Based on the above embodiments, fig. 2 is a schematic flow chart of a cursor control method in an embodiment. On the basis of the above embodiment, the present embodiment adds a step of updating the offset of the horizontal azimuth angle of the air mouse carrier device, so as to solve the problem that the accumulated error of the offset is larger and larger with the accumulation of time. By timely estimating and updating the horizontal azimuth offset condition of the air mouse carrier device and feeding back the horizontal azimuth offset condition to relevant calculation of cursor target position updating in real time, the displacement of the cursor can be guaranteed to accurately reflect the space posture change of the air mouse carrier device, the alignment of the cursor position and the space posture of the air mouse carrier device is guaranteed, the accurate remote control of the air mouse cursor is realized, and the use experience of an air mouse user under the condition of no magnetometer calibration can be improved.
As shown in fig. 2, the cursor control method includes the following steps:
step 210, determining the variation of the space attitude of the air mouse carrier device, wherein the variation comprises a first variation of the horizontal azimuth angle.
Step 220, determining whether the empty mouse carrier device is in a static state.
In one embodiment, the determining whether the empty mouse carrier device is in a resting state comprises: determining whether the air mouse carrier device is in a resting state based on sensing data of a motion sensor associated with the air mouse carrier device. Specifically, for example, the motion sensor includes an accelerometer, if the data of the accelerometer read at the current moment is 0, it may be determined that the air mouse carrier device is in a stationary state at the current moment, that is, the air mouse carrier device is not moved or rotated, otherwise, it is determined that the air mouse carrier device is in a non-stationary state at the current moment. Alternatively, the data of the gyro sensor read at two adjacent moments can be used to determine whether the empty mouse carrier device is in a stationary state. In general terms, whether the air mouse carrier device is in a standing state at the current moment can be judged by monitoring the sensing data of the motion sensor (accelerometer and gyroscope) based on the amplitude value, fluctuation condition and the like of the sensing data.
Step 230, if the air mouse carrier device is in a standing state, determining a current offset of the horizontal azimuth, and updating a historical offset of the horizontal azimuth based on the current offset to obtain a historical latest offset of the horizontal azimuth.
Because the space attitude of the air mouse carrier device changes in the using process, the attitude angle of the air mouse carrier device changes, the horizontal azimuth offset of the air mouse carrier device is inconvenient to estimate in the moving process of the air mouse carrier device, or the horizontal azimuth offset of the air mouse carrier device is estimated when the air mouse carrier device is in the moving process, and the air mouse carrier device has the problems of large calculated amount, high calculation complexity or low precision. In view of the above, in this embodiment, the interaction gap between the user and the air mouse carrier device is used as the estimation and update timing of the horizontal azimuth offset, that is, the offset of the horizontal azimuth is obtained when the air mouse carrier device is in a static state, the historical offset is updated by using the offset, and the offset is used as the historical latest offset to participate in the subsequent step of correcting the first offset of the horizontal azimuth, so that the correction precision can be improved, and the remote control precision of the air mouse cursor can be further improved.
If the air mouse carrier device is in a static state, the space attitude angle of the air mouse carrier device should be kept unchanged theoretically, and the change amount of the horizontal azimuth angle of the air mouse carrier device determined based on the two adjacent frames of sensing data is the offset of the horizontal azimuth angle. Further, the offset at successive moments during the standing state of the air mouse carrier device may be averaged as the current offset of the horizontal azimuth angle.
Specifically, in one embodiment, the determining the current offset of the horizontal azimuth angle includes: determining a reference variation of the horizontal azimuth based on two adjacent frames of sensing data of a motion sensor associated with the air mouse carrier device; and determining the current offset according to the reference variation. The determining the current offset according to the reference variation includes: determining the reference variation as the current offset; or determining the average value of the reference variation amount in the period of time when the empty mouse carrier device is in a static state as the current offset amount. The accuracy of determining the current offset can be further improved by determining the current offset based on an average value of the offsets determined by two adjacent frames of sensing data during a period in which the air mouse carrier device is in a stationary state, or in other words, determining an average value of the variation of the horizontal azimuth angle between two adjacent times during a period in which the air mouse carrier device is in a stationary state as the current offset.
The updating of the historical offset of the horizontal azimuth angle based on the current offset may specifically be to replace the historical offset with the current offset, that is, the current offset becomes the historical offset, and the last updated historical offset is the latest historical offset.
And step 240, correcting the first variation based on the historical latest offset of the horizontal azimuth angle of the air mouse carrier device, and obtaining a corrected second variation of the horizontal azimuth angle.
Specifically, in one embodiment, the correcting the first variation based on the historical latest offset of the horizontal azimuth angle of the air mouse carrier device includes: determining a difference between the first amount of change and the historical latest offset; the difference is determined as a second amount of change in the corrected azimuth angle.
And 250, determining the target position of the air mouse cursor according to the second variation.
And 260, controlling the mouse cursor to move to the target position.
According to the technical scheme of the embodiment, on the basis of the embodiment, the step of updating the offset of the horizontal azimuth angle of the air mouse carrier device is added, so that the problem that the accumulated error of the offset is larger and larger along with accumulation of time is solved. By timely estimating and updating the horizontal azimuth offset condition of the air mouse carrier device and feeding back the horizontal azimuth offset condition to relevant calculation of cursor target position updating in real time, the displacement of the cursor can be guaranteed to accurately reflect the space posture change of the air mouse carrier device, the alignment of the cursor position and the space posture of the air mouse carrier device is guaranteed, the accurate remote control of the air mouse cursor is realized, and the use experience of an air mouse user under the condition of no magnetometer calibration can be improved.
Based on the foregoing embodiment, fig. 3 is a schematic flow chart of a cursor control method in an embodiment, which specifically includes: and reading sensing data of a motion sensor (accelerometer and gyroscope) associated with the air mouse carrier device, determining the change amount of the spatial attitude of the air mouse carrier device based on the sensing data, correcting the change amount by using the historical latest offset of the horizontal azimuth angle, determining the target position of the cursor based on the corrected change amount, and updating. After the sensing data of the motion sensor associated with the air mouse carrier device is read, the method further comprises the step of judging whether the air mouse carrier device is in a standing state, and if so, performing estimation and update operation of the horizontal azimuth offset to obtain a historical latest offset. And updating the offset of the horizontal azimuth angle in time every time the air mouse carrier device is monitored to be in a static state. If the device is in motion, the updating operation of the horizontal azimuth offset is not performed.
In this embodiment, the interaction gap between the user and the air mouse carrier device is used as the estimation and update time of the horizontal azimuth angle offset, that is, the offset of the horizontal azimuth angle of the air mouse carrier device is obtained when the air mouse carrier device is in a static state, the historical offset is updated by using the offset, and the offset is used as the historical latest offset to participate in the subsequent step of correcting the first offset of the horizontal azimuth angle, so that the correction precision can be improved, and the remote control precision of the air mouse cursor can be further improved.
