From All About Circuits: Google ATAP is bringing touchless interfaces to the market using a miniaturized radar chip no bigger than a dime. This is Project Soli.
Soli’s radar sensor is a marvel in many respects. For one thing, it solves a long-lived issue when it comes to gesture-recognition technology. Previous forays into the topic yielded almost-answers such as stereo cameras (which have difficulty understanding the overlap of fingers, e.g.) and capacitive touch sensing(which struggles to interpret motion in a 3D context).
Google ATAP’s answer is radar.
Radar is capable of interpreting objects’ position and motion even through other objects, making it perfect for developing a sensor that can be embedded in different kinds of devices like smartphones... (full article)
LiDAR (Light Detection and Ranging) is one of the most reliable methods for parts sensing in factory automation today. SICK has made this technology affordable and easy to use! Click on the video link below to learn about the TiM1xx LiDAR sensor and how it provides: - Area scanning LiDAR technology in a standard sensor package - 200-degree field of view and 3 meter sensing range allows for 169 square feet of area scanning - Compact size and light weight enables ease of deployment in "non-standard" type applications, like end-of-arm robotic tooling - Wide area scanning without having to mount a transmitter and receiver makes installation much easier - IO Link for easy configuration
