Navigation Aid for the Blind P12015

1. Navigation Aid for the Blind P12015 Faculty Guide: Dr. DeBartolo Clientele: Blind and hard of hearing individuals Team Members: (from left to right) Project Description: Navigating unfamiliar buildings can be difficult for a vision/hearing-impaired individual. While room numbers are usually in Braille only about ten percent of blind individuals read Braille. Additionally, floor maps are usually not in relief and thus impossible for the blind to read. The purpose of this project was to develop a handheld navigation system for vision/hearing-impaired individuals. The device uses radio-frequency identification (RFID) tags to calculate positionsand the quickest routes to destinations. Project Requirements: • Must be untethered • Charge in less than 8 hours • Changeable battery • Commands to user must be non-visible • Device generates less than 50 db at three feet • Impact resistant • Hands free • Attachment time less than one minute • Reliable • Lightweight ELECTRICAL SYSTEMS MECHANICAL SYSTEMS • MAIN CASE: • Slide allows for easy batter access • Top cover holds keypad in place • Main body holds PCB, RFID reader, and battery in place SOFTWARE SYSTEMS • MOTOR CASES: • Transmits vibrations • Allows offset mass to rotate TESTING/FUTURE DEVELOPMENTS
