The Arianna Navigation App is an app which allows the visually impaired, blind, or people with other disabilities, to move autonomously. Social integration greatly improves by allowing higher independence and autonomous mobility, factors that are a basis for active involvement in the society. It offers two main services to visually impaired people: the guiding service, for allowing the users to follow the trace deployed in the environment; the navigation service, for finding directions towards a given destination on the trace maps and retrieve other location-based information.
Arianna works as follows: the camera of the smartphone continuously captures the scene in front of the person and identifies the path by recognizing special colored strips painted or sicked to the floor. The user receives a vibration signal through his cell phone. The vibrations are related to the position and direction of the user and allow him to understand the direction to follow and the presence of path variations.
