Dwell Selection

An interaction technique where a user activates or selects an on-screen element by keeping a cursor, gaze point, or pointer within the target area for a specified duration (the dwell time), rather than clicking or tapping. Dwell selection is essential for people with motor impairments who use alternative pointing methods such as head tracking or eye gaze, where performing a discrete click action may be difficult or impossible. Typical dwell times range from 0.5 to 1.5 seconds, often with visual feedback such as a filling circle to indicate progress toward activation. While dwell selection enables hands-free interaction, it can be slower than direct clicking and may cause unintended selections when users pause to rest.
