Interactive projector system and method

A first image projecting device of handheld size, comprising:

• a control unit;
• a projector operable to project a first image;
• a position indicating emitter operable to project a first position indicator on a display surface;
• a wireless transceiver operable to transmit a first message;
• and
• an image sensor operable to view the display surface and detect a second position indicator from a second image projecting device,
• wherein the control unit modifies the first image projected by the projector based upon the detected second position indicator from the second image projecting device.

A method of integrating the operation of a first image projecting device and a second image projecting device, the method comprising:

• generating a first image from a first projector of the first image projecting device;
• generating a position indicator from a position indicating emitter of the first image projecting device;
• transmitting a message from a first wireless transceiver of the first image projecting device;
• operating an image sensor of the second image projecting device to detect the position indicator;
• and
• modifying a second image from a second projector of the second image projecting device based upon the detected position indicator.

A first image projecting device of handheld size, comprising:

• a control unit;
• a projector operable to project a first image controlled by the control unit;
• a position indicating emitter operable to project a first position indicator on a display surface;
• an image sensor operable to view the display surface and detect a second position indicator from a second image projecting device;
• and
• a wireless transceiver operable to receive a message from the second image projecting device,
• wherein the control unit modifies the first image projected by the projector based upon the detected second position indicator and the message received from the second image projecting device.
