Visual maps deliver content in a simple and effective way. They can be useful for various purposes in areas such as street guidance, surrounding information, and education. However, sightless persons are unable to explore visual maps and risk being cut off from several multimedia Web applications. In this paper, starting from accessibility issues of map-based applications, we discuss possible interaction modalities and devices to use for truly achieving usage perspectives desired by blind people. New ways to interact with a mobile device (such as gestures or touch commands) and possible solutions for making a map truly effective are investigated. In order to better explain the issues and needs of blind users accessing visual maps, an example of an interaction is presented.
