1. A gaze position detection apparatus comprising:

  • a memory configured to store a plurality of registered move patterns of a gaze position and correction information of the gaze position included in the registered move pattern for each of the plurality of registered move patterns; and

    a processor configured to;

    detect a move pattern of a user'"'"'s gaze position, from a plurality of measurement points of the user'"'"'s gaze position which are obtained from data items representing a user'"'"'s gaze direction generated by a gaze detection device in different timing;

    extract at least one feature among a first feature related to the user, a second feature related to an arrangement of the gaze detection device, and a third feature related to the environment at the time when the move pattern is detected;

    extract the registered move pattern similar to the move pattern from among the plurality of registered move patterns; and

    correct the gaze position included in the move pattern using the correction information of the gaze position for the similar registered move pattern, wherein the memory stores the at least one feature among the first feature, the second feature, and the third feature, for each of the plurality of registered move patterns, andthe processor selects, among the plurality of registered move patterns, one or more registered move patterns, a difference between the at least one feature for the move pattern and the at least one feature for the registered move pattern being within a predetermined allowable range, and extracts the similar registered move pattern among from the selected registered move patterns.
