2021-01-13: Soli: Millimeter-wave radar for touchless interaction by Jaime Lien
Speaker: Jaime Lien
In this talk, we discuss Soli’s development and productization path, from concept to core R&D to integration into Pixel 4. We highlight the tightly intertwined co-design of core radar technology, algorithms, and interaction design in Soli’s development, driven by requirements for a ubiquitous and scalable human sensing technology. We also discuss some of Soli’s new approaches and innovations in radar systems, signal processing, machine learning, and interaction design in order to enable a new modality for sensory perception.
In the second part of the talk, we cover some of the technical challenges faced in integrating Soli radar into the Pixel 4 smartphone, including chip size and placement, power consumption, and interference. We discuss how our cross-disciplinary approaches to these challenges ultimately enabled Soli to successfully ship in the phone.
Finally, we close with future-looking directions for radar in consumer devices. By capturing the sensitivity and precision of human movements in everyday user interfaces, we believe scalable millimeter-wave radar has the potential to revolutionize the way we interact with technology.
