Abstract. Fast production of a solution is a necessity in the world of competitive IT consulting business today. In engagements where early user interface design mock-ups are needed to visualize proposed business processes, the need to quickly create UI becomes prominent very early in the process. Our work aims to speed up the UI design process, enabling rapid creation of lowfidelity UI design with traditional user-centered design thinking but different tooling concepts. This paper explains the approach and the rationale behind our model and tools. One key focal point is in leveraging business process models as a starting point of the UI design process. The other focal point is on using a model-driven approach with designer-centered tools to eliminate some design overheads, to help manage a large design space, and to cope with changes in requirements. We used examples from a real business engagement to derive and strengthen this work.
Abstract. Steerable Interfaces are emerging as a new paradigm used in realizing the vision of embodied interaction in ubiquitous computing environments. Such interfaces steer relevant input and output capabilities around space, to serve the user when and where they are needed. We present an architecture and a programming framework that enable the development of Steerable Interface applications. The distributed multi-layer architecture provides applications with abstractions to services of several novel components -for instance, steerable projection, steerable visual interaction detection, and geometric reasoning. The programming framework facilitates integration of the various services while hiding the complexity of sequencing and synchronizing the underlying components.
As collaborative environments evolve beyond the desktop, we see the emergence of a new class of augmented collaborative spaces that employ various devices and technologies to merge electronic information with physical space to support collaboration, both local and remote. To be effective, such spaces should give people the flexibility to combine their individual resources with the resources available in the space, while presenting appropriate information, taking into account the larger process within which a collaborative activity takes place. This demands richer ways of capturing content and actions, new ways of presenting multimodal information, and developing an architecture and infrastructure that unifies individuals, spaces, and processes to facilitate collaboration. Our work in steerable interfaces represents a first step in this direction.
