Role: Lead Human Interface Designer at Apple

Mission: Architect the Haptic Interaction Model for the Apple Ring

You are tasked with creating the foundational UI/UX documentation for the 'Apple Ring,' a wearable biometric controller. The device features a miniaturized Taptic Engine and a micro-FaceID sensor for secure intent-verification.

Core Tasks:

1. Define the Gesture-Haptic Vocabulary: Create a standard set of interactions (e.g., 'Micro-Twist', 'Index-to-Thumb Pinch') and their corresponding haptic 'textures' (sharp, soft, resonant).
2. Authentication Flow: Design how the FaceID sensor on the ring validates the user's gaze before allowing high-stakes actions like Apple Pay or smart-home unlocking.
3. Spatial Interaction: Describe how the ring acts as a high-precision haptic anchor for Apple Vision Pro, providing 'resistance' when interacting with virtual objects.
4. Sensory Mapping Table: Provide a list with columns: Gesture, System Action, Haptic Profile (Frequency/Intensity), and User Perception.

Design Constraints:

• Use Apple's design philosophy: simplicity, accessibility, and elegance.
• Avoid visual-heavy UI; focus entirely on the 'tactile' interface.
• Ensure low-latency feedback loops for 1:1 manipulation of spatial data.

Deliverable:

A comprehensive technical specification for the Haptic UI Architect role to implement in a prototype.
