3 Proposed Method
In order to assist blind and visually impaired people in indoor navigation and facilitate
the way finding, we propose a navigation system using mobile application that detects
and reads colour targets retrieved through the integrated camera. The developed
android application named “GuiderMoi” is mainly used to assist the blind person in
indoor environment and buildings.
3.1 General Architecture
The general architecture of the proposed system based on mobile application is shown
in Fig. 1.
The colour targets are detected using the Camshift algorithm [16]. Once the colours
are determined, a comparison is made with targets in database. If the target is unrecognized, we repeat the operation from the beginning. Otherwise, we continue processing to determine the direction. Finally, once the direction is determined, a vocal
notification is launched to notify the user about his next direction.
