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 visitorsâ 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 systemâs 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
Design for (every)one: co-creation as a bridge between universal design and rehabilitation engineering
In this paper the authors describe a general framework for co-designing assistive devices in a horizontal user innovation network [1] by and for disabled users. This framework attempts to identify, share and use âhidden solutionsâ in rehabilitation contexts and translate them into disruptive assistive devices build with local resources. Within healthcare contexts local solutions are frequently more effective, as they reflect the physical, emotional and cognitive needs of specific patients and engage all the stakeholders in a specific local context. By using an open horizontal innovation network, where assistive devices can be easily shared and physically hacked by other paramedics, general patterns can be detected and translated into standard universal design objects. This generative design thinking approach [2] is more than feasible with digital trends like crowd sourcing, user-generated content and peer production [3]. Cheap and powerful prototyping tools have become easier to use by non-engineers; it turns them into users as well as self manufactures [4]. We discuss the different aspects of this open innovation process within a âdesign for disabilityâ context and suggest the first steps of an iterative co-design methodology bringing together professional designers, occupational therapists and patients. In this paper the authors sketch the holistic framework which starts with the innovation development and the co-creation process between these disciplines
Towards homeostatic architecture: simulation of the generative process of a termite mound construction
This report sets out to the theme of the generation of a âlivingâ,
homeostatic and self-organizing architectural structure. The main research
question this project addresses is what innovative techniques of design,
construction and materials could prospectively be developed and eventually
applied to create and sustain human-made buildings which are mostly
adaptive, self-controlled and self-functioning, without option to a vast supply
of materials and peripheral services. The hypothesis is that through the
implementation of the biological building behaviour of termites, in terms of
collective construction mechanisms that are based on environmental stimuli,
we could achieve a simulation of the generative process of their adaptive
structures, capable to inform in many ways human construction. The essay
explicates the development of the 3-dimensional, agent-based simulation of
the termite collective construction and analyzes the results, which involve
besides physical modelling of the evolved structures. It finally elucidates the
potential of this emerging and adaptive architectural performance to be
translated to human practice and thus enlighten new ecological engineering
and design methodologies

Living labs as a driver for change in regional television
Traditional television production and distribution organizations are increasingly being challenged by a rapidly changing technological environment. These evolutions force the television industry to leave their comfort zone. This context in mind, regional television broadcasters often lack the resources, knowledge and organizational flexibility to cope with this external pressure. In this paper, we discuss the use of Living Labs as âinnovation intermediariesâ and âchange facilitatorsâ that foster and enable user-centric innovation development processes, both inside and outside the organization. This phenomenon is approached from both an open innovation and a user innovation point of view. This paper considers Living Labs as open innovation ecosystems, enabling organizations to reach out and collaborate with their (potential) audience and other external actors, but also as an open âbattle arenaâ for the organization itself. The Living Lab process governs different expectations and enables conflicting opinions to come together and to steadily grow towards a mutual solution. Moreover, the innovation development process in the Living Lab seems to have innovation spill-over effects on the organizational level, catalyzing a broader organizational change
