Abstract
A briefing system is used to project images onto a projection screen to form a projection picture. The briefing system comprises a pointer, a projector and a computer electrically connected to the projector. The computer outputs an image signal to the projector. The projector projects an image corresponding to the image signal onto the projection screen to form the projection picture. The indicator is used to project an indication point. The projector also captures the image of the projection picture and the indication point and transfers the image to the computer. The computer then calculates a location where the cursor on the computer screen should reach according to the location of the indication point on the projection picture and moves the cursor on the screen to there.
