1 - A CSCW Requirements Engineering CASE Tool: Development and Usability Evaluation

An experiment was performed in order to assess the usability of CSRML Tool 2012 (CT’12), a tool to specify the requirements of CSCW systems. The effectiveness and efficiency of CT’12 were evaluated by means of several experimental tasks. Moreover, the user’s satisfaction was evaluated by using both a classical survey and analyzing the participants’ facial expressions when performing the experiments. Furthermore, this evaluation has been reported by using the ISO/IEC 25062:2006 [2], thus making its results comparable with other usability assessments which follow this international standard. Finally, details about how to develop a CASE toll for a Domain Specific Language was provided in a tutorial style.

2 - Analyzing the Understandability of Requirements Engineering Languages for CSCW Systems: A Family of Experiments

Context of the proposal: Collaborative Systems
Nowadays, even classic applications like text processors are collaborative. For instance, Google Docs [2] enables several users to edit a text document simultaneously . These collaborative text processors are a good example of CSCW (Computer Supported Cooperative Work) systems [3], which are systems whose users can perform collaboration, communication and coordination tasks (3C). Collaborative systems, in a similar way to classical single-user systems, have to be specified by means of a set of requirements, whose accuracy and suitability are key to achieve the quality of the developed system. The main difference between the requirements of single-user systems and CSCW systems is the highly non-functional nature of the latter, because of the users’ need of being aware of the presence of other users with whom to perform the above mentioned 3C tasks, that is, the Workspace Awareness (WA). In order to deal with the specification of this special type of systems, we conducted several empirical evaluations in order to check which is the most adequate Requirements Engineering technique to model both awareness and quality requirements of CSCW systems. We concluded that the i* Framework [1], was the most promising one. However, we identified several issues when modeling collaborative systems with this language that led us to extend the original i* language by creating CSRML (Collaborative Systems Requirements Modeling Language) [4] and evaluate it empirically.

3 - CSRML Tool: una Herramienta para el Modelado de Requisitos de Sistemas Colaborativos

Cada vez más aplicaciones incluyen algún tipo de soporte a la realización de tareas colaborativas. Como para cualquier otro tipo de sistema, una especificación de requisitos precisa es uno de los pilares básicos en el desarrollo de este tipo de sistemas con soporte a la colaboración. Sin embargo, este tipo de sistemas poseen un tipo especial de requisitos difícil de especificar con las técnicas de Ingeniería de Requisitos (IR) tradicionales. Estudios experimentales previos muestran que la especificación del conocimiento o la percepción de una situación o hecho (awareness), necesarios para que los usuarios puedan llevar a cabo tareas colaborativas, puede ser excesivamente compleja, o incluso incompleta, cuando se usan la técnicas clásicas de IR. Para solventar este problema, se ha desarrollado CSRML (Collaborative Systems Requirements Modeling Language), una extensión del lenguaje orientado a objetivos i* para especificar requisitos de sistemas colaborativos. En este trabajo se presenta CSRML Tool: una herramienta que da soporte al lenguaje CSRML. Gracias a esta herramienta, se podrán modelar los distintos diagramas que conforman la especificación de los requisitos de un sistema colaborativo utilizando CSRML, así como comprobar la validez de los mismos con respecto al meta-modelo de CSRML.

5 - An Interactive Fuzzy Inference System for Teletherapy of Older People

The progressive aging of the population in developed countries is becoming a problem for healthcare systems, which must invest ever higher sums in caring for their older citizens. One of the most important issues in this area involves the physical and cognitive problems associated with growing old. In order to reduce the effect of these problems, gerontechnology has emerged as one of the most promising alternatives, especially in the field of the telerehabilitation systems developed to date. However, most of these systems do not offer therapists the facilities to design therapies adapted to individual patients. This paper proposes a novel system that supplies this need and enables therapists to create bespoke motor therapies as state diagrams and manage them efficiently in a collaborative setting. The proposed system is equipped with a fuzzy-based decision-making component that therapists can use to control transitioning between states according to variables such as fatigue and performance. Therefore, the system makes it feasible to provide older patients with the treatment they need in their own homes while its effectiveness is controlled by a Fuzzy Inference System.

6 - Applying thematic analysis to define an awareness interpretation for collaborative computer games

Indices de calidad: Índice de impacto: 1.569, Q1 Posición que ocupa la revista en la categoría: 16/106 Número de citas: 3 Context Collaborative computer games have evolved from single-player to massively multiplayer awareness-demanding games, usually involving collaboration to achieve team goals. As a consequence of such evolution, these players should be provided with awareness information that enables them to perform collaborative tasks with other team members. Objective The objective of this work is the analysis of current awareness interpretations in order to develop an awareness interpretation that collects the awareness needs of such games. Method This analysis has been conducted by means of a step-by-step Thematic Analysis of current interpretations that led us to extract the most relevant awareness elements defined in existing interpretations. The developed awareness interpretation was empirically evaluated by means of several surveys aimed at assessing whether the implementation of the interpretation elements in a game would improve the players enjoyment. Results The Thematic Synthesis Analysis concluded that none of the current awareness interpretations can deal properly with collaborative computer games, specifically due to collaboration and social & group dynamics. This Thematic Synthesis Analysis led us to coin Gamespace Awareness, a new awareness interpretation based on a combination of the previously analyzed awareness interpretations, which is suitable for collaborative computer games. The interpretation was positively evaluated for two games, namely a first person shooter and a real-time strategy game. Conclusions Gamespace Awareness combines the potential awareness elements needed for collaborative computer games, making it possible to identify the awareness requirements of these games from the very beginning.

7 - Past and future of software architectures for context-aware systems: A systematic mapping study

There is a growing interest on context-aware systems in recent years. Con-text-aware systems are able to change their behaviour depending on new conditions regarding the user, the platform and the environment. These sys-tems are evolving towards interacting with the user in a transparent and ubiq-uitous manner, especially by means of different types of sensors, which can gather a wide range of data from the user, the platform the user is interacting with, and the environment where such interaction is taking place. It is worth noting that the software architecture of a system is a key artefact during its development and its adaptation process. Hence, the definition of the soft-ware architecture becomes essential while developing context-aware systems since it should reflect how the context is tackled for adaptation purposes. With the aim of studying this issue, we have designed and conducted a sys-tematic mapping study to provide an overview about the different architec-tural approaches used in context-aware systems. One of the main findings of this study is that there are not many software architecture proposals that deal with context-awareness in an explicit way during the adaptation process. It was also detected that there are Human Computer Interaction (HCI) works that focus on context-aware adaptations but neglect partially or completely any possible change in the system architecture during the adaptation process. Due to this, we perceived a need to analyse what research works highlight the use of context and its relationship to the software architecture in existing context-aware systems. Therefore, this mapping study attempts to bridge the gap between Software Architecture and HCI in order to align the adaptation at the architectural level (changes in the configuration of architectural com-ponents) and at the HCI level (changes in the interaction modality or the user interface in general).
