Visual impairment aid using haptic and sound feedback

In this paper, implementation of a wearable glove is presented that can be used to assist the visually impaired people. It can help the blind person to avoid hurdles using haptic and voice feedback. It does not only navigate the path to the blind person but also informs about his/her location to others through a message on the mobile device. It can help his/her caretaker (in case he is not near to the blind person) to locate him using the received coordinates from the communication module of glove having Global Positioning System (GPS) and Global System for Mobile Communication (GSM) technology. This wearable glove is physically realized by interfacing different sensors and communication modules with Arduino UNO. Different modes of obstacles detection and alerts are provided using various sensors and actuators to assist visually impaired person.
