Display method and display system

A display system comprising:

• a first sensor;
• a second sensor;
• an optical device which projects image light;
• a drive device configured to turn a direction in which the image light is projected to a predetermined direction;
• and
• a processor programmed to execute
• obtaining first information for identifying a user, based on output of the first sensor,
• obtaining second information which is related to a position of the user, based on output of the second sensor,
• determining a first direction based on the second information,
• determining an image genre based on a combination of the first information and the second information, and
• projecting the image light representing the image of the image genre toward the first direction by controlling the optical device and the drive device, wherein:
• the second information includes information representing a second direction in which the user is located with respect to the second sensor;
• the determining the first direction includes determining an opposite direction to the second direction as the first direction;
• the second information further includes information representing a room type where the user is to be located, the room type being a kind of room;
• the determining the image genre includes determining the image genre based on a combination of the first information and the room type;
• the second sensor is a first camera configured to take an image in one direction;
• and
• the obtaining the second information includes:
• obtaining a first image including the user based on output of the first camera;
• determining the second direction based on the first image;
• obtaining a second image including an area located in the first direction based on the output of the first camera;
• and
• determining the room type based on the second image.

• the determining the first direction includes determining the first direction based on a combination of the first information and the room type;
• the second sensor is a second camera configured to take an image in a 360-degree direction;
• and
• the obtaining the second information includes:
• obtaining a third image including an area included in a 360-degree range centering on the second camera based on the output of the second camera, and
• determining the room type based on the third image.
