Abstract

Modern software systems struggle to integrate human intent, AI reasoning, and deterministic computation within a unified and auditable framework. While large language models (LLMs) enable powerful semantic interpretation, they lack a structured representation of situational context that can interoperate with traditional systems.

This paper introduces Pulse-Based Situational Reality, where a Signal—an Intention paired with a set of Pulses—represents a complete, identifiable state of contextual relevance. This model forms the foundation of Perceptive Applications, in which human, AI, and system components operate symmetrically as Design Nodes over explicitly represented situational states.

1. Introduction

Traditional systems operate on:

• data structures
• control flow
• hidden state transitions

AI systems operate on:

• natural language
• inference over unstructured context

Human interaction operates through:

• perception
• interpretation
• intention

There is no unified representation across these domains.

This paper introduces:

Situational Reality as the unit of computation.

2. Situational Reality

2.1 Definition

A Situational Reality is defined as:

Situation = (Intention, {Pulse_i})
Pulse = (phrase, trivalence ∈ {Y, N, UN})

Situational reality is defined by what is known, unknown, or fixed, not by data values.

2.2 Identity of Situation

Two situations are identical if:

• Their intention matches
• Their pulse sets (name + trivalence) match

This enables:

• deterministic matching
• traceable execution
• replayable state

3. From State to Reality

Traditional systems:

State = stored data

Perceptive systems:

State = perceived relevance

Example:

Intention: "order.checkout"

Pulses:
- items selected: Y
- payment entered: Y
- address missing: Y

This represents a complete situation:

Checkout is attempted, but address is missing.

4. Design Nodes as Reality Transformers

A Design Node (DN) operates as:

Signal (Situation) → DN → Signal (New Situation)

• Input Signal = current reality
• Output Signal = transformed reality

Computation happens only inside DN.

5. Perceptive Applications

Perceptive Applications are systems where:

• State = Signals (Intentions + Pulses)
• Interaction = Signal exchange
• Computation = DN transformations
• Flow = CPUX

This enables:

• full visibility of application state
• traceable causality
• AI-native integration

6. Dual Role of Human and AI

Human as End-User DN

• perceives situation
• acts through Signals
• validates outcomes

AI role:

situational assistant

Human as Designer DN

• defines Pulses
• builds CPUX flows
• validates logic

AI role:

structural collaborator

Structural Invariance

Signal → DN → Signal

This remains constant across roles.

7. Dual-role Human–AI–System Interaction Model

AI DN (propose) → Human DN (commit) → System DN (execute)

AI proposes, Human commits, System executes.

8. CPUX as Situational Flow

S1 → DN1 → S2 → DN2 → S3 ...

Each step transforms reality.

9. Positioning with Emerging AI Development Approaches

Modern approaches introduce:

• implicit agent reasoning
• hidden state
• reliance on memory and checkpoints

Perceptive Applications:

• make state explicit
• expose transitions
• reduce reconstruction effort

10. Conclusion

Computation becomes:

Transformation of situational realities.

Final Principle

Computation is the transformation of perceived reality through intention.
