    According to the European Union, the European health care sector is still lacking adoption of healthcare standards and interoperable solutions [11] [13]. The EU expects through the exchange of interoperable health data (i) a better access for the European citizens to health services, (ii) increasing patients' sovereignty and empowerment and (iii) a better service provision through the access to health data for research and innovation, policymaking, and regulatory decisions. To address this challenge, we present in this paper some further developments of our distributed and interoperable e-health framework [47] [23] [42] [34]. We extended the architecture with a streamlined and customized design thinking process to rapidly acquire software requirements and specifications. This paper is designed as a proof-of-concept around the Horizon 2020 research project ESCAPE. User requirements and specifications were gathered using the design thinking process and implemented in the flexible architecture. The result is a comprehensive and customized clinician dashboard which is embedded in the interoperable architecture as a customized clinical solution for care managers in an intervention of multimorbid patients.

    The use of user models can be very valuable when trying to develop accessible and ergonomic products and services taking into account users specific needs and preferences. Simulation of userproduct interaction using user models may reveal accessibility issues at the early stages of design and development, and this results to a significant reduction in costs and development time. Moreover, user models can be used in adaptive interfaces enabling the personalised customisation of user interfaces that enhances the accessibility and usability of products and services. This paper presents the efforts of the Virtual User Modelling and Simulation Standardisation VUMS cluster of projects towards the development of an interoperable user model, able to describe both able-bodied and people with various kinds of disabilities. The VUMS cluster is consisted by the VERITAS, MyUI, GUIDE, and VICON FP7 European projects, all involved in user modelling from different perspectives. The main goal of the VUMS cluster was the development of a unified user model that could be used by all the participant projects and that could be the basis of a new user model standard. Currently, within the VUMS cluster, a common user model has been defined and converters that enable the transformation from each projects specific user model to the VUMS user model and vice versa have been developed enabling, thus, the exchange of user models between the projects.

    This STS on user experience and emotions for accessibility is targeted towards the elaboration on the topics of user experience and affective computing approaches and their relation to accessibility of electronic content. Accessible design as crucial condition for disabled users to get access to electronic content, which is also beneficial for non-disabled users, e.g. because of adaptability of information presentation accessing web services via smartphones. Accessibility so far pays less attention to user experience or emotional aspects of interaction, though they are important factors for disabled persons in similar way as for non-disabled persons. Additional to accessibility, considering user experience and emotional aspects of user interfaces would help disabled users for example to easily and efficiently use information systems and overcome communication disorders. Concepts for support of emotional interaction can on the other side increase the usability of electronic services for disabled users.

    Position paper: Tools for the development of accessible and interoperable services for the Web of Things

    The Web of Things is about extending the Internet of Things [Ashton 2009] concept beyond the connection of things and considering issues like heterogeneity, scalability and usability with respect to progressive computing [Mayer et al. 2013]. By introducing web technologies, the concept overpasses Machine-to-Machine (M2M) communication and incorporates interaction with users into the landscape. Until now, there is not a lot of research in this domain on developing accessible applications for people with special needs. This position paper presents our initial approach to define and implement a semantic web-based framework for interoperable and accessible services in the Web of Things, which extends previous work of the authors for web 2.0 applications.

    Research Report on User Modeling for Accessibility. Online resource

    User models are abstract representations of user properties including their needs, preferences, knowledge, as well as physical, cognitive, and behavioral characteristics. The characteristics are represented by variables. User models are instantiated by the declaration of these variables for a particular user or group of users. Such instances of user models are called user profiles. A user profile captures the kind of information about an individual user that are essential for an adaptive system to behave differently to different users. User modeling can be used to enhance the accessibility of user interfaces by generating and adapting them according to the particular user needs and preferences represented as user profiles. Different approaches have been taken in this field but further research and development is necessary, in particular to address the need for standards to support the interoperability and portability of user models across implementations. More specifically, one of the main challenges of user modeling is the absence of a common approach for integrating user profiles that support different user models within individual implementations, and for migrating profiles from one implementation to another. This can be attributed to the broad variety of user profiles and the incompatibilities that can occur among them. For example, differences in user profiles can occur due to differences in scope of the modeling, source of information for the modeling, time sensitivity and update methods of the model (static vs. dynamic model). There are many other factors that further increase the variety of models. These factors will be discussed in the following papers' descriptions presented at this symposium.

    User models can be considered as explicit representations of the properties of an individual user including users needs, preferences as well as physical, cognitive and behavioral characteristics. Due to the wide range of applications, it is often difficult to have a common format or even definition of user models. The lack of a common definition also makes different user models even if developed for the same purpose -incompatible to each other. It does not only reduce the portability of user models but also restricts new models to leverage benefit from earlier research on similar field. This chapter presents a brief literature survey on user models and concept of an interoperable user model that takes a more inclusive approach than previous research. It is an initiative of the EU VUMS c luster of projects which aims to simulate user interaction and adapt interfaces across a wide variety of digital and non-digital platforms for both able bodied and disabled users. We have already been successful to define an application and platform-independent user model exchange format and the importing of any user profile across all projects.

    This STS on Virtual User Models for designing and using of inclusive products is targeted towards generic interoperable user models that describe the relevant characteristics of users, who will interact with products and user interfaces. A user profile is an instantiation of a user model representing either a specific user or a representative of a group of users. With such a model designers can define as many user profiles as needed to address the whole range of requirements from a target population in order to maximize the level of accessibility of products and services according to the selected user profile. The papers in this STS address many of the issues addressed by the VUMS cluster of projects. The cluster is formed by four projects funded by the European Commission under the Theme "FP7-ICT-2009.7.2 Accessible and Assistive ICT"; the projects are VICON, MyUI, GUIDE and VERITAS (http://www.veritas-project.eu/vums/).

    The development of products that are accessible to the largest possible group of users can be regarded as a major challenge for manufacturers of consumer products. It is therefore crucial, that the product development process is supported by practical methods and tools that can help incorporate these essential human factors in early phases of the development process. Ergonomics evaluation and user testing with real users are user centred design methodologies often conducted by companies that are not only complex, but can be very time and cost-intensive. As an alternative approach virtual user models (VUM) have been proposed for supporting the early phases of the product development process. In this paper we will present the model-based design approach of the European research project VICON supporting inclusive design of consumer products particularly at the early stages of product development.

    In the last decade, user interfaces of consumer products have become increasingly complex. This can cause very real problems for older people and people with disabilities when buying mainstream products. It is an issue we cannot ignore as the Worlds population is ageing rapidly. Despite the market potential and social obligation, most products are developed without any consultation with older users. Furthermore user testing only typically takes place once a prototype of a product has been created or after a version of a product is already on the market. The European Project VICON aims to address these issues by developing a library of virtual users with varying levels of impairment in vision, hearing and manual dexterity that can be used to test product designs for accessibility and usability issues at early stages of the design process.
