摘要： 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.

摘要： Provided is an electronic device. The electronic device according to the present disclosure can adjust the length of a band surrounding a user's head, by sensing pressure of a part of the electronic device coming into contact with the user. Furthermore, the electronic device according to the invention can identify a direction in which the user's eyeball looks, and deduce the user's facial expression, by sensing the movement of muscle around the user's eyeball. The electronic device of the invention can be associated with artificial intelligence modules, robots, augmented reality (AR) devices, virtual reality (VR) devices, devices related to 5G service, etc.
