Finger radar invented by Google



    The Google ATAP Advanced Technology and Products Division at the I / O conference showed a lot of interesting things. Perhaps the most unusual of the technologies shown is called Project Soli .

    In short, Project Soli is a miniature chip radar that can be embedded in any surrounding objects: mirror, stove, TV. All items that interact with a person. Now they will recognize finger gestures with an accuracy of less than 1 mm, as in the films "Minority Report" or " She ."

    Installation of bulky cameras and additional equipment is not required, especially since no cameras will be able to track movements with a frequency of 10,000 fps, as Soli does.

    Everything is extremely compact. Such gesture recognition can be embedded, for example, in a column.



    Or in a watch.



    This makes sense because the most compact devices have controls that are too small to be in direct contact with them.

    From the stage, Google I / O showed an early prototype of Soli technology, but even it impresses. The recognition accuracy of micromotion of fingers is extremely high, the radar determines the smallest nuances of finger contact and the speed of their movement, for example, if you rub one finger on the other.

    It's nice that the inventor of the radar and the founder of the Soli project is engineer Ivan Pupyrev. In this video, he and his colleagues talk about their development in more detail.



    Work on the project takes only 10 months, but during this time it was possible to reduce the radar to such a size as to make the Soli microcircuit the size of no more than a nail. Small wearable electronics is becoming more popular, so the appearance of such an interface is very helpful.

    In addition, the technology can be useful in virtual reality devices so that the user can realistically contact with objects in the virtual world without wearing gloves.

    Google does not say anything about the timing of the project or any plans to promote it, and where it intends to embed such chips. So far too early, this is just the first demonstration.
