| Using Spatial Augmented Reality in Synchronous Collaborative Design | | BIBAK | Full-Text | 1-10 | |
| Samia Ben Rajeb; Pierre Leclercq | |||
| This article examines applications of Spatial Augmented Reality (SAR) in
architectural and engineering collaboration. These applications can be split
into four SAR configurations supported by an innovative software program
(SketSha) which enables remote sharing of graphic documents and annotations in
real time; remote expert consultation, collaborative design, project review and
group evaluation are all implemented in collaborative design training.
Analysis of how SAR affects instrumented training activities is qualitatively conducted on four axes: (1) the status of the object being collaboratively designed; (2) the status of the document as an intermediary object for collaboration; (3) the status of the participants in aiding collective intelligence to emerge and (4) the status of workspace as we question the "co-presence / remote" dichotomy in synchronous relations.

| Collaborative Responsive Façade Design Using Sensor and Actuator Network | | BIBAK | Full-Text | 11-18 | |
| Sun-Young Jang; Seongki Lee; Sung-Ah Kim | |||
| The building facade interacts with its neighboring environment as an active
element; therefore it is unreasonable to conceive the facade as merely a
dividing entity between the interior and the exterior. The envelope system of
smart building can dynamically improve dwelling conditions by intelligently
reacting to climate changes. This research proposes a collaborative responsive
building façade design method using sensor and actuator network. By
synchronizing both virtual and physical models, the design state of the change
or improve simultaneously. This study reflects the lighting level data among
the various environmental elements to design responsive façade
prototype. We utilized motion sensors to detect the movement of designer's
gestures for creating more intuitive design process. Keywords: Responsive Façade; Collaborative Design; Kinetics; Interactive Wall;

| Collaborative Design Process for Encouraging Sustainable Building Design: A Game Theory-Based Approach | | BIBAK | Full-Text | 19-26 | |
| YuMi Song; Seongki Lee; Yoon Choe; Sung-Ah Kim | |||
| Information permeated in a daily life through ambient urban media may have
positive effects on people's behavior and consciousness. This approach can be
adapted to enhance sustainable building design in an educational environment.
In this paper, information about sustainable building design is provided and
the visualized evaluation is fed back, as a way to encourage sustainable
building design. In addition, to maximize the effect of the interaction between
competition and cooperation among students, we have applied a game theory
approach called 'prisoner's dilemma'. Information visualization is effective to
change the focus of interests in the students' design and a game theory helps
produce a variety of design alternatives. The method can improve the design
capabilities and change the students' consciousness as well. Keywords: Design Process; Design Education; Game Theory; Collaboration; Protocol

| Preserving Non-verbal Features of Face-to-Face Communication for Remote Collaboration | | BIBAK | Full-Text | 27-34 | |
| Jörg Edelmann; Philipp Mock; Andreas Schilling; Peter Gerjets | |||
| Distributed working groups rely on collaboration systems that promote
working on a project cooperatively over a distance. However, conventional
systems for remote cooperative work do not transport important non-verbal cues
of face-to-face communication like eye-contact or gaze awareness that would be
available in co-located collaboration. Additionally, reference material and
annotation tools should be readily accessible for all users. The screen layout
should moreover create awareness for the transmitted video of remote
participants and reference material alike and allow users to easily follow both
at the same time. This paper describes how the presented system Face2Face meets
these requirements and thereby supports the collaborative design process.
Furthermore, the performance of the system is evaluated in order to validate
its practical applicability. Keywords: remote collaboration; telepresence; face-to-face; multi-touch; awareness | |||
| The Use of Media in Intercultural Dialogue "dialogo_dialog"! | | BIBAK | Full-Text | 35-42 | |
| Ursula Kirschner | |||
| The initiation of a cultural event provided the basis for this research
project: An intercultural artistic dialogue connected two almost deserted
railway stations in Germany and in Brazil. One band performed in the station
hall in Germany which was linked via live stream to the station in Brazil. In
this station at the same time one Brazilian band performed.
For this intercontinental event neither language nor translation was required, as other artistic means were used. The room, the music, the lighting and the presence of the people provided an atmosphere for interaction, which exceeded the level of communication that would have been achieved through language. The fast pace of technological progress is intertwined with the rapid development of global networks extending to the whole world. New interactive structures and relationships created a new dimension of intercultural communication, which seems essential for the organization and implementation of global processes. Exchange and communication are primarily based on mutual understanding. Keywords: live steaming; revitalization of old buildings; transcultural communication | |||

field trial of distributed collaboration in engineering. Keywords: distant collaboration; 3D models; video streaming | |||
| Monitor, Control and Process -- An Adaptive Platform for Ubiquitous Computing | | BIBAK | Full-Text | 47-50 | |
| Tiago Boldt Sousa; Angelo Martins | |||
| Monitor, control and process data on top of distributed networks has been a
trending topic in the past few years, with ubiquity being adjective to
computing and, gradually, the Internet of Things becoming a reality in home and
factory automation or Ambient Assisted Living (aal). Still, there is a general
lack of knowledge and best practices on how to build systems that integrate
devices and services from third-parties which connect dynamically with each
other. Recurring problems such as security, clustering, message passing,
deployment and other orchestration details also lack a standardized solution.
The authors describe a platform that simplifies the bootstrap and maintenance
of such complex systems, presenting its application in an aal scenario. Such
platform could orchestrate most distributed systems, possibly setting a pattern
for distributed ubiquitous computing. Keywords: Distributed Systems; Ubiquitous Computing; aal | |||

| Alexandru Senciuc; Caroline Lecourtois | |||
| Online technologies are already fully integrated into almost every domain of
activity. We want to better understand if and how these tools assist groups of
people in their architectural conception process. By looking at cooperation,
collaboration and coordination moments from the architecturological point of
view we hope to associate cognitive operations of conception to the use of
certain online tools. The purpose of this research is to build a theoretical
model of the collective architectural conception process in relation to the use
of basic online tools. Keywords: collective architectural conception; basic online tools; architecturology;

| Tablet-Based Synchronous Mobile Learning System | | BIBAK | Full-Text | 56-60 | |
| Jang Ho Lee | |||
| Since most of the existing smartphone-based learning systems are
asynchronous, smartphone-based synchronous learning systems became available
recently. However, the display of smartphone is not large enough for students
to recognize lecture slides with annotation, which can lead to the poor
learning experience. Thus, we propose a tablet-based synchronous mobile
learning system that allows users to watch the ongoing lecture video and
presentation slides with annotation as well as to send text feedback to an
instructor on a tablet in real time. Most of the students mentioned that they
felt more focused during the lecture with the presented tablet-based learning
system because the slide and annotation is easier to recognize and typing
questions is easier and quicker than smartphone-based learning system. Keywords: tablet; mobile learning; synchronous collaboration; distance learning;

| Designing and Evaluating Collaborative Learning Scenarios in Moodle LMS Courses | | BIBAK | Full-Text | 61-66 | |
| Leovy Echeverria; Ruth Cobos; Mario Morales | |||
| The main purpose of this paper is to present a service called Teaching
Assistant. The aim of the assistant is to facilitate the task and assessment
management in collaborative learning scenarios. This assistant intends to help
instructors to design and to evaluate collaborative learning tasks in this type
of scenarios. For the development of the Teaching Assistant we defined an
instructional model based on the Group Investigation method. The implementation
of the assistant is embedded into the Learning Management System Moodle.
Nowadays, a research study has been performing with students and instructors at
the Universidad Pontificia Bolivariana, UPB-Montería (Colombia). The
objective of the study is to identify the effect of the Teaching Assistant in
the design process of the collaborative learning scenarios scripted by the
instructors in Moodle. Specifically, how the assistant decreases the time used
in this process. Due to this improvement, the learning experiences can be
better. Keywords: Collaborative Learning Scenarios; Computer Supported Collaborative Learning

| The Social Media is a term used to define a wide range of network tools or
technologies, which deal with the social aspects of internet as a channel of
communication, collaboration and creative expression. This type of environments
has been used for educational practices in different areas, competing sometimes
with e-learning institutional environments, such as the Learning Management
Systems (LMS).
This paper proposes the extension of a specific LMS, Moodle, through Social Media services. This plugin provide the interaction and collaboration of all users. The main aim of the proposed approach is to enrich the existing educational process provided by this LMS. Keywords: e-Learning; Computer Supported Collaborative Learning (CSCL); Learning

| Efficient Usage of Collective Classification Algorithms for Collaborative Decision Making | | BIBAK | Full-Text | 73-80 | |
| Tomasz Kajdanowicz | |||
| Collective classification algorithms with underlying network structure of
related entities are a powerful modelling tool that can address collaborative
decision making problems. The paper presents the usage of collective
classification algorithms for classification problem in which unknown nodes are
assigned with classes based on the classes of known nodes. In such problem the
classification decision for particular node is inferred from collaborative
knowledge of nodes with known classes and underlying network connections. The
paper considers Iterative Classification (ICA) and Loopy Belief Propagation
(LBP) algorithms applied in various network configurations for collaborative
decision making. The experimental results revealed that greater number of
output classes decreases classification accuracy and LBP outperforms ICA for
dense network structures while it is worse for sparse networks. Keywords: Collaborative Decision Making; Collective Classification; Iterative

| User-Driven Data Preprocessing for Decision Support | | BIBAK | Full-Text | 81-84 | |
| Olivier Parisot; Pierrick Bruneau; Yoanne Didry; Thomas Tamisier | |||
| Decision trees are helpful decision support tools, due to their graphical
nature and the easiness to obtain them from data. Unfortunately, decision tree
size tends to grow according to the complexity of the learning data, which may
be problematic in real world settings. This paper proposes an original solution
to reduce the size of decision trees by taking user preferences into account.
More specifically, we present a user-driven algorithm that automatically
transforms data in order to construct simpler decision tree. A prototype has
been implemented, and the benefits are shown on several UCI datasets. Keywords: decision tree; data preprocessing; user-driven | |||
| A Cooperative Decision Making Algorithm for Wireless Location Systems Using Interlinking Data | | BIBAK | Full-Text | 85-92 | |
| Miguel Garcia; Diana Bri; Jesus Tomas; Jaime Lloret | |||
| Nowadays, several wireless location systems have been developed in the
research world. The goal of these systems has always been to find as greatest
accuracy as possible. But, if every node takes data from the environment, we
could gather a lot of information, which may help us to know what is happening
around our network. In order to obtain the correct conclusion, we have
developed an algorithm based on interlinking data. These data come from several
nodes, and each node can give us one or several parameters. Our algorithm deals
these data cooperatively in order to find the connection between them and
provide the environmental behavior. This algorithm is based on statistical
methods due to the fact that it involves an observational experiment. Finally,
our cooperative decision making algorithm is tested on a wireless location
system. The results show that this algorithm works properly and we are able to
know what is happening around our wireless location system when we use it. Keywords: cooperative decision; interlinking data; wireless location system; wireless

| Product Lifecycle Management Model for New Technology Based Enterprises | | BIBAK | Full-Text | 93-100 | |
| David A. Medina-Barbosa; Héctor R. Siller | |||
| This research is focused in a Product Lifecycle Management (PLM) strategy
for New Technology Based Enterprises (NTBE) for solving difficulties for
integrating the product requirements and for improving the collaboration with
the external contributors that occur in almost all the PLM stages, considering
the limited resources of a Small Enterprise. In this work, we analyze a case
study of the collaboration between a New Technology Based Enterprise, its
Suppliers and Customers and we present a Product Requirement Representation
considering the International Standard ISO 10303-0239. After the analysis and
with the presented product representation, we propose a PLM Reference Model and
an implementation of Open Source Software as a low cost solution for enabling
PLM in this kind of business collaborative environment. Keywords: New Technology Based Enterprise; Product Lifecycle Management; Collaborative

| Engaging End-Users in the Collaborative Development of Domain-Specific Modelling Languages | | BIBAK | Full-Text | 101-110 | |
| Javier Luis Cánovas Izquierdo; Jordi Cabot; Jesús J. López-Fernández; Jesús Sánchez Cuadrado; Esther Guerra; Juan de Lara | |||
| Domain-Specific Modelling Languages (DSMLs) are high-level languages
specially designed to perform tasks in a particular domain. When developing
DSMLs, the participation of end-users is normally limited to providing domain
knowledge and testing the resulting language prototypes. Language developers,
which are perhaps not domain experts, are therefore in control of the language
development and evolution. This may cause misinterpretations which hamper the
development process and the quality of the DSML. Thus, it would be beneficial
to promote a more active participation of end-users in the development process
of DSMLs. While current DSML workbenches are mono-user and designed for
technical experts, we present a process and tool support for the
example-driven, collaborative construction of DSMLs in order to engage
end-users in the creation of their own languages. Keywords: Model-Driven Engineering; Language Engineering; Domain-Specific Languages;

| Conflict Coordination Based on the Transformation Bridge for Collaborative Product Performance Optimization | | BIBAK | Full-Text | 111-119 | |
| Yanwei Zhao; Huanhuan Hong; Huan Wang; Weigang Chen; Hongwei Wang; Jing Jie | |||
| To quickly coordinate conflicts in product performance design, a
transformation bridge method was proposed. Specifically, the design problems of
performance conflicts were analyzed in terms of the quantification and
collaboration. Based on the analysis, the mathematical models for conflict
resolution and correlation function were developed. Thus the relationship
between performance and design variables could be identified, and then used for
searching similar cases from a repository. In addition, a core solution was
developed by identifying the correlation among performance, combining the
collaborative resolution method and case-based reasoning. The transformation
bridge method was leveraging the extensibility of the basic-elements.
Furthermore, the method for obtaining revised solutions was developed based on
extension theory in particular the transformation operator and the cyclic
transformation based on performance constraints, as the core of the approach to
product performance optimization. The viability is evaluated in a case of screw
air compressor design. Keywords: cooperative design; case based-reasoning; extension theory; conflict

| Towards a Performability Analysis for Environmental Sensor Networks | | BIBAK | Full-Text | 120-127 | |
| Sebastià Galmés | |||
| Wireless sensor and actor networks constitute one of the supporting
technologies for cooperative applications. Particularly, in the case of
environmental monitoring systems, ambient conditions can be conveniently
modified by means of the so-called actuators (actors), which are driven by
commands issued by a decision-making process on the basis of the information
gathered by sensor nodes. In this context, sensor nodes are typically deployed
at strategic locations on the basis of application requirements. These
locations may be far apart from each other, leading to unfeasible or highly
energy-consuming transmission distances. This paper provides an assessment of
the impact of relay node insertion on performance and reliability. Keywords: Sensor network; data-gathering tree; TDMA (Time-Division Multiple Access);

| Quad-copters, sometimes called quad-rotors or quad-rotor helicopters, are
currently a very popular platform for robotics research, primarily due to their
properties, such as small size and mechanical simplicity. Coordination in
multi-robot systems is one of the open issues of swarm robotics. Space
exploration and mapping are crucial abilities of mobile robots for the
intelligent autonomous systems. This paper proposes a solution for space
exploration and surveillance based on several biologically inspired methods and
algorithms. The best form to represent the results form research simulations is
the 3D visualization. The paper also describes the developed tool for
visualization of more than one quad-copters as mobile agents during simulation. Keywords: Quad-copter; cooperative visualization; visualization tool; swarm

| Cooperative Design and Communities of Practice | | BIBAK | Full-Text | 141-152 | |
| Chris Johnson; Karen Bull; Jane Osmond | |||
| The focus of teaching and learning within Coventry University's Automotive
and Industrial Design course is to equip students with a passport to enter
their professional community of practice [1] [2].
One of the core competencies contained within this passport is co-operative working and teamwork -- seen as a fundamental aspect of the creative design process, from concept to production -- and this is seen as a threshold concept within the course. Therefore, to provide designers for industry it is imperative the discipline of co-operative working is part of the learning process as designers will be expected to interact with a wide range of disciplines 'such as engineering, business, sociology, and psychology, among others'. [3]. And, in today's global world, designers will often be expected to do so across geographical boundaries. This paper presents four case studies, underpinned by feedback and work outputs designed to foster co-operative learning, from each year of the automotive and industrial design course.

| Optimization of Engineering Design Cycles in Enterprise Integration | | BIBAK | Full-Text | 153-156 | |
| Dariusz Choinski; Piotr Skupin; Ernest Szajna | |||
| The paper presents the concept of project life cycle optimization, which is
based on the formalization of domain knowledge and decomposition of the
controlled system into subsystems. The formalization of knowledge concerns each
of the individual subsystems by describing its states and functions. Such an
approach can greatly reduce costs and time, which is needed for multiple
iterations during the project life cycle. This is because the formalization of
knowledge simplifies modifications of the control system software and
architecture, which means that there is no need to commence the designing
process again. Moreover, owing to the presented approach, creation of ontology
and more advanced control systems (e.g. multiagent based algorithms) are
significantly shortened and simplified. The presented solution is currently
being implemented in the designing process of a real micro-grid. Keywords: Collaborative design; Project life cycle; Concurrent engineering | |||

| The paper presents the requirements and challenges to collaborative design
related to the design of vessels for offshore operations in the Arctic area. We
look into the design process of offshore service vessels in environments
characterized by high volatility and complexity. Due to increased complexity as
to functionality, the number of stakeholders and uncertainty as to
environmental aspects more information from different sources have to be
included, also encompassing long trial periods with user feedback. This has
implications for the construction processes and the open interplay with

| Collaborative 4D/nD Construction Simulation: What Is It? | | BIBAK | Full-Text | 161-168 | |
| Conrad Boton; Sylvain Kubicki; Gilles Halin | |||
| Planning is crucial in the success of construction projects and 4D/nD
simulation is an innovative approach to improve it. Because construction
planning is mainly a collaborative activity, the collaborative use of 4D/nD
simulation is growing in the Architecture, Engineering and Construction (AEC),
following the implementation of Building Information Modeling (BIM) work
processes. Multiple scientific research works have been devoted to
collaborative 4D/nD simulation. Major software editors in the industry are also
proposing solutions to develop it. But many challenges remain such as adapting
visualization or optimizing collaboration processes. To be able to address
these challenges, it is important firstly to conceptualize the notion of
collaborative 4D/nD construction simulation. This article is based on an
understanding of collective activity in the AEC industry, and theoretical
elements from Simulation and CSCW scientific fields. It provides a generic
definition and identifies the key components to consider in the improvement of
collaborative 4D/nD simulation tools. Keywords: CSCW; 4D simulation; nD simulation; collaborative simulation; Architecture;

| Dino Borri; Domenico Camarda; Irene Pluchinotta | |||
| The phenomenon of Urban heat islands (UHI) is most pronounced in areas with
high urbanization and complex phenomena, in which the domains of interaction
between humans and the environment are not standardized. In this context, an
approach fairly attentive to agents' (particularly human) behaviors represents
an interesting research perspective. The paper works on analyses carried out in
a case-study of public condo housing owned by the Institute of social housing
(IACP) in Bari (Italy), starting from a knowledge base collected through
focus-group experimental sessions. Fuzzy cognitive mapping (FCM) is
particularly dealt with, and a model based on FCMapper® tool allows the use
of local knowledge of stakeholders' analysis for ecological modelling and
environmental management in a bottom-up-decision-making process. The paper
follows and completes a previous work presented and discussed in CDVE 2011. Keywords: Urban microclimate planning; Decision support system; Multiple agents; Fuzzy

state-of-the-art of the presented problems is presented and the already
completed parts of the framework. The described work-in-progress concentrates
on industrial connectibility, downtimeless dynamic reconfiguration and conflict
resolution. The described project is promising due to the increasing role of
the IEC 61499 standard in the industrial practice and because of the lack of
similar educational solutions. Keywords: collaborative learning; control algorithms; IEC 61499; multiuser software | |||
| Practice and Usage-Oriented Service Adaptation: An Integrated Design Method for Collaborative Work in Construction Projects | | BIBAK | Full-Text | 181-188 | |
| Daniel Zignale; Sylvain Kubicki; Gilles Halin | |||
| Practitioners of the construction sector require improved Information
Technology (IT) Services to support their collaborative work. In usual service
design processes, business experts gather requirements and collaborate with
designers (e.g. Software Engineers or HCI experts) through modeling phases to
develop adapted solutions. Our main hypothesis is that improving modeling and
mapping of these different perspectives will enhance such service's design
processes. Based on the analysis of parallel research fields, this paper
addresses this issue, and proposes a method to adapt IT-supported services to
business practices. This method is based on a structured approach aiming at (1)
identifying Collective Practices, (2) focusing on actors' Individual Practices
and Operations, (3) distinguishing different technology-related Usages and
finally (4) selecting or designing adapted IT services relying on previous
analysis. An example based on sustainable project practices illustrates the
approach. Keywords: Computer-Supported Collaborative Work; Architecture Engineering and

| Building Information Modelling (BIM)-Supported Cooperative Design in Sustainable Renovation Projects | | BIBAK | Full-Text | 205-212 | |
| Danilo Di Mascio; Xiangyu Wang | |||
| This paper presents and demonstrates the main benefits and limitations of
the BIM technology in sustainable renovation projects. The built environment is
acknowledged as a value both as material and cultural resource to be preserved.
The set of buildings that constitutes the built environment represents a
valuable deposit of meanings and knowledge. A proper conservation of the built
environment is expressed by a sustainable use of materials and
territories/lands that have to be preserved for the future generations.
Furthermore, undertaking a sustainable way to renovate the buildings means to
improve the quality of life and health of people/inhabitants. There are many
differences between the design of new buildings from scratch and the renovation
of existing buildings. In the latter case, the designer has to tackle the
difficulties that arise from the real buildings, represented by a set of
constraints (i.e.: walls, beams, spaces, etc.). Digital tools, and in
particular Building Information Modeling (BIM), make manageable and improve the
design, organization and construction of renovation projects. The benefits
using BIM during cooperative design for sustainable renovation projects affect
the three dimensions of sustainability (environmental, economical and social)
but there are also limitations that delay its diffusion in this field within
the AEC sector. Keywords: BIM; sustainability; renovation; digital reconstruction; integrated design | |||

| The purpose of this research is to propose an interactive decision making
environment for design optimization of Climate Adaptive Building Shells (CABS).
As the success of the CABS is highly dependent on the decision-making between
design process and building performance simulation, we propose the effective
design process and the method of information visualization. To reach the goal,
first we optimize the motion state of kinetic facade using both the generative
parametric design and building environmental performance simulation. Second we
represent information for easy decision-making. This research can enhance the
advantage of the CABS in terms of building life-cycle. Keywords: Climate Adaptive Building Shell (CABS); Building environmental performance

| Building Information Modeling (BIM) is a technology that can be applied in
numerous fields, such as construction management, facility operation and
structure and MEP design. BIM enables the representations of digital building
information at any construction stages. However, very few instances have been
investigated regarding how to apply BIM to effectively facilitate the
collaborative work such as planning, design, and information sharing. This
paper introduces a collaborative mobile system which integrates a context-aware
Augmented Reality (AR) visualization with BIM. The BIM plus AR system
visualizes the as-planned data onto the as-built environment. The applications
based on this system give the possibility of using this system to address some
of the real problems and issues from Australian Liquefied Natural Gas (LNG)

tendency of committing error in assembly, low efficiency of communication and
problem solving, etc. Keywords: BIM; AR visualization; collaborative work; LNG | |||

| Dariusz Choinski; Radoslaw Dymek; Michal Senik; Piotr Skupin; Zbigniew Szkaradnik | |||
| The paper presents studies on the improvement and development of cooperation
methods for cost optimization in power supply systems using polygeneration
technology. A support for cooperating operators, which are responsible for
maintenance and supervision of the power supply system, is realized by means of
appropriately chosen mathematical models and ontology based knowledge sharing
and management idea. Ontology based approach enables various pieces of the
integrated system to cooperate more autonomously by optimizing and reducing
their need for communication. In effect, the system operators are provided with
strictly necessary information on: the functioning of devices, the number of
operating states, available control strategies and the actual and expected
prices of electricity. Based on this information, the system operators are able
to take appropriate decisions leading to cost reduction and to maintain
reliability of the power supply system at the desired level for various
operating conditions. Keywords: knowledge management based cooperation; MAS; energy cost optimization | |||
