More about SmartMotion® for Smart Glasses

TDK’s custom-built solution ICM-45685 for smart eyewear and wearables applications, powers real-time, intelligent motion tracking in a compact, low-power form factor. If you’re building AR experiences, fitness-focused wearables, or productivity eyewear, this IMU makes it possible.

Key features of ICM-45685 – SmartMotion for Smart Glasses:

  • Precise head orientation tracking:
    On-chip Gyro-Assisted Fusion (GAF) algorithm for high-accuracy motion tracking
  • Ultra-low power IMU:
    Designed for extended battery life in compact wearable design
  • Embedded ML + Sensor Inference Framework (SIF):
    Run multiple decision trees for activity classification, motion triggers, and more
  • OIS/EIS:
    Optical and electronic image stabilization for built-in cameras
  • Vocal vibration detection (VVD):
    Bone conduction sensing for intuitive speech detection
  • BalancedGyro™ vibration rejection:
    Minimizes false motion triggers for robust tracking in motion-heavy environments
  • Optimized memory architecture:
    Supports concurrent algorithm execution with efficient power and memory use
