standard designs are especially frustrating for the disabled, elderly and anyone who has trouble control a mouse. A new design strategy developed at the University of Washington, an interface will allow "smart" to undergo a short test of skills to each person, which will allow then generated using mathematical calculations a version of herself optimized for the skills motor and vision of that person. This system provides for the first time an instantly customizable approach to user interfaces.
"interface technologies are designed on the assumption that it is people who have to adapt to technology. We tried to reverse that concept and make software to adapt to the people, "said project chief scientist, Krzysztof wedges. Dan Weld and Jacob Wobbrock are coauthors of the research.
The tests showed that the system effectively reduced the difference in handling between healthy and disabled users by 62 percent, and disabled users mostly preferred these custom interfaces generated automatically.
This shows that automatically generating personalized interfaces really does work, and that the technology is ready for use.
The system, called Supple, begins with an appraisal, which in principle needs to be done only once, the skills from one person to point, drag and click with the mouse. The display shows a ring of points and as each point is illuminated, the user must click on it quickly. The task is repeated for different point sizes. Other notices asking the participant to click and drag, you select from a list, and click repeatedly on one point. Participants can move the cursor using any type of device. The test takes about 20 minutes for a person without difficulty and 90 minutes for a person with mobility disabilities.
Then, an optimization program calculates how long it would take the person to complete tasks on a computer and a couple of seconds creates the interface that maximizes speed and accuracy when using a particular program.
The researchers tested the system with six people in a good state of his motor skills and 11 with motor difficulties. The resulting interfaces showed definitively that there is no "one size fits all" in regard to user interfaces.
