14 DAY TRIAL // Researchers from MIT have created a special device that emits WiFi-like radio signals capable of detecting objects and movements through solid objects like walls.
This new project started in 2013, called RF-Capture, is only in its early stages of development, but researchers are optimistic they'll be able to create a device that works with a high degree of accuracy.
Right now, only basic figure detection and small gestures can be tracked with RF-Capture.
The device practically works as a 3D scanner, using radio signals to create a map of nearby surroundings. Because radio waves have the ability to go through walls, the device also tracks small reflections coming from objects that are not directly in its path.
Despite having a lower accuracy at this point in its evolution, the device is quite usable even in its current stage of development.
RF-Capture is ideal for smart IoT-enabled homes
Such a device, if used in conjunction with various smart home systems, can track persons through rooms, and help turn on or off various home functions, without needing to deploy sensors in every room of the house.
"We’re working to turn this technology into an in-home device that can call 911 if it detects that a family member has fallen unconscious," said Dino Katabi, director of the Wireless@MIT center and co-author on the RF-Capture project. "You could also imagine it being used to operate your lights and TVs, or to adjust your heating by monitoring where you are in the house."
Besides homes and offices, RF-Capture can also be useful for the gaming and movie filming industry.
Its innovative human and motion tracking system will allow a broader horizon when designing VR accessories and motion capturing equipment.
As for people who might fear the extra radio wave pollution in their homes, researchers say that the device only radiates 1/10,000 the amount given off by a standard mobile phone.
