- Abstract
The loss of vision restrained the visually impaired people from perfonning their daily task. This issue has impeded their free-movement and tumed them into dependent a person. People in this sector did not face technologies revamping their situations. With the advent of computer vision, artificial intelligence, the situation improved to a great extent. The propounded design is an implementation of a wearable device which is capable of performing a lot of features. It is employed to provide visual instinct by recognizing objects, identifying the face of choices. The device runs a pre-trained model to classify common objects from household items to automobiles items. Optical character recognition and Google translate were executed to read any text from image and conve1t speech of the user to text respectively. Besides, the user can se11rch for an interesting topic by the co1mnand in the fonn of speech. Additionally, ultrasonic sensors were kept fixed at tlu·ee positions to sense the obstacle during navigation. The display attached help in conununication with deaf person and GPS and GSM module aid in tracing the user. All these features run by voice conunands which are passed through the microphone of any ea1phone. The visual input is received tlu·ough the camera and the computation task is processed in the raspbeny pi board. However, the device seemed to be effective during the test and validation.
