This is a good example of both Top-Down Visual Processing and Product Design. As Top-Down Visual Process is defined as “goal-biased attentional looking (fixating),” it starts with “short fixations” to get an overview and recognizing a chair, then we notice the face on the chair and fixate our eyes on it. The scan path of the viewer for this chair would be to first get an overview of the object, the chair. Then, the viewer will focus on the area of interest, the face, by repeatedly scanning that area. This “fixation” occurs based on our prior knowledge or experience that enable us to recognize it as a face image even thought it’s not a real face. In this case, we are mainly concerned with the “cognitive goal.”
