RF and RFID Based Object Identification and Navigation System for the Visually Impaired

摘要

The proposed model taps into the acoustic abilities of a Visually Impaired Person(VIP). An RFID based system is used to help the VIP identify any particular object of his need. In addition to RFID module, an Ultrasonic sensor is used to avoid obstacles and to provide various feedback for pinpointing the object. A series of acoustic actuators is used to trigger the required navigation for the VIP. The model uses two-way localization, one using acoustic stimuli and the other using RFID. The proposed model provides an affordable solution to the existing problem of lack of sophisticated technological assistance to the VIPs.
