Eye Tracking
Overview
Apple states Eye Tracking is powered by AI, designed for users with physical disabilities, and calibrates in seconds with the front-facing camera. Apple also emphasizes data is kept on device and not shared. Benefit: built-in alternative input for users who cannot rely on touch. Lesson: specialized input should be native, fast to calibrate, and privacy-protective.
Why it matters
Without built-in alternative input, users depend on expensive hardware and fragile integrations. Apple's guidance describes a gaze pointer and dwell-based activation model, which can unlock independence for severe mobility constraints. Call to action: optimize UI for dwell and pointer systems with larger targets, less clutter, and predictable focus flow.
