A Haptic Feedback Glove Based on Arduino for the Welfare of Unsighted People

The paper presents an Arduino-based smart hand glove-like appliance that supports blind people. Due to vision loss, blind people have to tolerate their own inhabit. The work aims to enable unsighted people to move faster and confidance. The smart hand glove is designed with the help of Arduino UNO and HC SR04 ultrasonic sensor. The ultrasonic sensor detects any hurdle in the path of blind people. The appliance detects hurdle in two sections. One section is in front of the person and other section at a certain level below the hand. The hand gloves can detect the obstacle up to a distance of 0-30 cm with a very high response. However, at 450 cm or beyond the ultrasonic sensor does not show any detection. If any obstacle is found by the glove that will immediately indicate the output of the device (buzzer, vibrating motor). In vertical direction sensor detects an object up to a distance of 58 cm. In addition, at the output GSM and GPS, modules are connected. In an emergency, the message can be received by connected people, and also the location of the blind people can be tracked. The smart hand glove ensures the safety and security of the visually disabled person.
