Mouse is one of the most important peripheral for computers, especially for those which are not touch screen based. Fascinating is the concept that how various types of computer mice are available depending on the need, shape, pointing technology etc. There was a time when only ball mouse was prevalent. A proper surface was…
Insight – How Computer Optical Mouse works
The replacement of conventional ball mouse by the technically superior optical mouse is not hidden to anybody. An optical mouse works by having a low resolution camera inside it which takes around 1500 to 6000 pictures per second of the surface beneath it, and by analyzing these images, it calculate the position, speed and movement of the mouse.When a mouse is connected with the computer, a red LED starts glowing. This light is focused on the surface beneath the mouse by a special type of lens (HDNS-2100). The reflected light falls back to the camera integrated in Optical Mouse Sensor. The camera takes images of the surface with a frequency in the range of 1500 to 6000 images per second to calculate the position of mouse.
