Detecting people using only WiFi
This is an interesting one. WiFi is everywhere; and probably a reasonable person wouldn’t assume they could be tracked (down to estimates of where they are walking, and the overall pose of their body) if there isn’t a camera around. But it turns out that this data actually can be gathered in (an ideal) WiFi set up. That is, the pose of people was determined without a camera; using only WiFi signals. No doubt this field - sensing human activity through non-camera based sensors - will continue to grow.
