Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0013] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the presence of the features declared thereafter, but does not exclude the addition of other features.

[0014] Referring to Figure 1 As shown in the flowchart of a perspective control method for X86 cloud applications, the method is applied to a mobile terminal and includes the following steps: S10, obtaining posture data of the mobile terminal; In the present embodiment, it should be noted that the posture data of the mobile terminal can be collected using a gyroscope of the mobile terminal, or the results of the optimized posture data collected by the gyroscope can be obtained using a related module provided by the system of the mobile terminal as the posture data of the mobile terminal, such as when the mobile terminal is an iPhone or iPad, the attitude object of the CMDeviceMotion module (i.e. the sensor framework module provided by the iOS system) callback can be used to obtain the posture data of the mobile terminal.

[0015] S11, determining intermediate data according to the posture data, and sending the intermediate data to a cloud server, so that the cloud server determines offset accumulation value offsetY and offset accumulation value offsetX of the mouse in the height direction and the width direction on the cloud application picture of the cloud server according to the intermediate data, and sends the offset accumulation value offsetY and the offset accumulation value offsetX to the system of the cloud server, so as to control the perspective of the X86 cloud application, wherein the intermediate data is the source data or the intermediate result or the target result in the process of obtaining the offset accumulation value offsetY and the offset accumulation value offsetX from the posture data, and the process of obtaining the offset accumulation value offsetY and the offset accumulation value offsetX from the posture data includes: obtaining offset diffY and offset diffX in the height direction and the width direction of the mouse on the cloud application picture of the cloud server according to the posture data; calculating the offset accumulation value offsetY and the offset accumulation value offsetX according to the offset diffY and the offset diffX.

[0016] It should be noted that the purpose of the scheme is that the cloud server sends the offset accumulation value offsetY and the offset accumulation value offsetX to the system of the cloud server to control the view angle of the X86 cloud application. Based on this purpose, the source data or the intermediate result or the target result (i.e., the intermediate data) in the process of obtaining the offset accumulation value offsetY and the offset accumulation value offsetX from the attitude data can be sent to the cloud server. After receiving the intermediate data, the cloud server can determine the offset accumulation value offsetY and the offset accumulation value offsetX based on the intermediate data. That is, the operation process of obtaining the offset accumulation value offsetY and the offset accumulation value offsetX from the attitude data in the embodiment can be independently executed by the mobile terminal, or independently executed by the cloud server, or cooperatively executed by the mobile terminal and the cloud server.

[0017] The method for controlling the view angle of the X86 cloud application provided in the embodiment of the application comprises the following steps: obtaining attitude data of a mobile terminal; determining intermediate data from the attitude data; and sending the intermediate data to a cloud server, so that the cloud server determines offset accumulation values of a mouse in a height direction and a width direction of a cloud application picture of the cloud server from the intermediate data, and sends the offset accumulation values offsetY and offsetX to a system of the cloud server. That is, the attitude data of the mobile terminal is converted into the offset accumulation values of the mouse that can be recognized by the system of the cloud server and can control the view angle of the X86 cloud application, so as to control the view angle of the X86 cloud application. When a user uses the X86 cloud application, the user only needs to adjust the attitude of the mobile terminal to control the view angle, without the need of a third hand to control. Thus, the view angle of the X86 cloud application can be controlled.

[0018] On the basis of the method embodiment, the offset diffY in the height direction and the offset diffX in the width direction of the mouse on the cloud application picture of the cloud server obtained from the attitude data can comprise the following steps: determining a rotation angle roll of the mobile terminal around an X axis of the reference coordinate system and a rotation angle pitch of the mobile terminal around a Y axis of the reference coordinate system from the attitude data; mapping the rotation angle roll to a Y axis coordinate point Y1 on the mobile terminal screen and mapping the rotation angle pitch to an X axis coordinate point X1 on the mobile terminal screen if the mobile terminal screen is horizontal, or mapping the rotation angle pitch to the Y axis coordinate point Y1 on the mobile terminal screen and mapping the rotation angle roll to the X axis coordinate point X1 on the mobile terminal screen if the mobile terminal screen is vertical; calculating the offset diffY from the Y axis coordinate point Y1 and calculating the offset diffX from the X axis coordinate point X1.

[0019] In this embodiment, it should be noted that the rotation angle roll of the mobile terminal around the X axis of the reference coordinate system and the rotation angle pitch of the mobile terminal around the Y axis of the reference coordinate system can be obtained from the attitude data, and the rotation angle roll and the rotation angle pitch are mapped to the coordinate points on the corresponding coordinate axes on the screen of the mobile terminal. Specifically, if the screen of the mobile terminal is horizontal, the cloud application picture is displayed horizontally, the rotation angle roll needs to be mapped to the Y axis coordinate point Y1 on the screen of the mobile terminal, and the rotation angle pitch needs to be mapped to the X axis coordinate point X1 on the screen of the mobile terminal. If the screen of the mobile terminal is vertical, the cloud application picture is displayed horizontally, the rotation angle pitch needs to be mapped to the Y axis coordinate point Y1 on the screen of the mobile terminal, and the rotation angle roll needs to be mapped to the X axis coordinate point X1 on the screen of the mobile terminal. When the coordinate points on the coordinate axes are mapped, a linear mapping manner or a nonlinear mapping manner can be used. The linear mapping manner refers to the value mapped by the rotation angle in the case that the maximum range of the rotation angle is uniformly mapped to [0, L]; the nonlinear mapping manner refers to the value mapped by the rotation angle in the case that the maximum range of the rotation angle is non-uniformly mapped to [0, L], and L is the height screenHeight or the width screenWidth of the cloud application picture of the mobile terminal. When the screen of the mobile terminal is horizontal, the cloud application picture is displayed horizontally: if the rotation angle is roll, the maximum range of the rotation angle can be [−π, π] (the rotation angle can be negative when the mobile terminal is reversed to the direction of the handheld user, and the rotation angle can be positive when the mobile terminal is reversed to the direction facing the handheld user), and L is screenHeight; if the rotation angle is pitch, the maximum range of the rotation angle can be [−π / 2, π / 2] (the rotation angle can be positive when the mobile terminal is reversed to the left direction of the handheld user, and the rotation angle can be negative when the mobile terminal is reversed to the right direction of the handheld user), and L is screenWidth. When the screen of the mobile terminal is vertical, the cloud application picture is displayed horizontally: if the rotation angle is roll, the maximum range of the rotation angle can be [−π / 2, π / 2] (the rotation angle can be negative when the mobile terminal is reversed to the direction of the handheld user, and the rotation angle can be positive when the mobile terminal is reversed to the direction facing the handheld user), and L is screenWidth; if the rotation angle is pitch, the maximum range of the rotation angle can be [−π, π] (the rotation angle can be negative when the mobile terminal is reversed to the left direction of the handheld user, and the rotation angle can be positive when the mobile terminal is reversed to the right direction of the handheld user), and L is screenHeight.

[0020] If the linear mapping manner is used, the calculation formula of mapping the rotation angle roll to the Y axis coordinate point Y1 on the screen of the mobile terminal can be: Y1= (roll + π) / (2 x π) x screenHeight (1) wherein, screenHeight represents the height of the cloud application picture of the mobile terminal; The calculation formula of the X-axis coordinate point X1 on the mobile terminal screen mapped by the rotation angle pitch can be: X1= (pitch + π / 2) / π x screenWidth (2) wherein, screenWidth represents the width of the cloud application picture of the mobile terminal.

[0021] If the linear mapping is adopted, the calculation formula of the Y-axis coordinate point Y1 on the mobile terminal screen mapped by the rotation angle pitch can be the formula obtained by replacing roll in formula (1) with pitch; the calculation formula of the X-axis coordinate point X1 on the mobile terminal screen mapped by the rotation angle roll can be the formula obtained by replacing pitch in formula (2) with roll.

[0022] The maximum range of the rotation angle can be segmented, and each segment is uniformly mapped to a subset of [0, L], and the length of the subset mapped by each segment is not completely the same. For example, the maximum range of the rotation angle roll is [-π, π], and L is screenHeight. Then, [-π, 0] can be uniformly mapped to [0, L / 4], and (0, π] can be uniformly mapped to (L / 4, L].

[0023] On the basis of the foregoing method embodiment, the offset diffY calculated according to the Y-axis coordinate point Y1 can include: the Y-axis coordinate point Y1 is mapped to the Y-axis coordinate point Y2 on the cloud application picture of the cloud server, and the offset diffY is calculated according to the Y-axis coordinate point Y2; or the Y-axis coordinate point offset is calculated according to the Y-axis coordinate point Y1, and the Y-axis coordinate point offset is mapped to the offset diffY; The offset diffX calculated according to the X-axis coordinate point X1 can include: the X-axis coordinate point X1 is mapped to the X-axis coordinate point X2 on the cloud application picture of the cloud server, and the offset diffX is calculated according to the X-axis coordinate point X2; or the X-axis coordinate point offset is calculated according to the X-axis coordinate point X1, and the X-axis coordinate point offset is mapped to the offset diffX.

[0024] It should be noted that the ratio of the width and height of the cloud application picture of the mobile terminal is the same as that of the cloud server, and cWidth and cHeight are the width and height of the cloud application picture of the cloud server. Y2=Y1 / screenHeight×cHeight, X2=X1 / screenWidth×cWidth. The offset diffY can be the product of the difference between the current Y2 and the last Y2 and the offset sensitivity, and the offset diffX can be the product of the difference between the current X2 and the last X2 and the offset sensitivity. The offset sensitivity can be set as needed, such as 3.

[0025] The calculation formula of the Y-axis coordinate point offset according to the Y-axis coordinate point Y1 can be: tiffY=(Y1-Y1`)×gyroSensitivityY (3) Wherein, tiffY represents the Y-axis coordinate point offset, Y1 and Y1` represent the current Y-axis coordinate point Y1 and the last Y-axis coordinate point Y1 respectively, and gyroSensitivityY represents the offset sensitivity. diffY=tiffY / screenHeight×cHeight.

[0026] The calculation formula of the X-axis coordinate point offset according to the X-axis coordinate point X1 can be consistent with formula (3), which will not be repeated here. diffX=tiffX / screenWidth×cWidth.

[0027] On the basis of the foregoing method embodiment, the calculation formula of the Y-axis coordinate point offset according to the Y-axis coordinate point Y1 can be: tiffY=(α×f(liffY) / T+(1-α)×liffY`)×sensitivity, Wherein, f(liffY)=sign(liffY)×|liffY| γ , The formula for calculating the X-axis coordinate point offset according to the X-axis coordinate point X1 can be consistent with the formula for calculating the Y-axis coordinate point offset according to the Y-axis coordinate point Y1. Details are not repeated here.

[0028] On the basis of the foregoing method embodiment, the calculating the offset accumulation value offsetY and the offset accumulation value offsetX according to the offset diffY and the offset diffX can include: When the absolute value of the offset diffY is greater than a first threshold or the absolute value of the offset diffX is greater than a second threshold, the offset accumulation value offsetY is calculated according to the offset diffY, and the offset accumulation value offsetX is calculated according to the offset diffX.

[0029] In this embodiment, it should be noted that only when the absolute value of the latest offset diffY is greater than the first threshold or the absolute value of the latest offset diffX is greater than the second threshold, the latest offset diffY is added to the existing offsetY, and the latest offset diffX is added to the existing offsetX; otherwise, the latest offset diffY / diffX is not added to the existing offsetY / offsetX, in which case the offsetY and the offsetX do not change, and the cloud server will not send the offsetY and the offsetX to the system of the cloud server. The offsetY and the offsetX can be initially set to 0. The first threshold = θ x π / 180 x screenHeight, and the second threshold = σ x π / 180 x screenWidth. θ and σ can be set as needed, for example, to 1°.
