Description

Self-adaptive adjusting method of mouse DPI and application thereof
Technical Field
The invention relates to the field of mice, in particular to a self-adaptive adjusting method of a mouse DPI and application thereof.
Background
The optical mouse is a commonly used electronic device, wherein the optical mouse mainly comprises four parts of 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, then the front and back comparison analysis processing of each picture is carried out to judge the moving direction and displacement of the mouse, so as to obtain the moving numerical values of the mouse in the x and y directions, and the numerical values are transmitted to the host after being processed. Wherein, DPI (dot per inch) is an important characteristic parameter of the mouse, DPI of the mouse is the positioning precision of the mouse, and the unit is DPI or cpi, which means the maximum information number that can be accurately positioned every inch of movement of the mouse. DPI is the number of points per inch, i.e., the number of points a pointer moves on the screen per inch of mouse movement.
The mouse in the prior art does not provide a DPI adjusting function, so that when a user actually uses the mouse, the DPI of the mouse needed by different scenes is not consistent, for example, when the user plays a game, the mouse needs to have a very high DPI, and when the user performs a drawing operation, the DPI needs to be lower. The DPI adjustment is to achieve the effect of adjusting the sensitivity of the mouse by adjusting the sampling frequency of the sensor so as to adapt the mouse to different working requirements. In the conventional technology, a user can only adjust the DPI of the mouse through a device manager on a host, so that the burden of the user is increased, the DPI is still fixed after adjustment, the flexibility is poor, the user can only adjust the DPI according to self feeling or subjective prediction, and the adjustment effect cannot achieve the expected purpose.
Aiming at the technical problem, the prior art provides an automatic mouse DPI adjusting method and a speed self-adaptive mouse capable of identifying different task types. The task environment used by the user is judged, the DPI value is automatically selected, namely the adaptive mouse speed is automatically selected, so that the requirements of the user on different tasks are met, the operation precision of a specific task can be improved, the operation time is shortened, the physical distance for the user to move the mouse is reduced, and fatigue is relieved.
However, the prior art has obvious defects, for example, different requirements of different types of users on the mouse DPI are not considered, and in practical situations, the number of task type users is usually multiple, uncertain and difficult to predict, so that the automatic adjustment method is applicable to few users, and is mostly an automatic adjustment method for the mouse DPI of a specific user in some specific professional fields.
In addition, in the prior art, for each task type, the gradient is adjusted by taking a specific value as the DPI, a user is required to test the operation efficiency under different gradients respectively according to the specification, and the workload is large and time-consuming for the user. In the prior art, the optimal mouse DPI value is solved through algorithms such as traversal or iteration, the calculated amount is large under the conditions of more parameters, larger data volume and the like, so that the calculation resources of a host are greatly occupied, the normal work of the host is influenced, and the host is halted or a long time is needed to obtain the solving result if serious conditions exist.
Further, in the prior art, the task type ID is determined by the ferz's law log2(D/W +1), and then the optimal DPI is tested for each task type ID to maximize the mouse operation efficiency. In practice, however, the optimal DPI required for the same task type ID is different in different application scenarios through operational efficiency, thus further making this prior art applicable only to specific scenarios.
In addition, in some prior art, the host needs to collect a large amount of data and complete the solution of the optimal mouse DPI value, and then generates an instruction to adjust the DPI value of the mouse. In a period of time before the adjustment is completed, the actual DPI value of the mouse is the DPI value before the adjustment, except that the adjustment process occupies computing resources, if the DPI value before the adjustment is not matched with the requirement, the mouse is still not matched with the actual requirement in the time during the adjustment process, and the use of a user is influenced.
In addition, in the prior art, only the user authentication method based on the behavior habit of the user mouse is used, so that the required data volume is extremely large, the method is not suitable for user classification aiming at DPI selection, and the user classification methods in other fields are not suitable for user classification aiming at DPI selection.

Specifically, in step S35, the step of correcting the DPI value of the mouse according to the slope of the fitted straight line includes:
if the slope of the straight line obtained by fitting is less than 0, reducing the DPI value of the mouse by a preset decrement;
if the slope of the straight line obtained by fitting is greater than or equal to 0 and smaller than a preset slope threshold value of the straight line, maintaining the current DPI value of the mouse;
and if the slope of the straight line obtained by fitting is larger than the threshold value of the slope of the preset straight line, increasing the DPI value of the mouse by a preset increment.
Illustratively, the preset straight-line slope threshold is 0.1. It should be noted that, for different users and different scenes, the preset slope threshold of the straight line may be changed.
Therefore, the DPI value of the mouse can be adjusted according to the speed change rule when the user operates the mouse, and compared with the prior art, the adjustment result is more fit with the actual situation. Specifically, when a user normally operates a mouse, along with the improvement of proficiency of the real-time program D0, for the movement of the mouse with a linear track and an approximate linear track, if the speed of the mouse is kept unchanged or slightly increased, the normal rule can be determined, it is indicated that the initial DPI value of the mouse selected according to the user category meets the user requirement and the operation habit, the slope of the straight line obtained by fitting is greater than or equal to 0 and smaller than a preset slope threshold value, and the mouse can maintain the current DPI value, that is, the DPI value of the mouse does not need to be adjusted. If the slope of the straight line obtained by fitting is less than 0, it indicates that although the proficiency level of the real-time program D0 is improved, the speed of moving the mouse by the user is reduced, and it can be determined that the user emphasizes the requirement on the operation precision in the real-time program D0, and the DPI value of the mouse can be reduced by a preset decrement, so that the DPI value of the mouse is more adaptive to the requirement of the user. If the slope of the straight line obtained by fitting is greater than the preset slope threshold value, it indicates that the proficiency level of the real-time program D0 is improved, but the mouse moving speed of the user is gradually increased, and it can be determined that the user emphasizes the requirement on the mouse moving speed in the real-time program D0, the DPI value of the mouse is increased by a preset increment, so that the DPI value of the mouse is more adaptive to the requirement of the user.
S4: and according to the method of the step S3, the DPI value of the mouse is adjusted for more than one time, and the adjustment of the DPI value of the mouse is completed. By carrying out more than one subsequent adjustment on the DPI value of the mouse, the adjustment result of the DPI value of the mouse can be corrected for the second time, and the adjustment accuracy is improved.
In this embodiment, the adjustment of the DPI value of the mouse is completed by performing the first adjustment and the more than one subsequent adjustment on the DPI value of the mouse after the initial selection. On one hand, compared with the initial selection, the mouse DPI value can be further more adapted to the corresponding user category by adjusting the mouse DPI value more than twice. On the other hand, compared with the prior art that the DPI value is selected by adopting the algorithms such as the optimal iteration and the like, the technical scheme of the invention can obviously reduce the calculation amount, thereby reducing the workload of the host and avoiding the host from crashing or occupying a large amount of calculation resources.
The embodiment also provides a computer system combining a mouse and a host, which is used for realizing the self-adaptive adjusting method of the mouse DPI of any scheme.
The detection module is used for acquiring real-time coordinates of the mouse according to a preset sampling frequency f, the first communication module is used for sending acquisition information of the detection module to the host through the second communication module, the host is used for generating a control instruction for controlling the DPI of the mouse according to the self-adaptive adjustment method of the DPI of the mouse in any scheme, and the execution module is used for adjusting the DPI of the mouse according to the control instruction of the host.
