Adaptive adjustment method of mouse dpi and its application

Abstract

The invention provides a mouse DPI self-adaptive adjustment method and its application. Firstly, the user category is identified, and then the DPI value adapted to the user category is selected and set as the initial DPI value of the mouse. The mouse DPI value can be preliminarily selected according to the user category, the selection efficiency is high, and the amount of calculation can be significantly reduced. For different types of user categories, it is possible to have a relatively suitable mouse DPI value for primary selection. After the initial selection, the mouse DPI value is adjusted for the first time, and more than one subsequent adjustment is completed to complete the adjustment of the mouse DPI value, which can further make the mouse DPI value more suitable for the corresponding user category, and adopt optimal iteration and other algorithms in the prior art Selecting the DPI value can significantly reduce the amount of calculation, reduce the workload of the host, prevent the host from crashing or occupying a large amount of computing resources, and the adjustment time is shorter.

Description

technical field [0001] The invention relates to the field of mice, in particular to a method for adaptively adjusting mouse DPI and an application thereof. Background technique [0002] A mouse is a commonly used electronic device, wherein an optical mouse is mainly composed of four core components, namely a light-emitting component, a lens component, a photoelectric sensor, and a control chip. When the mouse moves, the photoelectric sensor records continuous patterns, and then compares and analyzes each picture before and after to determine the direction and displacement of the mouse movement, so as to obtain the movement values ​​​​of the mouse in the x and y directions, and process these values After that, pass it to the host. Among them, DPI (dot per inch) is an important characteristic parameter of the mouse. Mouse DPI refers to the positioning accuracy of the mouse. The unit is dpi or cpi. It refers to the maximum number of information that can be accurately positione...

Problems solved by technology

But in fact, through the operation efficiency, in different application scenarios, the optimal DPI required by the same task type ID is different, therefore, further making this existing technology only applicable to specific scenarios

[0008] In addition, in some existing technologies, it is necessary to wait for the host to collect a large amount of data and complete the calculation of the optimal mouse DPI value before generating instructions to adjust the DPI value of the mouse.

For a period of time before the adjustment is completed, the actual DPI value of the mouse is the DPI value before the adjustment. In addition to the calculation resources occupied by the adjustment process, if the DPI value before the adjustment does not match the demand, the mouse will still be displayed during the adjustment process. Does not match actual needs, affecting user use

[0009] In addition, in the prior art, there is only a user authentication method based on the user's mouse behavior habits, which not only requires a huge amount of data, but also is not suitable for user classification for DPI selection, and user classification methods in other fields are not suitable for user classification. User classification for DPI selection
