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

Slipping and drifting: using older users to uncover pen-based target acquisition difficulties
Moffatt and McGrenere present an empirical study at the University of British Columbia investigating the underlying causes of pen-based target acquisition difficulty on a Tablet PC, with explicit attention to how age affects targeting ability. Thirty…

Accuracy and Frequency Analysis of MultiTouch Interfaces for Individuals with Parkinsonian and Essential Hand Tremor
This 2005 study from the University of Delaware compares four computer pointing devices — an optical mouse, optical trackball, isotonic joystick, and a FingerWorks MultiTouch Surface (MTS) — for users with Parkinsonian tremor and essential tremor. Th…

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

Simulation of Motor Impairment in Head-Controlled Pointer Fitts' Law Task
This poster paper proposes simulating motor impairments in a head-controlled mouse pointer system (Camera Mouse) to address the challenge that participants with motor impairments are not always available for accessibility research or software develop…
