The Accessible Goal Crossing Project is funded by the National Science Foundation as an effort to create user interfaces more suited to people with motor impairments by using goal crossing instead of pointing-and-clicking, which is difficult for many people. Although goal crossing has been investigated on pen and tablet computers for use by able-bodied users, it presents substantially different challenges when used on the desktop with cursor control devices by people with motor control problems. We are designing, building, and evaluating new widgets, design patterns, idioms, and metaphors. It is like the work done at Xerox PARC in 1975, only this time, there is no button on the mouse.
