Bruce Walker and others at the Georgia Institute of Technology in the United States have developed a portable device for blind people to transmit soft bass directly to the inner ear of the blind to help the blind walk in the city.
The device uses a processor in the backpack to synthesize GPS positioning data and data from cameras and sensors on the user's helmet to determine which direction the user should go in order to reach the desired destination. Ground. The device then emits a series of "beep" sounds to guide the user.
Such a device can make the "beep" sound appear to come from a particular direction by changing the time and intensity of the sound vibrations that are passed into each earpiece. For example, to make the sound sound like it is clearly coming from the right side, the right earpiece will vibrate more loudly. The earpiece is placed under each earlobe, and the sound is transmitted directly to the inner ear without vibrating the skull through the outer ear.
As a special group in the society, the blind people need the society to give them more care and care so that they can live a better life independently. How to walk safely is the biggest problem in the life of the blind. Through the summarization of the advantages and disadvantages of various blind guide products in the past, the new device accuracy is compared with the existing sound guide system using the “information†direction of the speech method. Better.
