‘Ripple’ open standard: Puts Soli-like radar on more devices

Soli, which has been in development for years, has finally launched with the Pixel 4 and the 2nd-generation Nest Hub. Google is now working on the Ripple open API standard with a number of partners. They to “accelerate the growth of general-purpose consumer radar applications.”

Experts from across the silicon, sensing, automotive, and electronics industries have come together to develop open and standardized API interfaces for radar system development. Standardized API calls for general purpose radar enable interoperability and the rapid deployment of new applications.

According to the company, Ripple enables interoperable software libraries that “work across various radar hardware implementations, ensuring reusability and easier firmware upgrades,”. This comes at a time when the radar is “smaller, cheaper, and lower power” than it has ever been. The open API standard allows for a “lower barrier to entry” that will hopefully lead to “new products and services for consumers.”

Ripple will enable developers to create specialized extensions so that they can build on the standard to support their own differentiated use cases. These extensions can be incorporated as official interfaces in future versions of the standard.

Radar has been useful for speeding up face unlock and quick gestures on the Pixel 4 and 4 XL, and it’s also used for sleep tracking on the Nest Hub. Surprisingly,  Ripple is “hosted by” the Consumer Technology Association (CTA), which promotes the following radar applications — the first three of which Google is already using:

  • Non-invasive wellness monitoring
  • Human activity recognition
  • Touchless gesture controls
  • Occupancy detection

Currently, Google, Ford, Blumio, and Infineon, NXP, and Texas Instruments are among some of the Ripple participants. In addition, all the technical details are now available on Github.
