Mobile devices are increasingly becoming part of everyday life for many different uses. These devices are mainly based on using touch-screens, which is challenging for people with disabilities. For visually-impaired people interacting with touch-screens can be very complex because of the lack of hardware keys or tactile references.

The VI application is the result of a mobile accessibility research regarding the interaction with touch-screen smartphones for blind people. Devices based on the Android platform are still not particularly accessible and usable by blind people. This application is designed to make the main phone features available in a way which is accessible for a blind user. The crucial issue concerning the lack of HW buttons is overcome using an interaction modality based on gestures, audio and vibro-tactile feedback. A set of advanced services (e.g. navigation, reading QR codes, interaction with external services via wifi) dedicated to experienced blind users is also implemented.
