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. The computer moves the mouse cursor using the received mouse movement data.The mouse sends this movement data to the computer using a transmitter.The mouse records its current position using LED or laser light.Three things are constantly occurring when you physically move the mouse: Furthermore, it also does not support connection over longer distances compared to a wireless USB mouse.īluetooth also uses a 2.4 GHz frequency band to transfer data like a wireless USB mouse.

The Bluetooth wireless mouse usually suffers from higher latency and higher battery consumption compared to the wireless mouse using USB connector. Once you pair both the devices, you can use it to move the mouse cursor. To use a wireless Bluetooth mouse, you first need to pair it with your computer’s bluetooth. 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.
