Working principle of optical mouse ppt

The optical mouse takes microscopic snapshots of the working surface at a rate of more than 1,000 images per second. If the mouse is moved, the image changes. The tiniest irregularities in the surface can produce images good enough for the sensor and DSP to generate usable movement data.

How does the optical and laser mouse work?

An optical mouse uses an infrared LED light to illuminate the surface. A laser mouse illuminates the surface with a laser beam.

Why optical mouse is important?

Optical mice have several benefits over wheeled mice: No moving parts means less wear and a lower chance of failure. There's no way for dirt to get inside the mouse and interfere with the tracking sensors. Increased tracking resolution means smoother response.

What is optical and mechanical mouse?

Alternatively referred to as the ball mouse, the optical-mechanical or optomechanical mouse consists of a ball that rolls one of two wheels inside the mouse. Each wheel contains a circle of holes or notches, allowing an LED light to shine through and be detected by a sensor.

What are the 3 functions of a mouse?

Who invented the optical mouse?

Steve Kirsch is one of the most fascinating entrepreneurs we've been lucky enough to speak to on this show. Going back to the 1980s, he was the inventor of the optical mouse.

What is the difference between optical and wireless mouse?

The main difference between the two types of technology is in the name. An optical-based mouse utilizes an LED light source and a laser mouse uses a laser. Both illumination sources enable a CMOS sensor to quickly take photos of the surface and detect movement.

How many buttons does an optical mouse have?

Button Functionality: Optical mice come with a manufacturer setting of two buttons and one scrolling wheel or three buttons.

Which type of sensor is used in optical mouse?

Able to work on almost any surface without a mouse pad, most optical mice use a small, red light-emitting diode (LED) that bounces light off that surface onto a complimentary metal-oxide semiconductor (CMOS) sensor.

What is unique about optical mouse?

An optical mouse uses special-purpose image processing chips, as the mouse takes over 1,000 images/ps below the surface level to detect movement through reflected light changes. This allows usable movement data to be generated by the DSP and sensor.
