Embodiment Construction

[0028] The present invention provides a trackball sensitivity adjustment method. In order to make the object, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] A trackball sensitivity adjustment method, such as figure 1 As shown, it includes the following steps:

[0030] A. Set a time window 110 for adjusting sensitivity, such as figure 2 shown;

[0031] B. The trackball generates a motion trajectory, and the output pulse signal 100 triggers an interruption, such as figure 2 shown;

[0032] C. Judging whether the trajectory of the trackball is valid according to the size of the time window 110, if the trajectory is valid, then send a corresponding trajectory message to the system; if the trajectory is invalid, interrupt an...

Abstract

The invention discloses a method for adjusting the sensitivity of a trackball. A time window for adjusting the sensitivity is arranged, whether the movement track of the trackball is effective or not is judged according to time difference between the time window and interrupt time, and not all track messages of the trackball are sent to a system, so that untimely processing of the system when the trackball rapidly moves and influence on user experience when the trackball slowly moves are avoided. By the aid of the time window similar to a filter, the trackball only can send a fixed number of track messages to the system within fixed time, so that the number of the track messages processed by the system is extremely uniform instead of being too large or too small, the system can timely process each track message, and a user can obtain good experience.

Description

technical field [0001] The invention relates to the field of trackball debugging methods, in particular to a trackball sensitivity adjustment method. Background technique [0002] Trackballs are now being used in many instruments, such as computer mice or control devices for other medical equipment. When the trackball is working, the ball is on the top, and the ball seat is fixed by hand, so the trackball takes up little space. It is mostly used in portable machines such as notebook computers. The trackball generally has two buttons, one for the user to click. or double-click, while the other provides the actions required for selecting menus and dragging objects. The trackball has a novel appearance, can be placed at will, and feels good after use. Its biggest advantage is that it does not need to move around like a mechanical mouse when using it, which saves space and reduces the fatigue of the user's wrist. Therefore, the market prospect of the trackball is very good. ...
