HF/OS
Intelligence through governance, not just compute.
Human Factors Operating System
Human-centric interface layer for constitutional AI. HF/OS mediates all human-agent interactions, ensuring ergonomic, cognitively appropriate, and ethically bounded interfaces that honor human authority and autonomy.
Purpose
Human Factors Integration
HF/OS ensures that all AI-human interactions respect human cognitive capacity, cultural context, and individual autonomy. It serves as the primary human-facing layer of ETHRAEON, translating complex system states into clear, actionable interfaces.
- Cognitive load management ensures information presentation matches human processing capacity
- Interaction design patterns prevent manipulation, dark patterns, and cognitive exploitation
- Accessibility compliance guarantees inclusive interface design for all users
Architecture
SIGMA Integration
HF/OS is built on SIGMA (Semantic Interaction and Gesture Modulation Architecture), which provides sensory mapping, feedback loops, and real-time adaptation to user state and context.
- Sensory mapping translates system information into perceptual tokens humans can understand
- Feedback loops ensure users always know the state of the system and pending actions
- Adaptive rendering adjusts complexity and presentation based on user expertise and context
Authority Boundary
What HF/OS Cannot Do
Make decisions for humans, hide information from users, employ dark patterns or manipulative design, proceed without explicit user consent, bypass user input validation, operate without audit trails, restrict user choice or autonomy.
Capabilities
- Adaptive UI: Real-time adjustment of interface complexity, information density, and interaction modality
- Cognitive Load Balancing: Pacing information delivery to match human processing capacity
- Accessibility Compliance: designed to align with WCAG 2.1 AAA guidance for color contrast, keyboard navigation, screen reader support
- Emotion-Aware Interfaces: Detecting and responding to user frustration, confusion, or cognitive overload
- Transparent State Visualization: Clear representation of system state, pending actions, and decision rationale
Evidence & Metrics
HF/OS maintains complete audit trails and metrics for continuous improvement:
- Interaction logs tracking user behaviors, decision paths, and satisfaction signals
- Accessibility audits validating compliance and identifying barriers
- Cognitive load metrics monitoring user stress and comprehension levels
- A/B testing frameworks for interface optimization
Governance
- Human Authority is Absolute: All final decisions rest with informed humans, never automated
- No Dark Patterns: Strict prohibition on manipulative, deceptive, or exploitative design
- Transparency Required: All interface behavior must be auditable and explainable
- Consent Validation: Users must understand what they're consenting to before any action
- Continuous Accountability: Regular review of interface decisions and their human impact
