  • Method for displaying gaze point data based on an eye-tracking unit
    Patent number: 10635900
    Abstract: A method of presenting gaze-point data of a subject detected by an eye-tracking unit includes presenting a test scene picture acquired by a camera unit, and displaying shapes on the test scene picture. The shapes represent momentary gaze points of the subject.
    Type: Grant

  • Detection of gaze point assisted by optical reference signal
    Patent number: 9495589
    Abstract: A gaze-point detection system includes at least one infrared (IR) signal source to be placed in a test scene as a reference point, a pair of eye glasses to be worn by a person, and a data processing and storage unit for calculating a gaze point of the person wearing the pair of eye glasses. The pair of eye glasses includes an image sensor, an eye-tracking unit and a camera. The image sensor detects IR signals from the at least one IR signal source and generates an IR signal source tracking signal. The eye-tracking unit determines adapted to determine the gaze direction of the person and generates an eye-tracking signal, and the camera acquires a test scene picture. The data processing and storage unit communicates with the pair of eye glasses and calculates the gaze point relative to the test scene picture.
