一种鼠标DPI自动调整方法及速度自适应鼠标A mouse DPI automatic adjustment method and speed adaptive mouse

技术领域technical field

本发明属于计算机信号输入设备领域，尤其涉及一种可根据不同任务而速度自适应的鼠标及其DPI自动调整方法。The invention belongs to the field of computer signal input devices, in particular to a mouse whose speed can be self-adapted according to different tasks and a DPI automatic adjustment method thereof.

背景技术Background technique

随着鼠标技术的发展，尤其是鼠标性能的改善，鼠标DPI(DotsPerInch，每英寸的像素数)有显著的提高。当我们需要鼠标在屏幕上移动一段固定的距离时，高DPI的鼠标所移动的物理距离会比低DPI鼠标要短。高DPI的鼠标可以对更小的操作在最快的时间里做出反应。但是，现在用户使用鼠标时会面对很多不同的任务，这些任务可能需要鼠标对于不同的任务有特定的速度。有的任务需要频繁的大幅移动鼠标，这就需要鼠标速度较快。有的任务需要对目标进行细微操作，这就需要将速度降下来以提高精度。针对这一问题，申请号为200710076440.5的发明专利提出预设不同的DPI让用户针对不同的任务手动调节鼠标速度，而这种解决方案在用户手动调节DPI时占用了用户的时间，从而降低了工作效率。申请号为200910221384.9的发明专利提出了一种根据鼠标移动速度改变鼠标DPI的方法，但这种方法在实施过程中，容易出现鼠标DPI调节并不适合具体任务的问题，造成指针容易越过目标，从而降低操作效率。With the development of mouse technology, especially the improvement of mouse performance, mouse DPI (DotsPerInch, the number of pixels per inch) has been significantly improved. When we need the mouse to move a fixed distance on the screen, the physical distance moved by a high-DPI mouse will be shorter than that of a low-DPI mouse. A high-DPI mouse can respond to smaller operations in the fastest time. However, today's users are faced with many different tasks when using a mouse, and these tasks may require the mouse to have a specific speed for different tasks. Some tasks require frequent large-scale movement of the mouse, which requires a faster mouse speed. Some tasks require subtle manipulation of the target, which requires slowing down to improve accuracy. In response to this problem, the invention patent with the application number 200710076440.5 proposes to preset different DPIs to allow users to manually adjust the mouse speed for different tasks, and this solution takes up the user's time when the user manually adjusts the DPI, thereby reducing the workload. efficiency. The invention patent with application number 200910221384.9 proposes a method of changing the mouse DPI according to the moving speed of the mouse. However, during the implementation of this method, the problem that the mouse DPI adjustment is not suitable for specific tasks is likely to occur, causing the pointer to easily cross the target, thus reduce operational efficiency.
