A control apparatus for a head-mounted display that is worn on a head of a user, comprising:

• a display control unit that causes a list in which a plurality of images are arranged to be displayed on the head-mounted display;
• an information accepting unit that accepts information about an eye fixation duration of the user for an image among the plurality of images, the eye fixation duration being measured by a time measurement unit on the basis of a result of detection by a detection unit, the detection unit detecting an eye gaze of the user directed at the image;
• and
• an information management unit that records the image and the information about the eye fixation duration to a storage unit in association with each other, wherein
• the user is one of a plurality of users, and the display control unit causes lists to be simultaneously displayed on respective head-mounted displays that are worn by the plurality of users, and
• the control apparatus further comprising:
• a sharing instruction accepting unit that accepts a sharing instruction from the user;
• and
• a mode switching unit that switches between a shared mode in which an eye fixation target image is indicated for the plurality of users and a non-shared mode in which the eye fixation target image is not shared among the plurality of users, the eye fixation target image being the image in the list at which the eye gaze of the user that has given the sharing instruction, which is an instructing user, is directed.
