Improved access to computers for the visually handicapped: new prospects and principles

Abstract

Absfruct-This paper discusses the future of computer access products for people with a visual handicap. The existing special computer access solutions are briefly reviewed. Their limitations are examined in terms of a human-computer interaction, and the technical origins of these limitations are analyzed. New technologies are explored and their potential for significantly improving the human-computer interface are reviewed. Finally, principles for the future development of nonvisual human-computer interfaces are proposed.

Automatic visual to tactile translation. I. Human factors, access methods and image manipulation

“…This is also described as the convolution over X by a blurring mask or kernel. For example, the blurring algorithm used in this research is accomplished with the following 3 3 kernel B: (11) Segmentation: Images are generally comprised of one or more regions, de ned as sections or segments of an image whose members are all closely related by color or intensity. Segments are essentially the areas between edges.…”

Hands free interface for Human Computer Interaction

“…[1] However, there is very little attention paid for providing solutions for disabled people to use computers conveniently. [2] To pursuit computers functions properly, the user has to interact with its two most important input devices of a computer [3], which are the keyboard and the mouse which are not designed to aim to be used by disabled people. [4] Thus, this research is aimed to give a comprehensive solution, which could actually be used by a disabled person in comfortable manner.…”
