ZU: sistema para auxiliar pessoas portadoras de necessidade especial visual no reconhecimento de objetos

Abstract

Integrants of the community of visually impaired people face constant problems with locomotion and have remained dependent on tools that are mostly limited (such as high prices for guide dogs) and analog (such as walking sticks), and even with increasing investments in technology and innovation, previously developed systems to solve these problems usually have limitations of functionality or orthodox methods and of unsatisfactory accessibility or usability for the public. We present, therefore, Zu, a system for mobile environment that will have an integration of tools to facilitate the locomotion of the blind and visually impaired, using the YOLO (You Only Look Once) object recognition system for detection and classification of obstacles and the standard Android phone voice synthesizer system in an interface that reads the environment around the user collecting visual information through the camera and gives the user data about any and every object or obstacle found through the audio interface. The system architecture allows the information to be passed quickly to the user in a simple and efficient way, with a variant but low delay, due to the fact that the process of detecting and classifying objects and image processing will be performed in an external server, that will send the information to the clients, so that they inform the user then.
