## What is TraceLab?

TraceLab – Your Pocket Video Motion Lab
A powerful alternative to Tracker – turn any video into a motion analysis lab.

Turn any video on your phone into a powerful motion analysis lab. Whether you’re a student exploring physics, a teacher designing engaging lessons, or a curious enthusiast, TraceLab makes complex motion tracking and data analysis as easy as shooting a video.


II. Core Features

1. From Video to Data in Three Steps

Step 1 – Flexible Video Source  
Shoot experiments directly in the app or import any existing video from your photo library.

Step 2 – Precise Setup
Trim clips to focus on key moments. Set scale and coordinate axes (Cartesian or polar) to transform the video into a real measurement space.

Step 3 – Intelligent Object Tracking 
Manually mark points or use AI‑powered segmentation and tracking to handle single or multiple moving objects, even in complex backgrounds.

2. From Data to Insights at a Glance

Comprehensive Data Panel 
Get real‑time tables of all trajectory points. Add computed variables like velocity and acceleration, or create custom formulas for advanced research.

Powerful Visual Charts  
Automatically turn data into intuitive charts. Use multi‑touch to zoom and pan, and apply curve fitting to uncover the math behind your experiments.

One‑Tap Export & Share 
Seamlessly export high‑resolution charts, data tables, or annotated analysis videos – perfect for reports, lesson plans, or collaboration.


III. Key Use Cases

- Sports Science – Analyze a basketball arc, measure golf club head speed, and optimize athletic performance.
- Physics Teaching – Verify free fall, study pendulum motion, demonstrate momentum conservation – bring lab experiments to life.
- Everyday Discovery – Measure your pet’s speed, analyze roller‑coaster acceleration, or record plant growth.
- Engineering – Evaluate vibration frequencies, test prototype motion, and perform quick preliminary validations.


IV. Why TraceLab?

- Lab‑grade accuracy, consumer‑friendly ease – we pack professional analysis tools into a smooth mobile experience.
- AI‑boosted efficiency – intelligent tracking cuts manual labeling, letting you focus on the science.
- One tool, endless possibilities – from classroom to sports field, home to workshop – your universal key to motion analysis.
