Summary: The area of programming learning can take advantage of the principles of
CSCW. Thus, there exist several systems that have approached to these
difficulties. However, awareness support is quite limited in most of these
systems. The COLLECE system is one of such tools as it was developed with the
goal of supporting synchronous collaborative programming tasks. In this work,
an experience of evaluation of this tool is described. Such evaluation focuses
on the elements of awareness support that COLLECE includes. The study puts
together several techniques for the evaluation of interactive systems, such as
questionnaires, empirical testing, heuristic evaluation and eye tracking. The
combination of all these techniques has allowed us to carry out a complete
analysis of the COLLECE system and its awareness support.

Summary: Cerebral palsy (CP) is a general term for a group of permanent,
non-progressive movement disorders that cause physical disability in
development, mainly in the areas of body movement but it might also affect
intellectual capabilities. Among all this diversity of profiles, we find that,
for some of them, access to a computer application is almost impossible in
spite of the great variety of commercial devices based of different
technologies. Kinect might be a viable possibility in order to facilitate
access to games and computer applications that help users improve their skills
or communication.

Summary: Mobile device usage has become part of our daily routine. Our interest is
centered on their use in teaching-learning contexts: the so-called m-learning.
In this work we try to empirically analyze the use of these portable devices
for accessing learning materials. To this end, two empirical studies have been
conducted with the aim of analyzing the effectiveness of several interaction
devices for supporting study tasks. In an initial experiment we compared
conventional access, by means of a desktop computer, with the access through
mobile phones. A replica of this first experiment was conducted to compare
these two devices with the use of tablet devices. In both experiments we use
several sources of information: subjective perception of the students, their
profiles, their performance on a study task, as well as the physical evidence
provided by an eye tracker. The results obtained allowed us to conclude that
the use of devices with visualization limitations (such as mobile phones) is
not suitable to access and visualize learning materials, due to the fact that
they impose an additional cognitive load. The results also indicate positive
perception of the use of PCs and iPads for studying, although the latter is
considered more motivating for learners.

Summary: This paper deals with a new strategy to evaluate a Natural Language
Processing (NLP) complex task using the Turing test. Automatic summarization
based on sentence compression requires to asses informativeness and modify
inner sentence structures. This is much more intrinsically related with real
rephrasing than plain sentence extraction and ranking paradigm so new
evaluation methods are needed. We propose a novel imitation game to evaluate
Automatic Summarization by Compression (ASC). Rationale of this Turing-like
evaluation could be applied to many other NLP complex tasks like Machine
translation or Text Generation. We show that a state of the art ASC system can
pass such a test and simulate a human summary in 60% of the cases.

Summary: The application of the Ambient Intelligence (AmI) approach implies the use
of new styles of computer-human interaction as well as the need of supporting
activities of collaborative nature. In these contexts, the concept of implicit
interaction refers to those actions that a computer considers as inputs
although the user has not intended to generate an input in an explicit way. In
order to provide AmI scenarios in which collaborative activities takes place
with computational support, classic concepts about computer-human interaction
are not enough, for example, when giving support to awareness. Thus, in this
paper a framework for the design of awareness support in collaborative AmI
applications is proposed. This framework takes the work by Gutwin and Greenberg
on explicit interaction as a starting point and intends to serve as a design
guide for developers who need to create such a system. Also, this work settles
the basis for a future model-based development method for collaborative AmI
systems that takes into account awareness issues.

Summary: In this paper, a learning project is explained which is being carried out at
the school of computer science at the University of Seville. The aim is that
students receive knowledge of assistive technologies when in fact there is no
this discipline in our curricula. So the best way, it is programming final
studies projects in this field. We want to make the projects have a real
application and can solve difficulties that children with Cerebral Palsy have
in their daily activities in the school.

Summary: In this paper we propose an assessment of biosignals for handling an
application based on virtual keyboard and automatic scanning. The aim of this
work is to measure the effect of using such application, through different
interfaces based on electromyography and electrooculography, on cardiac and
electrodermal activities. Five people without disabilities have been tested.
Each subject wrote twice the same text using an electromyography interface in
first test and electrooculography in the second one. Each test was divided into
four parts: instruction, initial relax, writing and final relax. The results of
the tests show important differences in the electrocardiogram and electrodermal
activity among the parts of tests.

Summary: Awareness is defined as the perception of the activities being carried out
by members of a team in a given context. The use of awareness support
techniques reduces the effort needed to realize communicative and collaborative
tasks. Therefore, this leads to an increase in group work productivity. In this
article we propose a conceptual framework which improves upon the process of
building interactive collaborative systems as proposed by CIAM (a
methodological framework for designing interactive applications for group work)
by taking the dimension of awareness into consideration.

Summary: The design and development of groupware systems is a difficult task,
especially due to their multidisciplinary nature and the technical complexity
of these kinds of systems (e.g. distribution, data sharing, multi-user
interfaces). A model-driven development approach could help to deal with this
research problem. This paper presents an approach to tackling the design and
development of groupware applications. This approach is part of a framework for
the model-based user interface development of collaborative applications
(called CIAF; Collaborative Interactive Application Framework), which includes
issues of particular relevance based on the use of several models and notations
for representing the collaborative and interactive aspects of this kind of
systems.

users are the people with disabilities. A high degree of customization is
possible in the software. So the user can selected the color of buttons,
position of system on screen, the kind of scanning, timer, the interface of
communication, etc. Five people without disabilities tested our system. The
results of the tests show the application reduce the fatigue of user and
increased the text entry rate.

Summary: This paper describes a system composed by predictive text input software
called "Dasher" and a hardware used to connect an accelerometer to the
computer. The main goal of this work is to allow people with motor disabilities
to have a flexible and cheap way to communicate. The accelerometer can be
placed on any body part depending on user preferences. For this reason
calibration functionality has been added to dasher software. The calibration
process is easy and requires only some minutes but it is necessary in order to
allow system can be used in different ways. Tests have been carried out by
placing the accelerometer on the head. A rate of 26 words per minute is
reached.

Summary: Describing CSCL scenarios can be performed in a standard way. To do so,
Instructional Design or so called Learning Design (LD) can be used for
describing CSCL scenarios by mean of a de facto specification known as IMS
Learning Design (IMS-LD). A typical teaching/learning scenario based on this
specification implies the use of several tools which must interact all
together. This paper will show a set of tools that enriches the learning
scenarios based on IMS-LD. The tools we are developing allow graphical editing
of instructional design, a generic engine and a customizable player.

Summary: The standardization of eLearning environments and the design of
collaboration scripts are two research areas that are acquiring a greater
attention within the Computer Supported Collaborative Learning (CSCL)
community. IMS Learning Design (IMS-LD) is the specification used to describe
instructional strategies. In this paper we analyse the suitability and lacks of
IMS-LD for modelling collaborative learning processes. Based on this result, we
propose a reference model inside the IMS specifications core and the use of a
graphical notation called CIAN (Collaborative Interactive Applications
Notation) as CSCL scripting language. Using these specifications of a high
level of abstraction and mappable to a computer-interpretable notation such as
IMS-LD, allows hiding the particularities of the standard to instructional
designers.

Summary: This paper proposes a methodological approach for Model Based User Interface
Development of Collaborative Applications. This proposal is based on the use of
several models for representing collaborative and interactive issues.
Therefore, several techniques and notations are used. We describe the
integration process of two notations: CIAN, which involves collaboration and
human-computer interaction aspects; and UML, which specifies groupware systems
functionality. In addition, we describe how this model is integrated into the
Software Engineering Process. Both integration processes are developed by using
software tools like CIAT and EPFC.

Summary: Within groupware systems, collaborative modelling systems play an important
role. They are useful and promising tools for many fields of application. One
of these fields in which collaborative modelling tools can be useful is the
design and systematic development of usable User Interfaces (UI) using task
models. In this paper, the use of a generic modelling groupware system,
SPACE-DESIGN, is proposed for task modelling using CTT, one of the most used
notations in this area. In order to evaluate the utility of the approach, a
comparative study with two groups of experienced users and a heuristic
evaluation using some well-known frameworks have been made. Results and
conclusions of the evaluation are discussed.

Summary: The development of mechatronic products requires the integration of
different technical disciplines by personnel who reside in separate locations,
a fact that is particularly evident for the case of virtual enterprises.
Concurrent engineering of these products can be enhanced significantly through
the use of sophisticated data management and visualization tools such as
Product Lifecycle Management (PLM). The key benefit of a PLM system is its
ability to facilitate the coordination of the activities among geographically
distributed team members. This paper describes models and procedures that were
developed and implemented during the selection and configuration of a PLM
environment for machine tool design and construction in a virtual enterprise.
The experiences from this case, particularly the bottlenecks and how they were
addressed are discussed in detail. Finally, recommendations for better
deployment of PLM for similar conditions are presented.

Summary: Reconfigurable machine tools (RMT) have emerged as a potential solution to
meet the demand for rapid adaptation in the next generation manufacturing
systems. While a significant amount of research in RMT design is available,
formal design methodologies are still under development. In previous work, a
modularity framework technique for the development of RMT modules was outlined.
The technique focused on module functionality and constructability. While in
general these characteristics are critical for the survival of any product,
specific characteristics of RMT were not easily addressed by the proposed
methodology. In particular, convertibility, in the form of upgradeability and
adaptability, was not addressed. This article presents an enhanced modularity
framework that takes into consideration the intended evolution lines of the
reconfigurable machine tool. The basic principles are outlined and applied to
the design of a machine tool for metal working. Recommendations for future
enhancements to the framework are made, in particular, the possibility of
developing a convertibility index to facilitate evaluation of candidate designs
is discussed.

capable of develop high customized products. In order to compete, companies
require adopting structured process to develop and improve their practices in
Integrated Product, Process and Facility Development (IPPFD). This research
project demonstrates how the methodological use of a Reference Model allows the
companies to create a Particular Model to set-up successful IPPFD Processes
focusing on specific issues of the company. One case study was implemented to
demonstrate how the Reference Model can be used in a company to develop a New
Product Development Program to redesign and improve its products.

Summary: Computer-assisted educational environments are an excellent complement to
the learning process. However, when domains are complex, the expected learning
support objectives may not be achieved. We are interested in the exploration,
study and application of new interactive technologies suitable for their use in
the classroom. We propose the use of Computer Supported Collaborative Learning
combined with Simulation and 3D representation for assisting in learning
processes. We believe in the potential of this synergy to support learning in a
case study: the teaching of Domotics, i.e., the design of automated control
facilities in buildings and housings.
