WiTrack is a device that tracks the 3D motion of a user from the radio signals reflected off her body. It works even if the person is occluded from the WiTrack device or in a different room.

WiTrack localizes the center of a human body to within 10 to 13 cm in the x and y dimensions (about the size of an adult hand), and 21 cm in the z dimension. It also provides coarse tracking of body parts, identifying the direction of a pointing hand with a median of 11.2 degrees.

Great for gaming, controlling household appliances and elderly monitoring & fall detection.

• The center point of aircraft must stay inside a 10x10 meters square.

For 33 years a lot of people tried to win the prize, and on June 13th 2013 the award was finnaly won by AeroVelo, a team of students and professors from the University of Toronto.
