Answer:
laser point
remote control
Step-by-step explanation:
The tools that give the presenters more freedom to move about the room and interact with their audience are:
-Laser point: is a small device that has a visible light which allows the presenter to highlight things from any place where he is.
-Remote control: Is a device that helps the presenter to control the projector from the distance to handle what's being showed in the presentation which gives him/her the liberty to move as the presenter won't have to stand next to the computer.
