Researches at the University of Washington have recently developed a system, which for the first time, offers an instantly customizable approach to user interfaces. Each participant in the program is placed through a brief skills test and then a mathematically-based version of the user interface optimized for his or her vision and motor abilities is generated. The current off-the-shelf designs are especially discouraging for the disabled, the elderly and others who have trouble controlling a mouse, because most computer programs have standardized button sizes, fonts, and layouts, which are designed for normal users.

The next part of the system is an optimization program, which calculates the duration needed for the specific person with special needs to complete the range of computer tasks. Within a few seconds, the system is able to generate the interface that takes full advantage of the person's precision and speed when using a specific program. Lead researcher Krzysztof Gajos says, “Assistive technologies are built on the assumption that it's the people who have to adapt to the technology. We tried to reverse this assumption, and make the software adapt to people.”
The team recently tested the system on six able-bodied people and eleven people with motor impairments. A man with heightened cerebral palsy used his chin to manipulate a trackball and was able to move the pointer rapidly but spastically. Using the results from the man’s test, Supple generated a user interface where all buttons were larger than the usual, and lists were expanded to reduce scrolling. Future considerations include adapting the current system to be applied to screens of various sizes, for instance handheld devices. The only drawback would be that the whole system would need to be completely re-designed specifically for different sized screens. However, initial uses are likely to be for web-based applications. TFOT has previously written about alternative mouse manipulation, where people with disabilities can use the computer with unique software which utilizes a simple camera that tracks the user's eyes across the screen. You can also check out our article about mind controlled bionic limbs which discusses how primates have shown how they can move a robotic arm merely by thinking about it via sensors picking up their brain-signal patterns. TFOT also covered COGAIN - gaming without hands, only the player’s eyes. The new technology brings hope to disabled gaming-lovers who usually cannot enjoy new games that use advanced, three-dimensional graphics. Additional information on Supple specialised user interface can be obtained at the University of Washington website. |
