Abstract: A method is provided for a television to assist a viewer in improving watching experience in a room in which the television is placed. The television includes a camera unit to capture a room image that contains an indoor environment of the room, and a processing unit. The processing unit finds a visually-interfering condition in the room based on the room image, where the visually-interfering condition is related to a visual interference that would interfere with television-watching. The processing unit then causes a display unit to display the room image, with an overlay that visually signifies the visually-interfering condition covering the room image.

Abstract: A method is provided for advising placement for a speaker set in a room. A computerized device stores rules of speaker arrangement, acquires interior information of the room based on images of an interior of the room, and determines a seating location and a reference location in the room based on the interior information, so as to generate a speaker placement recommendation with respect to the placement of the speaker set in the room. A wearable display obtains the speaker placement recommendation from the computerized device and displays the speaker placement recommendation in augmented reality or virtual reality.
