Pointing

The act of moving a cursor or pointer to indicate a specific location on screen, typically to select, activate, or interact with an interface element. Pointing is a fundamental computer interaction that can be challenging for individuals with motor impairments, tremors, limited range of motion, or reduced fine motor control. Pointing tasks involve target acquisition (moving to the target) and target selection (clicking or activating), both of which can present distinct accessibility barriers. Research on pointing performance following Fitts's Law has informed the design of adaptive interfaces, enlarged targets, and alternative input methods.
