Abstract Much research has been done on how context can be gathered and how the task of harvesting the context information can be made as easy as possible for application developers. However, less research has been done on how to design a system that adapts to the context while being active. We present contextual ConcurTaskTrees, a notation that combines the specification of dynamic context and tasks. The effect of the integration of the new notation on a current task-based approach is demonstrated and discussed. Special ...

Abstract Programs on mobile (and embedded) devices can greatly benefit from the integration of context information to create a more pleasant user experience. This is only the case when it supports and not decreases the performance of the user. It is therefore equally important to describe context as to integrate the context specification in the design of (user interfaces for) interactive systems. In this paper, we discuss the different influences that context can have on a user interface and we introduce a graphical notation that allows ...

In-vehicle interactive systems are usually spe- cialized systems that rely on a particular set of hardware and are designed to support the driver in reaching a desti- nation with his/her vehicle. Since the importance of these systems, especially when they are built to support the driver while driving, a lot of research already has been done con- cerning usability and

Appropriate selection of ICT (Information Communication Technology) tools is valuable in project development activities where an organization can setup consistent means of collaboration to ensure that all the stakeholders use specific technology. This paper presents the conceptual framework for collaboration. The collaboration framework facilitates selection of the correct ICT tools for different project development activities. It is designed using a layer based approach and divided into three layers. We believe that the use of the framework will improve the collaboration between the teams.

The broadcasting sector is facing challenging years. With the exponential growth of media content whilst consumers expect a high quality service, it is getting progressively more challenging to offer a personalized media experience. Media companies are continuously exploring novel ways to target their viewers with such a service. In this context, it is crucial for a broadcaster to get a better understanding of the targeted audience. In this paper we highlight how empathy is an essential ingredient for future personalized and interactive services and how it brings the consumer experience to an unprecedented level. Knowing how people experience different kinds of content is strategic information for a broadcaster. (Re)acting on this information potentially delivers better content targeting, enrichment and adaptation. We present an overview of the state‐of‐the art and how it is being applied in broadcasting. We illustrate this with a concrete example case of an empathic product and dis...

In model-based user interface development, models at different levels of abstraction are used. While ideas may initially only be expressed in more abstract models, modifications and improvements according to user's feedback will likely be made at the concrete level, which may lead to model inconsistencies that need to be fixed in every iteration. Transformations form the bridge between these models. Because one-to-one mappings between models cannot always be defined, these transformations are completely manual ...

With the shift of networked software applications away from the desktop computers and into home appliances comes the challenge of finding new ways to model this type of software. The most important home appliance that has new found computing capabilities is the television set. Through television people can now be participants instead of viewers, and use interactive software to enter the participative stage. Staged participatory multimedia events are a subset of this kind of interactive software that have a predefined temporal ...

Development of interactive systems and their user interfaces combines engineering and design, formal and informal development methods from different domains. Diverse models and tools can be used to support the developers' work. In model-driven development, software systems are specified systematically using dedicated models for different aspects of the system. Yet, appropriate design of user interfaces is as important as functional correctness. This workshop provides a forum of multi-disciplinary discussion on how to ...

ABSTRACT Empathy is usually associated with detection of someones feelings and acting appropriately upon this. This act creates a feeling that the empathic person understands you. In this paper we explore whether postures, which people use to detect affective state, can be used to detect feelings of someone watching TV. We report on an initial experiment in this regard that replicated a study found in literature. In this experiment we were unable to detect a correlation between postures and emotions felt while watching a short series of video fragments. We discuss potential applications of the detected postures as such and reflect on situations that might trigger emotion-related posture change.

People with dementia face a decline of their cognitive functions, including memory impairment and difficulty to orient in time and space. Assistive applications can ease the effects of dementia by assuming and supporting impaired functions. Context-awareness is an accepted paradigm for assistive applications. It enables interactive systems to react appropriately to situations that occur during daily routines of people with dementia. However, there currently is no recommended framework to view symptoms of dementia in ...

It has often been suggested that model-driven development of user interfaces amounted to producing models of user interfaces then using automatic code generation to obtain the final result. However, this may be seen as an extreme interpretation of the model-driven approach. There are examples where that approach is successful, including mobile computing and database management systems. But in many cases automatic generation may be either impossible or may limit the quality of the final interface.
