Abstract
Disclosed are systems and techniques for transferring device content using radio frequency (RF) sensing. For instance, a first wireless device can identify a first user of the first wireless device based on a first radio frequency (RF) signature associated with the first user. The first wireless media device can determine a disengagement of the first user from the first wireless media device. In response to the disengagement, content information associated with usage of the first wireless device by the first user can be captured.
Claims22
A first wireless device, comprising:
- at least one memory;
- at least one transceiver;
- and
- at least one processor coupled to the at least one memory and the at least one transceiver, the at least one processor configured to:

- determine a first RF signature associated with the first user based on the first set of RF sensing data;
- identify the first user based on the first RF signature associated with the first user;
- determine a disengagement of the first user from the first wireless device;
- in response to the disengagement, capture first content information associated with usage of the first wireless device by the first user;
- transmit, via the at least one transceiver, the first content information and an indication of the first RF signature associated with the first user to a second wireless device;
- obtain a second set of RF sensing data associated with at least a second received waveform corresponding to the first transmitted waveform reflected off of a second user of the first wireless device;
