Shot history page with a recorded shot, favourites filter, sorting and progress stats. — Shot history with favourites, sorting and progress stats.

Detailed feedback listing strengths and improvements, each with the measured angle and a target range. — Detailed feedback on a shot that needs work: what went well, then specific fixes with the measured angle and the target range.

Fig. 5 What the app looks at. MediaPipe Pose gives the joint positions, and the app turns them into angles and checks each one against a target range.

The problem

Beginners rarely have a coach watching, so they often don’t know what’s wrong with their shot. Our user research confirmed that.

How it works

The player records a shot with the camera. MediaPipe Pose tracks the body, and the app checks the shooting elbow, knee bend, shoulder alignment, release extension and posture against target ranges. Then it explains what went well and what to fix, with voice guidance and visual feedback.

A history page keeps past shots, with favourites, sorting and progress stats, so players can see whether they’re improving.

Testing

We tested the prototype with users and watched how they handled camera positioning, the feedback, the history and the filters. That led to concrete improvements: hands-free recording, clearer favourites and more consistent feedback.
