• A comparison of area pointing and goal crossing for people with and without motor impairments

  Jacob O. Wobbrock, Krzysztof Z. Gajos (2007) — Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '07)

  Wobbrock and Gajos at the University of Washington present a controlled study comparing two fundamentally different target-acquisition paradigms — conventional area pointing (move into a confined region and click) and goal crossing (sweep the cursor …

• Goal Crossing with Mice and Trackballs for People with Motor Impairments: Performance, Submovements, and Design Directions

  Jacob O. Wobbrock, Krzysztof Z. Gajos (2008) — ASSETS '08: Proceedings of the 10th International ACM SIGACCESS Conference on Computers and Accessibility

  This study investigates whether goal crossing—an input technique where users move through a target boundary rather than clicking within it—can benefit people with motor impairments. The research compares crossing performance against traditional area …
