RF-Capture is a device that captures a human figure through walls and occlusions. It transmits wireless signals and reconstructs a human figure by analyzing the signals' reflections. RF-Capture does not require the person to wear any sensor, and its transmitted power is 10,000 times lower than that of a standard cell-phone. RF-Capture has many applications, like:

  • It can know who the person behind a wall is.
  • It can trace a person's handwriting in air from behind a wall.
  • It can determine how a person behind a wall is moving .
