Doherty that help designers and evaluators maintain a user-centered approach throughout the design process.
HOW IT WORKS: Immediate visual or system feedback sustains attention, prevents cognitive interruption, and maintains a continuous perception of control during active interaction.
IN UX/UI/AIX DESIGN: AI interfaces must provide instant reactions, micro-feedback, and progressive responses to preserve user flow during prompts and decision-making actions.
EXAMPLE: A conversational AI streams partial results, visual progress, and confirmations while generating responses, preventing waiting anxiety and interaction abandonment.
