How Does RF Capture Work?
- RF-Capture transmits radio waves that pass through physical objects
- Radio signals reflect off whatever is on the other side and bounce back to RF-Capture
- RF-Capture measures the intensity of the waves, among other variables
- The device then uses a “coarse-to-fine algorithm” to create an accurate silhouette
The Technology Helps Stay Safe and Secure
“We are working to turn this technology into an in-home device that can [be called] 911 if it [is capable of detecting] that a family member has fallen unconscious,” MIT professor Dina Katabi said in a statement. “You could also imagine [the technology] being used to operate your TVs and lights, or to adjust your [temperature] by monitoring where you are in the house.”
- The current model assumes that the subject of interest starts by walking towards the device, hence allowing RF-Capture to capture consecutive RF snapshots that expose various body parts.
- While the system is able to track individual body parts facing the device, like a Palm writing in the air, it is unable to perform full skeletal tracking. It is because not all body parts of a person appear in all RF snapshots.
