Abstract

Diffusion of radio frequency identification (RFID) promises to boost the added value of assistive technologies for mobile users. Visually impaired people may benefit from RFID-based applications that support users in maintaining “spatial orientation” (Mann, 2004) through provision of information on where they are, and a description of what lies in their surroundings. To investigate this issue, we have integrated our development tool for mobile device, (namely: MADE, Bellotti, Berta, De Gloria, & Margarone, 2003), with a complete support for RFID tag detection, and implemented an RFID-enabled location-aware tour-guide. We have evaluated the guide in an ecological context (fully operational application, real users, real context of use (Abowd & Mynatt, 2000)) during the EuroFlora 2006 international exhibition (EuroFlora). In this chapter, we describe the MADE enhancement to support RFID-based applications, present the main concepts of the interaction modalities we have designed in order to support visually impaired users, and discuss results from our field experience.
