CARRY is a portable AI basketball training system that integrates real-time computer vision, motion tracking, and interactive training control into a unified practice platform. A multi-camera vision system captures player position, shooting form, and ball trajectory during live training sessions. The system continuously analyzes make-and-miss outcomes and shot mechanics to generate structured performance feedback, including shooting accuracy, consistency trends, and movement patterns over time. The companion application functions as a performance dashboard, visualizing shot distribution maps and longitudinal progress metrics, enabling users to identify specific areas for improvement across sessions. An integrated touchscreen interface allows users to select and configure training drills directly on the device. The system also supports real-time multi-user tracking and gesture-based interaction for dynamic training scenarios beyond static shooting drills. By combining vision-based sensing, data-driven analysis, and interactive training control, CARRY enables a continuously adaptive and measurable basketball training environment for solo and group practice.
