An external computer mouse has a radio frequency (RF) receiver within the body of the mouse to allow remote control or access of the mouse buttons. The RF receiver is powered by the mouse power supply from a computer port. The mouse can be operated conventionally, but when a signal from an RF transmitter is received the mouse functions as if a button has been pressed. This allows a user to walk around while giving a visual presentation with a computer. |
