User-centred design of flexible hypermedia for a mobile guide: Reflections on the hyperaudio experience

A user-centred design approach involves end-users from the very beginning. Considering users at the early stages compels designers to think in terms of utility and usability and helps develop the system on what is actually needed. This paper discusses the case of HyperAudio, a context-sensitive adaptive and mobile guide to museums developed in the late 90s. User requirements were collected via a survey to understand visitors’ profiles and visit styles in Natural Science museums. The knowledge acquired supported the specification of system requirements, helping defining user model, data structure and adaptive behaviour of the system. User requirements guided the design decisions on what could be implemented by using simple adaptable triggers and what instead needed more sophisticated adaptive techniques, a fundamental choice when all the computation must be done on a PDA. Graphical and interactive environments for developing and testing complex adaptive systems are discussed as a further step towards an iterative design that considers the user interaction a central point. The paper discusses how such an environment allows designers and developers to experiment with different system’s behaviours and to widely test it under realistic conditions by simulation of the actual context evolving over time. The understanding gained in HyperAudio is then considered in the perspective of the developments that followed that first experience: our findings seem still valid despite the passed time

Publishing archaeological excavations at the digital turn

This paper engages with repeated calls within archaeology for a re-envisioning of the excavation report, contextualized by the transformation of scholarly communication taking place across the humanities and social sciences. This widespread transformation is rooted in a growing interest in showing data together with synthesis and argument, the importance afforded to public engagement, and the proliferation of digital platforms that enable creative presentations of scholarly work. In this context, we discuss our experience producing an excavation report that attempts to integrate several forms of scholarly and public-facing communication on a digital platform, and aims engage audiences at multiple levels, while simultaneously facilitating data reuse and laying out the authors’ current interpretations. We consider the benefits and challenges of producing work in this way through the example of the process of producing the Gabii Project’s first volume, A Mid-Republican House from Gabii, developed through a collaboration between the Gabii Project team and the University of Michigan Press. This experience is contextualised within the broader discourse surrounding changing expectations about open access, authorship and credit, and sustainability of digital scholarship in academic publishing

Semantic framework for interactive animation generation and its application in virtual shadow play performance.

Designing and creating complex and interactive animation is still a challenge in the field of virtual reality, which has to handle various aspects of functional requirements (e.g. graphics, physics, AI, multimodal inputs and outputs, and massive data assets management). In this paper, a semantic framework is proposed to model the construction of interactive animation and promote animation assets reuse in a systematic and standardized way. As its ontological implementation, two domain specific ontologies for the hand-gesture-based interaction and animation data repository have been developed in the context of Chinese traditional shadow play art. Finally, prototype of interactive Chinese shadow play performance system using deep motion sensor device is presented as the usage example
