Since blind users are insufficiently involved and developers normally not blind, their mental models are different. In order to cope with these problems the authors present a phase model for blind user-centred design process. Correlating blind user-centred methods are proposed: User analysis through telephone interviews and the reconstruction mental models by methods like teaching back and thinking aloud (Sasse 1991).enmensch und computer 2013 - workshopband
