Multimodal interfaces provide more flexible and compelling interaction and can enable public information kiosks to support more complex tasks for a broader community of users. MATCHKiosk is a multimodal interactive city guide which provides users with the freedom to interact using speech, pen, touch or multimodal inputs. The system responds by generating multimodal presentations that synchronize synthetic speech with a life-like virtual agent and dynamically generated graphics. | MATCHKiosk A Multimodal Interactive City Guide Michael Johnston AT T Research 180 Park Avenue Florham Park NJ 07932 johnston@ Srinivas Bangalore AT T Research 180 Park Avenue Florham Park NJ 07932 srini@ Abstract Multimodal interfaces provide more flexible and compelling interaction and can enable public information kiosks to support more complex tasks for a broader community of users.

These include self check-in at airports ticket machines in railway and bus stations directions and maps in car rental offices interactive tourist and visitor guides in tourist offices and museums and more recently automated check-out in retail stores. The majority of these systems provide a rigid structured graphical interface and user input by only touch or keypad and as a result can only support a small number of simple tasks. As automated kiosks become more commonplace and have to support more complex tasks for a broader community of users they will need to provide a more flexible and compelling user interface. One major motivation for developing multimodal interfaces for mobile devices is the lack of a keyboard or mouse Oviatt and Cohen 2000 Johnston and Bangalore 2000 . This limitation is also true of many different kinds of public information kiosks where security hygiene or space concerns make a physical keyboard or mouse impractical. Also mobile users interacting with kiosks are often encumbered with briefcases phones or other .
