Navatar, which is designed for people with visual impairments, identifies the position of a person via their mobile sensors. To clarify its position, the user can specify things by touching its proximity.
If indoor location systems multiply – witness the latest project of Fraunhofer, who has developed a module that adds the phone – it does not mean that they are accessible to all. So, to enable the visually impaired to take guidance systems indoors and outdoors, a team from the University of Nevada has developed a solution that combines sensors and human-computer interaction. Navatar called, the system uses 2D architectural plans, present in most buildings and basic technologies such as the accelerometer or compass, present in a large majority of smartphone.
