Smart Glove for Blind

The paper aims to present a user-friendly device for the visually challenged individuals to aid them in their navigation. It is well known that the visually impaired people find it difficult to detect obstacles in and around their surroundings and solely depend for help, be it on other individual person or device such as white cane and dog which have now proved to be quite inefficient and outdated. The device designed is a portable, low powered version and cost-efficient hand glove that is used to facilitate the visually impaired individuals to overcome the lack of visual sense and to create awareness of the unforeseen obstacle while walking and performing their everyday tasks. The glove makes use of an ultrasonic sensor that uses vibration signals to notify the user about the upcoming hurdle. The ultrasonic sensor detects the hurdle that falls within a distance of 100 cm and alerts the user about it, through a vibration. In addition to this, pulse sensor is used to monitor the heart rate of the user. If any abnormality found, the user's guardian will be alerted through a text message. Thus, the overall objective of the device is to provide a convenient and a safe method for the visually challenged individuals to overcome their difficulties in daily life without relying on others.
