the evaluation of visually impaired people's ability of defining the object location on touch-screen
Touch-screen has been used not only on home appliances but also on so many kinds of machines in public facilities at the present time. However the fact is that most of visually impaired people have a problem with the difficult usability of a touch-screen. We come up with an idea of Presentation Methods of Sound Information, which is thought to enable visually impaired people to define the object location on the touch-screen. We also make a proposal of the Concentration game content that is possible in improving the Sound localization's ability and evaluating the visually impaired people's characteristics of touch-screen's operation method. In this paper, we introduce the results of the experiment that we conducted with 5 visually impaired people. These are evaluated through the way of the finger moving on the touch-screen panel while using this content, and the ability of defining the object location.
