- 3. ABSTRACT: Visually impaired people report numerous difficulties with accessing printed text using existing technology, including problems with alignment, focus, accuracy, mobility and efficiency. We present a finger worn device that assists the visually impaired with effectively and efficiently reading paper-printed text.
- 4. INTRODUCTION: Braille is the standard tactile reading tool used by the blind for printed text, and the system is credited for boosting literacy levels among the visually impaired. However, many books and materials are still not available in Braille. Dr. Pattie Maes, founder and director of the MIT Media Lab’s Fluid Interfaces research group, who developed FingerReader.
- 5. INTRODUCTION (Contd….) The FingerReader is a 3D printed ring-like device worn on the index finger. It has a small camera on top which scans printed text and monitors finger movements.
- 6. TECHNOLOGIES USED: Hardware Details: The FingerReader hardware was designed using: 1.Multimodal feedback via vibration motors. 2. A new dual-material case design. 3. A high-resolution mini video camera.
- 8. Software Details: To accompany the hardware, a software stack that includes. 1. A text extraction algorithm. 2.Hardware control driver. 3. Integration layer with Tesseract OCR. 4. Flite Text-to-Speech (TTS)
- 10. WORKING: If the user veers away from a text line, tactile feedback is provided by two vibration motors embedded in the 3D printed case. Auditory cues alert the user at the beginning and the end of reading passages.
- 11. A novel-tracking based algorithm extracts text locally and sequentially, rather than in whole text blocks and pages like many existing devices use.
- 13. ADVANTAGES: The Finger Reader wearable health device can help them gain access to a greater number of learning resources and contribute greatly to their quality of life. The index-finger worn device is “a lot more flexible, a lot more immediate than any solution that they have right now,”
- 14. CONCLUSION: FingerReader presents a new way for VI people to read printed text locally and sequentially rather than in blocks like existing technologies dictate. The design is motivated by a user needs study that shows the benefit in using continuous multimodal feedback for text scanning, which again shows in a qualitative analysis we performed.
