Laser pointers tend to jitter all over the screen -especially in the hand of a nervous presenter.
Today’s invention is a laser pointer which allows the shaky presenter to press a button when the red dot is roughly in the right place.
Motion sensors in the pointer then lock the beam onto that location -shining the laser at that point irrespective of where the presenter’s hand is wandering (within reason).
Another button press and the pointer can be (unsteadily) moved to the next required location.
