Abstract: Meta’s vision is to build AI glasses that deliver personal super-intelligence in a sleek, all-day wearable form. Glasses are the ideal platform, enabling AI to see what you see, hear what you hear, and interact with you seamlessly throughout the day. Recent advancements in CMOS image sensor technologies—especially back-side illumination (BSI) and 3D stacking—are driving the next wave of innovation in AI sensors, which are becoming increasingly vital for AI glasses and other wearable devices.
In this talk, we will first discuss how embedded on-sensor intelligence can significantly reduce system-wide power consumption and latency. We will then introduce several novel AI sensor solutions, including digital pixel sensors and 3D-stacked on-sensor and near-sensor compute architectures. Finally, we will present AI workload examples that demonstrate the critical importance of hardware and software co-optimization in enabling the next generation of intelligent wearables.

Bio: Chiao Liu received the Ph.D. degree in electrical engineering from Stanford University, Stanford, CA, USA, in 2002.,Earlier in his career, he was a Senior Scientist at Canesta Inc. (now part of Microsoft), Sunnyvale, CA, USA, where he developed the industry’s first CMOS time-of-flight (ToF) depth sensors. He served as a Technical Fellow at Fairchild Imaging, Milpitas, CA, USA, and later BAE Systems Inc., Milpitas, contributed to a wide range of technology breakthroughs in scientific and medical imaging fields. In 2012, he joined Microsoft, Redmond, WA, USA, as a Principal Architect for the Hololens AR project. Currently, he is the Director of Research at Reality Labs, Meta Platforms Inc., Redmond, WA, USA, leading the Sensors and Systems Research Team.,Dr. Liu was a member of the IEEE International Electron Devices Meeting (IEDM) Technical Committee. He served as a Guest Reviewer for Nature and IEEE Transactions on Electron Devices.
