An interactive presentation control system includes a computer, a projection screen, a computer-controlled projector, and a presentation control device. The projector projects images generated by the computer onto the projection screen. The presentation control device includes a storage unit, an image capturing unit, and a processing unit. The storage unit stores a control table recording relationship between gesture shadow patterns and control commands Each gesture shadow pattern corresponds to one control command. The image capturing unit captures an image of the projection screen periodically. The processing unit processes the captured image to determine whether the captured image includes a gesture shadow pattern, and determine the corresponding control command if the determined gesture shadow pattern is recorded in the control table. The processing unit further generates a control signal corresponding to the determined control command, and transmits the control signal to the computer through the communication unit. |
