Offset correction method of cursor position

Abstract

The invention discloses an offset correction method of a cursor position, comprising the following steps of: deciding whether to transmit the displacement for controlling a cursor to move or not according to the position of the cursor on the screen of a host and the displacement of an inertial sensing signal; if the cursor exceeds the boundary of the screen, recording the boundary deviation quantity; and carrying out the relative position error compensation when the cursor rotates reversely, and moving the cursor or providing the change on the resolution of the screen after the cursor position enters into a coordinate system of the screen.

Description

Technical field [0001] The present invention relates to a method for correcting the deviation of the cursor position, in particular to a method for calculating the deviation of the boundary displacement of the cursor on the screen, and performing compensation and correction of the displacement of the cursor accordingly. Background technique [0002] Since the development of computer input devices, the use of a mouse as an input pointing device is almost the basic equipment. The user can quickly move the cursor on the computer screen to any icon or option by moving the mouse. At present, many controls have been developed. The cursor movement input pointing device or method, such as a wireless pointing device (Wireless pointing device), gesture recognition, or through eye movement, can all control the cursor movement. [0003] However, no matter what input pointing device is used to control the movement of the cursor, there is a long-standing problem, that is, after a period of use, ...

Problems solved by technology

[0003] However, no matter what kind of input pointing device is used to control the movement of the cursor, there is a long-standing problem, that is, after a period of use, the displacement deviation between the input pointing device and the cursor will cause inconvenience to the user due to the accumulation of errors. Take the commonly used input pointing device-mouse for illustration. Please refer to FIG. 1. When the user moves the mouse 12 to move in the direction of A1, the cursor 10 on the screen 11 will also move along the direction of A1 in conjunction with the input pointer until the cursor 10 When it reaches the border of the screen 11 and stops, if the user continues to move the mouse 12 in the direction of A1, the cursor 10 on the screen 11 is still at the border of the screen 11, but if the user moves the mouse 12 in the direction of A2 , then the cursor 10 immediately moves in the direction of A2. After so many times of operation, because the position of the mouse 12 gradually deviates from the mouse pad 13, the user begins to feel uncomfortable, and must pick up the mouse 12 from the mouse pad 13 and start again Place it in the center of the mouse pad 13 to continue the operation of the cursor

[0004] Other input pointing devices also have the same problem when controlling the cursor. For example, the wireless pointing device is widely used in the market. In addition to being used in general computer operations, it is currently widely used in the operation of computer interactive games, such as For interactive games such as Wii or PS2, the wireless pointer is already a must-have accessory. Usually, after the player uses the wireless pointer for a period of time, the position of the wireless pointer and the cursor will also shift. At this time, the player must interrupt the game. , after repositioning the wireless pointer and the cursor on the screen, the game that was interrupted just now can be resumed, so it is not only difficult to use, but also greatly affects the quality of the game
