A computer-aided communication and navigation system that uses a computer or other processor in wireless communication with Radio Frequency Identification (RFID) tags to aid a blind person. A communication module worn by the user receives information from one or more RFID tags readers and provides audio and, optionally, stimulatory information to the blind person. In one embodiment, a tag reader is provided in a walking cane. In one embodiment, tag readers are provided in one or more ankle bracelets or shoes. In one embodiment, a wireless (or wired) earpiece is provided to provide audio information to one or both ears. In one embodiment, audio information is provided through one or more transducers that couple sound through bones. The use of bone coupling allows the blind person to hear the sound information from the communication module in concert with normal hearing. The tag readers provided to the ankles or shoes communicate with the communication module to allow the blind user to navigate by following a "trail" of RFID tags.
