Design Requirements

This symposium addresses the challenge of translating user data to specifications suitable for interface development. Four methodologies will be presented: Decision requirements tables, ecological interface design, object-view and interaction design and procedural networks. These four methodologies will be contrasted relative to three dimensions: (1) type of data used in analysis, (2) point in the design process at which each methodology focuses its impact and (3) the formalisms each uses for translating psychological data into engineering data suitable for specification development. Our introductory remarks will elaborate on these three dimensions, and present an example design problem. The four session participants then will present their respective methodologies, how each addresses the three dimensions and how each can be used to address the example design problem.

The Web

The use of color is of great significance to the appearance and usability of web interfaces. However, visually impaired people have always been ignored in web interface design in terms of color scheme. Therefore, it is necessary to study their difficulties while browsing web pages and accessing to information. By means of enumerating the color barriers, this paper summarizes the principles of how to use color in the web interface design for visually impaired people. It is expected that the proposed principles would benefit such people who conduct web interface design while being aware of the needs of visually impaired people.

Actuation System

This paper presents an innovative tactile interactive interface graphical display for visually impaired people, information technology (IT) access application. The display consists of matrix of dots. Each dot is an electro rheological fluid micro actuator. The micro-actuator designed based on linear vertical movement principles. The actuator design and development process is presented in this paper. An advanced software tools and embedded system based on voltage matrix manipulation are developed to provide the display near real time control. Prototype size 124x4 dots, on a matrix form, of 2.54mm pitch, was manufactured. The experimental tests carried out into the prototype showed that each actuator of the matrix was able to provide a vertical holding force of 100 to 200 mN and vertical movement of 0.7 mm. The stroke and dynamic response tests showed the practicability of the developed micro actuation system, for tactile display IT access applications.
