New system uses low-power Wi-Fi signal to track moving humans — even behind walls
‘Wi-Vi’ is based on a concept similar to radar and sonar imaging.
Seeing through walls
Researchers at MIT’s Lincoln Lab have developed new radar technology that provides real-time video of what’s going on behind solid walls.
Constant connection
MIT researchers show how to use portable devices’ built-in motion sensors to improve data rates on wireless networks.
More precise food-allergy diagnoses
It turns out that many people mistakenly think they have food allergies. A new technology aims to erase all doubt.
Gesture-based computing on the cheap
With a single piece of inexpensive hardware — a multicolored glove — MIT researchers are making Minority Report-style interfaces more accessible.
