Abstract

An interactive device includes a first sensor, a first button, an accelerometer, a processor, and a transmitter. The first sensor is configured to receive coordinate information from a coordinate projection of a projector. The first button is configured to transmit an erase signal when the first button is pressed. The accelerometer is configured to provide angle information for the interactive device. The processor is in communication with the first sensor, with the first button, 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, and to generate erase information based on the coordinate information, the erase signal, and the angle information. The transmitter is in communication with the processor, and is configured to transmit a delete request including the erase information received from the processor to the projector.
