Embodiment Construction
[0042] see figure 1 , figure 1 It is a schematic diagram of a computer system 10 according to an embodiment of the present invention. The computer system 10 includes a navigation device 12 , a screen 14 and a terminal device 16 . The navigation device 12 and the screen 14 are electrically connected to the terminal device 16 . Generally speaking, the navigation device 12 is an optical mouse with adjustable sampling precision, and the terminal device 16 is a host computer. Wherein, the sampling accuracy represents the number of samples (Counts Per Inch, CPI) of the navigation device 12 within a unit distance. The terminal device 16 is used to execute the application program, and can change the resolution parameter of the screen 14 according to the characteristics of the application program. At this time, the sampling accuracy of the navigation device 12 can be further adjusted accordingly with the change of the resolution parameter, so as to meet the needs of the user. opera...

The invention discloses a method for adjusting sampling precision of a navigation device, the related navigation device and a terminal device. The sampling precision represents a sampling quantity of the navigation device within a unit distance; the method comprises the following steps: judging the preset mode of the navigation device, acquiring resolution ratio parameters of a screen, and adjusting the sampling precision according to the resolution ratio parameters and the preset mode, so as to enable the sampling precision to be correspondingly increased or decreased according to the change of the resolution ratio parameters. According to the method for adjusting sampling precision of the navigation device, the related navigation device and the terminal device, the sensitivity of the navigation device can be effectively changed by utilizing the adaptive sampling precision adjusting mechanism, the comfort level of a user to use the navigation device can be increased, and further the operation convenience and the market competitiveness of the computer system can be improved.
Description
technical field [0001] The invention relates to a method for adjusting the sampling accuracy of a navigation device, in particular to a method capable of automatically adjusting the sampling accuracy and related navigation devices and terminal devices. Background technique [0002] The optical mouse utilizes the light detection unit to perform sampling to obtain the displacement and coordinate information of the optical mouse. The sampling frequency of the light detection unit can be determined according to the user's habits. For example, if the sampling frequency of the light detection unit is increased, the cursor displacement driven by the user's operation of the optical mouse is more sensitive; The cursor movement driven by operating the optical mouse is relatively slow. Generally speaking, the sampling frequency (or sampling precision) of the optical mouse can have a multi-stage adjustment mechanism, allowing the user to adjust at will according to needs. However, dur...
