1. A device, comprising:
a receiver configured to receive a signal from a transmitter in an environment, wherein the signal encodes digital information specific to the transmitter that varies according to an observation angle of the transmitter mapping to the receiver; and
one or more processors configured to:
estimate distance and direction of the transmitter in the environment based at least in part on the received signal evaluated with respect to the observation angle mapping to the transmitter; and
process the encoded digital information in the signal based at least in part on the estimated distance and direction of the transmitter to display virtual content corresponding to a location of the transmitter in the environment.
