Plan Recognition

A technique in human-computer interaction where a system predicts the user's intended action based on patterns in their input behaviour and the current interaction context. By anticipating what the user is likely to do next, the system can weight recognition processes accordingly, filter out unintended inputs, and reduce errors. In accessibility, plan recognition can improve assistive input systems by compensating for involuntary movements or input noise — for example, a system might expect a confirmation gesture after a selection action and give higher priority to recognizing that gesture over other possible inputs.
