Wireless clicker

A wireless clicker  or wireless presenter  is a remote control used to control a computer during a presentation, instead of a "mouse or the keyboard",. Usually it has a laser pointer inside to pintpoint parts of the screen. It is mainly used to show a computer presentation created with PowerPoint using a video projector and allows the presenter to move freely in front of the audience. 

An RF pointer-mouse consists of a transmitter similar to a remote control ­used in a Television set and a small receiver, usually connected to a USB port on the computer..  

 Included elements 

 USB memory and timer 

Among other additional elements there can be a built-in flash memory in the USB receiver, so that there is no need to plug in an additional flash drive to carry the presentation file. Some models include a vibration alarm, to notify the speaker when time is up

 Laser pointer 

Apart from the elements to control the presentation, the clicker transmitter often contains a laser pointer. A distinguishing feature among the models offered is the color of the laser. For presentations green laser is more visible than red laser.
