Abstract. Navigation is an important human task that needs the human sense
of vision. In this context, recent technologies developments provide technical
assistance to support the visually impaired in their daily tasks and improve their
quality of life. In this paper, we present a mobile assistive application called
“GuiderMoi” that retrieves information about directions using color targets and
identifies the next orientation for the visually impaired. In order to avoid the
failure in detection and the inaccurate tracking caused by the mobile camera, the
proposed method based on the CamShift algorithm aims to introduce better
location and identification of color targets. Tests were conduct in natural indoor
scene. The results depending on the distance and the angle of view, defined the
accurate values to have a highest rate of target recognition. This work has
perspectives for this such as implicating the augmented reality and the intelligent
navigation based on machine learning and real-time processing.

1 Introduction
Vision is a vital human sense that plays a crucial role in the human perception of the
environment. However, for the visually impaired, this information is not generally
available through external intervention. In fact, to ensure safe and independent
mobility, people are usually dependent on external information, planned experience,
and existing technology to navigate in indoor environments or in unfamiliar outdoor. In
this context, many researchers address the issue of how to enable these individuals to
overcome the inability to navigate the environment independently and to understand
the visual scene defined by a set of components and characteristics. In this work, we are
considering to design a system that provides assistance for the visually impaired to
better navigate in both indoor and outdoor environment.
