The Vi.S.In blog
Practical guides to measuring how you move. No lab required.
Getting started with Vi.S.In
From dropping in your first video to reading joint angles, presets, and sharing results in a five-minute tour of the analyzer.
An intro to pose detection and biomechanics
How a neural network finds 26 points on a moving body, how joint angles are computed from them, and what that can (and can't) tell you about movement.
Running form by the numbers
Cadence, ground contact time, vertical oscillation, shin angle at footstrike, what each metric means, and how to measure yours from a phone video.
A DIY bike fit with your phone
The five joint angles a bike fitter measures, the ranges to aim for on a road or TT position, and how to check your own fit from a 20-second trainer video.
