    Abstract: A system for gaze direction detection is disclosed herein. The system comprises a face detection unit configured to detect face information from a captured image of a spectator, a head pose unit configured to detect a head pose angle based on the face information; an eye measurement unit configured to detect eye information of at-least one of a left eye or a right eye of the spectator based on the detected face information; an eye-gaze detection unit configured to estimate a gaze angle of the at-least one of the left eye or the right eye of the subject based on the eye information; a conditional gaze detection unit configured to calculate a resultant gaze angle based on the estimated gaze angles of the left eye and right eye and the head pose angle; and an effective gaze detection unit configured to estimate an effective gaze angle based the resultant gaze angle and head-pose angle.

    Abstract: A muscular fatigue determination apparatus includes an information obtaining unit that obtains loads applied to a pedal of a bicycle, rotation speeds of a crank of the bicycle, and myoelectric potentials of a user, the myoelectric potentials and the loads being in a one-to-one relationship, the myoelectric potentials and the rotation speeds being in a one-to-one relationship, and a muscular fatigue information generation unit that generates muscular fatigue information regarding the user on the basis of whether a difference between the myoelectric potentials of the user is larger than a first threshold, each of the myoelectric potentials being associated to a load range that is one of load ranges and to a rotation speed range that is one of rotation speed ranges, each of the loads belonging to one of the load ranges and each of the rotation speed ranges belonging to one of the rotation speed ranges.
