Four key points for choosing a photoelectric mouse

How can you choose a suitable optical mouse? What do you need to pay attention to when you buy a photoelectric mouse? This article for your detailed answer

1, click the resolution

A key factor in the performance of a mouse is the number of points per inch that can be identified by the decoding device inside the mouse, which is what people call the click Resolution. At present, a good optical mouse and its click resolution is up to 800dpi, compared with the old 400dpi mouse, in the same environment, the same settings, each one inch can be transmitted back to the 800 scan coordinate points, than 400dpi, one times higher than the normal mouse positioning can be more accurate

The effect is meticulous. As a mature mouse purchaser, the first thing to pay attention to when choosing a mouse is the click resolution of the mouse.

2, optical scanning rate

Unlike the click Resolution, the optical scanning rate as the 2nd important parameter of the photoelectric Mouse Performance index is often overlooked, simply put, the optical scanning rate refers to the mouse's light eye in each second receives the light reflection signal and converts it to the number of digital electrical signals. The mouse light eye each second can receive the scan the higher the number of times, the mouse can accurately reflect the position of the cursor movement, its reaction speed is more sensitive, there will be no cursor can not keep up with the actual movement of the mouse up and down drift phenomenon. Take Microsoft's series of Mice for example, its optical scanning rate has reached 6 million pixels/sec, and Logitech's MX700 also has 4.7 million pixels/sec, while some inferior mouse is only 2 million/sec or even lower scanning rate, which is why some users buy such a mouse feeling is always not flexible reasons to use.

3, color blindness problem

Some friends, in some specific color of the mouse pad and desktop use of optical mouse, found that their own mouse although has excellent optical scanning rate and click Resolution, but sometimes there will be a mouse, floating serves, pointer lag, trembling, drift phenomenon, thinking that their mouse is broken, in fact, the mouse is not bad, But this mouse has "color blindness", which limits its use of the environment.

For the "Light Eye" of the mouse, some photoelectric converters can only be used for some specific wavelength of shade formation induction photoelectric conversion, and can not adapt to all colors. This occurs when the mouse is used on certain colors of the desktop to show no response or missing pointers, and a mature mouse, the photoelectric converter will be the color of the sensor technology to improve, so that it can perceive the light of various colors to ensure that the desktop and materials in a variety of colors can be used normally. For example, the previous period of the sun flower using TCCB light sensing technology, made of colorless blind mouse, greatly facilitate the user, so that it can be used on any desktop smooth use.

4. Shape and Ergonomics

A good mouse is a beautiful appearance of the use of comfortable and suitable for the user hand size of the mouse, and different users should be based on their own actual situation to choose the right mouse. Generally speaking, a good mouse surface work should be delicate and smooth, the shell is smooth but not slippery hand, should not have any obvious burrs and abrupt, and seams should be delicate and fine.

Many people who use the mouse frequently will find their wrist prominent, fingers and wrist will often appear sore feeling, this shows that its mouse design does not embody the people-oriented design ideas. At present, some excellent mouse on the market fully embodies the ergonomic design idea, in the actual grip should feel relaxed and comfortable and with the palm of the face, the keys easy and flexible, and the current market, the popular 3D wheel design, it is very convenient to like to watch E-books and Web pages of users, So they don't have to move the mouse when they page and drag pages.
