Wi-Fi signals are enough to identify people as they walk by

The way Wi-Fi signals between a transmitter and receiver react can identify people walking past on the other side of a wall, providing that has been videoed walking at some other time, according to researchers at the University of California Santa Barbara. “Our proposed approach makes it possible to determine if the person behind the ...

Sensor fusion lets phone identify objects by simply knocking against them

Objects can be identified by knocking a smartphone against them, according to Korean research lab KAIST. No camera is involved. Instead the technique processes data from the phone’s microphone, accelerometer and gyroscope – recorded simultaneously as the phone is tapped on the object. The system was trained on 23 everyday objects – including books, laptop ...
