Embodiment Construction

[0029] [029] FIG. 1A shows a user 101 wearing elements of a management and navigation system applied to the blind. In FIG. 1A , a user 101 is shown wearing a communication module 102 , ankle modules 151 , 152 and a headset 160 . Also shown is module 153 mounted on the cane. Communication module 102 , ankle modules 151 , 152 and headset 160 allow user 101 to walk by following the track of radio frequency identification tag 170 as described below.

[0030] [030] The ankle modules 151, 152 (and, optionally, the cane-mounted module 153) read the radio frequency identification tag 170 and pass information from the radio frequency identification tag 170 to the communication module 102. The communication module 102 uses the information from the radio frequency identification tag 170 to determine the direction, speed and path of travel of the user. The communication module 102 provides audio direction information and route finding information to the user 101 using the earphone 160 ....

Abstract

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.

Description

technical field [0001] [001] The present invention relates to a computer aided navigation and life management system for the blind. Background technique [0002] [002] Blind people live in a different world. The simple act of walking from one place to another becomes difficult and often dangerous. Walking canes and guide dogs help avoid some obstacles, but don't solve the larger problem of navigating and perceiving the environment (say, there's a window on the left, a table on the right, etc.). Other issues are reading signs and printed matter. Surprisingly, very few blind people read Braille. So, for example, in an unfamiliar building, the simple act of pressing the correct elevator button for the desired floor can be a difficult task. Contents of the invention [0003] [003] These and other problems can be solved by computer-aided communication and navigation systems, which employ a computer or other processor to communicate wirelessly with radio-frequency identifica...
