Those skilled in the art can obtain the gazing point at least by referring to patent document CN105812777B, and details thereof are not repeated herein.
An afterglow area acquisition step: determining the afterglow area of the AR glasses wearer according to the fixation point of the AR glasses wearer; in a preferred example, an area outside a set distance from the gaze point is used as the afterglow area; alternatively, the visual area of the AR glasses wearer is divided into a grid, and a grid area which is not adjacent to the grid where the gaze point of the AR glasses wearer is located is used as the surplus light area. The grids are arranged in rows and columns. Further preferably, the gridding may be a grid dividing the field of view area of each glasses into 5 rows and 6 columns, respectively.
A preference obtaining step: the method comprises the steps of identifying a real object in a real environment in a residual light area, taking the identified real object with the frequency exceeding a frequency threshold value as the preference of an AR glasses wearer, and providing recommendation information to the AR glasses wearer according to the preference. The afterglow area is also an interested area of the user, for example, the user always keeps the pet dog in the afterglow area to continuously pay attention to the behavior of the pet dog. By comparing the common information of the contents in the residual light area under different times, the interested real object in the residual light area can be found.
If a real object continues to appear in the afterglow area for a time greater than a time threshold and is then fixated by the gaze point of the AR glasses wearer, the number of times the real object is recognized is increased by 1 time. The method comprises the steps of storing an image of a real object watched by a gazing point of an AR glasses wearer as a comparison template, and matching the real object to be identified with the comparison template to identify the real object when the real object is identified in a residual light area. For a real object that is a preference of the AR glasses wearer, highlight reality is performed in the afterglow area. For example, the pet dog is watched once, the image of the pet dog is used as a comparison template for storage, and the real object to be recognized in the residual light area is matched with the template to obtain that the real object is the pet dog, so that the recognition rate is greatly increased.
