Tensity Research Based on the Information of Eye Movement
This addresses the need for a suitable tension measurement method in human-robot interaction, but it appears incremental as it builds on existing eye movement indices.
The paper tackled the problem of measuring user tension during human-robot interaction by proposing a method based on eye movement information, and the result was that the method was proven effective through experiments.
User's mental state is concerned gradually, during the interaction course of human robot. As the measurement and identification method of psychological state, tension, has certain practical significance role. At presents there is no suitable method of measuring the tension. Firstly, sum up some availability of eye movement index. And then parameters extraction on eye movement characteristics of normal illumination is studied, including the location of the face, eyes location, access to the pupil diameter, the eye pupil center characteristic parameters. And with the judgment of the tension in eye images, extract exact information of gaze direction. Finally, through the experiment to prove the proposed method is effective.
