An interesting project which may have applications beyond chemical engineering.

The system also includes >an audio, screen-reading component and audible indicators of certain >software functions. Researchers have also overcome a major obstacle >associated with the user function of dragging and dropping or copying and >pasting. A tablet computer with a customized overlay, a tablet pen >functioning as a computer mouse, and alignment holes mapped to the tactile >objects help facilitate the drag-and-drop function, which is the method >that connects unit operations. > >"We are far enough into this project for me say that we have significantly >minimized the differences between visually impaired and sighted engineers >who do process design," Beitle said. "While we haven't eliminated all >differences, we have reached a point where a blind chemical engineer can >conduct himself as any engineer by manipulating process-engineering >software to achieve improvements or investigate alternatives." > >The system has been extensively tested at a process-engineering firm by >Noel Romey, a graduate student in the Ralph E. Martin Department of >Chemical Engineering. Romey, who has been blind since birth, came to the >university to study chemical engineering. Since May, he has tested the >system by simulating and designing various chemical facilities. The >extensive designs are used by clients of the design firm to improve >manufacturing systems. > >The teaching and practice of chemical-engineering design traditionally has >had a strong visual component due to many visual tools that describe >concepts and processes. This reality, combined with the fact that >industry-specific software does not include any adaptive-technology >features, means that professors and engineering professionals have little >experience with visually impaired students, which may contribute to blind >and visually impaired students avoiding the profession. > >Beitle's team converted GUIs into TUIs. GUI stands for graphical user >interface, which describes software that relies heavily on icons and >visual tools to represent concepts, functions and processes. Of course, >behind any GUI are codes programmed to execute various user commands, such >as opening programs or dragging documents. To accommodate those who can't >rely on visual cues, the researchers had to alter this visually dependent >system into something that could be felt - a tactile user interface. Their >system includes a TabletPC or CintiQ - personal computers/screens that >simulate notepads - and a pen-based mouse. Most importantly, the system >uses custom-made tactiles - small objects embossed with patterns that >represent various GUI icons that symbolize parts, such as valves, pumps >and reactors - and an overlay that is placed on the screen. The tactiles >adhere to the overlay. Alignment holes on the tactiles allow users to >place them at desired locations on the overlay and thus build process-flow >diagrams. Tactile and graphical interfaces are the same size because when >a tactile is clicked, the design is built on the computer screen under it. > >In addition to the computer modifications, the research project has an >equally important psychological component, one that Beitle thinks will >help both sighted and visually impaired engineers. Whether in the >classroom or at an engineering firm, engineers must work as a team on >design projects. This reality made Beitle think about the importance of >language and the verbal exchange of information between blind and sighted >professionals. How can design team members convey technical information >when a visual diagram cannot be relied upon? > >To answer this question, Beitle and his design students collaborated with >Douglas Behrend, professor and chair of the psychology department in the >J. William Fulbright College of Arts and Sciences, and Rachel Schwartz, a >psychology graduate student. Led by Schwartz and Behrend, who is an expert >in cognitive and language development, the researchers studied individuals >with different communication styles and measured the reliance on vague >language, visual cues and gestures. When working with Romey, sighted >students seemed to modify patterns of communication styles in ways that >suggested they were considering the dynamics of working with a visually >impaired colleague. Behrend said this may be explained by group members >using metacognition, which psychologists broadly refer to as individuals' >knowledge of and about their own and others' cognitive processes. > >"This added dimension of this project will prepare sighted members of a >design team to communicate effectively in a technical fashion with less >reliance on visual cues," Beitle said. > ><http://dailyheadlines.uark.edu/11589.htm>http://dailyheadlines.uark.edu/11 589.htm > > >*Contact:* > >Bob Beitle, professor of chemical engineering, Louis Owen Professor of >Green Chemical Process Design and Development, Ralph E.
