Claim:
1. An interactive device comprising: a first sensor configured to receive first coordinate information from a coordinate grid projected from a projector and reflected off of a projection surface, wherein the first sensor is a nib extending from a first surface of the interactive device, the first sensor is configured to be placed in physical communication with the projection surface; a processor in communication with the first sensor, the processor configured to receive the first coordinate information from the first sensor in response to the first sensor being pressed partially within the interactive device through the first surface, to generate a first erase request based on the first coordinate information, and to continually update the first erase request with incremental coordinate information in response to the first sensor being continually pressed partially within the interactive device; and a transmitter in communication with the processor, the transmitter configured to transmit the first erase request to the projector.
