- ZeitschriftenartikelChanging Things so (Almost) Everything Stays the Same(i-com: Vol. 20, No. 3, 2021) Dolata, Mateusz; Schubiger, Simon; Agotai, Doris; Schwabe, GerhardThe deployment of mixed reality systems in professional settings demands adaptation of the physical environment and practices. However, technology-driven changes to the environment are problematic in some contexts. Specifically, face-to-face advisory services rely on scripted material routines using specific tools. This manuscript explores challenges encountered during the development of LivePaper, a mixed-reality system for supporting financial advisory services. First, the article presents a range of design requirements derived from existing literature and multiple years of research experience concerning advisory services and physical collaborative environments. Second, it discusses technical and design challenges that emerged when building LivePaper along with those requirements. Third, the article describes a range of technical solutions and new design ideas implemented in a working system to mitigate the encountered problems. It explores potential alternative solutions and delivers empirical or conceptual arguments for the choices made. The manuscript concludes with implications for the advisory services, the systems used to support such encounters, and specific technical guidance for the developers of mixed reality solutions in institutional settings. Overall, the article advances the discourse on the application of technology in advisory services, the use of mixed-reality systems in professional environments, and the physical nature of collaboration.
- KonferenzbeitragA homogeneous service framework for pervasive computing environments(10th International Conferenceon Innovative Internet Community Systems (I2CS) – Jubilee Edition 2010 –, 2010) Maffioletti, Sergio; Schubiger, Simon; Courant, Michèle; Hirsbrunner, BéatThis paper introduces a model addressing the heterogeneity problem of Pervasive Computing systems from a resource, service and context management viewpoint. The presented system architecture, called UBIDEV is a collection of abstraction services for semantic-driven management of the physical environment that provide a design methodology that allow a description of the behavior of the whole system in terms of coordinated homogeneous services. Most of the existing approaches try to hide heterogeneity using a single uniform abstraction layer like the Java VM; these models do not fit the requirements of pervasive computing systems where the dynamism and the heterogeneity if the environment need to be taken into account even at the design level. The presented model faces heterogeneity of pervasive computing systems allowing applications to be described in terms of services provided rather than their low level instantiation details. The main contribution of UBIDEV is in the holistic approach in the management of the environment from the resources, services and context viewpoint. The resulting coordination model allows applications to be described in terms of their functionality while maintaining the degree of dependence they have with the physical environment. At the application level, the provided abstractions allow to build applications that were previously seen as difficult to build: context-awareness that scale along several dimensions, resource and service management that copes with heterogeneity using an agreed semantic, holistic coordination of resources in a service-oriented abstraction model. An example application scenario is then described to underline the approach and the added value of such architecture in terms of system design and resource and service management.
