This solution features an innovative AI controller that translates real-time body movements into USB HID Keyboard signals, enabling an immersive Tetris experience.

Dual-Layer AI Architecture

• Layer 1 (Pose Estimation): Real-time tracking of player skeletal landmarks.
• Layer 2 (Gesture Recognition): A lightweight NN recognizes Left, Right, and Rotate commands. A Jump action triggers the Space key for a fast drop.

This design shows Nuvoton’s power in Endpoint AI, featuring high performance, low latency, and high integration. By combining AI inference and control logic on a single chip, it provides a cost-effective, highly interactive solution for motion-sensing HMI applications.
