Abstract
Disclosed are a projector device providing augmented reality and a method for controlling the projector device. The projector device includes a body; a projector disposed in the body and configured to project augmented reality information onto a projected region on a predefined object; a camera disposed on the body to be movable relative to the projector, wherein the camera is configured to measure a distance therefrom to the projected region and to sense an input to a sensed region of a predefined size at the measured distance; and a controller configured to control the projector and the camera, wherein the controller is configured to align the sensed region with the projected region, based on a relative position of the sensed region to the projected region, such that the camera receives the input accurately.
