It summarizes six determinants that affect PA from three dimensions of space, place and perception. Every determinant is categorized by the indictor, content, the type which affects PA. Finally, a primitive framework of GOS PA determinants is established, and based on this, the corresponding design inspiration as well as future research trend are summarized.
