The places in which people find themselves affect the occupations in which they engage and the value they hold for those occupations within those settings. for people with disabilities, each journey into their communities requires them to engage in a distinctive interaction with the physical spaces they encounter. Each encounter with a building or a feature of a space requires the person to confront an array of challenges that, if not congruent with his or her abilities, may inhibit participation and activity. The built environment-the human-made surroundings that provide the setting for activity-strongly influences the extent to which individuals participate and find meaning. Understanding the significance of the environment, the challenges in creating congruence between people and spaces, and how people interact within the built environment are critical to advancing the participation of persons with disabilities within the public realm.
