Description

Free-school cursor tracking method and system

The invention relates to a cursor tracking alignment system, and in particular to an off-track cursor tracking registration method and a system thereof for performing cursor tracking alignment without correction.

In recent years, due to the integration of Micro Electro Mechanical Systems (MEMS) technology and semiconductor processes, dynamic sensing components have become smaller and more sophisticated. Currently, dynamic sensor elements such as Gyroscopes and Accelerometers are widely used in a variety of aerial mouse devices. For example, the aerial mouse device can be realized by a smart remote control device of a home appliance, an operation rocker device of a game machine, a pointing control device for a briefing, and a handheld device such as a smart phone.

However, when the user operates a conventional aerial mouse device in a conventional vernier tracking aligning system, there may be a problem of vernier error. Referring to FIG. 1A to FIG. 1D, FIG. 1A to FIG. 1D are movement trajectories of the position pointed by the conventional aerial mouse device 10 and movement of the cursor 14 on the actual screen 12 when the user operates the conventional aerial mouse device 10. A schematic representation of the trajectory. In FIG. 1A, when the conventional aerial mouse device 10 is pointed to the center of the actual screen 12, the cursor 14 will be located in the center of the actual screen 12. In FIG. 1B, when the user turns the conventional aerial mouse device 10 to the right and points to the right border of the actual screen 12, the cursor 14 moves from the center of the actual screen 12 to the right to the right border of the actual screen 12.

In FIG. 1C, when the user continues to rotate the conventional aerial mouse device 10 to the right and points out of the right border of the actual screen 12, the cursor 14 will stay at the right border of the actual screen. Next, in FIG. 1D, when the user turns the traditional aerial mouse device 10 to the left and points to the right border of the actual screen 12, the cursor 14 moves to the left from the right border of the actual screen 12, causing the traditional air slide. There is a cursor error MErr between the coordinate point of the mouse device 10 pointing to the actual screen 12 and the coordinate point of the cursor 14 on the actual screen 12.

Therefore, as the operation time of the conventional airborne mouse device 10 of the conventional cursor tracking alignment system increases, the accumulated cursor error may also become larger. Although, there are currently products on the market that have an airborne mouse device that corrects the cursor error function. When a cursor error occurs, the user can press the correction button of the aerial mouse device to stop the movement of the cursor, and move the aerial mouse device to the actual screen for correction, and then release the correction button. However, such an aerial mouse device requires the user to interrupt the operation, and manual correction by itself may make the user feel inconvenient.

In addition, there are still operators who track the aerial mouse device by setting up an image capturing device on both sides of the actual screen, and thereby automatically correcting according to the air mouse device and the coordinates of the current cursor. However, such a cursor tracking alignment method or system requires additional image capture devices and image processing software to be installed, which will increase the manufacturing cost and pass it on to the user.

Embodiments of the present invention provide a method for tracking calibration of a cursor-free cursor. The school-free cursor tracking alignment method is applicable to a school-free cursor tracking aligning system having an air mouse device and a computing device, wherein the computer device has an actual screen to display the cursor. First, the data format of the aerial mouse device, the virtual screen and the absolute coordinate range of the application screen are announced to the computer device through the standard specification, wherein the application screen corresponds to the actual screen, and there is a coordinate conversion relationship. The coordinate point of the current virtual cursor is obtained according to the motion sensing signal generated by the aerial mouse device. Determining whether the first axial coordinate value of the coordinate point of the current virtual cursor exceeds the first axial boundary of the application screen and whether the second axial coordinate value of the coordinate point of the current virtual cursor exceeds the second axial boundary of the application screen. If the first axial coordinate value exceeds the first axial boundary and the second axial coordinate value exceeds the second axial boundary, no cursor movement signal is generated. A cursor movement signal is generated if the first axial coordinate value does not exceed the first axial boundary or the second axial coordinate value does not exceed the second axial boundary. The data format of the converted cursor movement signal is a data format acceptable to the computer device. The operating system of the computer device performs coordinate conversion on the format converted cursor movement signal according to the coordinate conversion relationship. The operating system obtains the coordinate point of the cursor on the actual screen according to the cursor movement signal after the coordinate conversion, and displays the cursor on the actual screen accordingly.

In addition, the embodiment of the present invention further provides a plurality of school-free cursor tracking aligning systems for performing the above-mentioned ex-study cursor tracking aligning method.

The invention provides a method for tracking and positioning of a cursor-free cursor. When the user operates the airborne mouse device of the calibration-free cursor tracking alignment system that executes the exemption cursor tracking method, the user does not need to manually correct the cursor. The error can therefore improve the user's convenience in using the aerial mouse device. In addition, compared with the conventional cursor tracking and aligning system, the image capturing device and the image software are used to automatically correct the cursor error, and the school-free vernier tracking aligning system of the embodiment of the invention has the advantages of low cost.

The detailed description of the present invention and the accompanying drawings are to be understood by the claims The scope is subject to any restrictions.

An exemplary embodiment of the present invention provides an unobstructed cursor tracking alignment method and system for cursor tracking alignment without correction, and the user does not need to interrupt the current operation, and does not need to additionally install image processing software and Set up the image capture device on both sides of the actual screen. Accordingly, the off-campus cursor tracking alignment method and its system have the advantages of low cost and high convenience compared to the conventional cursor tracking alignment system.

Then, in FIG. 2F, when the user continues to rotate the aerial mouse device 20 to the left and points to the actual screen 12, the cursor 14 will move from the right border of the actual screen 12 to the left to the air mouse device 20 pointing to the actual The coordinate point of the screen. As can be seen from FIG. 2A to FIG. 2F, the aerial mouse device 20 provided by the embodiment of the present invention does not require the user to manually correct the aerial mouse device 20, and there is no cursor error. It should be noted that although FIG. 2A to FIG. 2F only illustrate the movement control of the cursor 14 and the virtual cursor 14' in the first axial direction, according to the above description, the cursor 14 and the virtual cursor 14' can also be used in the same manner.

[Example of a school-free cursor tracking alignment system]

Please refer to FIG. 3A. FIG. 3A is a block diagram of the school-free cursor tracking alignment system 51 according to an embodiment of the present invention.

The communication module 214 transmits the received key signal and the motion sensing signal to the receiving device 31 in a wired or wireless manner. It should be noted that in other embodiments, the button signal generator 231 and the central processing unit 232 can also be removed from the air mouse device 23.

The communication module 312 is configured to receive the key signal and the motion sensing signal wirelessly or by wire, and transmit the sensing signal to the coordinate calculating unit 311. The coordinate calculation unit 311 is configured to obtain the virtual cursor displacement amount according to the motion sensing signal, and update the coordinate point of the current virtual cursor according to the virtual cursor displacement amount and the coordinate point of the previously recorded virtual cursor. The coordinate calculation unit 311 determines whether the first axial (eg, X-axis) coordinate value of the coordinate point of the current virtual cursor exceeds the first axial boundary of the application screen (eg, the left and right boundaries), and determines the current virtual cursor. The second axial (e.g., Y-axis) coordinate value of the coordinate point exceeds a second axial boundary (e.g., upper and lower boundaries) of the application screen, wherein the first axis is perpendicular to the second axis. If the first axial coordinate value does not exceed the first axial boundary, or the second axial coordinate value does not exceed the second axial boundary, the coordinate calculation unit 311 generates a cursor movement signal; conversely, if the first axial coordinate value When the first axial boundary is exceeded and the second axial coordinate value exceeds the second axial boundary, the coordinate calculation unit 311 does not generate the cursor movement signal.

Through the announcement of the format conversion unit 313, the operating system can obtain a coordinate conversion relationship. Since the first axis and the second axis are perpendicular to each other, the first axis coordinate value x1 of the coordinate point of the actual screen 12 has a 4 to 1 ratio between the first axis coordinate value x2 of the coordinate point of the application screen 12'. The ratio is such that the second axial coordinate value y1 of the coordinate point of the actual screen 12 has a ratio of 3 to 1 between the second axial coordinate value y2 of the coordinate point of the application screen 12'.

In FIG. 5, the user initially points the aerial mouse device to the coordinate point (500, 600) of the actual screen 12, so the coordinate point of the initial cursor to the actual screen 12 is (500, 600). Then, the user moves the aerial mouse device to the right, but does not exceed the boundary of the application screen 12' (ie, the first axial coordinate value of the coordinate point of the virtual cursor does not exceed the first axial boundary of the application screen, and The second axial coordinate value of the coordinate point of the virtual cursor does not exceed the second axial boundary of the application screen, and the cursor displacements of the first and second axial cursor movement signals calculated by the coordinate calculation unit 311 are respectively +25 and 0.

Next, the user operates the aerial mouse device to move the virtual cursor 14' along the movement trajectory C0. Since the first axial coordinate value of the coordinate point of the virtual cursor 14' has exceeded the right border of the application screen 12', the cursor 14 will stay at the right border of the actual screen 12 without moving.

Thereafter, the user operates the aerial mouse device to move the virtual cursor 14' along the movement trajectory C1. When the first axial coordinate value of the coordinate point of the virtual cursor 14' has exceeded the right boundary of the application screen 12', and the second axial coordinate value of the coordinate point of the virtual cursor 14' has not exceeded the application screen 12' At the boundary, the cursor 14 moves up on the right border of the actual screen 12.

[Example of a school-free cursor tracking alignment method]

Please refer to FIG. 3A and FIG. 7A. FIG. 7A is a flowchart of a cursor tracking alignment method according to an embodiment of the present invention. The cursor tracking alignment method of FIG. 7A corresponds to the school-free cursor tracking alignment system 51 of FIG. 3A. First, in step S700, the format conversion unit 313 of the receiving device 31 announces to the computer device 41 the data format of the aerial mouse device 21, the virtual screen and the absolute coordinate range of the application screen thereof through the standard specification, wherein the virtual screen has an actual screen corresponding to the actual Screen application screen.

Then, in step S701, when the user moves the aerial mouse device 21, the motion sensing module 213 generates an action sensing signal, and the central processing unit 212 acquires the motion sensing signal, and instructs the communication module 214 to This motion sensing signal is transmitted to the receiving device 31. Then, in step S702, the communication module 312 of the receiving device 31 receives the motion sensing signal.

Next, in step S703, the coordinate calculation unit 311 of the receiving device 31 calculates the virtual cursor displacement amount according to the motion sensing signal, and updates the coordinate point of the current virtual cursor according to the virtual cursor displacement amount and the coordinate point of the previously recorded virtual cursor. . Next, in step S704, the coordinate calculation unit 311 of the receiving device 31 determines whether the first axial coordinate value of the coordinate point of the current virtual cursor exceeds the first axial boundary of the application screen and the second axis of the coordinate point of the current virtual cursor Whether the coordinate values exceed the second axial boundary of the application screen.

If the first axial coordinate value of the virtual cursor coordinate point exceeds the first axial boundary of the application screen and the current second coordinate coordinate value of the virtual cursor coordinate point exceeds the second axial boundary of the application screen, step S709 is performed; Conversely, if the coordinate point of the current virtual cursor does not meet the above conditions at the same time, step S705 is performed.
