Use of Wireless Optical Pen and Mouse
A wireless optical pen and mouse are devices that can be used to interact with a computer or other device without the need for a physical connection. The pen is typically used for drawing or writing on a tablet or other surface, while the mouse is used for pointing and clicking on items on a computer screen. Both devices use optical technology to track movement and communicate with the computer, eliminating the need for a physical connection such as a USB cable. This allows for greater flexibility and freedom of movement when using the devices.
