Electronic device for erasing contents on a writing board and a method thereof

A method for erasing contents on a writing board using an electronic eraser, the method comprising:

• detecting, by a motion detector configured in the electronic eraser, movement of the electronic eraser from a resting position;
• transmitting, by the motion detector, an activation signal to activate a processor and a proximity sensor upon detecting the movement of the electronic eraser;
• sensing, by the proximity sensor, proximity of the electronic eraser with the writing board;
• displaying, by a user interface, a plurality of colors to enable selection of one or more colors of the plurality of colors by a user;
• receiving, by the processor, a signal from the proximity sensor when the electronic eraser is proximal to the writing board;
• receiving, by the processor, selection of the one or more colors for identifying at least one of erasable and retainable contents on the writing board through the user interface;
• and
• transmitting, by the processor, a control signal to a motion control system wherein the motion control system upon receipt of the control signal, controls a retractable erasing surface of the electronic eraser to perform at least one of pushing the retractable erasing surface forward and pulling the retractable erasing surface backward.

A non-transitory storage readable medium including instructions stored thereon that when processed by at least one processor cause an electronic eraser to perform operations comprising:

• receiving an activation signal from a motion detector when the movement of the electronic eraser from the resting position is detected by the motion detector;
• receiving a signal from a proximity sensor when the electronic eraser is proximal to the writing board;
• receiving selection of one or more colors of a plurality of colors displayed on a user interface of the electronic eraser for identifying at least one of erasable and retainable contents on the writing board;
• and
• transmitting a control signal to a motion control system wherein the motion control system upon receipt of the control signal, controls retractable erasing surface of the electronic eraser to perform at least one of pushing the retractable erasing surface forward and pulling the retractable erasing surface backward.
