The history of mouse development

The corresponding technology was also invented once the mouse was formally introduced to the PC. The technology that relied on different resistance to the position was fully abandoned and replaced by a pure digital technology mechanical mouse. The main difference between this mechanical mouse and the first-generation mechanical mouse wheel is that the bottom has a round gel sphere instead of the original vertical section of the circular wheel.

The mouse wheel invented by Microsoft in 1996 is a key invention in the history of mouse development; currently, the wheel is one of the standard mice. 1999 saw the birth of the optical mouse, which has exceptional flexibility and does not require cleaning, making it one of the most amazing mouse products. In the year 2000, the market appeared without a specific mouse pad optical mouse, and it quickly became popular.

The optical mouse (also known as “optical mouse”) detects the relative movement of the mouse for a surface using a light-emitting diode and a photodiode, as opposed to the mechanical mouse, which uses the rotation of the mouse ball to drive two mutually perpendicular axis rotations to determine the position of the mouse movement.

When the mouse moves, the DSP compares the image signal to the last sample cycle’s recorded picture and sends a displacement distance signal to the interface circuit. The interface circuit integrates and processes the displacement signal sent by the DSP, and the displacement signal passed into the computer is further processed by the driver to generate the system’s cursor displacement.

The first optoelectronic mouse required a pre-printed mouse pad surface to detect mouse movement, and now the optoelectronic mouse cannot detect mouse movement if it works on a transparent surface (such as a glass mirror). It can attain higher resolution and precision by using a laser diode. The light-emitting diode will only light up steadily when motion is detected when using a battery-powered wireless optoelectronic mouse by intermittently flashing the optical component to save electricity.
