Prototyping Behavioural Overlays for Adaptive Design

Standard digital interfaces operate on "Zero-Tolerance Logic"—pixels are static, and content is rigid. This creates a hostile environment for the aging population, who face dynamic challenges: Somatic (tremors, motor decline) and Cognitive (anxiety, confusion). This presentation introduces a High-Fidelity Component Library for "Adaptive Materiality", a design system where the interface actively compensates for biological and cognitive decline.

Dual-layer approach to prototyping inclusive experiences:

    1. The Somatic Layer (The Body): Using ESP32 sensors to detect physical capability. We showcase "Smart Components" like the "Magnetic Keypad," which utilizes live accelerometer data to physically stabilize touch targets when hand tremors are detected, and "Heavy Swipes," which add drag resistance to prevent accidental gestures.

    2. The Cognitive Layer (The Mind): Using LLM APIs to mitigate anxiety. We demonstrate the "Jargon Buster," a behavioral overlay that dynamically simplifies complex UI text (e.g., "Authentication Error" $\rightarrow$ "Try Password Again") to reduce cognitive load.

Key Takeaways & Innovations:

This research contributes a production-ready roadmap for the Silver Economy. Attendees will learn how to:

  • Systematize Accessibility: Move beyond static "Senior Modes" by implementing "Behavioral Overlays"—smart micro-interactions that patch accessibility gaps in existing products without requiring a full redesign.
  • Democratize Hardware Logic: Execute a "Sensor-to-Component" workflow in ProtoPie, abstracting complex hardware and API logic into reusable drag-and-drop tools for the wider design team.
  • Bridge Body & Mind: Prove that true inclusivity requires a hybrid approach: Physics to support the hand, and Intelligence to support the mind.
