Here, we will discuss about core working principle of mechanical and optical mouse. Such as
Mechanical Mouse Working:
Here, we will spread light on some mechanical mouse working principles are:
- Mouse has to contain the rubber ball that is touch with desktop and rolls while moving the mouse.
- Two rollers are existed in the mouse, this touch with ball. One roller is placed that detect the motion in X directions; other suited 90 degrees that identify the Y direction’s motion. When roller touch ball then that is able to detect both X and Y motion.
- Every roller is associated with a shaft, and shaft allows spinning disk on its hole. Both shaft and disk spin while rolling the roller.
- Infrared LED and an infrared sensor are embedded on the mouse’s circuit board. LED spreads the beam of light, and disk breaks them. In entire process infrared sensors identify all pulses that are coming from disk after splitting. The pulse’ rate depend on the speed of mouse and it traveling distance.
- Processor access all pulses that are coming from infrared sensors and convert them into binary form such as 0 an 1 because computer only can understand binary language , and finally send to computer with the help of mouse ‘cord.
Optical Mouse Working:
Optical Mouse Working Principle – Optical mouse is totally different to mechanical ball mouse, because in optical mouse are operations are performed by LED (light emitting diode) and photo detector. Both are placed near each other. Work of photo detector is gather all beam of light and bounced off on the surface area. In photo detector, lens are embedded those collect all beams and forward to CMOS (Complementary Metal Oxide Semiconductor) sensor. Photo detector is a high speed camera and able to transfer 1500+ images in per second towards to CMOS sensor with the help of their lens.
The CMOS sensor gets all pictures with the help of digital signal processor which is also known as optical navigation engine. Optical navigation engine works as brain of mouse because it able to compute all pictures among of other different images. These images contain all information of motion, and send to computer. Finally computer can control all motion of pointer on the behalf of those coordinates.
Now, finally you have understood that optical mouse how to work smoothly.
