“…The subsequent advances in the field of mobile guides in general (Kenteris et al 2011) and for the cultural heritage sector in particular (Ardissono et al 2012), prompted the development of specific authoring tools to support the porting of prototypes to new application settings. Some tools facilitate the composition of the digital content for the personalisation of audio (Petrelli et al 2000) or context-aware video (Pan et al 2002) on mobile platforms. Other forms of authoring include the creation of a collection of multimedia pages organised in a tree-like structure (Linaza et al 2008), the filling of visual templates with contents from heterogeneous sources (Ardito et al 2012), and the authoring of complete mobile applications instead of its content alone (Economou et al 2008).…”

This paper presents an authoring environment, which supports cultural heritage professionals in the process of creating and deploying a wide range of different personalised interactive experiences that combine the physical (objects, collection and spaces) and the digital (multimedia content). It is based on a novel flexible formalism that represents the content and the context as independent from one another and allows recombining them in multiple ways thus generating many different interactions from the same elements. The authoring environment was developed in a codesign process with heritage stakeholders and addresses the composition of the content, the definition of the personalisation, and the deployment on a physical configuration of bespoke devices. To simplify the editing while maintaining a powerful representation, the complex creation process is deconstructed into a limited number of elements and phases, including aspects to control personalisation both in content and in interaction. The user interface also includes examples of installations for inspiration and as a means for learning what is possible and how to do it. Throughout the paper, installations in public exhibitions are used to illustrate our points and what our authoring environment can produce. The expressiveness of the formalism and the variety of interactive experiences that could be created was assessed via a range of laboratory tests, while a user-centred evaluation with over 40 cultural heritage professionals assessed whether they feel confident in directly controlling personalisation.

“…In the original implementation of macronodes, all linguistic adjustments of the macronode's surface form were realized through conditional text, manually specified by the content author with the aid of a macronode editor (Petrelli et al, 2000). The text was then to be read and recorded by a human actor.…”

“…This approach was particularly useful in the HIPS project as different partners developed different components: using the development environment we were able to autonomously work on rules and data (the macronode network) while simulating the user model and the localization mechanism 9 . From that experience a set of guidelines can be proposed (Petrelli et al 2000 reports the work in full, here only the most relevant points are discussed); Figure 9 visually summarizes the guidelines using HIPS as contextual example:…”

Published paperAbstract. 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.

“…The authors do not explicitly discuss relationships between user model and presentation or application model. In [13] the graph formalism is employed for modelling paths. Adaptation is specified as text composition templates with linguistic rules.…”

Abstract. In this paper we reflect the need for modelling in a systematic production of adaptive hypermedia applications. Proposed approach is based on the Unified Modelling Language (UML). State diagrams are used to model possible paths through hypertext. The user model expressed by a class diagram determines structural and behavioural features, which are used for specification of adaptations in states and transitions contained in state diagrams.
