Implements hand and body gesture recognition via MediaPipe on Jetson Orin GPU.
- MediaPipe Hands (21-point hand landmarks) + Pose (33-point body landmarks)
- Recognizes: wave, point, stop_palm, thumbs_up, come_here, arms_up, arms_spread
- GestureArray publishing at 10–15 fps on Jetson Orin
- Confidence threshold: 0.7 (configurable)
- Range: 2–5 meters optimal
- GPU acceleration via Jetson Tensor RT
- Integrates with voice command router for multimodal interaction
- Temporal smoothing: history-based motion detection (wave, beckon)
