In the method, when distances between the remote control device and the screen device are different or pointing directions of the remote control device are different, a movement distance of the cursor on the screen device is still the same for the same angle of deflection of the remote control device. The user can accurately control a movement precision of the cursor, and the use experience of the user is improved.

[0148] The software system of the remote control device 100 can adopt a layered architecture. Embodiments of the present application take an Android system with a layered architecture as an example to illustrate the software structure of the remote control device 100.

[0149] FIG. 1D FIG. 1 is a software structure block diagram of the remote control device 100 according to an embodiment of the present application.

[0150] The layered architecture divides software into several layers, each of which has a clear role and division of labor. Layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom, the application layer, the application framework layer, the Android runtime and system library, and the kernel layer.

[0151] The application layer can include a series of application packages.

[0152] As shown in FIG. 1, the application packages can include WLAN, Bluetooth, and other applications. FIG. 1D

[0153] The application framework layer provides application programming interfaces (APIs) and programming frameworks for the applications of the application layer. The application framework layer includes some pre-defined functions.

[0154] As shown in FIG. 1, the application framework layer can include a window manager, a content provider, and the like. FIG. 1D

[0162] The kernel layer is a layer between hardware and software. The kernel layer at least contains a display driver and a sensor driver.

[0163] The position relationship between the remote control device and the smart TV screen is further described by taking the smart TV screen as an example in combination with the drawings.

[0164] When the user uses the remote control device to control the smart TV, the user can operate the keys on the remote control device to switch the remote control device to the mouse mode. As shown in the scene schematic diagram, after the remote control device is switched to the mouse mode, the remote control device can transmit the cursor position information to the smart TV, and the smart TV can display the cursor at the position corresponding to the cursor position information in the smart TV screen according to the cursor position information. FIG. 2 As shown in the scene diagram, the distance between the remote control device and the smart TV screen is L1, the user holds the remote control device to make the pointing direction of the remote control device deviate from the vertical direction of the smart TV screen by an angle a in the horizontal plane, and the distance that the cursor moves in the smart TV screen is L2. As shown in the scene diagram, the distance between the remote control device and the smart TV screen is L3, where L3 is greater than L1, the user holds the remote control device to make the pointing direction of the remote control device deviate from the vertical direction of the smart TV screen by an angle a in the horizontal plane, and the distance that the cursor moves in the smart TV screen is L4. That is, when the remote control device is deviated by the same angle, the distance that the cursor moves in the smart TV screen is not the same. That is, when the remote control device is deviated by the same angle, the greater the distance between the remote control device and the smart TV screen, the greater the distance that the cursor moves in the smart TV screen; the smaller the distance between the remote control device and the smart TV screen, the smaller the distance that the cursor moves in the smart TV screen. This will make the user's moving accuracy of the cursor be affected by the distance between the remote control device and the smart TV screen when the user uses the remote control device, and the user cannot accurately control the moving accuracy of the cursor, which reduces the user's use experience.

[0165] FIG. 3A FIG. 3B

[0166] As shown in the scene diagram, the distance between the remote control device and the smart TV screen is L1, the user holds the remote control device to make the pointing direction of the remote control device deviate from the vertical direction of the smart TV screen by an angle a in the horizontal plane, and the distance that the cursor moves in the smart TV screen is L2. As shown in the scene diagram, the distance between the remote control device and the smart TV screen is L3, where L3 is greater than L1, the user holds the remote control device to make the pointing direction of the remote control device deviate from the vertical direction of the smart TV screen by an angle a in the horizontal plane, and the distance that the cursor moves in the smart TV screen is L4. That is, when the remote control device is deviated by the same angle, the distance that the cursor moves in the smart TV screen is not the same. That is, when the remote control device is deviated by the same angle, the greater the distance between the remote control device and the smart TV screen, the greater the distance that the cursor moves in the smart TV screen; the smaller the distance between the remote control device and the smart TV screen, the smaller the distance that the cursor moves in the smart TV screen. This will make the user's moving accuracy of the cursor be affected by the distance between the remote control device and the smart TV screen when the user uses the remote control device, and the user cannot accurately control the moving accuracy of the cursor, which reduces the user's use experience. FIG. 4A ​​​In the scene diagram shown, the distance between the remote control and the smart TV screen is L1. The user holds the remote control so that its pointing direction starts perpendicular to the smart TV screen (i.e., the angle between the remote control's pointing direction and the horizontal plane is 0), and deflects by an angle 'a' on the horizontal plane. The distance the cursor moves on the smart TV screen is L2. FIG. 4B In the scenario shown, the distance between the remote control and the smart TV screen is L1. The user holds the remote control, starting with an angle b between the remote and the horizontal plane, and then deflects the remote by an angle a on the horizontal plane. However, the distance the cursor moves on the smart TV screen, L5, is greater than L2. This means that when the remote control's pointing direction is different, the distance the cursor moves on the smart TV screen is not the same when the remote control is deflected by the same angle. Specifically, the larger the angle between the remote control's pointing direction and the horizontal plane, the greater the distance the cursor moves on the smart TV screen; conversely, the smaller the angle, the smaller the distance. This means that the cursor's movement accuracy is affected by the remote control's pointing direction, making it difficult for the user to accurately control the cursor's movement and reducing the user experience.

[0167] The following embodiments can all be implemented in electronic devices (such as remote control device 100) with the above-described hardware structure. The following embodiments will take remote control device 100 as an example and describe in detail the cursor position determination method provided by the embodiments of this application with reference to the accompanying drawings.

[0168] FIG. 5 An exemplary flowchart of a cursor position determination method provided in an embodiment of this application is illustrated. The cursor position determination method may include:

[0169] S501, when the pointing direction of the remote control device deflects, the remote control device determines the first deflection angle of the pointing direction of the remote control device relative to the first reference line.

[0170] Before the remote control device executes S501 as described above, the remote control device receives a first operation, wherein the first operation includes an operation by which the user deflects the pointing direction of the remote control device. The deflection of the pointing direction of the remote control device includes a horizontal deflection and / or a vertical deflection.

[0171] To facilitate defining the location of remote-controlled devices, a geodetic reference coordinate system can be established, such as... FIG. 6A As shown, one way to define a geodetic reference coordinate system is as follows: the positive x-axis is tangent to the ground at the current location of the remote control device, pointing directly east; the positive y-axis is also tangent to this ground, pointing towards the magnetic north pole; the xOy plane formed by the x and y axes is the horizontal plane; the positive z-axis is perpendicular to the horizontal plane and points towards the sky. FIG. 6AThe geodetic reference coordinate system shown is applied in scenarios involving remote control devices and smart TVs, such as... FIG. 6B As shown. In FIG. 6B The scenario shown illustrates several possible implementations of the positional relationship between the remote control device and the smart TV screen.

[0172] Implementation method one, in the geodetic coordinate system, FIG. 6B The first plane of the remote control device is parallel to the horizontal plane, where the first plane is the plane where the buttons on the remote control device are located. FIG. 6B The smart TV screen is parallel to the xOz plane formed by the x-axis and z-axis.

[0173] The statement that the first plane of the remote control device is parallel to the horizontal plane can be understood as follows: the angle between the first plane of the remote control device and the horizontal plane is 0, or the angle between the first plane of the remote control device and the horizontal plane is θ, where θ is greater than 0 and less than a first angle threshold. This first angle threshold can be set according to actual needs, and this article does not impose any restrictions on it.

[0174] The parallelism of the smart TV screen to the xOz plane can be understood as follows: the angle between the smart TV screen and the xOz plane is 0, or the angle between the smart TV screen and the xOz plane is θ, where θ is greater than 0 and less than a first angle threshold. This first angle threshold can be set according to actual needs, and this article does not impose any restrictions on it.

[0175] In this first implementation method, FIG. 6B The scene shown is a top view (i.e., a view along the negative z-axis) in the geodetic coordinate system, as shown below. FIG. 7A As shown, FIG. 6B The left view corresponding to the scene shown (i.e., the view seen along the negative x-axis) is as follows: FIG. 7B As shown.

[0176] When the remote control is turned on and its head is pointed at the smart TV screen, a cursor will appear on the screen. The cursor's location indicates the area on the smart TV screen that the remote control can control. For example, in a... FIG. 7A The top view shown and FIG. 7B In the left view shown, the first plane of the remote control device is parallel to the horizontal plane (i.e., the xOy plane in the geodetic coordinate system), and the head of the remote control device points to position 1 on the smart TV screen. The cursor corresponding to the remote control device is displayed at position 1 on the smart TV screen. The user can hold the remote control device and adjust its pointing direction to change the position on the smart TV screen that needs to be controlled. Adjusting the pointing direction of the remote control device includes horizontal deflection and / or vertical deflection. Three possible implementation methods are provided below.

[0177] In a first possible implementation, the remote control device is deflected in the horizontal direction, i.e. the tail of the remote control device is fixed, and the head of the remote control device is deflected by an angle a (where a is greater than 0) along the positive direction of the x-axis in the horizontal plane, as shown in FIG. 7A and FIG. 7B. FIG. 7C As shown in the top view and the left view of FIG. 7D, the cursor corresponding to the deflected remote control device is displayed at position 2 in the smart TV screen. Based on the deflection of the remote control device, the cursor is deflected by an angle a along the positive direction of the x-axis in the horizontal plane. FIG. 7A , FIG. 7B , FIG. 7C , FIG. 7D It can be seen that the head of the remote control device is deflected by an angle a along the positive direction of the x-axis in the horizontal plane, and the cursor in the smart TV screen is also moved by a certain distance along the positive direction of the x-axis. In some embodiments, the tail of the remote control device can also be fixed, and the head of the remote control device can be deflected by an angle a along the negative direction of the x-axis in the horizontal plane, which is not described herein.

[0178] In a second possible implementation, the remote control device is deflected in the vertical direction, i.e. the tail of the remote control device is fixed, and the head of the remote control device is deflected by an angle b (where b is greater than 0) along the positive direction of the z-axis in the yOz plane formed by the y-axis and the z-axis, as shown in FIG. 7E and FIG. 7F. FIG. 7E As shown in the top view and the left view of FIG. 7F, the cursor corresponding to the deflected remote control device is displayed at position 3 in the smart TV screen. Based on the deflection of the remote control device, the cursor is deflected by an angle b along the positive direction of the z-axis in the yOz plane. FIG. 7A , FIG. 7B , FIG. 7E , FIG. 7F It can be seen that the head of the remote control device is deflected by an angle b along the positive direction of the z-axis in the yOz plane, and the cursor in the smart TV screen is also moved by a certain distance along the positive direction of the z-axis. In some embodiments, the tail of the remote control device can also be fixed, and the head of the remote control device can be deflected by an angle b along the negative direction of the z-axis in the yOz plane, which is not described herein.

[0179] In a third possible implementation, the remote control device is deflected in the horizontal direction and the vertical direction, i.e. the tail of the remote control device is fixed, the head of the remote control device is deflected by an angle a along the positive direction of the x-axis in the horizontal plane, and the head of the remote control device is deflected by an angle b along the positive direction of the z-axis in the yOz plane formed by the y-axis and the z-axis (where a is greater than 0, and b is greater than 0), as shown in FIG. 7G and FIG. 7H. FIG. 7G As shown in the top view and the left view of FIG. 7H, the cursor corresponding to the deflected remote control device is displayed at position 4 in the smart TV screen. Based on the deflection of the remote control device, the cursor is deflected by an angle a along the positive direction of the x-axis in the horizontal plane, and the cursor is deflected by an angle b along the positive direction of the z-axis in the yOz plane. FIG. 7A , FIG. 7B , FIG. 7G , FIG. 7HAs can be seen, rotating the head of the remote control device by an angle 'a' along the positive x-axis in the horizontal plane will move the cursor a certain distance along the positive x-axis on the smart TV screen. Similarly, rotating the head of the remote control device by an angle 'b' along the positive z-axis in the yOz plane will also move the cursor a certain distance along the positive z-axis on the smart TV screen. In some embodiments, the tail of the remote control device can be fixed, and the head of the remote control device can be rotated by an angle 'a' along the negative x-axis in the horizontal plane; simultaneously, the tail of the remote control device can be fixed, and the head of the remote control device can be rotated by an angle 'b' along the negative z-axis in the yOz plane. These details will not be elaborated upon here.

[0180] Implementation method two, in the geodetic coordinate system, FIG. 6B The first plane of the remote control device is parallel to the second plane, where the angle between the second plane and the horizontal plane is angle c. The first plane is the plane where the buttons on the remote control device are located, and angle c is greater than 0 and less than 180 degrees. FIG. 6B The smart TV screen is parallel to the xOz plane formed by the x-axis and z-axis.

[0181] In this second implementation method, FIG. 6B The scene shown is a top view (i.e., a view along the negative z-axis) in the geodetic coordinate system, as shown below. FIG. 8A As shown, FIG. 6B The left view corresponding to the scene shown (i.e., the view seen along the negative x-axis) is as follows: FIG. 8B As shown.

[0182] When the remote control is turned on and its head is pointed at the smart TV screen, a cursor will appear on the screen. The cursor's location indicates the area on the smart TV screen that the remote control can control. For example, in a... FIG. 8A The top view shown and FIG. 8B In the left view shown, the angle between the first plane of the remote control device and the horizontal plane is angle c, and the head of the remote control device points to position 5 on the smart TV screen. The cursor corresponding to the remote control device is displayed at position 5 on the smart TV screen. The user can hold the remote control device and adjust its pointing direction to change the position on the smart TV screen that needs to be controlled. Adjusting the pointing direction of the remote control device includes horizontal deflection and / or vertical deflection. Three possible implementation methods are provided below.

[0183] In a first possible implementation, the remote control device is deflected horizontally, that is, the tail of the remote control device is kept stationary, and the head of the remote control device is deflected by an angle α (where α is greater than 0) along the positive x-axis in the second plane. FIG. 8C As shown in the top view and 8D left view, after deflection, the cursor corresponding to the remote control device is displayed at position 6 on the smart TV screen. Based onFIG. 8A 、 FIG. 8B 、 FIG. 8C 、 FIG. 8D It can be seen that the cursor in the smart TV screen will also move a certain distance along the positive direction of the x axis when the head of the remote control device is deflected by an angle a along the positive direction of the x axis on the second plane. In some embodiments, the tail of the remote control device can also be fixed, and the head of the remote control device is deflected by an angle a along the negative direction of the x axis on the second plane, which is not described herein.

[0184] In a second possible implementation, the remote control device is deflected in the vertical direction, that is, the tail of the remote control device is fixed, and the head of the remote control device is deflected by an angle b (where b is greater than 0) along the positive direction of the z axis on the yOz plane formed by the y axis and the z axis, as shown in the top view and the left view of FIG. 8F. FIG. 8E After deflection, the remote control device corresponds to the cursor displayed at position 7 in the smart TV screen, as shown in the top view and the left view of FIG. 8F. Based on the deflection of the remote control device, the smart TV screen displays the cursor at position 7. FIG. 8A 、 FIG. 8B 、 FIG. 8E 、 FIG. 8F It can be seen that the cursor in the smart TV screen will also move a certain distance along the positive direction of the z axis when the head of the remote control device is deflected by an angle b along the positive direction of the z axis on the yOz plane. In some embodiments, the tail of the remote control device can also be fixed, and the head of the remote control device is rotated by an angle b along the negative direction of the z axis on the yOz plane, which is not described herein.

[0185] In a third possible implementation, the remote control device is deflected in the horizontal direction and the vertical direction at the same time, that is, the tail of the remote control device is fixed, and the head of the remote control device is deflected by an angle a along the positive direction of the x axis on the second plane, and the head of the remote control device is deflected by an angle b along the positive direction of the z axis on the yOz plane formed by the y axis and the z axis (where a is greater than 0, and b is greater than 0), as shown in the top view and the left view of FIG. 8H. FIG. 8G After deflection, the remote control device corresponds to the cursor displayed at position 8 in the smart TV screen, as shown in the top view and the left view of FIG. 8H. Based on the deflection of the remote control device, the smart TV screen displays the cursor at position 8. FIG. 8A 、 FIG. 8B 、 FIG. 8G 、 FIG. 8HIt can be seen that, when the head of the remote control device is deflected by an angle a along the positive direction of the x axis on the second plane, the cursor in the smart TV screen will also move a certain distance along the positive direction of the x axis, and when the head of the remote control device is deflected by an angle b along the positive direction of the z axis on the yOz plane, the cursor in the smart TV screen will also move a certain distance along the positive direction of the z axis. In some embodiments, the tail of the remote control device can also be fixed, the head of the remote control device is deflected by an angle a along the negative direction of the x axis on the second plane, and meanwhile, the tail of the remote control device can also be fixed, the head of the remote control device is rotated by an angle b along the negative direction of the z axis on the yOz plane, which will not be described herein.

[0186] In the embodiments of the present application, the first reference line is determined based on the position of the remote control device and the center position of the screen device. The position of the remote control device can be the center position of the head of the remote control device (which can be referred to as the head position of the remote control device, for example, as shown in FIG. 9 ), or the center position of the remote control device (which can be referred to as the center position of the remote control device, for example, as shown in FIG. 10 ), or determined in other ways, which will not be limited herein.

[0187] In a possible implementation, the line connecting the position of the remote control device and the center position of the screen device is taken as the first reference line. The position of the remote control device is not fixed, and the user can adjust the position of the remote control device at any time. In the case that the screen device is fixed, the first reference line changes with the change of the position of the remote control device. Taking the screen device as a smart TV screen for example, as shown in FIG. 11 , the position of the remote control device is located in front of the center position of the screen, and then the first reference line is perpendicular to the plane on which the smart TV screen is located, that is, the first reference line is the median line of the smart TV screen. For example FIG. 12 , the position of the remote control device is not located in front of the center position of the screen, and then the first reference line has a certain angle with the median line of the smart TV screen.

[0188] As shown in FIG. 13A and FIG. 13B , the pointing direction of the remote control device can be regarded as a straight line parallel to the long edge line of the remote control device, with the position of the remote control device as the starting point. The pointing direction of the remote control device is affected by the position of the remote control device.

[0189] The first reference line is not affected by the pointing direction of the remote control device. The following examples are all taken with the screen device as a smart TV screen.

[0190] As shown in FIG. 14A , in the case that the position of the remote control device is unchanged and the pointing direction of the remote control device changes, the first reference line is unchanged, and the first reference line is not affected by the pointing direction of the remote control device. As shown in FIG. 14BAs shown, when the position of the remote control device changes but its pointing direction remains the same, the first reference line changes with the position of the remote control device. FIG. 14C As shown, when the position of the remote control device changes or the pointing direction of the remote control device changes, the first reference line changes with the position of the remote control device and is not affected by the pointing direction of the remote control device.

[0191] The first reference line and the pointing direction of the remote control device can have a variety of possible relationships, all of which are illustrated below using a smart TV screen as an example.

[0192] by FIG. 15A In the scenario shown, the remote control is positioned directly in front of the center of the smart TV screen, and the direction the remote control is pointing is perpendicular to the smart TV screen. FIG. 15B for FIG. 15A The corresponding top view, FIG. 15C for FIG. 15A The corresponding left view, combined with FIG. 15B and FIG. 15C It can be seen that the pointing direction of the remote control device coincides with the first reference line.

[0193] by FIG. 16A In the scenario shown, the remote control is positioned directly in front of the center of the smart TV screen, and the direction the remote control is pointing is not perpendicular to the smart TV screen. FIG. 16B for FIG. 16A The corresponding top view, FIG. 16C for FIG. 16A The corresponding left view, combined with FIG. 16B and FIG. 16C It can be seen that the pointing direction of the remote control device does not coincide with the first reference line.

[0194] by FIG. 17A In the scenario shown, the remote control is not located directly in front of the center of the smart TV screen, and the direction the remote control is pointing is not perpendicular to the smart TV screen. FIG. 17B for FIG. 17A The corresponding top view, FIG. 17C for FIG. 17A The corresponding left view, combined with FIG. 17B and FIG. 17C It can be seen that the pointing direction of the remote control device does not coincide with the first reference line.

[0195] In this embodiment of the application, the determination of the first deflection angle of the pointing direction of the remote control device relative to the first reference line may include the following two possible implementation methods:

[0196] In a first possible implementation, determining the first deflection angle of the pointing direction of the remote control device relative to the first reference line may include the following steps:

[0197] In one possible implementation, the angle between the pointing direction of the remote control device and a first reference plane is used as the first horizontal deflection angle, wherein the first reference plane is a plane perpendicular to the horizontal plane and includes a first reference line. The angle between the pointing direction of the remote control device and a second reference plane is used as the first vertical deflection angle, wherein the second reference plane is a plane parallel to the horizontal plane and includes the first reference line. Finally, the obtained first horizontal deflection angle and first vertical deflection angle are used as the first deflection angle.

[0198] It should be understood that the method for calculating the angle between the pointing direction of the remote control device and the first reference plane, or the angle between the pointing direction of the remote control device and the second reference plane, can refer to the method for calculating the angle between a line and a plane in geometry, and will not be elaborated here.

Therefore, in the case of a fixed screen device, the second reference line changes with the position of the remote control device.

[0205] The following examples are all based on the screen device being a smart TV screen.

[0206] For example FIG. 21A As shown, the position of the remote control device is located in front of the center of the smart TV screen, and the determined second reference line coincides with the first reference line.

[0210] In the embodiments of the present application, the second deflection angle includes a second horizontal deflection angle and / or a second vertical deflection angle.

[0211] In the embodiments of the present application, determining the second horizontal deflection angle and the second vertical deflection angle can include the following two possible implementation manners:

[0212] In one possible implementation manner, an angle between the second reference line and a third reference surface is taken as the second horizontal deflection angle, where the third reference surface is a plane perpendicular to the horizontal plane and including the first reference line. An angle between the second reference line and a fourth reference surface is taken as the second vertical deflection angle, where the fourth reference surface is a plane parallel to the horizontal plane and including the first reference line. Finally, the obtained second horizontal deflection angle and the second vertical deflection angle are taken as the second deflection angle.

[0213] It should be understood that the method for calculating the angle between the second reference line and the third reference surface, or the angle between the second reference line and the fourth reference surface can refer to the calculation method of the angle between a straight line and a plane in geometry, which is not described herein.

[0214] In another possible implementation manner, a length of the second reference line is taken as a first distance, where the first distance is a distance between the position of the remote control device and the center position of the screen device in the y-axis direction. A distance between the end point of the second reference line and the center position of the screen device in the x-axis direction is taken as a second distance, where the second distance is a distance between the position of the remote control device and the center position of the screen device in the x-axis direction. A distance between the end point of the second reference line and the center position of the screen device in the z-axis direction is taken as a third distance, where the third distance is a distance between the position of the remote control device and the center position of the screen device in the z-axis direction.

[0215] After the first distance, the second distance and the third distance are determined, the second horizontal deflection angle and the second vertical deflection angle can be determined according to the arctangent function, where the second horizontal deflection angle = arctan (second distance / first distance), and the second vertical deflection angle = arctan (third distance / first distance), where / is a division sign.

[0216] ​The second horizontal deflection angle is shown in formula (1):

[0217]

[0218] Where Δα_horizontal represents the second horizontal deflection angle, distance_x represents the second distance, and distance_y represents the first distance.

[0219] The second vertical deflection angle is shown in formula (2):

[0220]

[0221] Where Δα_vertical represents the second vertical deflection angle, distance_z represents the third distance, and distance_y represents the first distance.

FIG. 23B for FIG. 23A The corresponding top view, FIG. 23C for FIG. 23A The corresponding left view, combined with FIG. 23B and FIG. 23C It can be seen that the first and second reference lines coincide, so the determined first distance is d1, and the second and third distances are both 0. According to the arctangent function, the second horizontal deflection angle = arctan(0 / d1) = 0, and the second vertical deflection angle = arctan(0 / d1) = 0.

[0224] by FIG. 24A In the scenario shown, the remote control is positioned directly in front of the center of the smart TV screen, and the direction the remote control is pointing is not perpendicular to the smart TV screen.

According to the arctangent function, the second horizontal deflection angle = arctan(0 / d1) = 0, and the second vertical deflection angle = arctan(0 / d1) = 0.

[0225] by FIG. 25AIn the illustrated scenario, the remote control device is not located directly in front of the center of the smart TV screen, and the pointing direction of the remote control device is not perpendicular to the smart TV screen. For example, FIG. 25B For FIG. 25A The corresponding top view, FIG. 25C For FIG. 25A The corresponding left view, in combination with FIG. 25B With FIG. 25C It can be seen that the first reference line and the second reference line do not coincide, so the first distance determined is d1, the second distance is d2, and the third distance is d3. According to the arctangent function, the second horizontal deflection angle = arctan (d2 / d1), and the second vertical deflection angle = arctan (d3 / d1).

[0226] S2003, the remote control device determines a third deflection angle based on the second reference line and the pointing direction of the remote control device.

[0227] In the embodiments of the present application, the third deflection angle includes a third horizontal deflection angle and / or a third vertical deflection angle.

[0228] In one possible implementation, the angle between the pointing direction of the remote control device and a fifth reference surface is taken as the third horizontal deflection angle, where the fifth reference surface is a plane perpendicular to the horizontal plane and including the first reference line. The angle between the pointing direction of the remote control device and a sixth reference surface is taken as the third vertical deflection angle, where the sixth reference surface is a plane parallel to the horizontal plane and including the first reference line. Finally, the obtained third horizontal deflection angle and third vertical deflection angle are taken as the third deflection angle.

[0229] It should be understood that the method of calculating the angle between the pointing direction of the remote control device and the fifth reference surface, or the angle between the pointing direction of the remote control device and the sixth reference surface can refer to the calculation method of the angle between a straight line and a plane in geometry, which is not described here.

[0230] S2004, the remote control device determines a first deflection angle based on the second deflection angle and the third deflection angle.

[0231] In the embodiments of the present application, if the pointing direction of the remote control device is not located between the first reference line and the second reference line, the sum of the second horizontal deflection angle and the third horizontal deflection angle is the first horizontal deflection angle, and the sum of the second vertical deflection angle and the third vertical deflection angle is the first vertical deflection angle.

[0232] If the pointing direction of the remote control device is located between the first reference line and the second reference line, the difference between the second horizontal deflection angle and the third horizontal deflection angle is the first horizontal deflection angle, and the difference between the second vertical deflection angle and the third vertical deflection angle is the first vertical deflection angle.

[0233] Finally, the first horizontal deflection angle and the first vertical deflection angle obtained are taken as the first deflection angle.

[0234] The following examples all use smart TV screens as the example.

[0235] by FIG. 26A In the scenario shown, the remote control is positioned directly in front of the center of the smart TV screen, and the direction the remote control is pointing is perpendicular to the smart TV screen. FIG. 26B for FIG. 26A The corresponding top view, FIG. 26C for FIG. 26A The corresponding left view, combined with FIG. 26B and FIG. 26C It can be seen that the first and second reference lines coincide, therefore the determined first distance is d1, and the second and third distances are both 0. According to the arctangent function, the second horizontal deflection angle = arctan(0 / d1) = 0, and the second vertical deflection angle = arctan(0 / d1) = 0. Based on the pointing direction of the remote control device and the fifth reference plane, the third horizontal deflection angle can be determined, and it is 0. Based on the pointing direction of the remote control device and the sixth reference plane, the third vertical deflection angle can be determined, and it is also 0. Therefore, the first horizontal deflection angle is 0, and the first vertical deflection angle is 0.

[0236] by FIG. 27A In the scenario shown, the remote control is positioned directly in front of the center of the smart TV screen, and the direction the remote control is pointing is not perpendicular to the smart TV screen. FIG. 27B for FIG. 27A The corresponding top view, FIG. 27C for FIG. 27A The corresponding left view, combined with FIG. 27B and FIG. 27C It can be seen that the first and second reference lines coincide, therefore the determined first distance is d1, and the second and third distances are both 0. According to the arctangent function, the second horizontal deflection angle = arctan(0 / d1) = 0, and the second vertical deflection angle = arctan(0 / d1) = 0. Based on the pointing direction of the remote control device and the fifth reference plane, the third horizontal deflection angle can be determined as angle a2. Based on the pointing direction of the remote control device and the sixth reference plane, the third vertical deflection angle can be determined as angle b2. Therefore, the first horizontal deflection angle is a2, and the first vertical deflection angle is b2.

[0237] by FIG. 28A In the scenario shown, the remote control is positioned in front of the smart TV screen, not in the center, and its orientation is not perpendicular to the screen. FIG. 28BFor FIG. 28A the corresponding top view, FIG. 28C For FIG. 28A the corresponding left view, in combination FIG. 28B With FIG. 28C It can be seen that the first reference line and the second reference line do not coincide, so the determined first distance is d1, the second distance is d2, and the third distance is d3. According to the arctangent function, the second horizontal deflection angle = arctan (d2 / d1), and the second vertical deflection angle = arctan (d3 / d1). Based on the pointing direction of the remote control device and the fifth reference surface, the third horizontal deflection angle can be determined, which is angle a2, and based on the pointing direction of the remote control device and the sixth reference surface, the third vertical deflection angle can be determined, which is angle b2. Since the pointing direction of the remote control device is located between the first reference line and the second reference line, the first horizontal deflection angle is (arctan (d2 / d1)-a2), and the first vertical deflection angle is (arctan (d3 / d1)-b2).

[0238] In the scene shown in FIG. 29A , the position of the remote control device is located in front of the non-central position of the smart TV screen, and the placement direction of the remote control device is not perpendicular to the smart TV screen. For example, the first horizontal deflection angle and the first vertical deflection angle are determined according to the above embodiment, FIG. 29B For FIG. 29A the corresponding top view, FIG. 29C For FIG. 29A the corresponding left view, in combination FIG. 29B With FIG. 29C It can be seen that the first reference line and the second reference line do not coincide, so the determined first distance is d1, the second distance is d2, and the third distance is d3. According to the arctangent function, the second horizontal deflection angle = arctan (d2 / d1), and the second vertical deflection angle = arctan (d3 / d1). Based on the pointing direction of the remote control device and the fifth reference surface, the third horizontal deflection angle can be determined, which is angle a2, and based on the pointing direction of the remote control device and the sixth reference surface, the third vertical deflection angle can be determined, which is angle b2. Since the pointing direction of the remote control device is located between the first reference line and the second reference line, the first horizontal deflection angle is (arctan (d2 / d1)-a2), and the first vertical deflection angle is (arctan (d3 / d1)-b2).

[0239] In the embodiments of the present application, the first horizontal deflection angle and the first vertical deflection angle determined by the above embodiments are all in angle system. In order to facilitate subsequent calculation, the first horizontal deflection angle and the first vertical deflection angle can be modified to radian system according to the corresponding relationship between angle and radian. Wherein, the corresponding relationship between angle and radian is: 1 degree = π / 180 radian, / is a semicolon.

The remote control device determines a second virtual arc surface based on the first reference position. The center position of the second virtual arc surface coincides with the first reference position, and the tangent at the center position of the second virtual arc surface is perpendicular to the second reference line.

[0255] The remote control device determines a second reference position on a first reference line, at a first preset distance from its current position. Since the first and second reference lines coincide, the determined second reference position also coincides with the first reference position. The second virtual arc surface is adjusted based on both the first and second reference positions, resulting in a first and second virtual arc surface that coincide.

[0259] In the embodiments of the present application, the first offset distance includes a first horizontal offset distance and a first vertical offset distance.

[0260] Based on the first horizontal deflection angle and the first vertical deflection angle, the first horizontal offset distance and the first vertical offset distance are determined, which can include the following three possible implementation manners:

[0261] In the first possible implementation manner, the product of the radius length of the first virtual arc surface and the first horizontal deflection angle is taken as a second horizontal offset distance, and the product of the first horizontal adjustment ratio and the second horizontal offset distance is taken as the first horizontal offset distance; the product of the radius length of the first virtual arc surface and the first vertical deflection angle is taken as a second vertical offset distance, and the product of the first vertical adjustment ratio and the second vertical offset distance is taken as the first vertical offset distance. It should be understood that the first horizontal adjustment ratio and the first vertical adjustment ratio are preset values, and the first horizontal adjustment ratio and the first vertical adjustment ratio can be the same or different. The first horizontal adjustment ratio and the first vertical adjustment ratio can be set to a decimal number between 0 and 1, or a number greater than 1.

[0262] The first horizontal offset distance is shown in formula (3):

[0263] Δd_horizontal=k1_horizontal*R*Δα_horizontal(3)

[0264] Wherein, Δd_horizontal represents the first horizontal offset distance, k1_horizontal represents the first horizontal adjustment ratio, R represents the radius length of the first virtual arc surface, and Δα_horizontal represents the first horizontal deflection angle.

[0265] The first vertical offset distance is shown in formula (4):

[0266] Δd_vertical = k1_vertical * R * Δα_vertical (4)

[0267] wherein Δd_vertical represents the first vertical offset distance, k1_vertical represents the first vertical adjustment ratio, R represents the radius length of the first virtual arc surface, and Δα_vertical represents the first vertical deflection angle.

[0268] In the above possible implementation, the product of the radius length of the first virtual arc surface and the first horizontal deflection angle is the horizontal arc length corresponding to the first horizontal deflection angle. The product of the horizontal arc length corresponding to the first horizontal deflection angle and the first horizontal adjustment ratio can be taken as the first horizontal offset distance. The product of the radius length of the first virtual arc surface and the first vertical deflection angle is the vertical arc length corresponding to the first vertical deflection angle. The product of the vertical arc length corresponding to the first vertical deflection angle and the first vertical adjustment ratio can be taken as the first vertical offset distance.

[0269] In the second possible implementation, the product of the radius length of the first virtual arc surface and the first horizontal deflection angle is taken as the first horizontal offset distance, and the product of the radius length of the first virtual arc surface and the first vertical deflection angle is taken as the first vertical offset distance.

[0270] The first horizontal offset distance is shown in formula (5):

[0271] Δd_horizontal = R * Δα_horizontal (5)

[0272] wherein Δd_horizontal represents the first horizontal offset distance, R represents the radius length of the first virtual arc surface, and Δα_horizontal represents the first horizontal deflection angle.

[0273] The first vertical offset distance is shown in formula (6):

[0274] Δd_vertical = R * Δα_vertical (6)

[0275] wherein Δd_vertical represents the first vertical offset distance, R represents the radius length of the first virtual arc surface, and Δα_vertical represents the first vertical deflection angle.

[0276] In the above possible implementation, the product of the radius length of the first virtual arc surface and the first horizontal deflection angle is the horizontal arc length corresponding to the first horizontal deflection angle. The horizontal arc length corresponding to the first horizontal deflection angle can be directly used as the first horizontal offset distance. The product of the radius length of the first virtual arc surface and the first vertical deflection angle is the vertical arc length corresponding to the first vertical deflection angle. The vertical arc length corresponding to the first vertical deflection angle can be directly used as the first vertical offset distance.

[0277] In a third possible implementation, the product of the first preset value and the first horizontal deflection angle is used as the first horizontal offset distance, and the product of the second preset value and the first vertical deflection angle is used as the first vertical offset distance. The first preset value and the second preset value can be the same or different.

[0278] The first horizontal offset distance is shown in formula (7):

[0279] Δd_horizontal=K1*Δα_horizontal(7)

[0280] wherein Δd_horizontal represents the first horizontal offset distance, K1 represents the first preset value, and Δα_horizontal represents the first horizontal deflection angle.

[0281] The first vertical offset distance is shown in formula (8):

[0282] Δd_vertical=K2*Δα_vertical(8)

[0283] wherein Δd_vertical represents the first vertical offset distance, K2 represents the second preset value, and Δα_vertical represents the first vertical deflection angle.

[0284] It should be understood that the first preset value and the second preset value can be the same or different. The first preset value and the second preset value can be set to a decimal number between 0 and 1, or a number greater than 1.

[0285] In the embodiments of the present application, after the first horizontal offset distance and the first vertical offset distance are determined, the following method can be used to determine the cursor position: first, based on the center position of the screen device and the first horizontal offset distance, a first coordinate value of the cursor position in the x-axis direction is determined, and then, based on the center position of the screen device and the first vertical offset distance, a second coordinate value of the cursor position in the z-axis direction is determined. The first coordinate value and the second coordinate value constitute the coordinates of the cursor position. According to the coordinates of the cursor position, the cursor position of the remote control device in the screen device can be determined, and the cursor is displayed at the coordinates of the cursor position.

[0286] Generally, the sum of the center position of the screen device and the first horizontal offset distance is used as the first coordinate value of the cursor position in the x-axis direction; the sum of the center position of the screen device and the first vertical offset distance is used as the second coordinate value of the cursor position in the z-axis direction.

[0287] The following examples all use smart TV screens as the example.

[0288] For example, such as FIG. 34A As shown in the top view and the left view of 34B, the remote control device is located directly in front of the center of the smart TV screen. The direction of the remote control device is perpendicular to the smart TV screen, and the cursor corresponding to the remote control device is displayed at point A on the smart TV screen, where point A is the center of the smart TV screen.

[0289] The user deflects the remote control device, where the first horizontal deflection angle of the remote control device is a1, the first vertical deflection angle of the remote control device is b1, and the radius of the virtual arc surface is R.

[0290] like FIG. 34C In the top view, the product of the radius R of the virtual arc surface and the first horizontal deflection angle a1 is the horizontal arc length between points B and C. The product of the horizontal arc length between points B and C and the first horizontal adjustment ratio is used as the first horizontal offset distance. Based on the center position of the smart TV screen (i.e., the coordinate value of point A in the x-axis direction) and the first horizontal offset distance, the first coordinate value of the cursor position in the x-axis direction (i.e., the coordinate value of point D in the x-axis direction) can be determined.

[0291] like FIG. 34D In the left view, the product of the radius R of the virtual arc surface and the first vertical deflection angle b1 is the vertical arc length between points B and C. The product of the vertical arc length between points B and C and the first vertical adjustment ratio is used as the first vertical offset distance. Based on the center position of the smart TV screen (the coordinate value of point A in the z-axis direction) and the first vertical offset distance, the second coordinate value of the cursor position in the z-axis direction (i.e., the coordinate value of point D in the z-axis direction) can be determined.

[0292] Finally, the first coordinate value and the second coordinate value form the coordinates of the cursor position. Based on the coordinates of the cursor position, the cursor position (i.e., point D) of the cursor corresponding to the remote control device on the smart TV screen is determined, and the cursor is displayed at the coordinates of that cursor position.

[0293] In the above embodiments, when the distance between the remote control device and the screen device is different or the pointing direction of the remote control device is different, the distance the cursor moves on the screen device is still the same when the remote control device is deflected by the same angle. The user can accurately control the movement accuracy of the cursor and improve the user experience.

[0294] In the case that the pointing direction of the remote control device deflects for multiple times, the cursor position can be determined by two possible implementations, which are explained below by taking the case that the pointing direction of the remote control device deflects for the Nth time as an example, where N is greater than 1. In the case that the pointing direction of the remote control device deflects for the Nth time, the determination of the cursor position corresponding to the remote control device in the screen device can include the following two possible implementations.

[0295] The first possible implementation can determine the cursor position by using the steps shown in FIG. 8, which will not be described herein. FIG. 5

[0296] The second possible implementation, in the case that the pointing direction of the remote control device deflects for the (N-1)th time, the remote control device determines the cursor position corresponding to the remote control device in the (N-1)th deflection. The remote control device determines the relative offset distance of the pointing direction of the remote control device in the Nth deflection, relative to the pointing direction of the remote control device in the (N-1)th deflection. The remote control device determines the cursor position corresponding to the remote control device in the Nth deflection, based on the cursor position corresponding to the remote control device in the (N-1)th deflection and the relative offset distance of the pointing direction of the remote control device in the Nth deflection.

[0297] In one possible implementation, the relative offset distance includes a relative horizontal offset distance and a relative vertical offset distance. The remote control device first determines the seventh coordinate value of the cursor position in the x-axis direction, based on the cursor position corresponding to the remote control device in the (N-1)th deflection and the relative horizontal offset distance. Then, the remote control device determines the eighth coordinate value of the cursor position in the z-axis direction, based on the cursor position corresponding to the remote control device in the (N-1)th deflection and the relative vertical offset distance. The seventh coordinate value and the eighth coordinate value constitute the coordinates of the cursor position corresponding to the Nth deflection. According to the coordinates of the cursor position corresponding to the Nth deflection, the cursor position corresponding to the Nth deflection of the cursor corresponding to the remote control device in the screen device can be determined, and the cursor is displayed at the cursor position.

[0298] In order to improve the accuracy of the determined cursor position, the embodiments of the present application further provide a cursor position determination method. The remote control device detects a third operation on the touchpad of the remote control device. The remote control device adjusts the radius length of the first virtual arc surface from a first length to a second length in response to the third operation, where the second length is smaller than the first length.

[0299] ​The radius length of the first virtual arc surface is the second length when the user performs a third operation on the touchpad of the remote control device, and the radius length of the first virtual arc surface returns to the first length when the user does not perform the third operation on the touchpad of the remote control device. In the embodiments of the present application, the third operation can be understood as the touchpad of the remote control device being pressed, etc., which is not limited herein. In the case where the third operation is the touchpad of the remote control device being pressed, the radius length of the first virtual arc surface is the second length when the user presses the touchpad of the remote control device. The radius length of the first virtual arc surface returns to the first length when the user does not press the touchpad of the remote control device.

[0300] In a possible implementation, the remote control device receives a second operation, wherein the second operation comprises the first operation and a third operation on the touchpad of the remote control device, wherein the first operation comprises an operation of deflecting the pointing direction of the remote control device, and the remote control device determines a first deflection angle of the pointing direction of the remote control device relative to the first reference line in the case where the pointing direction of the remote control device is deflected, wherein the first reference line is a line between the position of the remote control device and the center position of the screen device, the remote control device determines a first offset distance according to the first deflection angle and the first virtual arc surface, wherein the remote control device is located inside the arc of the first virtual arc surface, the screen device is located outside the arc of the first virtual arc surface, the center position of the first virtual arc surface is located on the first reference line, a tangent line at the center position of the first virtual arc surface is perpendicular to the first reference line, the radius length of the first virtual arc surface is the second length, and the remote control device determines a cursor position of the cursor corresponding to the remote control device in the screen device based on the center position of the screen device and the first offset distance.

[0301] For ease of understanding, the third operation is described as the touchpad of the remote control device being pressed in the following.

[0302] The radius length of the first virtual arc surface is the second length during the process in which the user presses the touchpad of the remote control device, and the user can deflect the remote control device so that the pointing direction of the remote control device is deflected. The deflection of the pointing direction of the remote control device comprises horizontal deflection and / or vertical deflection. The first deflection angle of the pointing direction of the remote control device relative to the first reference line comprises a first horizontal deflection angle and / or a first vertical deflection angle.

[0303] In the case where the radius length of the first virtual arc surface is the first length, the user deflecting the remote control device can determine a first horizontal offset distance corresponding to the first horizontal deflection angle and a first vertical offset distance corresponding to the first vertical deflection angle. The first horizontal offset distance is determined based on the product of the radius length (the first length) of the first virtual arc surface and the first horizontal deflection angle, and the first vertical offset distance is determined based on the product of the radius length (the first length) of the first virtual arc surface and the first vertical deflection angle.

[0304] When the radius of the first virtual arc surface is equal to the second length, and the user deflects the remote control device by the same angle, the fifth horizontal offset distance corresponding to the first horizontal deflection angle and the fifth vertical offset distance corresponding to the first vertical deflection angle can be determined. The fifth horizontal offset distance is determined based on the product of the radius of the first virtual arc surface (the second length) and the first horizontal deflection angle, and the fifth vertical offset distance is determined based on the product of the radius of the first virtual arc surface (the second length) and the first vertical deflection angle.

[0305] Based on the above process, it can be seen that since the second length is less than the first length, the fifth horizontal offset distance is less than or equal to the first horizontal offset distance, and the fifth vertical offset distance is less than or equal to the first vertical offset distance.

[0306] The following examples all use smart TV screens as the example.

[0307] For example, such as FIG. 34A As shown in the top view and the left view of 34B, the remote control device is located directly in front of the center of the smart TV screen. The pointing direction of the remote control device is perpendicular to the smart TV screen. The cursor corresponding to the remote control device is displayed at point A on the smart TV screen, where point A is the center of the smart TV screen.

[0308] Without the user pressing the touchpad on the remote control device, and with the radius of the virtual arc surface being R1, the user deflects the remote control device, where the first horizontal deflection angle of the remote control device is a1, and the first vertical deflection angle of the remote control device is b1. For example... FIG. 35A In the top view, the product of the radius R1 of the first virtual arc surface and the first horizontal deflection angle a1 is the horizontal arc length between points B and C. The product of the horizontal arc length between points B and C and the first horizontal adjustment ratio is used as the first horizontal offset distance. Based on the center position of the smart TV screen (i.e., the coordinates of point A in the x-axis direction) and the first horizontal offset distance, the first coordinate value of the cursor position in the x-axis direction (i.e., the coordinates of point D in the x-axis direction) can be determined. For example... FIG. 35B In the left view, the product of the radius R1 of the first virtual arc surface and the first vertical deflection angle b1 is the vertical arc length between points B and C. The product of the vertical arc length between points B and C and the first vertical adjustment ratio is used as the first vertical offset distance. Based on the center position of the smart TV screen (i.e., the coordinate value of point A in the z-axis direction) and the first vertical offset distance, the second coordinate value of the cursor position in the z-axis direction (i.e., the coordinate value of point D in the z-axis direction) can be determined. Finally, the first coordinate value and the second coordinate value form the coordinates of the cursor position. Based on the coordinates of the cursor position, the cursor position (i.e., point D) of the cursor corresponding to the remote control device on the smart TV screen is determined, and the cursor is displayed at the coordinates of that cursor position.

[0309] In the case that the user presses the touchpad on the remote control device, the radius of the virtual arc surface is R2, where R2 is less than R1, the user deflects the remote control device, where the first horizontal deflection angle of the remote control device is a1, and the first vertical deflection angle of the remote control device is b1. As shown in the top view of FIG. 1C, the product of the radius R2 of the first virtual arc surface and the first horizontal deflection angle a1 is the horizontal arc length between the two points EF. The first horizontal offset distance is the product of the horizontal arc length between the two points EF and the first horizontal adjustment ratio. The first coordinate value of the cursor position in the x-axis direction (i.e., the coordinate value of the point G in the x-axis direction) can be determined based on the center position of the smart TV screen (i.e., the coordinate value of the point A in the x-axis direction) and the first horizontal offset distance. FIG. 35A FIG. 35B As shown in the left view of FIG. 1C, the product of the radius R2 of the first virtual arc surface and the first vertical deflection angle b1 is the vertical arc length between the two points EF. The first vertical offset distance is the product of the vertical arc length between the two points EF and the first vertical adjustment ratio. The second coordinate value of the cursor position in the z-axis direction (i.e., the coordinate value of the point G in the z-axis direction) can be determined based on the center position of the smart TV screen (i.e., the coordinate value of the point A in the z-axis direction) and the first vertical offset distance. Finally, the first coordinate value and the second coordinate value constitute the coordinates of the cursor position. According to the coordinates of the cursor position, the cursor position (i.e., the point G) of the cursor corresponding to the remote control device in the smart TV screen is determined, and the cursor is displayed at the cursor position.

[0310] In the above embodiments, in the case that the radius of the first virtual arc surface is reduced, the same deflection angle of the remote control device can reduce the moving speed of the cursor and improve the accuracy of the determined cursor position.

[0311] In order to improve the accuracy of the determined cursor position, the embodiments of the present application also provide a cursor position determination method, which can include the following steps as shown in FIG. 3A: FIG. 36

[0312] S3601, in the case that the remote control device receives a fourth operation, the remote control device determines a first deflection angle of a pointing direction of the remote control device relative to a first reference line, where the fourth operation includes an operation of deflecting the pointing direction of the remote control device and a fifth operation of the touchpad of the remote control device, and the first reference line is a line connecting the position of the remote control device and the center position of the screen device.

[0313] In the embodiments of the present application, the fifth operation can be understood as the touchpad of the remote control device being pressed, etc., which is not limited herein. For ease of understanding, the fifth operation is described below as the touchpad of the remote control device being pressed.

[0314] ​​The method for determining the first deflection angle in the above step is similar to the method for determining the first deflection angle in S501, and will not be repeated here.

[0315] In the case where the touchpad of the remote control device is pressed, the radius length of the virtual arc surface is unchanged, i.e., the radius length of the first virtual arc surface is the first length. In the case where the touchpad of the remote control device is pressed, if the pointing direction of the remote control device is deflected, the deflection of the pointing direction of the remote control device includes a horizontal deflection and / or a vertical deflection. The first deflection angle of the pointing direction of the remote control device relative to the first reference line includes a first horizontal deflection angle and / or a first vertical deflection angle.

[0316] S3602, the remote control device determines a third horizontal offset distance based on the first horizontal deflection angle and the second horizontal adjustment ratio, and determines a third vertical offset distance based on the first vertical deflection angle and the second vertical adjustment ratio.

[0317] In the embodiments of the present application, the product of the first horizontal deflection angle and the second horizontal adjustment ratio is taken as the third horizontal offset distance, and the product of the first vertical deflection angle and the second vertical adjustment ratio is taken as the third vertical offset distance.

[0318] For ease of understanding, it can be understood that the product of the first horizontal deflection angle, the second horizontal adjustment ratio and the radius length 1 is taken as the third horizontal offset distance. Similarly, it can be understood that the product of the first vertical deflection angle, the second vertical adjustment ratio and the radius length 1 is taken as the third vertical offset distance.

[0319] In the embodiments of the present application, the first horizontal deflection angle and the first vertical deflection angle determined by the above implementation are both in angle units, in order to facilitate subsequent calculation, the first horizontal deflection angle and the first vertical deflection angle can be modified to radian units by using the corresponding relationship between angle and radian. The corresponding relationship between angle and radian is: 1 degree = π / 180 radians, / is a division sign.

[0320] It should be understood that the second horizontal adjustment ratio and the second vertical adjustment ratio are preset values, and the second horizontal adjustment ratio and the second vertical adjustment ratio can be the same or different. The second horizontal adjustment ratio and the second vertical adjustment ratio can be set to a decimal between 0 and 1, or a number greater than 1.

[0321] Based on the above process, it can be seen that the third horizontal offset distance and the third vertical offset distance are both independent of the radius length of the first virtual arc surface.

[0322] S3603, the remote control device determines the cursor position of the cursor corresponding to the remote control device in the screen device based on the center position of the screen device, the third horizontal offset distance and the third vertical offset distance.

[0323] In this embodiment, after determining the third horizontal offset distance and the third vertical offset distance, the cursor position can be determined using the following method: First, based on the center position of the screen device and the third horizontal offset distance, the third coordinate value of the cursor position in the x-axis direction is determined; then, based on the center position of the screen device and the third vertical offset distance, the fourth coordinate value of the cursor position in the z-axis direction is determined. The third coordinate value and the fourth coordinate value constitute the coordinates of the cursor position. Based on the coordinates of the cursor position, the cursor position of the cursor corresponding to the remote control device on the screen device can be determined, and the cursor can be displayed at the coordinates of that cursor position.

[0324] The following examples all use smart TV screens as the example.

[0325] For example, such as FIG. 34A As shown in the top view and the left view of 34B, the remote control device is located directly in front of the center of the smart TV screen. The pointing direction of the remote control device is perpendicular to the smart TV screen. The cursor corresponding to the remote control device is displayed at point A on the smart TV screen, where point A is the center of the smart TV screen.

[0326] When the user presses the touchpad on the remote control device, the user deflects the remote control device, where the first horizontal deflection angle of the remote control device is a1, and the first vertical deflection angle of the remote control device is b1. For example... FIG. 37 The top view of point A, the product of the first horizontal deflection angle a1 and the second horizontal adjustment ratio, is used as the third horizontal offset distance. Based on the center position of the smart TV screen (i.e., the coordinates of point A in the x-axis direction) and the third horizontal offset distance, the third coordinate value of the cursor position in the x-axis direction (i.e., the coordinates of point H in the x-axis direction) can be determined. For example... FIG. 37 In the left view of B, the product of the first vertical deflection angle b1 and the second vertical adjustment ratio is used as the third vertical offset distance. Based on the center position of the smart TV screen (i.e., the coordinates of point A in the z-axis direction) and the third vertical offset distance, the fourth coordinate value of the cursor position in the z-axis direction (i.e., the coordinates of point H in the z-axis direction) is determined. Finally, the third and fourth coordinate values ​​form the coordinates of the cursor position. Based on the coordinates of the cursor position, the cursor position (i.e., point H) of the remote control device on the smart TV screen is determined, and the cursor is displayed at the coordinates of that cursor position.

[0327] In the above embodiments, the cursor position changes with the first horizontal deflection angle and the first vertical deflection angle, and is not affected by the radius length of the first virtual arc surface, providing a convenient method for determining the cursor position.

[0328] To improve the accuracy of cursor position, embodiments of this application also provide a cursor position determination method, which may include, for example:FIG. 38 The following steps are shown:

[0329] S3801, in the case that the remote control device receives a sixth operation on the touchpad, the remote control device determines a horizontal movement distance and a vertical movement distance of the remote control device, wherein the sixth operation includes an operation of moving the remote control device and a seventh operation on the touchpad of the remote control device.

[0330] In the embodiments of the present application, the seventh operation can be understood as the touchpad of the remote control device being pressed, etc., which is not limited herein. For ease of understanding, the following are described with the seventh operation as the touchpad of the remote control device being pressed.

[0331] In the case that the touchpad of the remote control device is pressed, the radius length of the virtual arc surface is unchanged, i.e., the radius length of the first virtual arc surface is the first length.

[0332] S3802, the remote control device determines a fourth horizontal offset distance based on the horizontal movement distance and a third horizontal adjustment ratio, and determines a fourth vertical offset distance based on the vertical movement distance and a third vertical adjustment ratio.

[0333] In the embodiments of the present application, the product of the horizontal movement distance and the third horizontal adjustment ratio is taken as the fourth horizontal offset distance, and the product of the vertical movement distance and the third vertical adjustment ratio is taken as the fourth vertical offset distance.

[0334] It should be understood that the third horizontal adjustment ratio and the third vertical adjustment ratio are preset values, and the third horizontal adjustment ratio and the third vertical adjustment ratio can be the same or different. The third horizontal adjustment ratio and the third vertical adjustment ratio can be set as a decimal between 0 and 1, or a number greater than 1.

[0335] Based on the above process, it can be seen that the fourth horizontal offset distance and the fourth vertical offset distance are both irrelevant to the radius length of the first virtual arc surface.

[0336] S3803, the remote control device determines a cursor position of the cursor corresponding to the remote control device in the screen device based on the center position of the screen device, the fourth horizontal offset distance, and the fourth vertical offset distance.

[0337] In the embodiments of the present application, after the fourth horizontal offset distance and the fourth vertical offset distance are determined, the following method can be used to determine the cursor position: first, based on the center position of the screen device and the fourth horizontal offset distance, a fifth coordinate value of the cursor position in the x-axis direction is determined, and then, based on the center position of the screen device and the fourth vertical offset distance, a sixth coordinate value of the cursor position in the z-axis direction is determined. The fifth coordinate value and the sixth coordinate value constitute the coordinates of the cursor position. According to the coordinates of the cursor position, the cursor position of the cursor corresponding to the remote control device in the screen device can be determined, and the cursor is displayed at the cursor position.

[0338] The following examples are all based on the screen device being a smart TV screen.

[0339] For example, as shown in the top view of A and the left view of 34B, the position of the remote control device is located directly in front of the center position of the screen, the pointing direction of the remote control device is perpendicular to the smart TV screen, and the cursor corresponding to the remote control device is displayed at point A in the smart TV screen, wherein point A is the center position of the smart TV screen. FIG. 34A In the case that the user presses the touchpad on the remote control device, the user moves the remote control device, wherein the horizontal moving distance of the remote control device is x1, and the vertical moving distance of the remote control device is z1. As shown in the top view of A, the product of the horizontal moving distance x1 and the second horizontal adjustment ratio is taken as the fourth horizontal offset distance, i.e., based on the center position of the smart TV screen (i.e., the coordinate value of point A in the x-axis direction) and the fourth horizontal offset distance, the fifth coordinate value of the cursor position in the x-axis direction (i.e., the coordinate value of point K in the x-axis direction) can be determined. As shown in the left view of B, the product of the vertical moving distance z1 and the second vertical adjustment ratio is taken as the fourth vertical offset distance, i.e., based on the center position of the smart TV screen (i.e., the coordinate value of point A in the z-axis direction) and the fourth vertical offset distance, the sixth coordinate value of the cursor position in the z-axis direction (i.e., the coordinate value of point K in the z-axis direction) can be determined. Finally, the fifth coordinate value and the sixth coordinate value constitute the coordinates of the cursor position, according to which the cursor position of the cursor corresponding to the remote control device in the smart TV screen (i.e., point K) can be determined, and the cursor is displayed at the cursor position.

[0340] FIG. 39 In the above embodiments, the cursor position changes with the change of the horizontal moving distance and the vertical moving distance, and is not affected by the radius length of the first virtual arc surface, thereby providing a convenient method for determining the cursor position. FIG. 39 In the above embodiments, the cursor position changes with the change of the horizontal moving distance and the vertical moving distance, and is not affected by the radius length of the first virtual arc surface, thereby providing a convenient method for determining the cursor position.
