Abstract: This paper investigates interactive projection jewelry using holographic UIs, emphasizing computer vision algorithms and sensor fusion.
Gesture Control Systems:
Time-of-flight (ToF) sensors and infrared cameras track finger movements with <2ms latency. A convolutional neural network (CNN) trained on 10,000 gesture samples achieves 98.7% recognition accuracy for controls like "swipe to cycle animations" or "pinch to zoom."
Context-Aware Projection:
Environmental sensors adjust projection brightness based on ambient light (lux values). Accelerometers detect orientation changes, enabling dynamic content adaptation—e.g., a rotating necklace displays different zodiac signs when tilted.
Security Features:
Biometric authentication via vein pattern recognition in wrist-worn projectors ensures data privacy. Encrypted Bluetooth 5.3 links prevent unauthorized content uploads.
Case Study:
The "Aura Ring" uses bone conduction speakers and holographic overlays to display caller IDs as floating 3D icons, demonstrating synergy between projection and haptic feedback.
