Project Soli

Project Soli is an experimental project by Google that aims to develop a new type of interaction sensor using radar technology. The sensor can track sub-millimeter motions at high speed and accuracy. It fits on a chip the size of a postage stamp and consumes very little power.

Soli was first announced in 2015, and it has been used in a few Google products, including the Pixel 4 phone and the Nest Hub smart display. In the Pixel 4, Soli is used for Motion Sense, which allows users to skip songs, snooze alarms, and silence phone calls without touching the phone. In the Nest Hub, Soli is used to detect when someone is nearby and to adjust the display’s brightness and volume accordingly.

Google has said that it plans to continue developing Project Soli and to explore new ways to use it in future products. Some potential applications for Soli include:

  • Controlling devices with hand gestures
  • Detecting and tracking people and objects in a room
  • Providing feedback to users about their surroundings
  • Improving the security and privacy of devices

Soli is still in its early stages of development, but it has the potential to revolutionize the way we interact with technology. By using radar to track our movements, Soli could make devices more intuitive and natural to use. It could also help to make devices more accessible to people with disabilities.

Here are some of the benefits of Project Soli:

  • Touchless interaction: Soli allows users to interact with devices without touching them, which can be helpful for people with disabilities or for situations where it is not safe or sanitary to touch a device, such as during a pandemic.
  • Privacy: Soli does not use cameras, so it does not collect any visual information about users. This makes it a more privacy-friendly way to interact with devices.
  • Low power consumption: Soli is very power-efficient, which means that it can be used in devices that need to run for a long time on a single battery charge.

Overall, Project Soli is a promising new technology that has the potential to make devices more intuitive, accessible, and privacy-friendly. Google is still working on developing Soli, but it is clear that this technology has the potential to revolutionize the way we interact with technology.
