Very briefly, Archea (1984) posits that, in bounded settings, the location of edges (e.g., corners) and surfaces (e.g., walls), their spatial arrangement, and their properties (e.g., opacity) affect the distribution of visual information about the behavior of setting users. A person’s (P’s) position in a setting determines what visual information comes to P about others’ (O’s) behavior (visual access) and comes to O about P’s behavior (visual exposure). This information creates psychological opportunities for P (e.g., for privacy, social interaction, creating a desired impression). P’s capacity to understand, create, and use social opportunities depends upon having the requisite mental and physical competencies.
