There are many navigation systems for the visually impaired but few among them provide seamless integration of indoor -outdoor navigation. This paper reviews navigation systems that are currently available for the visually impaired and proposes the Indoor-Outdoor Vision navigation system (IO Vision) that will make navigation easier in both indoor and outdoor environments. The findings reveal that while there are many systems that support either the outdoor or indoor navigation, systems that provide seamless integration of both indoor and outdoor navigation are extremely limited. This study proposes the development of an integrated system that combines the features of indoor and outdoor systems. A long-term goal of this research is to develop a self-contained system that utilizes the principles of Geographical Positioning System(GPS)and Geographical Information System (GIS) in association with Radio Frequency Identifiers (RFID) and sensors to support the navigation of the visually impaired.
