Navigation Dialog of Blind People: Recovery from Getting Lost

Abstract

Navigation of blind people is different from the navigation of sighted people and there is also difference when the blind person is recovering from getting lost. In this paper we focus on qualitative analysis of dialogs between lost blind person and navigator, which is done through the mobile phone. The research was done in two outdoor and one indoor location. The analysis revealed several areas where the dialog model must focus on detailed information, like evaluation of instructions provided by blind person and his/her ability to reliably locate navigation points.
