Problems solved by technology

However, the traditional technology of fixed transmission rate may cause graphics distortion due to the large motion track under the environment of using higher resolution settings
When the wireless mouse is operated under high-resolution settings (that is, when the mouse moves and generates a large displacement vector value at a fixed time interval), the moving track displayed on the screen is difficult to faithfully represent the actual moving track of the mouse. causing severe distortion

Embodiment Construction

[0014] When moving a wireless pointing input device (such as a wireless mouse, trackball, touchpad, joystick, etc.) along a circular trajectory, if the sensor of the wireless pointing input device (such as an optical sensor, a laser sensor, etc.) (e.g. 400cpi), the moving track on the screen appears relatively small (e.g. Figure 1A shown). However, on the premise that the wireless pointing input device moves along the same track at the same speed, when the sensor of the wireless pointing input device operates at a higher resolution (for example, 800cpi), the moving track on the screen appears larger (eg Figure 1B shown). From the two figures, it can be seen that although Figure 1B The large polygon of is only Figure 1A Scaled up versions of small polygons, however large polygons look much less like circles. This is because the sides of the large polygon are twice as long as the sides of the small polygon. Therefore, when the sensor of the wireless pointing input device ...

Abstract

The invention discloses an operation method for a wireless pointing input device, comprising the following steps that: a displacement vector of the wireless pointing input device is tested by an analyzing degree; the displacement vector of the wireless pointing input device is transmitted to a main frame in a wireless mode in each period of time; if the analyzing degree increases, the time interval is correspondingly reduced; if the analyzing degree decreases, the time interval is correspondingly increased.

Description

technical field [0001] The present invention relates to a wireless pointing input device, and in particular to an operation method of the wireless pointing input device. Background technique [0002] When the pointing input device wirelessly transmits data to the host, due to considerations of bandwidth and power consumption, the traditional technology is to make the wireless pointing input device return data packets to the host at a fixed rate. For example, in the application of the mouse used by the computer, the wireless mouse usually returns the coordinate displacement data packet to the computer at a fixed rate to display the moving track of the wireless mouse. Recently, optical (or laser) sensors have multiple resolutions available for setting. Users can select their preferred resolution by operating switches or special buttons. Figure 1A and 1B It is to illustrate moving the wireless mouse along a circular trajectory, and the movement trajectory displayed on the sc...
