Google ATAP’s Project Soli
“Project Soli is using radar to enable new types of touchless interactions – one where the human hand becomes a natural, intuitive interface for our devices. The Soli sensor can track sub-millimeter motions at high speed and accuracy. It fits onto a chip, can be produced at scale, and can be used inside even small wearable devices.” https://youtu.be/0QNiZfSsPc0
Project Soli was started as a means to track the highly articulate motion of the human hand. Soli’s radar technology is sensitive enough to register the most minute gesture of the human hand and small enough to be practical in numerous applications. This technology will not only improve the way we interact with our daily technology (cell phones/computers/appliances/homes?) but will grant new opportunities in the field of gestural input based design. Furthermore, this technology could be implemented in completed designs to create responsive environments. We are approaching a point in technology where the interface will become seamless. We aren’t quite at the level of the holographic STARK computer from the Iron Man film franchise, but Project Soli provides a basis for making that type of interface possible.
