VoiceXML enables us to describe speech grammar, dialogue control, and some other elements that are required for web services by telephone, however, its target modalities are limited only to speech and DTMF. Moreover, when system developers need additional modalities, they can hardly change the language specification. Thus, in VoiceXML, it is difficult to deal with multimodalities. From this background, we have developed a multimodal interaction description language XISL. XISL has such merits as: 1) it can expand modalities available without changing its specification, 2) it enables us to reuse both XML contents and XISL interactions independently. Key words : XML, XISL, multimodal interaction, interaction description language
