Motor ability

The capacity to perform physical movements required for interaction with technology and the environment, encompassing sub-constructs including strength, dexterity, coordination, range of motion, speed, accuracy, endurance, and tremor control. Motor ability is not a fixed trait but emerges from the intersection of the user (their stable motor characteristics), the task (the specific motor demands of the action), and the context (environmental factors like device, posture, and fatigue). Understanding motor ability as dynamic and multidimensional is essential for designing adaptive accessible interfaces.
