What is a DPI mouse? How does it affect work?

The first computer mice appeared more than 50 years ago. They were then opto-mechanical: their position on the screen was determined with the help of a ball and two rollers. Such manipulators were rather inconvenient, had little accuracy and often broke down. With the development of technology they were replaced by optical mice. Their principle of operation is based on multiple photography of the surface and Comparison of the obtained data. Based on the results of the comparison, the direction and speed of movement are determined. Optical mice have a characteristic red illumination, which is used to improve the efficiency of the sensor element. One of the varieties of the optical manipulator is the infrared sensor. This is already a bit different technologies, speed and accuracy of cursor movement. To date, the optical mouse has simply beyond the limits, in comparison with the "ancestors" characteristics.

The parameter that displays the accuracy of the manipulator and the speed of its movement across the screen is called the DPI of the mouse. It shows how many dots per inch (2.54 cm) can determine (count) this device. Therefore, the higher this value, the higher the cursor positioning accuracy. Using a laser sensor element allows you to take pictures of the surface very contrast. This allows you to increase the DPI mouse several times. If using an optical element with a maximum of 1800, then modern models using a laser can already have up to 5600. Do you need such values - decide for yourself, in this case the main thing is to decide what you are buying a mouse for. DPI at 5600 gives you the ability to overclock Manipulator to 2 meters per second, which means that it is with such speed will move the cursor on the screen. If this is what you need - buy a mouse with such parameters.

Increasing the accuracy of the guidance is good, but there is one "but": with increasing accuracy, the speed of movement of the marker on the screen also increases. This is inconvenient when working with office programs, it is not suitable for graphic editors, etc. For work in office programs, the optimal DPI of the mouse is in the range from 400 to 800. At high speeds, a considerable muscle tension is required, and the hand gets tired much faster.

Mice with large DPI values are needed for computer games. It is due to the increased requirements for speeds in modern "entertainments", these Manipulators so rapidly evolved. After all, it requires a high speed of moving the cursor across the screen, and high accuracy of its guidance.

For those who work in office programs and likes to relax with the help of games, there are models that can change the parameters. The mode and value of the DPI mouse is changed by pressing a special button under the scroll wheel. Most often this parameter varies from 200 to 3600. There are several modes of operation. In order to control the current DPI parameter of the mouse, it is possible to change the color of the backlight. This function is configured with special programs.

If before the special attention to the choice of mice were not given (they were all approximately the same), today there appeared a huge number of various models that are more comfortable, accurate or have some other features. Another thing is that to understand if this modification is convenient for you, you can only after a few days of work. But remember that by law you can change the goods or return the money within 14 days. The main thing is to keep the presentation, all documents and packaging.
