Problems solved by technology

Although the computer also has a program to adjust the mouse sensitivity (that is, the scanning accuracy), the mouse sensitivity needs to be set once before playing the game, and the mouse sensitivity cannot be adjusted synchronously during the game.
The game itself may require the mouse to have different response speeds for different scenes. For example, fierce confrontation scenes such as war require the mouse to respond quickly. During sexual scenes, the range of mouse movement is too large, which is not suitable for the player's mood
This requires that the adjustment of the mouse scanning accuracy can be realized without exiting the game process, and the existing technology cannot meet this requirement

Embodiment Construction

[0023] Below in conjunction with accompanying drawing and embodiment the present invention will be further elaborated:

[0024] The method of the invention realizes by linearly increasing the movement data collected from the optical IC through software. On the basis of the relatively fixed standard DPI (400DPI, 800DPI) of the current display, the DPI of the optical sensor of the mouse is increased. When playing games, the mouse moves the same unit size, and the cursor moves on the screen. The distance is greater, and the speed of the mouse and Faster response makes the mouse a winning weapon for gamers. For example: the selected optical sensor is Agilent's ADNS-3060, such as figure 1 As shown, the scanning accuracy of ADNS-3060 itself is 800DPI, but the mobile data collected from the optical sensor can be linearly increased by software to achieve 1000DPI, 1000DPI is 1.25 times of 800DPI, so the mobile data is multiplied by 1.25, so that The processing speed is accelerated, a...

Abstract

Photoelectrical mouse includes light emitting diode, set of lens for receiving beam reflected from plane of placing mouse, and optical inductor for receiving beam from the set of lens and determining position of mouse. Characters are that the disclosed mouse also includes key button for decreasing scanning precision, key button for increasing scanning precision, and calculator of scanning precision, and DSP in optical inductor. Based on initial value of mouse scanning precision, decreasing and increasing commands, final value of calculated scanning precision is output. Game player can adjust scanning precision of mouse without need of exiting from game so as to meet requirements of different sensitivities of mouse.

Description

[technical field] [0001] The invention relates to the technical field of computers, in particular to a photoelectric mouse with variable scanning precision. [Background technique] [0002] The working principle of the existing photoelectric mouse is: there is a light-emitting diode inside the photoelectric mouse, and the light sent by the light-emitting diode illuminates the placement plane at the bottom of the photoelectric mouse such as the surface of the mouse pad (this is why the bottom of the mouse always emits light) ). Then part of the light reflected back from the plane on which the bottom of the photoelectric mouse is placed passes through a set of optical lenses and is transmitted to an optical sensing device (micro imager) for imaging. In this way, when the photoelectric mouse moves, its moving track will be recorded as a set of coherent images shot at high speed. Then use a dedicated image analysis chip (DSP, digital microprocessor) inside the photoelectric mou...
