Researchers from Beijing Normal University and Shenyang Aerospace University in China have developed a flexible tactile sensor that can accurately read braille in real-time. The sensor uses an optical fibre ring resonator to detect the pressure exerted by raised dots on a braille surface, allowing it to quickly decode braille patterns and translate them into readable information. The team has achieved a classification accuracy of 98.57% in reading eight different arrangements of three dots and 100% in classifying signals generated by five English words.
Forecast for 6 months: The flexible tactile sensor is expected to be integrated into mobile braille readers and wearables, making it more accessible to people with visual impairments. This will lead to increased adoption of braille as a communication method, particularly among younger generations.
Forecast for 1 year: The sensor’s accuracy and speed will be further improved through machine learning model enhancements, enabling it to read braille with even higher precision. This will lead to increased adoption in educational institutions and rehabilitation centers, where braille is used as a primary means of communication.
Forecast for 5 years: The flexible tactile sensor will become a standard feature in smart canes and other assistive technologies, revolutionizing the way people with visual impairments navigate their surroundings. This will lead to increased independence and mobility for individuals with visual impairments.
Forecast for 10 years: The sensor’s technology will be integrated into implantable devices, enabling people with visual impairments to read braille directly through their skin. This will lead to a significant improvement in the quality of life for individuals with visual impairments, enabling them to read and communicate more easily and independently.
