Description
Technical Field
The invention relates to the field of mice, in particular to a method for improving DPI of a mouse sensor.
Background
The DPI of a mouse refers to the number of pixels of the mouse that the pointer moves on the screen every inch of movement of the mouse, which characterizes the positioning accuracy of the mouse. Such as a 400DPI mouse, which moves one inch, the pointer on the screen can move 400 pixels.
When the mouse is required to move a fixed distance across the screen, the physical distance moved by a high DPI mouse will be shorter than a low DPI mouse, which can reflect smaller operations in the fastest time. For example, in a first person-named shooting game (FPS game), when a sudden sharp turn is needed, the 800DPI mouse will take twice less physical displacement than the 400DPI mouse, so that it is easier to catch the chance of killing the enemy in the first time. Perhaps one might say that for a low DPI mouse, accelerating the mouse up by a small amount could solve the above problem. However, this reduces the positioning accuracy of the mouse. If the physical point moved by the mouse corresponds to a logical point on the screen, and originally one physical point corresponds to one logical point, under the influence of starting acceleration, a pointer ignores a part of the logical points in order to keep up with the moving speed of the mouse. Thus, it becomes possible that one physical point corresponds to a plurality of logical points, and the accuracy naturally decreases. This is not the case with high DPI mice. High DPI mice can provide nearly perfect accuracy as well as momentary acceleration, which is not done with low DPI mice anyway. Therefore, the mouse with the high DPI can bring better experience effect to the mouse user with the requirement.
The DPI of the mouse is not constant, and the DPI index of the mouse cannot be kept high all the time. When the moving speed of the mouse is slower, the value of the DPI is very low; when the moving speed is increased, the DPI value is increased. That is, the DPI is proportional to the moving speed of the mouse. All of this requires an accurate determination of the speed of movement by means of an optical sensor in the mouse.
Although the DPI value of the mouse in the prior art can reach 4000 to 6000, with the development of technology, various industries have made higher demands on the DPI of the mouse. In order to solve this problem, it is necessary to develop a method for effectively improving the DPI of the mouse.
Disclosure of Invention
The technical problem to be solved by the invention is to overcome the defects of the prior art and provide a method for improving the DPI of the mouse sensor, which has simple steps and good effect.
The technical scheme adopted by the invention is as follows: the method comprises the following steps:
(1) setting a multiplication value which is greater than 1 and has a decimal part;
(2) in the process of moving the mouse, multiplying the coordinate value of the mouse at the current time point by the multiplication value set in the step (1) to obtain a new coordinate value containing an integer part and a decimal part, and sending the integer part of the new coordinate value to a statistic device while the decimal part is reserved;
(3) multiplying the coordinate value of the mouse at the time point by the multiplication value set in the step (1) at the next set time point to obtain a new coordinate value containing an integer part and a decimal part, sending the integer part to a statistics device for accumulation, and accumulating the decimal part reserved and the decimal part reserved at the last set time point;
(4) repeating the step (3), when the integral part appears after the decimal part is accumulated, sending the integral part to a statistics device, and continuously retaining the decimal part;
(5) and outputting the integral part accumulated in the counter as an actual coordinate value until the mouse stops moving to obtain the coordinate output of the mouse optical sensor after the DPI is improved.
In the step (1), the range of the set multiplication value is 1.2-2.8.
The invention has the beneficial effects that: the invention sets a multiplier value with a decimal part and limited size, multiplies the coordinate value with the multiplier value at a set time point, then accumulates the integral part of the obtained result, and accumulates the decimal part, when the integral part appears after the decimal part is accumulated, the integral part is added into the accumulator immediately, and the decimal part is kept to be accumulated with the decimal part in the multiplied coordinate value at the next time point continuously until the mouse stops moving, the integral coordinate value obtained after the statistics device is accumulated is taken as the actual coordinate to be output, here, the multiplied decimal part is accumulated, the obtained integral part is also accumulated to the statistics device, thereby improving the final value of the statistics device and realizing the improvement of the DPI of the mouse sensor. Therefore, the method has simple steps and good DPI improvement effect.
Detailed Description
The method comprises the following steps:
(1) setting a multiplication value which is greater than 1 and has a decimal part;
(2) in the process of moving the mouse, multiplying the coordinate value of the mouse at the current time point by the multiplication value set in the step (1) to obtain a new coordinate value containing an integer part and a decimal part, and sending the integer part of the new coordinate value to a statistic device while the decimal part is reserved;
(3) multiplying the coordinate value of the mouse at the time point by the multiplication value set in the step (1) at the next set time point to obtain a new coordinate value containing an integer part and a decimal part, sending the integer part to a statistics device for accumulation, and accumulating the decimal part reserved and the decimal part reserved at the last set time point;
(4) repeating the step (3), when the integral part appears after the decimal part is accumulated, sending the integral part to a statistics device, and continuously retaining the decimal part;
(5) and outputting the integral part accumulated in the counter as an actual coordinate value until the mouse stops moving to obtain the coordinate output of the mouse optical sensor after the DPI is improved.
In the step (1), the range of the set multiplication value is 1.2-2.8, and through experiments, the multiplication value is set between the ranges, so that different multiplication values can be set according to the use effect requirements of different mouse optical sensors (sensors).
For example, as shown in the following table, which shows the multiplication process of the method of the present invention.
The first column in the table is a set time point (in this embodiment, 1ms is used as a time interval), the multiplication value is 1.2, the actual output of the optical sensor of the mouse is 56 in 16ms, and the integrated value after multiplication is 67.2. After the method of the invention, the actual cumulative output is 67, which is very close to the multiplied actual value.
For the mouse in the prior art, if the original DPI value is 5000, the multiplication value is 1.2, and the DPI value of 6000 can be obtained. If the multiplication value is 1.6, the final DPI is raised to 8000. Therefore, the DPI value of the mouse sensor can be effectively improved.
