RESNA 27th International Annual Confence
Image illustrates the MAG concept and the type of accessibility information that could be obtained. In this illustration, the MAG automatically finds a wheelchair user's current location through its GPS component, and then uses its wireless Internet connection to search the central server's accessibility database for nearby travel conditions. The MAG alerts the user that a sidewalk they routinely travel has been closed for construction. From the database, the MAG presents an image of the site along with text descriptions and audio playback of voice annotations.
