Abstract: Individuals with visual impairment have lost the most important perceptive sensory ability in our visually dominated world. To improve their everyday life, assistive technology (AT) for individuals with visual impairment has attracted increasing attention from researchers. Navigation systems for the visually impaired (NSVI) and sensory substitution have been two active research topics. This paper presents a comprehensive survey on the development of NSVI technology in the last five years. Two sensory substitution mechanisms, which have been generally applied in NSVI, are discussed. Three navigation methodologies are presented, namely, positioning system-based, RFID tag-based, and vision-based methods, respectively. A research proposal is presented.
