Court glossary

Birdzo
The AI coaching persona inside IsoCourt. Birdzo turns stroke scores and pose cues into short tips you can take back on court.
Clear
A high, deep shot usually hit from the rear court to push an opponent back. IsoCourt labels clears among other stroke types when the model sees them.
Contact point
Where racket meets shuttle relative to your body. Contact too far behind often shows up as a weak clear or mistimed smash in the timeline.
Drop shot
A soft shot that lands early in the opponent's forecourt. Often paired with clears from the same setup to disguise intent.
IsoCourt
The product: a web app for badminton clip analysis and live camera coaching. Birdzo is the coach voice inside it.
Live session
Browser mode that uses your camera for real-time feedback while you train, instead of uploading a file first.
Pose tracing
Skeleton overlay on analysis frames so you can see body position at contact and during footwork, not just the shuttle path.
Quality score
A 0–10 style rating of how clean the execution looked for a window or clip summary. It is model judgment, not a tournament ranking.
Smash
A steep, attacking overhead. Analysis looks at timing, contact, and related cues when labeling smash windows.
Split-step
The small hop or load before you move to the shuttle. A late split-step is a common miss pose tracing makes obvious.
Stroke read
IsoCourt's label for what you hit (and related tags like technique or court position) on a timeline window.
