The Computer Mouse Evolution

Did you know the first computer mouse was wooden?

  1. New input device
    The first computer mouse was created in 1963. It was designed by Douglas Engelbart. Doug Engelbart reportedly conceived the mouse during a conference lecture in 1961. His first design, in 1963, used rolling wheels inspired by mechanical area-measuring devices called planimeters invented in the 1800s.

    It should be noted that since then more than one billion computer mice have been sold in the world.

As you can see in the picture, the mouse was made of wood, was much larger than today's mouse, rectangular in size, and had a small button in the top right corner.

2. Ballpoint Mouse

The first ball-point computer mouse was created in 1968 by Telefunken Rollkugel. Instead of two wheels it used one small ball. The working principle of this mouse was the same as that of the mouse from Douglas Engelbart, but it was much more convenient to work with it. Such mice were actively used until the 2000s, until they were replaced by more convenient optical and laser mice.

3. The optical computer mouse

An optical mouse is a computer mouse which uses a light source, typically a light-emitting diode (LED), and a light detector, such as an array of photodiodes, to detect movement relative to a surface. It is an alternative to the mechanical mouse, which uses moving parts to sense motion.The earliest optical mice detected movement on pre-printed mousepad surfaces.
Whereas modern optical mice work on most opaque diffusely reflective surfaces like paper, they usually aren't able to detect movement on specularly reflective surfaces like polished stone; coherently-lit (laser) mice can function even on such glossy surfaces, but perform poorly on transparent surfaces; dark field illumination allows mice to function reliably even on glass.
Laser diodes are also used for better resolution and precision. Battery-powered wireless optical mice flash the LED intermittently to save power, and only glow steadily when movement is detected.

4. The laser computer mouse
The laser computer mouse  is an advanced version of the mouse optical. The principle of their work is similar in many aspects. The only difference is that the laser is not used to illuminate the surface. This refinement made the device almost ideal: the device works on any surface. It is more reliable and consumes relatively little energy, and the movements of the cursor correspond to the actual movement of the mouse. In addition, the laser mice are very weak illumination.
