AMBIENT ASSISTED LIVING: ICT-BASED SOLUTIONS IN REAL LIFE SITUATIONS

Abstract
APEX, a framework for prototyping ubiquitous environments, is used to design an Ambient Assisted Living (AAL) system to enhance a care home for older people. The environment allows participants in the design process to experience the proposed design and enables developers to explore the design by rapidly developing alternatives. APEX provided the means to explore alternative designs through a virtual environment. It provides a mediating representation (a boundary object) allowing users to be involved in the design process. A group of residents in a city-based care home were involved in the design. The paper describes the design process and lessons learnt for the design of AAL systems.

Reusing models and properties in the analysis of similar interactive devices

Authors
Harrison, MD; Campos, JC; Masci, P;

Publication
INNOVATIONS IN SYSTEMS AND SOFTWARE ENGINEERING

Abstract
The paper is concerned with the comparative analysis of interactive devices. It compares two devices by checking systematically a set of template properties that are designed to explore important interface characteristics. The two devices are designed to support similar tasks in a clinical setting. The devices differ as a result of judgements based on a range of considerations including software. Variations between designs are often relatively subtle and do not always become evident through even relatively thorough user testing. Notwithstanding their subtlety, these differences may be important to the safety or usability of the device. The illustrated approach uses formal techniques to provide the analysis. This means that similar analysis can be applied systematically.

MODUS: uma metodologia de prototipagem de interfaces baseada em modelos

Authors
Machado, Marina; Campos, José C.; Couto, Rui;

Publication

Abstract
A interface de utilizador é essencial para o sucesso de uma aplicação, ora a sua implementação requer tempo e esforço. Metodologias baseadas em modelos suportadas por uma geração automática têm sido propostas como solução para reduzir os custos de desenvolvimento. No entanto, um elevado nível de automação nestas abordagens requer o uso de modelos detalhados da interface, originando complicações. Por um lado, esta perspetiva é contrária a uma conceção baseada no progressivo refinamento de mockups, típica do desenvolvimento de interfaces. Por outro lado, obriga uma distinção entre os modelos utilizados na lógica de negócio e na interface. Este artigo propõe uma abordagem para gerar a interface de utilizador baseada diretamente em modelos estruturais da lógica de negócio. A identificação do domínio de aplicação é um factor chave da metodologia, permitindo automatizar o processo de geração. Por sua vez a separação entre conteúdo e forma favorece o refinamento iterativo das interfaces geradas.

Layers, resources and property templates in the specification and analysis of two interactive systems

Authors
Campos, José C.; Curzon, Paul; Masci, Paolo; Harrison, Michael douglas;

Publication

Abstract
The paper briefly explores a layered approach to the analysis of two interactive systems (Nuclear Control and Air Traffic Control), indicating how the analysis enables exploration of the particular features emphasised by the use cases relating to the examples. These features relate to the interactive behaviour of the systems. To facilitate the analysis, property templates are proposed as heuristics for developing appropriate requirements for the respective user interfaces.
