Abstract
The present disclosure discloses a method and system for detecting visual attention. Embodiments of the present disclosure collect time sequences and corresponding pupil diameter sequences of each point of regard during visual attention process. Attention change curve is plotted according to the corresponding relationship between time sequences and pupil diameter sequences. The attention change curve is divided into four stages based on pre-setting time parameters and pupil diameter parameters. Numerical analysis of each stage is finished based on duration and rate of pupil change. Quantitative calculation of visual attention of each stage is realized, and the changing procedure of visual attention can be portrayed entirely, systematically and quantitatively.
