Manipulation of Human Behavior by Distorted Dynamics Vision

They say that human plans its motion mostly relying on visual information. From this point of view, in this paper the authors attempt to modify transfer characteristics of human operated system by displaying false image of plant whose dynamics is intentionally distorted from the real to enhance performance. Though the proposed method is a kind of human assisting scheme, it doesn't require any physical actuator unlike others and basically only a sensor system and a display device such as LCD monitor are needed. The authors employ simulated inverted pendulum as target plant to be controlled. In previous works, the authors found that there is a relationship between performance of human who is playing inverted pendulum game and his or her gain from eye to extremity at a certain frequency. The dynamics distortion is performed by 2nd order filter which is based on this relationship. The filter is designed to educe potential performance of human thus it is called as "performance educer" in this paper. Experiments are made by human subjects, in which they provide higher performance than usual. Finally, the validity of proposed idea is discussed
