Radio frequency identification aiding the visually impaired with synchronous sound skins
First Claim
1. A method for radio frequency identification aiding the visually impaired, the method comprising:
- storing a recording of a sound representing at least one attribute of an object having associated with the object a radio frequency identification (“
RFID”
) tag, wherein the recording includes timing information for synchronous playback;
wherein the timing information comprises a playback rate;
activating the RFID tag with an electronic travel aid (“
ETA”
) for the visually impaired including receiving information from the RFID tag;
retrieving the recording from storage; and
playing the recording synchronously through an audio interface of the ETA including;
measuring elapsed playback time;
selecting a start time in advance of a current elapsed playback time;
identifying, in dependence upon the selected start time and the playback rate, a start point in the recording that corresponds to the selected start time; and
when the elapsed playback time matches the selected start time, beginning playback of the recording from the start point.

Abstract
Methods, systems, and products for radio frequency identification aiding the visually impaired, storing a recording of a sound, including timing information for synchronous playback, representing at least one attribute of an object having associated with the object a radio frequency identification (“RFID”) tag; activating the RFID tag with an electronic travel aid (“ETA”) for the visually impaired; retrieving the recording from storage; and playing the recording synchronously through an audio interface of the ETA. Storage of sound recording may be local or remote, and sound recordings may be sorted or indexed and retrieved from storage according to an RFID tag identification code, a classification code for the object, and a type code (a sound skin identifier) for the recording.
