Bilingual wearable assistive technology for visually impaired persons

Person with visual impairment suffers from various problems and is unable to lead a normal regular life because of their blindness. In this paper, the proposal of a wearable device for visually impaired persons is presented that can detect color and speak out the name of the color in two different languages: Bengali and English, through connected headphone. Bluetooth headphone or wire headphone, even speaker can be interfaced with the proposed system. The proposed device will be able to detect color and turn the color name into sound so that visually impaired persons can recognize it. It will be implemented and developed using a microcontroller, color sensor along with an amplifier and wired or Bluetooth connected headphone. The device will employ a reliable microcontroller platform known as Arduino Nano along with Bluetooth module HC-05, color sensor TCS 3200, LM 386 power amplifier with SD card module. The device will be able to decode color information from everyday resources and convert into sound so that blind persons can easily identify any color.
