Outline of Final Research Achievements

We developed a software tool to support visually handicapped person for documents in elementary geometry. A sighted support input information elements by using a mouse or a keyboard, and visually handicapped student obtain them as text documents. For adequate use of graphical document, we have to estimate the importance of information elements in the documents. We estimate them by using the positions or movements gaze points. In these analysis we also developed generalized methods. We developed discrimination method using Choquet Integral, and improve linear regressions using a normalization of feature values considering their distributions.
