An offline performance tracking app built for karate athletes, coaches, and referees. Using computer vision and pose estimation, the app analyzes user-submitted videos to evaluate technique, count strikes, measure speed, and visualize movement paths. Designed with a modern, minimalist UI, the app brings data-driven insights into the world of martial arts — making scoring, training, and performance feedback smarter and more accessible.
WORLD KARATE FEDERATION
2021 - PRESENT
To create a smart, real-time system that uses computer vision to analyze karate movements — helping athletes improve technique, coaches give accurate feedback, and referees evaluate performance with data-driven precision.
Problem Definition & Research
Identified the lack of objective scoring tools in karate and explored how pose estimation and computer vision could fill that gap.
Data Preparation & Model Training
Collected and annotated karate videos to train custom models using ViTPose and YOLO for pose detection and movement tracking.
UX/UI Design
Designed a clean, intuitive interface for users to upload videos, view analytics, and track performance easily.
Prototype Development
Built interactive screens including Welcome, Upload, Guide, and Results pages, simulating real-time feedback and analytics.
Testing & Iteration
Refined detection accuracy, interface usability, and feedback clarity based on early testing with athletes and coaches.
Presenting project and prototype in Virginia, San Diego and New York to Antonio Diaz who member of Athletic Commission of World Karate Federation! This project presented all around the World Karate Federation Commission Members!
This is going to be a gamechanger of combat sports!
The final product is a cutting-edge mobile app that delivers real-time performance analysis through pose estimation and object detection. Users can upload their karate videos and receive instant feedback on speed, technique, accuracy, and movement patterns. The app empowers athletes to improve their skills, coaches to give precise guidance, and judges to evaluate more objectively — bridging the gap between tradition and technology in martial arts.
