A Survey of Requirements Engineering Methods for Pervasive Services

Designing and deploying ubiquitous computing systems, such as those delivering large-scale mobile services, still requires large-scale investments in both development effort as well as infrastructure costs. Therefore, in order to develop the right system, the design process merits a thorough investigation of the wishes of the foreseen user base. Such investigations are studied in the area of requirements engineering (RE). In this report, we describe and compare three requirements engineering methods that belong to one specific form of RE, namely Goal-Oriented Requirements Engineering. By mapping these methods to a common framework, we assess their applicability in the field of ubiquitous computing systems

Requirements Engineering for Pervasive Services

Developing pervasive mobile services for a mass market of end customers entails large up-front investments and therefore a good understanding of customer requirements is of paramount importance. This paper presents an approach for developing requirements engineering method that takes distinguishing features of pervasive services into account and that is based on fundamental insights in design methodology

Engineering context-aware systems and applications:A survey

Context-awareness is an essential component of systems developed in areas like Intelligent Environments, Pervasive & Ubiquitous Computing and Ambient Intelligence. In these emerging fields, there is a need for computerized systems to have a higher understanding of the situations in which to provide services or functionalities, to adapt accordingly. The literature shows that researchers modify existing engineering methods in order to better fit the needs of context-aware computing. These efforts are typically disconnected from each other and generally focus on solving specific development issues. We encourage the creation of a more holistic and unified engineering process that is tailored for the demands of these systems. For this purpose, we study the state-of-the-art in the development of context-aware systems, focusing on: (A) Methodologies for developing context-aware systems, analyzing the reasons behind their lack of adoption and features that the community wish they can use; (B) Context-aware system engineering challenges and techniques applied during the most common development stages; (C) Context-aware systems conceptualization

READ-It: Five-to-seven-year-old children learn to read in a tabletop environment

Augmented tabletops can be used to create multi-modal and collaborative environments in which natural interactions with tangible objects that represent virtual (digital) information can be performed. Such environments are considered potentially interesting for many different applications. In this paper, we address the question of whether or not it makes sense to use such environments to design learning experiences for young children. More specifically, we present the "Read-It" application that we have created to illustrate how augmented tabletops can support the development of reading skills. Children of fiveto-seven-years old were actively involved in designing and testing this application. A pilot experiment was conducted with a prototype of the Read-It application, in order to confirm that it does indeed meet the a priori expectations. We hope that the Read-It application will inspire the development of more tabletop applications that are targeted at specific user groups and activities
