OVERVIEW
Touch screen systems have many advantages, including simplification of the user’s task and elimination of a separate keyboard. However, touch screen systems present an insurmountable barrier to many people with disabilities.
THE INVENTION
UW–Madison researchers have developed a touch screen system that attaches a simple button fixture over a portion of the screen. This is important because virtual ‘buttons’ may be difficult to see or manipulate.
The buttons have clear markings that can be felt by a user. When pressed, the buttons contact the touch screen and the task is performed as usual. The button panel may be mounted permanently or fastened. Read the full story here.
