Raspberry Pi Based Wearable Reader For Visually Impaired People with Haptic Feedback

摘要

Visually Impaired people report numerous difficulties with accessing printed text. The current scenario of reading for blind people is with the help of the Braille system, which is a code-system of dots represent letters of an alphabet. Not all books are written in Braille, thus a visually impaired person is limited to a countable number of books. Hence, there is a need to make a reading device that enables better manageable eyes-free operation (reading). The current work proposes a wearable reader that captures real-time images of printed text from a book using a high-resolution miniature camera. The images of the printed text are processed to convert it as a computerized text using raspberry pi microcontroller. Vibration motors were embedded in the device that guides the user to orient with the direction of reading in case they get deviated from the current text-line. The computerized text can be heard as a voice by the user. The device can be worn in finger and gain access to a various number of learning resources and can be widely used by the blind people for their studies.
