This paper proposes a wearable system for visually impaired people that can be utilized to obtain an extensive feedback about their surrounding environment. Our system consists of a stereo camera and smart glasses, communicating with a smartphone that is used as an intermediary computational device. Furthermore, the system is connected to a server where all the expensive computations are executed. The whole setup is capable of detecting obstacles in the nearest surrounding, recognizing faces and facial expressions, reading texts, providing a generic description and question answering of a particular input image. In addition, we propose a novel depth question answering system to estimate object size as well as objects relative position in an unconstrained environment in near real-time and in a fully automatic way requiring only stereo image pair and voice request as an input. We have conducted an extensive number of experiments to evaluate the feasibility and practicality of the proposed system which shows promising results to assist visually impaired people.
