Abstract: The present invention discloses an electronic whiteboard capable of simultaneous writing and projection storage, including two groups of infrared camera modules which are mirror-symmetrical and separate an electronic whiteboard body into a left-region electronic whiteboard and a right-region electronic whiteboard. A first projector connected to the left-region electronic whiteboard/right-region electronic whiteboard is disposed at the top of the left-region electronic whiteboard/right-region electronic whiteboard. A touch mainboard of the left-region electronic whiteboard/right-region electronic whiteboard without the first projector is connected to a computer host of the electronic whiteboard computer. The computer host is connected, through the first projector, to the touch mainboard of the left-region electronic whiteboard/right-region electronic whiteboard that is provided with the first projector. The interaction effect on and off the stage are enhanced.

Abstract: The present utility model discloses a non-edge projection and integrated touch electronic whiteboard, comprising: an electronic whiteboard, infrared cameras, a touch mainboard, and a computer. A frame is disposed around the electronic whiteboard. An inner side wall of the frame is provided with an optical reflection strip. The computer separates the electronic whiteboard into a left writing area, a right writing area, and an intermediate touch area. Two infrared cameras are disposed on a same end of an upper frame and a lower frame of the intermediate touch area. The infrared cameras face the intermediate touch area.

Abstract: The present invention discloses a touch electronic whiteboard with automatic recognition for video switching. A computer host is built in an electronic whiteboard body. A HUB integrator is disposed on a frame of the electronic whiteboard body. A projector is disposed above the electronic whiteboard body. A video switching control module is built in the frame of the electronic whiteboard body. The video switching control module comprises a level detection circuit and a control chip that are connected to each other. The level detection circuit is connected to the HUB integrator. The control chip is separately connected to the projector and the computer host.
