Staring is a prolonged gaze or fixed look. In staring, one object or person is the continual focus of visual interest, for an amount of time. Staring can be interpreted as being either hostile like disapproval of another's behavior, or the result of intense concentration, interest or affection. Staring behavior can be considered as a form of aggression like when it is an invasion of an individual's privacy in certain contexts, or as a nonverbal cue to convey feelings of attraction in a social setting. The resultant behavior or action defines whether it is aggressive in nature (e.g. leering that result's in street harassment), passive or active expression of attraction, etc. However, to some extent staring often occurs accidentally, and often it would be simply staring into a space for awareness, or could be lost in thought, stupefied, or be unable to see. As such, the meaning of a person’s staring behavior depends upon the attributions made by the observer.
Optical system for fog display point diffusion and preparation method thereof
The invention relates to the technical field of optical elements, and discloses a fog display point diffusion optical system and a preparation method thereof, and the preparation method comprises the steps: obtaining user visual parameters, and building a visual behavior probability density model through kernel density estimation; designing the front surface of the lens based on the model, and generating an asymmetric defocus system coupled with a gazing habit; the rear surface of the lens is designed, and the distribution density of a fog display point diffusion unit is cooperatively modulated by the front surface defocusing amount, the fixation probability and the pupil diameter; and finally integrating front and rear surface design to form an optical lens body. According to the method, the asymmetric defocus field on the front surface and the fog display point diffusion field on the rear surface are subjected to collaborative design, and the defocus intensity and the contrast modulation intensity are accurately applied to the effective retina area of the user through the visual behavior probability density model; the technical problem that a traditional out-of-focus lens is fixed in signal and cannot adapt to individual staring habits and physiological parameter changes is solved.
