1. A computer-implemented method comprising:

  • receiving, by a communications component of a user device and from a transmitter that is distinct from the user device, a communications signal containing one or more parameters indicating one or more characteristics of one or more power waves transmitted by the transmitter into a transmission field, wherein at least one characteristic is a power level for the one or more power waves;

    identifying, by a processor implemented in the user device located at a receiver location, an amount of energy received by a receiver coupled to the user device from the one or more power waves;

    determining, by the processor implemented in the user device using the one or more parameters, a pocket location for a pocket of energy, wherein the pocket location is where the one or more power waves having the one or more characteristics converge and constructively interfere with one another in the transmission field and the pocket location for the pocket of energy is distinct from a location of the transmitter; and

    when the pocket location has a higher power level than the receiver location, generating and displaying, by the processor implemented in the user device, a user interface having an indicator indicating a direction to the pocket location relative to the receiver location,wherein the user device is configured to receive energy from the one or more power waves at the pocket of energy to power or charge the user device.
