The idea of UIIFace is based on the open interface framework [25], which describes a framework for the development of multimodal input interface prototypes. It uses components that can represent different input modalities as well as user interfaces and other required software pieces in order to create and control a certain application. In contrast to this approach, UIIFace is a Web-based approach implemented on top of modern HTML5 [15] functionalities. Furthermore, it provides a command line interface to the Web-based GUI, which allows for the creation of stand-alone applications outside of the browser window. For the set of uni- and multimodal commands that can be used for I-SEARCH interfaces, the results of Chang [5] as well as the needs derived from the creation
of multimodal search queries are used.
