This presentation is in the context of my Ph.D thesis on navigational aids for visually impaired people in indoor environment using robot. Navigational aids for the visually impaired is an active research topic in recent years. In this presentation, I will first introduce and present related works to the problem of aiding the visually impaired to navigate in environment. The analysis of each method makes motivations to propose an approach for navigational aids using Robot. I will then explain the general framework of my proposed system which includes main modules: localization, obstacle avoiding, human-machine interaction and navigation in narrow environment. My works focus on: i) improving the localization precision thanks to scene classification step using GIST features in the traditional FAB-MAP; ii) making comparative analysis for object detection in obstacle avoidance task; iii) improving navigational aid using Kalman filter; iv) proposing a simple but efficient method for human robot interaction. The experiments have been carried out with numerous scenarios with blind pupil of Nguyen Dinh Chieu School for Blind in corridor of MICA, HUST, shows the feasibility of the proposed system in reality.
