Visually impaired persons have significant problems in their everydaymovement. Therefore, some of our previous work involves computer vision indeveloping assistance systems for guiding the visually impaired in criticalsituations. Some of those situations includes crosswalks on road crossings andstairs in indoor and outdoor environment. This paper presents an evaluationframework for computer vision-based guiding of the visually impaired persons insuch critical situations. Presented framework includes the interface forlabeling and storing referent human decisions for guiding directions andcompares them to computer vision-based decisions. Since strict evaluationmethodology in this research field is not clearly defined and due to thespecifics of the transfer of information to visually impaired persons,evaluation criterion for specific simplified guiding instructions is proposed.
