The Overlay Video transforms your recorded task into an interactive visualization of posture and risk. Instead of viewing raw footage alone, this feature layers ergonomic data directly onto the video — helping you see where, when, and how risk occurs.
This article explains what you’ll see and how to use it.
What is the Overlay Video?
The Overlay Video combines:
Your original task footage
A tracked skeletal model
Joint-level risk indicators
Real-time risk scoring
A timeline of exposure
It connects movement data to the real-world task so you can visually understand risk patterns.
What You’ll See on Screen
The Overlay Video is divided into key visual areas.
1. Ergonomic Risk Score (Right of Screen)
On the right side of the screen, you’ll see:
Overall Ergonomic Risk Score
This proprietary score combines:
Posture
Reach
Hand load
Task frequency
Task duration
It provides a single summary measure of total task risk.
Upper- and Lower-Body Sub-Scores
These help you determine whether risk is primarily driven by:
Upper-body demands (shoulders, arms, back)
Lower-body demands (hips, knees, legs)
Live Risk “Thermometer”
While static values summarize the entire task, the live indicator updates in real time as the video plays. This allows you to see:
When risk increases
When posture improves
Which parts of the task are most demanding
2. Timeline View (Bottom of Screen)
At the bottom, you’ll find a timeline that highlights:
Moderate-risk moments
High-risk moments
This makes it easy to:
Jump to key sections of the task
Identify peak exposure periods
Focus improvement efforts on the most critical moments
Instead of watching the entire task repeatedly, you can quickly navigate to the highest-risk events.
3. Joint Risk Gauges (Left of Screen)
On the left side of the screen, you’ll see an avatar with joint indicators at:
Shoulders
Elbows
Knees
Low back
These gauges show how cumulative risk builds over time at each joint.
This provides insight into:
Which joints are most exposed
How exposure accumulates throughout the task
Whether certain body areas are consistently under strain
4. Tracking Skeleton & Hot Zones (On the Worker)
Directly on the worker in the video, you’ll see:
Motion Tracking Skeleton
A digital skeleton overlays the body to show joint tracking and movement patterns.
Yellow Markers
Yellow indicates moderate-risk posture — positions that may increase risk if repeated or sustained.
Red Markers
Red indicates higher-risk posture — positions where injury likelihood may increase more quickly.
Color-Changing Bounding Box
The box surrounding the worker changes color to reflect the highest-risk joint at any given moment. This gives you an instant visual cue about overall posture severity.
How to Use the Overlay Video Effectively
The Overlay Video is especially helpful for:
Identifying peak risk moments
Understanding why a task scored high or low
Demonstrating risk visually to stakeholders
Coaching workers on posture improvements
Supporting ergonomic documentation
You can pause, replay, and navigate through the timeline to examine specific movement phases in detail.
Why the Overlay Video Matters
Numbers alone don’t always tell the full story.
The Overlay Video:
Connects risk scores to real movement
Shows exactly when risk increases
Identifies which joints are most exposed
Provides visual evidence for decision-making
It bridges the gap between data and action.
Summary
The Overlay Video allows you to:
See risk as it happens
Identify moderate and high-risk postures
Track cumulative joint exposure
Navigate directly to peak moments
Translate analysis into actionable insight
It’s a powerful way to evaluate movement and communicate risk clearly.
