This study examines street-walking training sessions by orientation and mobility spe- cialists for people who are visually impaired. We determine the professional methods used by orientation and mobility specialists to support the spatial perception of people who are visually impaired. Based on the above, when we study the street-walking of people who are visually impaired, we argue the important viewpoint that in this case, walking should be considered “a social action.” We videotape street-walking training sessions and describe the ethno-methods of orientation and mobility specialists. Results indicate that when orientation and mobility specialists describe the surrounding envi- ronment, they highlight spatial arrangements with regard to the boundaries of objects in the street.Through touching and hearing, these objects ’intelligibility is achieved by linking the orientation and mobility specialist’s description of the environment and the spatial perception of the person who is visually impaired. These results suggest walking in the street is a social action, which is related to various configurations of common sense. This research is important to advancing studies on the “order of perception.”
