FRAMEWORK Active

Expert Vision Framework

A proprietary research framework combining AI, behavioral analytics, and cognitive science to model and accelerate expert performance across domains.

Expert Vision is the foundational research program behind my work at the intersection of technology and human performance. It asks a simple question with complex implications: what do experts see that novices miss, and can we model it well enough to teach?

Simple to say. Hard to answer without getting lost in metaphor or hand-wavy “intuition.”

The core hypothesis

Expertise is not only knowledge. It is perception plus procedure — where you look, in what order, what you ignore, what you anchor on, how you recover when the picture changes. If that choreography is observable, it is modelable. If it is modelable, it is trainable.

That is the bet Expert Vision makes.

How Eye-Tracking Works

Expert Vision depends on measurable perception. These diagrams explain the optics and signal path — from pupil and corneal reflection to gaze coordinates on screen.

01

Remote Eye-Tracking Setup

An infrared camera below the screen illuminates the eye and records pupil position relative to the display.

  • Gaze vector (screen → eye)
  • Infrared illumination (camera → eye)
  • Pupil & glint capture

Pupil Center & Corneal Reflection

PCCR — the bright glint on the cornea and the dark pupil center define the optical vector used to estimate gaze angle.

Pupil center
Dark region enlarged under IR — algorithm finds geometric center.
Corneal reflection
Small bright glint from IR LEDs reflecting off the cornea.
PCCR vector
Offset between glint and pupil center maps to gaze direction.

From Eye to Screen Coordinates

Calibration translates the optical vector into X/Y gaze coordinates on the stimulus.

Systems like Eyegaze and Interactive Minds run this pipeline at study scale — calibration, recording, analysis.

Fixations & Saccades

Vision is not continuous motion — it is holds and jumps. Expert Vision models both.

Longer fixations on structural anchors (nav, headers, red accents) — rapid saccades between them. That pattern is what Expert Vision extracts and teaches.

Dwell time accumulates into heat — sharp red accents and structural regions glow first in expert scan data.

How the framework works

We integrate multiple signal streams rather than trusting any single measure. Eye-tracking reveals visual foraging — powered in my research by Eyegaze systems and design practices I learned working there, and Interactive Minds hardware and NYAN analysis software for rigorous study design.

The visual reference above walks through remote eye-tracking, pupil center corneal reflection (PCCR), fixations, saccades, and heatmaps — the measurement chain behind Expert Vision.

Behavioral analytics capture choices under time pressure. Bio-monitoring adds physiological context when tasks are high-stakes. Performance outcomes ground the story in results, not vibes.

Statistical modeling looks for patterns that transfer — not “this expert on this dashboard,” but decision sequences that show up in documentation review, incident response, clinical workflows, competitive gaming, and complex engineering tasks.

Then — and this part matters — we translate findings into systems. Training interfaces. Agent retrieval strategies. UI hierarchies. Organizational playbooks. Research that stops at a paper is incomplete in my book.

Why organizations care

Expertise does not scale by cloning your best person. It scales by extracting patterns without flattening nuance. Expert Vision is my attempt to do that ethically and practically — augment experts, accelerate novices, and design AI that respects how humans actually think.

What keeps surprising me

The same structural bias appears again and again: experts hunt scaffolding first. Novices dive into detail and drown. Our tools — especially knowledge retrieval systems — often optimize for the novice path because it is easier to implement.

Fixing that is not just UX polish. It is a competitive advantage in any domain where decisions are complex and time is finite.

Where this goes next

I am extending the framework into longitudinal studies — how expertise develops when AI tools are present from day one, not bolted on later. Does collaboration change scan paths for better or worse? Can we design agents that reinforce expert perception instead of replacing it with generic summaries?

I do not have final answers. I have a method, early findings, and a stubborn belief that human potential is trainable when we study the right signals.

That is Expert Vision. Not mysticism. Measurement in service of respect.

Methodology

  • Eyegaze eye-tracking platforms and study design methodology (Eyegaze.com)
  • Interactive Minds EyeFollower hardware and NYAN software for gaze capture and analysis
  • Behavioral analytics and bio-monitoring to capture expert performance signals
  • Statistical modeling to identify transferable patterns across domains
  • Systems engineering to translate findings into practical tools

Applications

Accelerated training programs for complex technical roles
Decision-support interfaces that mirror expert information scanning
AI agent design informed by how experts actually retrieve knowledge
Organizational learning systems that capture and distribute expertise

KEY FINDINGS

  • Experts rely on structural cues (headers, diagrams, relationships) before detail — a pattern most RAG systems ignore.
  • Performance under pressure correlates with pre-trained visual scan paths, not faster raw processing.
  • Transferable expertise patterns exist across domains when abstraction focuses on decision sequences, not surface content.
