Electronic Travelling Kit for Navigation of Visually Challenged Individuals 2019-28-0162

Navigation of visually challenged persons is found tough, as they frequently do not get the essential details for escaping the perils and risk they come across when they want to reach a destination. Modernization of the world leads to the usage of technologically equipped devices to make compact and cost-effective setup. In order to help the visually impaired person to navigate securely swiftly an impediment identification system employing techno equipment such as Ultrasonic Sensors (US) and Universal Serial camera-based visual navigation system is proposed. The proposed framework identifies obstruction via the US and transmits audio signals as feedback to guide the individual about the location to be reached. Moreover, for capturing the location where the person has to move a universal serial bus (USB) webcam is employed. USB webcam is also deployed to distinguish between a human and an obstacle. In order to identify the persons well known to the visually challenged and also the presence of other human movements a face recognition system using image processing is adopted in the proposed system. The General Packet Radio Service (GPRS) aids in giving the directions and the current location of the person with the Google map voice command. Bluetooth low energy (BLE) and Radio Frequency Identification (RFID) technology are being used for indoor navigation. Bluetooth beacons are used to trace the user exact location and the user is also guided to reach the destination by placing RFID tags at different sites. A cost-effective electronic traveling aid using voice and GPRS support is proposed.
