Utilizing ITRI’s advanced 3D packaging technology, the AI Badminton Trainer creates a cutting-edge solution for precision badminton training. The vertically stacked multi-functional chips shorten die-to-die spacing and increase signal transmission speed. This results in a compact design that eliminates the need to connect several devices. While the high-speed video camera captures the player’s position and movements, the system transfers data such as swing posture and hitting position to a cloud platform. Gen AI is integrated to analyze the player’s skills and offer instant performance assessments and personalized training programs. This innovation has been introduced to a gym center to provide sports training services.
