The line-of-sight (LOS) detection system has various applications, such as in the field of communication technology, human-computer interaction, safety and security [1]. In early studies, using an external camera and infrared camera to detect the location and motion of the pupil is the mainstream method of detecting LOS. However, these methods involve several problems in that they restrict users' activities and expose them to physical and mental stress. With this in mind, a solution to enhance the practicality of the promising LOS detection applications, with systems that do not impose any restriction on users' activities nor expose them to any stress, is strongly demanded.
