Direct Manipulation

An interaction style in human-computer interfaces where users directly act on visible objects rather than issuing commands. Key characteristics include continuous representation of objects, physical actions instead of complex syntax, and immediately visible results. Examples include dragging files to folders, resizing windows by pulling edges, and pinch-to-zoom gestures. Direct manipulation interfaces support "recognition over recall" — users can see options rather than memorizing commands. This paradigm is largely unavailable to screen reader users, who must navigate sequentially through content and memorize keyboard shortcuts.
