In wired connectivity, the wire carries the data about the mouse position and button clicks to the computer. The rate at which a mouse sends data to the OS about its position and button click is called its polling rate. The mouse constantly sends data about its position. Once the mouse figures out its position, it sends the data about its position to the computer. Once the sensor records the bounce back time for a second time, the DSP (Digital Signal Processor) compares the two surface details and calculates the new mouse position. By doing this, the mouse records every surface detail. The light touches the surface and then reflects to the mouse, where a CMOS (Complementary metal-oxide-semiconductor) sensor records the bounce-back time. This emitter turns on the LED when you connect the mouse to a computer. Under the mouse, there is a LED or laser emitter, depending on the type of mouse you use. On the other hand, an older mechanical mouse uses a rubber ball to track the mouse movements. And then, the sensor compares each picture to the previous one to record the mouse movement. These optical sensors take a couple of thousand pictures every second. Most mouse nowadays uses optical sensors to record mouse movement.

Wireless Bluetooth uses a computer’s Bluetooth to transfer data.

To use the wireless USB mouse, you simply plug the USB dongle into the computer, power on the mouse and the input device is ready to use. Low battery consumption, connection over a longer distance, and lower latency are what make a wireless USB mouse so popular. This mouse operates in the 2.4 GHz frequency band to transfer data. Wireless USB MouseĪ wireless USB mouse uses a USB dongle that receives data transmitted by the wireless mouse. Is Wireless Mouse Better than Wired Mouse?īefore we get into the working principle of a wireless mouse, let us first discuss the two types of wireless mouse popular in the market.
