Abstract:
1. An interactive device comprising: a first sensor configured to receive coordinate information from a coordinate projection received directly from a projector; a first button configured to transmit a first erase signal when the first button is pressed; a second sensor configured to be placed in physical communication with a projection surface, and to receive second coordinate information from the coordinate projection of the projector reflected off the projection surface, and to transmit second coordinate information when the second sensor is pressed, wherein the second sensor is a nib extending from the interactive device; an accelerometer configured to provide angle information of the interactive device; a processor in communication with the first sensor, with the first button, with the second sensor, and with the accelerometer, the processor configured to receive the coordinate information from the first sensor, to receive the erase signal from the first button, to receive the angle information from the accelerometer, to generate first erase information based on the coordinate information, the first erase signal, and the angle information, and to generate a second erase signal based on the second coordinate information from the second sensor, wherein the first erase information is continually updated by the processor in response to the first button being continually pressed and the interactive device being moved within the coordinate projection; and a transmitter in communication with the processor, the transmitter configured to transmit, via a wireless data communication, a first delete request including the first erase information received from the processor to the projector, and a second delete request including the second erase information, wherein the transmitter is configured to continually transmit, via the wireless data communication, the first delete request including the continually updated erase information in response to the first button being continually pressed and the interactive device being moved within the coordinate projection, and wherein images projected at locations identified in the continually updated erase information are no longer projected after the first erase information and second erase information are received at the projector.
