Wi-Vi: See Through Walls with Wi-Fi Signals





What Can Wi-Vi Do?
Detect the Number of Moving Humans in a Closed Room
Wi-Vi allows us to detect presence of a moving human in a closed room. It can also can determine with high accuracy up to 3 moving objects.
Determine the Relative Locations of Moving Humans

The technology can also determine the motion of different persons in a closed room. It can answer questions such as: Is the person moving towards the device or away from it? What is the angle of motion of a person inside a closed room relative to the location of WiVi?
Enable Communication through a Wall without Carrying a Wireless Device
Wi-Vi is both a transmitter and a receiver. A human can communicate with it using simple gestures without carrying or wearing any wireless device.
Identify Simple Gestures from Behind a Wall
Wi-Vi can detect very simple gestures made through a wall, making it the first through-wall gesture-based interface.


What are the Applications of Wi-Vi?
Law enforcement: Law enforcement personel can use the device to avoid walking into an ambush, and minimize casualities in standoffs and hostage situations.
Emergency situations: Emergency responders can use it to see through rubble and collapsed structures.
Personal Security: Common users can use it for intrusion detection, or when stepping into dark alleys and unknown places.
Smart Sensing: Wi-Vi can be extended to sense motion in different parts of a building and allow automated control of heating/cooling and lighting systems.
User Interface Design: The technology may also be leveraged in the future to enable controlling household appliances via gestures, and non-invasive monitoring of children and elderly.
Entertainment: It enables a new dimension for input-output devices in gaming which does not suffer from occlusion and works in non-line-of-sight.
