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 correction method for calculating the deviation of the boundary displacement of the screen cursor and performing compensation and correction of the displacement of the cursor accordingly. Background technique [0002] The input device of the computer has been developed so far, and the use of the mouse (Mouse) as the input pointing device is almost a basic equipment. The user can quickly move the cursor on the computer screen to any icon or option by moving the mouse. An input pointing device or method for cursor movement, such as a wireless pointing device, gesture recognition, or eye movement, can control the movement of the cursor. [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...

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 as an illustration, please refer to figure 1 , when the user moves the mouse 12 to move in the A1 direction, the cursor 10 on the screen 11 will also move along the A1 direction in conjunction with the input pointer until the cursor 10 reaches the border of the screen 11 and stops. If the user moves the mouse 12 Continue to move in the direction of A1. At this time, 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 at this time, the cursor 10 will immediately move in the direction of A2, so the accumulated number of times After operation, since 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 place it in the center of the mouse pad 13 again 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
