Inputs and outputs are not two independent phenomena in multimodal systems. This paper examines the relationship that exists between them. We present the results of a Wizard of Oz experiment which shows that output modalities used by the system have an influence on the users' input modalities for a large category of users. The experiment took place in a(More)
—This article describes our approach towards the specification and realization of interoperability within Next Generation Ambient Intelligent Environments (NGAIE). These are populated with numerous devices and multiple occupants or users exhibit increasingly intelligent behaviour, provide optimized resource usage and support consistent functionality and(More)
Location-aware ambient environments are relevant in designing interactive virtual characters. However, they raise several questions about spatial behaviors to be displayed by virtual characters, and about the perception of virtual characters by users. We designed a location-aware virtual agent that adapts its spatial behavior to users' and objects'(More)
