【Abstract】 People naturally gaze at the world in conjunction with other activities such as manipulating objects. Eye movements require little conscious effort and eye gaze contains information about both the current task and the well being of the individual. So eye gaze is a good computer input method and it can provide a convenient and natural addition to user computer dialogues. This paper reviews the means and methods of gaze tracking technology, discusses the features of gaze orientation as a modality in human computer interaction, and describes the perspective of gaze tracking technology in the field of human computer interaction.更多还原
