normal line of the display screen and the air mouse pointing line, the setting of the standard gesture is realized.

[0035] In the air mouse mode, the gesture actions corresponding to the air mouse device are recognized. If it is detected that the current gesture corresponding to the air mouse device matches the preset calibration gesture, trigger the position calibration of the cursor corresponding to the air mouse device. Specifically, determine the projection coordinates of the air mouse pointing line on the display screen, determine the cursor offset vector corresponding to the air mouse device based on the projection coordinates and the preset calibration coordinates; based on the cursor offset vector, perform position calibration on the cursor corresponding to the air mouse device.

[0036] Among them, the air mouse pointing line refers to the cursor line that follows the movement of the air mouse device on the display screen when the air mouse device moves in the air in the air mouse mode. The projection coordinate refers to the intersection coordinate of the air mouse pointing line and the plane where the display screen is located. The projection coordinate is used to determine the current position of the cursor corresponding to the air mouse device on the display screen.

[0037] Among them, the calibration coordinate is pre-determined and corresponds to a certain position on the display screen. The calibration coordinate is the target position for repositioning the cursor corresponding to the air mouse device. That is to say, after the position calibration of the cursor corresponding to the air mouse device is completed, the cursor corresponding to the air mouse device will appear at the screen position represented by the calibration coordinate. The embodiments of the present application support the user to set the calibration coordinate according to their own operation habits. That is to say, the calibration coordinate can correspond to any position on the display screen and is not limited here. In an optional embodiment, the preset calibration coordinate is set as the center coordinate of the display screen. Such a setting is more in line with the conventional operation habits.

[0038] Optionally, calculate the difference between the projection coordinate and the calibration coordinate, and use the calculated difference as the cursor offset vector corresponding to the air mouse device. Among them, the cursor offset vector is used to quantify the relative angle and relative distance between the current position of the cursor corresponding to the air mouse device on the display screen and the target position of repositioning.

[0039] Taking the calibration coordinate set as the center coordinate of the display screen as an example, the determination process of the cursor offset vector is described as follows: First, determine the resolution of the display screen, and determine the calibration coordinate based on the resolution of the display screen. For example, if the resolution of the display screen is W×H, then the calibration coordinate can be determined as Use (X, Y) to represent the projection coordinate. Then, use Calculate the difference between the projection coordinate and the calibration coordinate. Then, the cursor offset vector can be expressed as (dx, dy).

[0040] Based on the cursor offset vector, the relative angle and relative distance between the current position of the cursor corresponding to the air mouse device on the display screen and the target position of repositioning can be determined. When the relative angle and relative distance are determined, the moving distance and moving direction of the cursor corresponding to the air mouse device can be further determined, and based on the moving distance and moving direction, the cursor corresponding to the air mouse device is repositioned from the current position to the screen position corresponding to the calibration coordinate.

[0041] In the technical solution of the embodiment of the present application, in the air mouse mode, in response to detecting that the current gesture corresponding to the air mouse device matches the preset calibration gesture, the projection coordinates of the air mouse pointing line on the display screen are determined; based on the projection coordinates and the preset calibration coordinates, the cursor offset vector corresponding to the air mouse device is determined; based on the cursor offset vector, the position of the cursor corresponding to the air mouse device is calibrated. By presetting the calibration gesture as the condition for triggering the position calibration of the cursor, the user can complete the calibration of the cursor position without exiting the air mouse mode only by gesture actions, maintaining the operation coherence and improving the user experience. The calibration process of the cursor position is simplified and the calibration efficiency is improved. By triggering the position calibration of the cursor by gesture, the user does not have to face the display screen to keep the air mouse pointing line continuously pointing to the repositioning target position during the cursor position calibration, and the user can hold the air mouse device in any posture, improving the user experience.

[0042] In an optional embodiment, the calibrating the position of the cursor corresponding to the air mouse device based on the cursor offset vector includes: determining a moving distance and a moving direction for the cursor corresponding to the air mouse device based on the cursor offset vector; controlling the cursor corresponding to the air mouse device to move to the screen position corresponding to the calibration coordinates based on the moving distance and the moving direction, and controlling the display screen to display the cursor moving process.

[0043] The cursor offset vector is used to quantify the relative angle and relative distance between the current position of the cursor corresponding to the air mouse device on the display screen and the repositioning target position.

[0044] Based on the relative distance and relative angle, a moving distance and a moving direction can be determined for the cursor corresponding to the air mouse device. Based on the moving distance and the moving direction, the cursor corresponding to the air mouse device is controlled to move to the screen position corresponding to the calibration coordinates.

[0045] The air mouse device controls the display screen to display the cursor moving process through its own configured communication module, such as a Bluetooth module. Optionally, the display device to which the display screen belongs is provided with a communication interface and is deployed with a standard display screen coordinate mapping algorithm. Optionally, the cursor moving process is displayed on the display screen in the form of an animation as the calibration feedback provided to the user to notify the user that the position of the cursor has been calibrated.

[0046] In the above technical solution, based on the cursor offset vector, the position of the cursor corresponding to the air mouse device is calibrated, and the cursor is repositioned to the screen position corresponding to the calibration coordinates, which provides convenience for the user operation and facilitates the user to more accurately control the cursor movement. In the above technical solution, the cursor moving process is displayed on the display screen, which is convenient for the user to intuitively understand the cursor calibration process and is beneficial to improving the user experience.

[0047] In an optional embodiment, after calibrating the cursor corresponding to the air mouse device based on the cursor offset vector, the method further includes: in response to detecting a gesture change corresponding to the air mouse device, determining a coordinate change of the air mouse pointing line on the display screen; based on the cursor offset vector and the coordinate change, controlling the cursor corresponding to the air mouse device to move starting from the calibrated coordinates in response to the coordinate change.

[0048] It can be known that the air mouse device detects gesture actions through motion sensors such as an acceleration sensor and a gyroscope to control the movement of the cursor on the display screen. After calibrating the cursor corresponding to the air mouse device, if a gesture change corresponding to the air mouse device is detected, it indicates that the user attempts to control the cursor on the display device by operating the air mouse device. The gesture change corresponding to the air mouse device will bring about a coordinate change of the air mouse pointing line on the display screen. Among them, the coordinate change of the air mouse pointing line on the display screen means that the projected coordinates of the air mouse pointing line on the display screen change. The cursor offset vector quantifies the relative angle and relative distance between the current position and the repositioned target position of the cursor corresponding to the air mouse device on the display screen. Keeping the relative angle and relative distance between the projected coordinates and the calibrated coordinates unchanged, the cursor corresponding to the air mouse device is controlled to move starting from the standard coordinates according to the coordinate change to respond to the user's operation on the air mouse device.

[0049] In the above technical solution, after calibrating the cursor corresponding to the air mouse device, the cursor corresponding to the air mouse device is controlled to move starting from the calibrated coordinates based on the cursor offset vector and the gesture change corresponding to the air mouse device, ensuring the response speed and response accuracy of the air mouse device to the user's operation.

[0050] Embodiment 2

[0051] Figure 2 is a flowchart of the cursor position calibration method provided according to Embodiment 2. This embodiment is further optimized based on the above embodiment.

[0052] As Figure 2 shown, the method includes:

[0053] S210. Based on the acceleration data and angular velocity data of the air mouse device, determining the angle change range and angle change speed between the normal line of the display screen and the air mouse pointing line.

[0054] Among them, the acceleration data can be collected through an acceleration sensor and a gyroscope configured in the air mouse device itself. The acceleration data and angular velocity data are used to determine the angle change range and angle change speed between the normal line of the display screen and the air mouse pointing line.

[0055] Among them, the angle change range and the angle change speed are used to determine the current gesture corresponding to the air mouse device.

[0056] S220. Based on the angle change range and the angle change speed, determine the current gesture corresponding to the air mouse device.

[0057] Recognizing the current gesture can determine whether the user wants to perform position calibration on the cursor corresponding to the air mouse device.

[0058] S230. Match the current gesture corresponding to the air mouse device with a preset calibration gesture.

[0059] The calibration gesture is preset and used to trigger position calibration of the cursor corresponding to the air mouse device. Embodiments of the present application support users to set calibration coordinates according to their own operation habits. Optionally, by limiting the angle change range and the angle change speed between the normal line of the display screen and the air mouse pointing line, the setting of the standard gesture is realized.

[0060] Optionally, respectively match the angle change range and the angle change speed corresponding to the current gesture with the angle change range and the angle change speed corresponding to the calibration gesture.

[0061] S240. In the air mouse mode, in response to detecting that the current gesture corresponding to the air mouse device matches the preset calibration gesture, determine the projection coordinates of the air mouse pointing line on the display screen.

[0062] Optionally, if the angle change range and the angle change speed corresponding to the standard gesture match the angle change range and the angle change speed corresponding to the current gesture, it is determined that the current gesture corresponding to the air mouse device matches the preset calibration gesture, indicating that the user wants to perform position calibration on the cursor corresponding to the air mouse device, and then trigger position calibration of the cursor corresponding to the air mouse device.

[0063] S250. Based on the projection coordinates and the preset calibration coordinates, determine the cursor offset vector corresponding to the air mouse device.

[0064] S260. Based on the cursor offset vector, perform position calibration on the cursor corresponding to the air mouse device.

[0065] The technical solution of this application provides a practical gesture recognition solution and a gesture matching solution, providing technical support for calibrating the position of the cursor corresponding to the air mouse device based on gesture triggering. In the technical solution of this application, the acceleration data and angular velocity data used to recognize the current gesture can be obtained through the existing acceleration sensor and gyroscope of the air mouse device. That is to say, the technical solution of this application can achieve gesture recognition, gesture matching, and subsequent cursor position calibration through software algorithms without additional hardware costs, effectively controlling the cost of the cursor position calibration method.

[0066] In an optional embodiment, the matching of the current gesture corresponding to the air mouse device with a preset calibration gesture includes: parsing the preset calibration gesture to determine the angle change threshold and change speed threshold corresponding to the calibration gesture; if the angle change range is greater than or equal to the angle change threshold and the angle change speed is greater than or equal to the change speed threshold, it is determined that the current gesture corresponding to the air mouse device matches the preset calibration gesture.

[0067] Optionally, by limiting the angle change range and angle change speed between the normal line of the display screen and the air mouse pointing line, the setting of the standard gesture is realized. Parsing the preset calibration gesture can determine the angle change threshold and change speed threshold corresponding to the calibration gesture. Generally speaking, the calibration gesture should be distinguishable from the cursor control gesture.

[0068] Among them, the angle change threshold is used to determine whether the current gesture matches the calibration gesture from the dimension of the angle change range. The angle change threshold supports the user to set according to their own operation habits, and the specific value of the angle change threshold is not limited here. Optionally, the angle change threshold corresponding to the calibration gesture is set to be greater than 90 degrees. If the included angle between the normal line of the display screen and the air mouse pointing line changes from an acute angle to an obtuse angle and the change range is greater than 90 degrees, it can be determined that the angle change range corresponding to the current gesture is greater than or equal to the angle change threshold.

[0069] Among them, the change speed threshold is used to determine whether the current gesture matches the calibration gesture from the dimension of the angle change speed. The change speed threshold supports the user to set according to their own operation habits, and the specific value of the change speed threshold is not limited here. Optionally, the change speed threshold is greater than the upper limit of the change speed corresponding to the cursor control gesture. The upper limit of the change speed corresponding to the cursor control gesture can be obtained through statistical analysis of the angle change speed corresponding to the cursor control gesture.

[0070] When the angle change range is greater than or equal to the angle change threshold and the angle change speed is greater than or equal to the change speed threshold, it indicates that the current gesture corresponding to the air mouse device matches the preset calibration gesture. At this time, the position calibration of the cursor corresponding to the air mouse device can be started.

[0071] In the above technical solution, by defining the angle change range and the angle change speed between the normal line of the display screen and the air mouse pointing line, the setting of the standard gesture is realized. Matching the current gesture and the preset gesture from two dimensions of the angle change range and the angle change speed is beneficial to improving the recognition rate of the gesture and provides a strong guarantee for the success rate of the cursor position calibration.

[0072] Figure 3 It is a schematic diagram of a cursor position calibration method provided according to an embodiment of the present application. Refer to Figure 3 , in the case where the user wants to perform position calibration on the cursor whose position has shifted, the user holds the air mouse device and waves it according to the preset calibration gesture. For example, it can be like Figure 3 such that the air mouse pointing line forms a certain circular motion, triggering the position calibration of the cursor. Control the cursor corresponding to the air mouse device to move from the current position to the repositioned target position according to the moving direction and moving distance corresponding to the cursor offset vector. The cursor movement process is displayed on the display screen in the form of an animation as calibration feedback provided to the user to notify the user that the position of the cursor has been calibrated.
