Key notes

To give input commands to your PC, you need input devices such as a keyboard and mouse. While previously there was only a wired optical mouse, now thereare wireless miceas well. Have you ever wondered how does an optical mouse work? Or did this thought ever cross your mind?

If yes, then you are in the right place. In this guide, we will share with you a complete explanation of how an optical mouse work and what the features associated with it are over a wireless mouse. So let us get right into it.

What is an optical mouse?

An optical mouse is an input device that allows you to interact with the contents on your PC. It uses a LED (light emitting diode), an optical sensor, and a DSP (digital signal processor).

An optical uses its sensors to convert the movements on a surface to the direction of a cursor on the computer screen.

The optical mouse shines the light on the surface, and the optical sensor then picks up the reflected light. Thousands of images are taken every second by the optical sensor and sent to the DSP for analysis.

The digital signal processor then understands the images determining whether the mouse has moved. This includes information on whether the mouse moved left or right, up or down, and the speed at which it was moved.

This information is then sent to the computer using the cable or the wireless receiver, which then moves the cursor accordingly.

Advantages of an optical mouse

Here are some of the advantages of using an optical mouse:

Disadvantages of an optical mouse

Is an optical mouse better than a wireless mouse?

Well, let us get one thing very clear. Optical mice aren’t only available as a wired mouse. The optical mouse also ships as a wireless mouse.

The technology remains the same, but in wired mice. Although, at the same time, the transfer of information happens through a cable, in wireless optical mice, the transmission occurs via Bluetooth or a wireless receiver.

Here are a few things that will clarify whether the optical mouse is better than a wireless mouse or not.

The above comparison is between a wired optical mouse and a wireless mouse. There are other differences when you compare a laser mouse with an optical mouse.

We hope the above points helped you better understand the difference between an optical and wireless mouse.
