ABSTRACT
Prior work has shown that goal crossing may be a more accessible interaction technique than conventional pointing-and-clicking for motor-impaired users. Although goal crossing with pen-based input devices has been studied, pen-based designs have limited applicability on the desktop because the pen can "fly in," cross, and "fly out," whereas a persistent mouse cursor cannot. We therefore explore possible designs for accessible mouse-based goal crossing widgets that avoid triggering unwanted goals by using secondary goals, gestures, and corners and edges. We identify four design principles for accessible desktop goal crossing widgets: ease of use for motor-impaired users, safety from false selections, efficiency, and scalability.

Foundations for designing and evaluating user interfaces based on the crossing paradigm
Traditional graphical user interfaces have been designed with the desktop mouse in mind, a device well characterized by Fitts' law. Yet in recent years, hand-held devices and tablet personal computers using a pen (or fingers) as the primary mean of ...
Goal Crossing with Mice and Trackballs for People with Motor Impairments: Performance, Submovements, and Design Directions
Prior research shows that people with motor impairments face considerable challenges when using conventional mice and trackballs. One challenge is positioning the mouse cursor within confined target areas; another is executing a precise click without ...
Comparing Touchscreen and Mouse Input Performance by People With and Without Upper Body Motor Impairments
CHI '17: Proceedings of the 2017 CHI Conference on Human Factors in Computing SystemsControlled studies of touchscreen input performance for users with upper body motor impairments remain relatively sparse. To address this gap, we present a controlled lab study of mouse vs. touchscreen performance with 32 participants (16 with upper ...
