One of Google's latest experiments may change the way consumers interact with wearable devices.
Using radar technology, the tech giant's advanced technology and projects team built a sensor for tracking gestures under a program called Project Soli. Google announced the project Friday at its I/O conference.
When the tiny sensor is incorporated into a gadget or wearable, different hand gestures will be able to send signals to the device.
The interaction sensor is still in the development stage and is a couple of years away from being available to consumers.
