Abstract
Multimodal interaction is one of the taxonomies for Human-Computer Interaction (HCI). With the introduction of multimodal interactions, input/output information is becoming associated with the different human senses so that information can be presented in the most efficient and natural way. However, in mobile communication, a number of restrictions are still remnant. Mostly, these restrictions are caused by limitations of a mobile terminal's user interfaces. This thesis introduces an architectural framework to facilitate multimodal interaction in a virtual- device environment. The framework developed is called the Multi Interface-Device Binding (MID-B) system. MID-B provides the functions and features to overcome the drawbacks of classic multimodal interaction. In the classical sense, multimodality uses a strategy that simultaneously utilises several modalities generally offered on a 'single' device. In contrast, the MID-B's mechanisms take multimodality out of the single-device scenario. In MID-B, a 'controller-device' is aware of the availability of various devices in the vicinity, each of which may host one or more user interfaces (modalities).- The capabilities of those co-located devices, together with the context in which-the user acts, are exploited to dynamically customise the interface services available. MID-B binds these devices into a virtual device to exploit their- individual user interfaces (modalities) in a combined way. This thesis describes the MID-B architecture and its mechanisms to collect the context information of 'devices' and 'users'. The thesis presents the methodologies to exploit that context information to dynamically adapt user interfaces.
