Motion sensor for smart glasses learns how people move

TDK Corporation announces a new custom sensing solution for intelligent eyewear: InvenSense SmartMotion for Smart Glasses, which enables precise, responsive, context-aware motion tracking for smart glasses, at ultra-low power. Ideal for augmented reality and seamless AI accessibility, this solution enables high-accuracy head tracking, stable image/video capture, intuitive UI control, and posture recognition.

The custom ICM-45685 sensor has on-chip sensor fusion software and optimized memory to support multiple algorithms running on-chip concurrently. This enables simultaneous use of features including precise head orientation tracking, optical/electronic image stabilization, activity/inactivity tracking, and more. Built on the success of ICM-45686, which has been widely adopted for AR/VR, the new ICM-45685 adds software features that target smart glasses applications. ICM-45685 is now available by direct sales inquiry, with additional features like donning/doffing and voice vibration detection (VVD) becoming available at the end of the year.

In addition to the new custom SmartMotion for Smart Glasses ICM-45685, TDK offers a diverse set of sensing solutions for smart glasses and AR glasses, including: PositionSense 9-axis solution (IMU+TMR) for absolute orientation detection and navigation; TMR sensors for glasses hinges (in-use or closed); Low-power MEMS microphones for voice-activated AI and human-machine interface; Ultrasonic time-of-flight sensors for precise wear detection and gesture tracking; Temperature sensors for measuring body temperature or ambient temperature; Temperature sensors for overtemperature monitoring of optical components (e.g. lasers).

TDK sensing solutions for AR/VR and AI glasses applications include the SmartMotion ICM 45685, SmartSoundTM MEMS microphones T5837, T5838, and T5848, plus TDK SmartSonicTM ultrasonic time-of-flight sensors ICU-30201 and ICU-20201. The new SmartMotion for smart glasses, ICM-45685, is available via direct sales inquiry only at invensense.tdk.com/smartmotion or via inv.sa…@tdk.com.
