Gaze position detection apparatus and gaze position detection method
First Claim
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.

Abstract
A gaze position detection apparatus includes: a memory which stores 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 registered move patterns; a move pattern detection unit which detects 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; a similar-pattern extraction unit which extracts the registered move pattern similar to the move pattern of the user'"'"'s gaze position from among the plurality of registered move patterns; and a correction unit which corrects the gaze position included in the move pattern of the user'"'"'s gaze position using the correction information of the gaze position for the similar registered move pattern.

8. A gaze position detection method including:
-
detecting 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; extracting 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; extracting the registered move pattern similar to the move pattern from among the plurality of registered move patterns of a gaze position stored in a storage unit; and correcting the gaze position included in the move pattern using correction information of the gaze position corresponding to the similar registered move pattern;
whereinextraction of the registered move pattern includes selecting, 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 extracting the similar registered move pattern among from the selected registered move patterns. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer-readable recording medium having recorded thereon a computer program for detecting a gaze position that causes a computer to execute a process comprising:
-
detecting 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; extracting 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; extracting the registered move pattern similar to the move pattern from among the plurality of registered move patterns of a gaze position stored in a storage unit; and correcting the gaze position included in the move pattern using correction information of the gaze position corresponding to the similar registered move pattern;
whereinextraction of the registered move pattern includes selecting, 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 extracting the similar registered move pattern among from the selected registered move patterns.
