Exploiting RFIDs and tilt-based interaction for mobile museum guides accessible to vision-impaired users

In this paper, we present a study aiming to investigate how tilt-based interaction, along with RFIDs for localization, can be exploited to support blind users in interacting with mobile guides. We describe the design proposed and report on a first user study, which also compared two different ways to provide audio feedback (short sounds or vocal messages) for the tilt-based interaction.
