OSI Layer 8 — The Human Layer

Layer 8 Human / Emotional

The human emotion layer that operates above the application layer. Eight tracker modules capture mouse kinematics (velocity, acceleration, jerk), scroll patterns, click dynamics, proximity to interactive elements, tab behavior, and form interaction. An inference engine transforms these signals into a 22-emotion taxonomy and delivers an 8-dimension packet to the LLM — so it responds with context instead of guessing.

Protocol: EITP v1.1 (Emotional Intelligence Transfer Protocol) · Cursor physics (v, a, j) · Rage click detection · Proximity hysteresis · Exit intent vectors · 22-emotion classification

Layer 7 Application

HTTP, HTTPS, WebSocket, SMTP, FTP, DNS. Your entire SaaS stack lives here. Everything you build lives at Layer 7.

Examples: Web browsers, REST APIs, GraphQL, email clients

Layer 5-6 Session & Presentation

Connection management, data formatting (JSON, XML, protobuf), encryption (TLS/SSL), compression.

Examples: TLS/SSL, session tokens, JWT, data serialization

Layer 4 Transport

TCP/UDP. Error correction, flow control, reliable delivery. Ensures data gets from point A to point B intact.

Examples: TCP (reliable), UDP (fast), port numbers (80, 443, 3000)

Layer 3 Network

IP addresses, routing, packet forwarding. How data finds its way across the internet.

Examples: IPv4, IPv6, routers, subnets, CIDR notation

Layer 1-2 Physical & Data Link

Cables, switches, MAC addresses, Wi-Fi. The literal wires and network interfaces that move bits.

Examples: Ethernet cables, Wi-Fi routers, network cards, switches

Layer 8 is Infrastructure

EITP v1.1 is a published protocol specification — signal capture, transport, inference, and an 8-dimension packet format. Production-proven across automotive, RV, and powersports verticals.
Not a chat widget. Not analytics. Infrastructure for reading humans.
