Closed-Loop Adaptation

A system design approach where real-time feedback from sensors or user behavior is continuously monitored and used to automatically adjust the system's response. In accessibility technology, closed-loop adaptation enables interfaces to respond dynamically to users' physiological states (stress, fatigue), attention patterns, or performance levels. For example, an interview training system might detect elevated stress through heart rate and adjust question difficulty, or a learning platform might slow down when eye tracking indicates confusion.
