As shown in fig. 1, the method may specifically include the following steps:
and 110, determining the variation of the space attitude of the empty mouse carrier equipment, wherein the variation comprises a first variation of a horizontal azimuth angle.
The empty mouse carrier device refers to a terminal serving as an empty mouse remote controller, such as a smart phone or a remote controller.
In one embodiment, determining the amount of change in the spatial attitude of the empty rat carrier device comprises:
determining the spatial attitude of the empty mouse carrier device based on the sensing data of the motion sensor associated with the empty mouse carrier device; and determining the variation of the spatial attitude based on the spatial attitudes of the empty rat carrier device respectively determined by the sensing data of two adjacent frames, or in other words, determining the variation of the spatial attitude based on the spatial attitudes of the empty rat carrier device respectively determined by the sensing data detected at adjacent moments.
Specifically, the motion sensor may include two types of accelerometers and gyroscopes, or may include three types of accelerometers, gyroscopes, and magnetometers. The motion sensor is usually provided in the air mouse carrier device, for example, an accelerometer and a gyroscope are usually arranged in a smart phone; or additionally arranging equipment for realizing the function of the empty mouse carrier. The spatial attitude of the empty rat carrier equipment can be estimated by carrying out fusion calculation on the sensing data detected by the motion sensor. The spatial attitude of the air mouse carrier device is generally represented by a horizontal azimuth angle, a pitch angle and a roll angle. Wherein, the horizontal azimuth specifically refers to the horizontal declination between the pointing direction of the empty rat carrier equipment and the magnetic north pole.

At present, most air mouse carrier devices only use an accelerometer and a gyroscope as data sources for determining the spatial attitude of the air mouse carrier device due to the reasons of hardware cost, large indoor magnetic field interference of a magnetometer and the like. However, the absence of the magnetometer causes the data source to lack the reference data in the direction of the magnetic north pole, so the estimation of the horizontal azimuth angle of the air mouse carrier device may be shifted, and the accumulated shift amount may become larger with time, causing the actual displacement of the cursor to deviate (be smaller than or larger than) the theoretical value, further causing the position of the cursor to be misaligned with the spatial attitude of the air mouse carrier device, which affects the user experience. To solve the problem, in the technical solution of this embodiment, a step of correcting the first variation of the horizontal azimuth based on the historical latest offset of the horizontal azimuth of the empty rat carrier device is added to improve the accuracy of determining the variation of the horizontal azimuth, thereby improving the accuracy of determining the position of the empty rat cursor, improving the consistency between the position of the cursor and the spatial attitude of the empty rat carrier device, realizing accurate remote control of the cursor, and improving user experience,
and step 130, determining the target position of the mouse cursor according to the second variable quantity.

In an embodiment in which the target position of the air mouse cursor is determined based on the mapping relationship between the amount of change in the spatial posture of the air mouse carrier device and the amount of change in the cursor position, the target position of the air mouse cursor may be determined specifically by the position of the air mouse cursor at the previous time and the amount of movement of the air mouse cursor in the time period from the previous time to the current time. In an embodiment of determining the target position of the empty mouse cursor based on the mapping relationship between the spatial posture of the empty mouse carrier device and the position of the empty mouse cursor, the mapping relationship between the initial position of the empty mouse carrier device and the preset initial position of the empty mouse cursor may be used to determine the relative position between the spatial posture of the empty mouse carrier device and the initial position at each moment, and further determine the target position of the empty mouse cursor according to the relative position and the preset initial position of the empty mouse cursor, and the relative position between the target position of the empty mouse cursor and the initial position thereof is consistent with the relative position between the spatial posture of the empty mouse carrier device and the initial position thereof.
And 140, controlling the air mouse cursor to move to the target position.
According to the cursor control method provided by the embodiment of the disclosure, after a variation (including a first variation of a horizontal azimuth) of a spatial attitude of an empty mouse carrier device is determined, the first variation is corrected based on a historical latest offset of the horizontal azimuth of the empty mouse carrier device, and a second corrected variation of the horizontal azimuth is obtained; and finally, determining the target position of the air mouse cursor according to the second variable quantity, and controlling the air mouse cursor to move to the target position. The first variable quantity is corrected based on the historical latest offset of the horizontal azimuth angle of the air mouse carrier equipment, so that the determination precision of the space attitude variable quantity of the air mouse carrier equipment can be improved, the determination precision of the target position of an air mouse cursor is further improved, the accurate remote control of the cursor is realized, the consistency between the cursor position and the space attitude of the air mouse carrier equipment is improved, and the use experience of a user is favorably improved.
On the basis of the foregoing embodiment, fig. 2 is a flowchart illustrating a cursor control method according to an embodiment. On the basis of the above embodiment, the present embodiment adds a step of updating the offset of the horizontal azimuth of the air mouse carrier device, so as to solve the problem that the accumulated error of the offset is larger and larger as time is accumulated. The offset condition of the horizontal azimuth angle of the air mouse carrier equipment is estimated and updated in time and fed back to the correlation calculation of cursor target position updating in real time, so that the displacement of the cursor can accurately reflect the change of the space posture of the air mouse carrier equipment, the alignment of the cursor position and the space posture of the air mouse carrier equipment 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:
and 210, determining the variation of the space attitude of the empty mouse carrier equipment, wherein the variation comprises a first variation of a horizontal azimuth angle.
And step 220, determining whether the empty mouse carrier equipment is in a standing state.
In one embodiment, the determining whether the empty rat carrier device is in a resting state comprises: determining whether the empty rat carrier device is in a static state based on sensing data of a motion sensor associated with the empty rat carrier device. Specifically, for example, the motion sensor includes an accelerometer, and if the data read by the accelerometer at the current time is 0, it may be determined that the empty and mouse carrier device at the current time is in a stationary state, that is, the empty and mouse carrier device is not moved or rotated, otherwise, it is determined that the empty and mouse carrier device at the current time is in a non-stationary state. Or, whether the empty rat carrier device is in a standing state or not can be determined by using the data of the gyroscope sensor read at two adjacent moments. In a general way, by monitoring the sensing data of the motion sensor (the accelerometer and the gyroscope), whether the air mouse carrier device is in a standing state at the current moment can be judged based on the amplitude, fluctuation and the like of the sensing data.
Because the attitude angle of the empty mouse carrier device changes due to the change of the spatial attitude in the using process of the empty mouse carrier device, the offset of the horizontal azimuth angle of the empty mouse carrier device is inconvenient to estimate in the moving process of the empty mouse carrier device, or the offset of the horizontal azimuth angle of the empty mouse carrier device is estimated in the moving process of the empty mouse carrier device, so that the problems of large calculation amount, high calculation complexity or low precision exist. In view of the above problems, in this embodiment, the interaction gap between the user and the empty mouse carrier device is used as the timing for estimating and updating the horizontal azimuth offset, that is, the offset of the horizontal azimuth of the empty mouse carrier device is obtained when the empty 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 accuracy can be improved, and further, the remote control accuracy of the empty mouse cursor can be improved.
If the empty mouse carrier equipment is in a standing state, the spatial attitude angle of the empty mouse carrier equipment is theoretically kept unchanged, and the variable quantity of the horizontal azimuth angle of the empty mouse carrier equipment determined based on two adjacent frames of sensing data is the offset of the horizontal azimuth angle. Further, the offset of the air mouse carrier device at continuous time can be averaged during the standing state as the current offset of the horizontal azimuth.
Specifically, in an embodiment, the determining the current offset of the horizontal azimuth includes: determining a reference variation amount of the horizontal azimuth based on two adjacent frames of sensing data of a motion sensor associated with the empty rat carrier device; and determining the current offset according to the reference variable quantity. The determining the current offset according to the reference variation includes: determining the reference variation as the current offset; or, determining an average value of the reference variation in a time period in which the empty rat carrier apparatus is in a stationary state as the current offset. The current offset is determined based on the average value of the offsets determined by the two adjacent frames of sensing data in the time period when the empty rat carrier device is in the standing state, or in other words, the average value of the variation of the horizontal azimuth angle between two adjacent moments in the time period when the empty rat carrier device is in the standing state is determined as the current offset, so that the determination accuracy of the current offset can be further improved.
The historical offset of the horizontal azimuth is updated based on the current offset, specifically, the current offset is used to replace the historical offset, that is, the current offset becomes the historical offset, and the last updated historical offset is the latest historical offset.
And 240, correcting the first variable quantity based on the historical latest offset of the horizontal azimuth of the empty rat carrier equipment to obtain a second variable quantity of the corrected horizontal azimuth.
Specifically, in an embodiment, the correcting the first variation based on the historical latest offset of the horizontal azimuth of the empty rat carrier device includes: determining a difference between the first variance and the historical latest offset; determining the difference as a second variation of the corrected horizontal azimuth.
And step 250, determining the target position of the mouse cursor according to the second variable quantity.
And step 260, controlling the air mouse cursor to move to the target position.
In the technical solution of this embodiment, on the basis of the above embodiment, a step of updating the offset of the horizontal azimuth of the air mouse carrier device is added to solve the problem that the accumulated error of the offset is larger and larger as time accumulates. The offset condition of the horizontal azimuth angle of the air mouse carrier equipment is estimated and updated in time and fed back to the correlation calculation of cursor target position updating in real time, so that the displacement of the cursor can accurately reflect the change of the space posture of the air mouse carrier equipment, the alignment of the cursor position and the space posture of the air mouse carrier equipment 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.
On the basis of the foregoing embodiment, fig. 3 is a schematic flowchart of a cursor control method in an implementation manner, which specifically includes: the method comprises the steps of reading sensing data of a motion sensor (an accelerometer and a gyroscope) related to the empty and mouse carrier equipment, determining the variable quantity of the space attitude of the empty and mouse carrier equipment based on the sensing data, correcting the variable quantity by utilizing the historical latest offset of a horizontal azimuth, and determining and updating the target position of a cursor based on the corrected variable quantity. After the sensing data of the motion sensor associated with the empty mouse carrier device is read, whether the empty mouse carrier device is in a standing state or not is judged, and if the empty mouse carrier device is in the standing state, estimation and updating operations of horizontal azimuth offset are carried out to obtain historical latest offset. And updating the offset of the horizontal azimuth in time when the empty rat carrier equipment is monitored to be in a standing state. And if the equipment is in a motion state, not performing the updating operation of the horizontal azimuth offset.
In this embodiment, the interactive gap between the user and the empty mouse carrier device is used as the timing for estimating and updating the horizontal azimuth offset, that is, the offset of the horizontal azimuth of the empty mouse carrier device is obtained when the empty 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 accuracy can be improved, and further the remote control accuracy of the empty mouse cursor can be improved.
