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.
