The current diversity of available devices and form factors increases the need for model-based techniques to support adapting applications from one device to another. Most work on user interface modelling is built around declarative markup languages. Markup languages play a relevant role, not only in the modelling of user interfaces, but also in their implementation. However, the languages used...

Procedural modelling is an attractive alternative to cut down the costs of manual content creation for virtual worlds. We discuss our declarative modelling approach to the creation of 3D virtual worlds, which integrates a variety of procedural techniques in order to enable a non-specialist user to interactively create a complete 3D virtual world in minutes. In particular, we introduce procedura...

Traditionally, the Conceptual Modelling (CM) community has been interested in defining methods to model Information Systems by specifying their data and behaviour, disregarding user interaction. On the other hand, the Human-Computer Interaction (HCI) community has defined techniques oriented to the modelling of the interaction between the user and the system, proposing a user-centred software c...

Conceptual modelling tools allow users to construct formal representations of their conceptualisations. These models are typically developed in isolation, unrelated to other user models, thus losing the opportunity of incorporating knowledge from other existing models or ontologies that might enrich the modelling process. We propose to apply Semantic Web techniques to the context of conceptual ...

As the demand for domainand formalism-specific visual modelling environments grows, the need to rapidly construct complex User Interfaces (UIs) increases. In this paper, we propose a Multi-Paradigm Modelling (MPM) approach whereby structure, visual appearance and above all reactive behaviour of a UI are explicitly modelled. These models are constructed at the most appropriate level of abstracti...

This paper presents knowledge engineering for a system that incorporates user stereotypes as well as a multi criteria decision making theory for affective interaction. The system bases its inferences about students’ emotions on user input evidence from the keyboard and the microphone. Evidence form these two modes is combined by a user modelling component underlying the user interface. The user...

In this article, model-based design and synthesis of reactive user interfaces is presented as a particular application of Computer-Automated Multi-Paradigm Modelling (CAMPaM). Multi-paradigm modelling acknowledges the need to model at different levels of abstraction, using appropriate formalisms. It also gives transformations first-class model status. In the CAMPaM UI development process, a cla...

This paper briefly presents a new information modelling methodology useful as an information systems development approach. The methodology is based on a set of fundamental abstraction mechanisms, which provide the means for modelling on a number of abstraction levels and, on the highest levels, the most invariant components and structures of the information model can be identified and defined. ...

Gamification studies in the educational domain usually focus on motivating students to increase their learning performance by enhancing motivation. Classifications of behavioural profiles are often used for this (referred as “gamer” or “user types”), which support personalization students’ experiences. These classifications consider these from gamers’ non-gamers’ points view. However, within ed...
