The advertisement actually shows up in the VR environment, but the effect of this advertisement is obvious, and everyone is interested in this advertisement, these are not known. However, for the advertiser, the more concern is whether the advertisement attracts the user's attention and attracts the user's interest, so we need to find a path to see the actual advertisement display effect and display it according to the advertisement. The effect is to adjust our advertising program.

[0003] At this stage, in the VR advertising space, how to tap the potential interest of users in the mobile scene is a major problem to be solved. In a virtual reality scenario, it is not only limited to the user creating interaction at a fixed point, but the user can move through the entire virtual environment. During the movement process, the user's field of vision changes as the position of the user moves, and the user's attention to the scene changes in different locations. For example, the advertising space that is close at hand is the most attractive to users. After the user's location changes, the user may lose interest in the ad slot due to being occluded by other objects or using a visual blind spot. How to achieve dynamic acquisition The mobile user's interest heat map for the entire scene in the VR advertising space, so as to dynamically adjust the advertising scheme according to the advertising needs, becomes more and more important.
