The Process

Five steps from webcam
to insight.

Capture

Desktop app connects to your webcam via Electron. Nothing is recorded or saved.

Analyze

4 AI models run in parallel on-device: face, pose, hands, and eye tracking.

Interpret

Heuristics convert raw landmarks into states like "Focused" or "Poor Posture".

Sync

Only lightweight JSON metadata syncs to Supabase every 30 seconds.

Visualize

Manager dashboard updates in real time via Supabase Realtime subscriptions.

What HALO detects

Four AI engines.
One complete picture.

Emotion Detection

face-api.js with Tiny Face Detector classifies 7 basic emotions. Heuristic modifiers detect Focused (eyebrow tension), Stressed (jaw tension), and Tired states.

Posture Analysis

MediaPipe Pose with 33 3D landmarks scores posture 0–100. Head tilt (50%), spine curvature (30%), and shoulder alignment (20%) combine into an actionable score.

Fatigue & Attention

MediaPipe Face Mesh (468 landmarks) tracks blink rate, microsleeps (>500ms closure), yawn detection via mouth aspect ratio, and gaze direction from iris landmarks.

Hand Activity

MediaPipe Hands (21 landmarks per hand) classifies phone use, typing, and gesturing via zone-based and velocity-based logic. Detects phone near-ear position with geometric rules.

Privacy by design

No big brother.
Ever.

Local inference only

Video is processed in memory by the Renderer process and discarded. It is never saved to disk or sent over the network.

Data minimization

Only derived integers and enums are stored — e.g. posture_score: 85. No images, no video clips, no audio.

Row-level security

Employees can only read their own logs. Managers see only their organisation. Cross-org access is impossible at the database level.

Privacy Mode

A privacy_hidden column lets users toggle visibility of specific metrics — emotion, posture — at the database level.
