Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] MCU (memory control unit) is essentially a single-chip microcomputer, which refers to a chip-level computer that integrates the computer's CPU, RAM, ROM, timer counter and various I / O interfaces on a chip.

[0037] "Air Mouse" is a device that controls the movement of the cursor through the spatial displacement of the mouse. Its convenience does not require a desktop, and it can bring a better sense of body to the operator especially in games.

Abstract

A mouse and method for automatic DPI adjustment, comprising a displacement module, an MCU and a DPI module; the displacement module is used to obtain the displacement information of the mouse, and according to the displacement information, a cursor movement track of the maximum displacement is formed on the display; the DPI module is used to record the displacement of the mouse The initial value of DPI, record it as N, and adjust the DPI value of the mouse; the MCU obtains the number of pixels corresponding to the cursor movement track, which is recorded as M1, obtains the number of pixels of the diagonal or horizontal line of the display, and records it as M2, The MCU sets the optimal value of DPI to M2 / M1*N, and controls the DPI module to adjust. This method adjusts the DPI value after fully considering the factors of the user and the monitor, which solves the problem of manual adjustment and the optimal configuration of DPI on different monitors for operators of different sizes and usage habits.

Description

technical field [0001] The invention relates to the technical field of mouse equipment, in particular to a mouse with automatic DPI adjustment and a method thereof. Background technique [0002] Existing mouse includes light-emitting diode, lens group, optical sensor and control chip; The change of the reflected image; the optical sensor is electrically connected with the control chip, and the changed light image signal is transmitted to the control chip, and the control chip modulates the signal into a form that can be read by the computer processor, and outputs the signal to the computer to control the display The cursor moves. [0003] Usually, the user selects an appropriate DPI value (that is, the number of pixels that the mouse cursor moves on the display when the mouse moves one inch) to operate the mouse according to the size of the display screen and its resolution (that is, the pixels of the display screen). According to the different optical sensors used in the ...
