23. A method of displaying radiofrequency identification (RFID) response information, the method comprising:
-
transmitting a first RFID interrogation signal at a first signal strength; receiving a first RFID response signal conveying first identification information; transmitting a second RFID interrogation signal at a second signal strength, the second signal strength greater than the first signal strength; receiving the first RFID response signal and a second RFID response signal, the second RFID response signal conveying second identification information; presenting the first and second identification information to a user; detecting a head movement by the user; determining a gesture command from the head movement; and adjusting the presented first and second identification information in response to the gesture command. - View Dependent Claims (24)
