Hands of visually handicapped are eyes for them.
They are recognized objects, living things and space by hand touching.
But, drawing by pencil on paper, it is to easy and common activity to unhandicapped, but it is so hard to visually handicapped.
Art activity is necessary and important to children who are blind or week-sighted.
They cannot appreciate, however, there interest and feeling are not different other common children.
Thus, I suggest these products which are design for tactual sense training for congenital and acquired blind children and application for sensitive instruments for trained blinds.
