Referring to FIG. 1, a flow diagram of some embodiments of a cursor position update method according to the present disclosure is shown. As shown in fig. 1, the cursor position updating method includes the following steps:
In this embodiment, the executing body of the cursor position updating method may determine the displacement to be moved of the cursor according to the current attitude angle variation of the cursor control device.
The cursor manipulation device may be various devices that manipulate a cursor displayed on the display device. The cursor manipulation device may include, but is not limited to, a remote control, a smart phone, a mouse (e.g., an air mouse), and the like.
In practical applications, the executing body may change the direction and the amplitude (i.e., the operation direction and the operation amplitude of the cursor control device by the user) based on the posture of the cursor control device, and move the position of the cursor. Generally, the greater the magnitude of change in the posture of the cursor control device, the greater the magnitude of movement of the cursor.
The current attitude angle change amount may be a current attitude angle change amount of the cursor manipulation device. In some scenarios, the current pose angle change may be determined based on a difference between a current pose angle of the cursor manipulation device and a previous pose angle. The current attitude angle may be a currently determined attitude angle. The previous attitude angle may be a previously determined attitude angle. Alternatively, the previous pose angle may be the previous pose angle (i.e., the previously determined pose angle) of the cursor manipulation device.
It can be understood that the gesture angle variation and the above displacement to be moved may both represent the gesture changing direction and magnitude of the cursor control device (i.e., the operation direction and operation magnitude of the cursor control device by the user).
In some scenarios, the cursor has a preset movement step. The moving step length is the moving length of the cursor responding to the unit attitude angle variation of the cursor control device. As can be seen, the cursor can move the above-mentioned moving step length every time the cursor control device changes the attitude of the unit attitude angle variation. In this case, the execution body may use a product of the current attitude angle variation and the movement step as the displacement to be moved of the cursor.
In this embodiment, the executing body may determine the first position by offsetting the displacement to be moved from the current position of the cursor.
In some scenarios, the execution body may be configured to shift the position to be moved and displaced from the current position as the first position.
In this embodiment, the execution subject may determine the second position coordinate based on a weighted coordinate sum of the first position coordinate and the current position coordinate.
The first location coordinates may be coordinates indicating a first location. The current position coordinates may be coordinates indicating the above current position.
The weighted coordinate sum may be a sum of a weighted coordinate of the first position coordinate and a weighted coordinate of the current position coordinate. As an example, the first weight of the first position coordinate is L1, and the second weight of the above current position coordinate is L2. The first position coordinates are (a, b) and the current position coordinates are (c, d). The weighted coordinates of the first position coordinates are the coordinates determined by "L1 × (a, b)", and the weighted coordinates of the second position coordinates are the coordinates determined by "L2 × (c, d)".
Referring to the previous analysis, the first position coordinates are determined on the basis of the displacement to be moved. Therefore, the second position coordinate is determined on the basis of comprehensively considering the influence ratio of the current position coordinate and the displacement to be moved.
In some scenarios, the execution subject may use a weighted coordinate sum of the first position coordinate and the current position coordinate as the second position coordinate.
And 104, moving the cursor to a second position indicated by the second position coordinate.
In this embodiment, the executing body may move the cursor from the current position to a second position indicated by a second position coordinate.
As can be seen, in this embodiment, after the gesture of the cursor control device is changed, the cursor is not directly moved from the current position by the determined displacement to be moved, but the second position coordinate is determined based on the weighted coordinate sum of the first position coordinate and the current position coordinate, and the cursor is moved to the second position.
Referring to the foregoing analysis, the first position coordinate is determined based on the above displacement to be moved, and the above displacement to be moved may embody a posture change of the cursor control device (i.e., an operation of the cursor control device by the user). Therefore, in this embodiment, the position of the cursor can be updated by comprehensively considering the current position of the cursor and the influence ratio of the posture change of the cursor control device.
In some embodiments, the execution body may determine the current attitude angle change amount of the cursor in the following manner.
Firstly, current posture detection data of cursor control equipment are obtained.
The cursor control device may be equipped with sensors such as accelerometers, gyroscopes and magnetometers. The cursor control device can acquire attitude detection data by using the sensor. The attitude detection data may include an acceleration and an angular velocity of the cursor control device, and a magnetic induction intensity of a position where the cursor control device is located.
In some scenarios, the execution body may acquire gesture detection data from the cursor manipulation device every predetermined length of time (e.g., 10 milliseconds).
The current posture detection data may be currently acquired posture detection data of the cursor control device.
And secondly, determining the current attitude angle of the cursor control equipment according to the current attitude detection data.
Specifically, the executing body may determine the current attitude angle of the cursor control device according to the currently acquired acceleration, angular velocity, and magnetic induction.
And thirdly, taking the difference between the current attitude angle of the cursor control equipment and the previous attitude angle as the current attitude angle variation.
As can be seen, in these embodiments, the amount of change in the attitude angle of the cursor manipulation device can be determined in real time based on the attitude detection data obtained from the cursor manipulation device. Therefore, when the posture of the cursor control device changes, the displacement to be moved of the cursor can be determined in real time, and further, the cursor can timely respond to the posture change of the cursor control device.
In some embodiments, the executing body may determine the displacement of the cursor to be moved in the following manner.
Firstly, determining the moving step length of the cursor according to the current attitude angle variation.
It can be understood that the larger the moving step of the cursor, the higher the response sensitivity of the cursor. Here, the moving step length of the cursor can be reasonably determined according to the current attitude angle variation of the cursor control device.
In some scenarios, if the current attitude angle change amount is less than or equal to the angle change amount threshold, the execution main body may use the first moving step as the moving step of the cursor. If the current attitude angle variation is greater than the angle variation threshold, the execution main body may use the second moving step as the moving step of the cursor. Wherein the second moving step is larger than the first moving step.
And secondly, determining the displacement to be moved of the cursor based on the product of the current attitude angle variation and the moving step length.
In some scenarios, the execution subject may use a product of the current attitude angle variation and the movement step as the displacement to be moved of the cursor.
Therefore, in the embodiments, the displacement to be moved of the cursor is reasonably determined by comprehensively considering the attitude change amplitude of the cursor control device and the response sensitivity of the cursor.
In some embodiments, the attitude angles include azimuth and pitch. It is understood that the attitude angle change amount of the cursor control device includes an azimuth angle change amount and a pitch angle change amount.
Referring to fig. 2, in the spatial coordinate system, the azimuth angle of the cursor control device may be a rotation angle of the cursor control device around the Z-axis, and the pitch angle of the cursor control device may be a rotation angle of the cursor control device around the X-axis.
The azimuth angle may be a left-right movement angle of the cursor control device, and the pitch angle may be a up-down movement angle of the cursor control device. Therefore, the azimuth angle can reflect the posture change of the cursor control device in the horizontal direction, and the pitch angle can reflect the posture change of the cursor control device in the vertical direction.
The execution body may determine the movement step of the cursor in the following manner.
The method comprises the steps of firstly, determining the comprehensive attitude angle variation of the cursor control equipment according to the current azimuth angle variation and the current pitch angle variation of the cursor control equipment.
Regarding the manner of determining the above-mentioned integrated attitude angle variation, reference may be made to the description in other embodiments, and details are not repeated here.
The change amount of the attitude angle of the cursor control equipment and the moving step length of the cursor meet positive correlation.
And secondly, determining a moving step length corresponding to the comprehensive attitude angle variation based on the positive correlation.
In some scenarios, the execution main body may input the integrated attitude angle variation into a predetermined formula, so as to determine a movement step (i.e., a movement step of the cursor) corresponding to the integrated attitude angle variation. The predetermined formula may be various formulas for representing the positive correlation, and is not limited herein.
It can be seen that, in these embodiments, the larger the change amount of the attitude angle of the cursor manipulation device, the larger the movement step size of the cursor. Therefore, the larger the posture change of the cursor control device which can ensure the cursor response is, the higher the response sensitivity of the cursor is.
In some embodiments, the to-be-moved displacement of the cursor includes a lateral to-be-moved displacement and a longitudinal to-be-moved displacement. The execution body may determine the displacement of the cursor to be moved in the following manner.
And step T1, determining the lateral displacement to be moved of the cursor based on the product of the current azimuth angle variation of the cursor control device and the moving step length.
And step T2, determining the longitudinal displacement to be moved of the cursor based on the product of the current pitch angle variation of the cursor control device and the moving step length.
In some scenarios, the execution body may use a product of the current azimuth angle variation and the moving step as a lateral to-be-moved displacement of the cursor, and use a product of the current pitch angle variation and the moving step as a longitudinal to-be-moved displacement of the cursor.
After determining the lateral to-be-moved displacement and the longitudinal to-be-moved displacement, the execution main body may laterally offset the lateral to-be-moved displacement and longitudinally offset the longitudinal to-be-moved displacement from the current position of the cursor as the first position.
In some embodiments, the executing entity may execute steps 301 to 302 shown in fig. 3 and determine the second position coordinates according to step 303 shown in fig. 3.
In some scenarios, if the current attitude angle variation is greater than or equal to a preset angle variation threshold, the executing entity may select a larger weight as the first weight. If the current attitude angle variation is smaller than a preset angle variation threshold, the execution subject may select a smaller weight as the first weight.
The first weight and the second weight may be values in the interval of [0, 1 ].
Alternatively, the difference between 1 and the first weight is used as the second weight of the current position coordinate.
As an example, the first weight of the first position coordinate is L1, and the second weight of the current position coordinate is "1-L1". The first position coordinates are (a, b) and the current position coordinates are (c, d). The weighted coordinates of the first position coordinates are the coordinates determined by "L1 × (a, b)", and the weighted coordinates of the second position coordinates are the coordinates determined by "(1-L1) × (c, d)".
In some scenarios, the execution subject may use a weighted coordinate sum of the first position coordinate and the current position coordinate as the second position coordinate.
Referring to the foregoing analysis, the current attitude angle variation may represent an attitude change of the cursor manipulation device. It can be seen that in these embodiments, a first weight for the first location coordinates and a second weight for the current location described above can be determined based on a change in the pose of the cursor manipulation device. Therefore, the influence proportion of the current position of the cursor and the posture change of the cursor control device can be reasonably determined.
In some embodiments, the execution subject may determine the first weight according to a process shown in fig. 4, which includes the following steps.
In some scenarios, the executing body may use an average of the current azimuth angle variation and the current pitch angle variation as a comprehensive attitude angle variation of the cursor control device.
It can be understood that the posture changes of the cursor control device in the horizontal direction and the vertical direction can be comprehensively embodied by synthesizing the posture angle variation.
In step 403, if the integrated attitude angle variation is smaller than the preset angle threshold, a first weight is selected from the second numerical interval.
The values in the second interval are less than or equal to the values in the first interval.
As can be seen, in these embodiments, the first weight and the second weight are determined by comprehensively considering the magnitude of the posture change of the cursor control device in the horizontal direction and the vertical direction (i.e., the magnitude of the operation of the cursor control device by the user in the horizontal direction and the vertical direction).
It is easy to find that if the integrated attitude angle variation of the cursor control device is large, the first weight of the first position coordinate is also large. If the comprehensive attitude angle change amount of the cursor control device is smaller, the first weight of the first position coordinate is also smaller. Therefore, if the posture change range of the cursor control device is large, the influence proportion occupied by the posture change of the cursor control device is large. If the gesture change amplitude of the cursor control device is smaller, the influence proportion occupied by the gesture change of the cursor control device is smaller. Thus, the cursor can respond almost negligibly to small changes in the pose of the cursor manipulation device.
As an example, in the course of a user moving a cursor from position a to position D through the cursor manipulation device, the cursor manipulation device makes two consecutive small changes in posture followed by a large change in posture. Referring to FIG. 5A, if the cursor changes in response to any gesture of the cursor manipulation device, the cursor moves in sequence from position A to position B, C, D. At this time, the cursor may be jumped on the display screen in a messy manner. This phenomenon is more prominent particularly when the response sensitivity of the cursor is high. Referring to FIG. 5B, if the cursor ignores small changes in pose in response to the cursor manipulation device, the cursor moves directly from position A to position D. At this time, smooth movement of the cursor on the display screen can be achieved.
In some embodiments, the execution body may determine the integrated attitude angle change amount of the cursor manipulation device in the following manner.
First, a square root result of a sum of a square of the current azimuth angle variation and a square of the current pitch angle variation is determined.
And secondly, determining the variation of the comprehensive attitude angle according to the square root result value.
In some scenarios, the execution subject may determine the square root result as a combined attitude angle change of the cursor control device. As an example, the current azimuth angle variation is m, and the current pitch angle variation is n. The execution body can be
The resulting value of (2) is used as the integrated attitude angle variation.
In some embodiments, the coordinates may include an abscissa and an ordinate. The execution body may determine the second position coordinates in the following manner.
Step S1, determining a second position abscissa based on a first weighted sum of the first position abscissa and the current position abscissa using the first weight and the second weight.
Step S2, determining a second position ordinate based on a second weighted sum of the first position ordinate and the current position ordinate using the first weight and the second weight.
As an example, the first weight of the first position coordinate is L1, and the second weight of the above current position coordinate is L2. The first position coordinates are (a, b) and the current position coordinates are (c, d). The first weighted sum is "L1 × a + L2 × c", and the second weighted sum is "L1 × b + L2 × d".
In some scenarios, the execution subject may use the first weighted sum as a second location abscissa and the second weighted sum as a second location ordinate. Referring to the above example, after the posture of the cursor manipulation device is changed, the execution body may move the cursor from the current position indicated by the coordinates (c, d) to the second position indicated by the coordinates [ (L1 × a + L2 × c), (L1 × b + L2 × d) ].
