Fingertip braille sensor can help elderly
SENDAI (Kyodo) A researcher at Tohoku University has created a glovelike
device that recognizes braille using fingertip sensors, a development that
could assist many seniors dealing with visual impairment.
A student demonstrates how to use a braille sensor that can be worn on a
fingertip at a lab at Tohoku University in Sendai.
The device, developed by Mami Tanaka, an assistant professor at the Tohoku
University graduate school, uses a special sensor that reads braille and
transmits the information to a computer that deciphers the dots as
characters.
Many elderly people have trouble learning braille because of the small size
prescribed for each character -- a space measuring 6.5 mm by 3.5 mm.
The Health, Labor and Welfare Ministry says only one in 10 visually impaired
people in Japan can read braille.
Tanaka has also been working on a system to vocalize braille, a study
expected to offer even greater help for the visually impaired.
The fingertip device recognizes the dots' positions, then sends the data to
a computer by changing output voltage. The information is then deciphered by
the computer, which collates the data with preregistered characters.
