Abstract
A method involving: designating, based on an instruction received from a user, an area within an illumination field of a projector; using the projector to project a light encoded with coordinate information; receiving a content or a content information from the user; associating, using the processing unit, the designated area within an illumination field of the projector with the content or the content information received from the user; detecting the light encoded with the coordinate information using a mobile device positioned within the illumination field of the projector; determining a position of the mobile device within the illumination field of the projector based on the detected light encoded with the coordinate information; and causing, on condition that the determined position of the mobile device is within the designated area, the mobile device to display the content.
