| Attention-Based Management of Information Flows in Synchronous Electronic Brainstorming | | BIBA | Full-Text | 1-16 | |
| Antonio Ferreira; Valeria Herskovic; Pedro Antunes | |||
| In this paper we argue for buffering group awareness information to mitigate information overload and help users keep up with the group. We propose an attentive groupware device, called the opportunity seeker, that leverages the natural alternation between a user doing individual work and attending to the group to automatically manage the timing and quantity of information to be delivered based upon each user's state of attention. We explain how this device can be applied to synchronous electronic brainstorming and present results from a laboratory experiment, which indicate that groups produced 9.6% more ideas when compared to the immediate broadcast of ideas. In addition, a user-level post-hoc analysis suggests that information overload was attenuated with the opportunity seeker as users had 7.5 seconds of extra uninterrupted time to think about and type an idea, which they began to write 6.4 seconds sooner, and completed in 4.2 seconds less time. | |||
| Implementing a System for Collaborative Search of Local Services | | BIBAK | Full-Text | 17-24 | |
| Tiago Conde; Luis Marcelino; Benjamim Fonseca | |||
| The internet in the last few years has changed the way people interact with
each other. In the past, users were just passive actors, consuming the
information available on the web. Nowadays, their behavior is the opposite.
With the so-called web 2.0, internet users became active agents and are now
responsible for the creation of the content in web sites like MySpace,
Wikipedia, YouTube, Yahoo! Answers and many more. Likewise, the way people buy
a product or service has changed considerably. Thousands of online communities
have been created on the internet, where users can share opinions and ideas
about an electronic device, a medical service or a restaurant. An increasing
number of consumers use this kind of online communities as information source
before buying a product or service. This article describes a web system with
the goal of creating an online community, where users could share their
knowledge about local services, writing reviews and answering questions made by
other members of the community regarding those services. The system will
provide means for synchronous and asynchronous communication between users so
that they can share their knowledge more easily. Keywords: groupware; web 2.0; local services; social communities | |||
| Shared Resource Availability within Ubiquitous Collaboration Environments | | BIBAK | Full-Text | 25-40 | |
| Kimberly García; Sonia Mendoza; Gustavo Olague; Dominique Decouchant; José Rodríguez | |||
| Most research works in ubiquitous computing remain in the domain of
mono-user systems, which make assumptions such as: "nobody interferes, observes
and hurries up". In addition, these systems ignore third-part contributions and
do not encourage consensus achievement. This paper proposes a system for
managing availability of distributed resources in ubiquitous cooperative
environments. Particularly, the proposed system allows collaborators to publish
resources that are intended to be shared with others collaborators and to
subscribe to allowed resources depending on their interest in accessing or
using them. Resource availability is determined according to several
parameters: technical characteristics, roles, usage restrictions, and
dependencies with other resources in terms of ownership, presence, location,
and even availability. To permit or deny access to context-aware information,
we develop a face recognition system, which is able to dynamically identify
collaborators and to automatically locate them within the cooperative
environment. Keywords: Availability of distributed resources; perception; ubiquitous cooperative
environments; human face recognition; automatic user localization | |||
| Context Awareness and Uncertainty in Collocated Collaborative Systems | | BIBA | Full-Text | 41-56 | |
| Roc Messeguer; Pedro Damián-Reyes; Jesús Favela; Leandro Navarro | |||
| Context awareness is a necessary feature for mobile collocated collaborative learning. In this paper we describe how requirements for context-aware cooperative learning activities are derived from the jigsaw technique augmented with the use of mobile devices, applications to support the activities of groups, and tools to provide context-awareness to detect group formation. The emergence of groups is detected based on the location of the students within the classroom, but this information has to be careful filtered to evaluate the degree of uncertainty and protect from erroneous estimations. A three-phase strategy to manage uncertainty by identifying possible sources of uncertainty, representing uncertain information, and determining how to proceed under the presence of uncertainty is used for this propose. These requirements are validated and confirmed in experiments with students working together in the classroom, measuring neutral or positive effects on learning and the usefulness of introducing mobile devices, group support applications, and context awareness. The ratio of unwanted interruptions to users made by the system is used to evaluate the utility of the system. Results show that by managing uncertainty, location estimation becomes more reliable, thus increasing the usefulness of the learning application. | |||
| Information Needs for Meeting Facilitation | | BIBAK | Full-Text | 57-64 | |
| Adriana Santarosa Vivacqua; Leandro Carreira Marques; Marcos S. Ferreira; Jano Moreira de Souza | |||
| In many group work settings, meetings take up a reasonable amount of time
and often do not achieve satisfactory outcomes. One of the techniques that has
been introduced to ensure meetings run smoothly and reach their goals places an
individual in the role of meeting facilitator. Facilitation involves putting
together the meeting agenda, designing meeting dynamics and overseeing the
meeting at run time, to ensure goals are met. This may involve intervening or
adjusting meeting structure to produce desired results. Thus, a facilitator
should be able to act according to perceived group dynamics or problems. In
this paper, we investigate information needs during facilitation activities.
Our goal is to be able to construct systems that provide information to the
facilitator so he or she can decide when to act and what to do. Keywords: meeting facilitation; information provision | |||
| Risk Assessment in Healthcare Collaborative Settings: A Case Study Using SHELL | | BIBAK | Full-Text | 65-73 | |
| Pedro Antunes; Rogério Bandeira; Luís Carriço; Gustavo Zurita; Nelson Baloian; Rodrigo Vogt | |||
| This paper describes a case study addressing risk assessment in a hospital
unit. The objective was to analyse the impact on collaborative work after the
unit changed their installations. The study adopted the SHELL model. A tool
aiming to support the inquiring activities was also developed. The outcomes of
this research show the model is adequate to analyze the complex issues raised
by healthcare collaborative settings. The paper also provides preliminary
results from the tool use. Keywords: SHELL; Risk Assessment; Collaborative Settings; Hospitals | |||
| Persuasive Virtual Communities to Promote a Healthy Lifestyle among Patients with Chronic Diseases | | BIBAK | Full-Text | 74-82 | |
| Eduardo Gasca; Jesús Favela; Monica Tentori | |||
| The World Health Organization has declared obesity a world-wide epidemic.
People with obesity have a higher risk to attain chronic diseases, high risk of
premature death and a reduced quality of life. Recent studies have shown that
persuasive technologies and virtual communities can promote healthy lifestyles.
In this article, we describe the development of a Persuasive Ecosystem aimed at
promoting a healthy lifestyle in patients with a chronic disease that
participate in a support group. The study was inspired in the results of a case
study conducted in a hospital responsible for running this group. The results
of a preliminary evaluation show an increased engagement of the patients with
the program due to the use of the system. Keywords: Persuasive Ecosystem; Virtual Community; pHealthNet | |||
| Supporting the Social Practices of Distributed Pair Programming | | BIBA | Full-Text | 83-98 | |
| Till Schümmer; Stephan Lukosch | |||
| When considering the principles for eXtreme Programming, distributed eXtreme Programming, especially distributed pair programming, is a paradox predetermined to failure. However, global software development as well as the outsourcing of software development are integral parts of software projects. Hence, the support for distributed pair programming is still a challenging field for tool developers so that failure for distributed pair programming becomes less mandatory. In this paper, we analyze the social interaction in distributed pair programming and investigate how current technology supports this interaction. We present XPairtise, a plug-in for Eclipse that allows instant pair programming in distributed development teams. In addition, we report on experiences and findings when using XPairtise in a distributed software development setting. | |||
| Using Second Life in Programming's Communities of Practice | | BIBAK | Full-Text | 99-106 | |
| Micaela Esteves; Ricardo Antunes; Benjamim Fonseca; Leonel Morgado; Paulo Martins | |||
| This paper presents a novel approach to teaching and learning computer
programming, using the three-dimensional virtual world Second Life® to
develop a programming community of practice. Our students have developed their
programming projects as part of this community as an alternative way of
learning. The learning of programming is a difficult process, with many
students experiencing difficulties which result in high levels of failure in
introductory programming courses. In this paper, we describe and analyse how
this approach spurred students' motivation and interest in learning
programming. We also present observations on the difficulties felt by both
students and teachers in the development of projects and activities, and
discuss the approaches taken to overcome those difficulties. Keywords: Communities of practice; Collaboration; Programming learning; Virtual
worlds; Second Life | |||
| Integrating Collaborative Program Development and Debugging within a Virtual Environment | | BIBAK | Full-Text | 107-120 | |
| Hani Bani-Salameh; Clinton Jeffery; Ziad Al-Sharif; Iyad Abu Doush | |||
| A collaborative integrated development environment enables developers to
share programming-related tasks. This paper presents the design and
implementation of a collaborative IDE named ICI (Idaho Collaborative IDE). ICI
enables developers in different locations to collaborate on a variety of
software development activities in real-time. It supports software development
in C, C++, Java, and Unicon. ICI combines a synchronous collaborative program
editor and a real-time collaborative debugger within a 3D multi-user virtual
environment. ICI reduces cognitive context switches between tools inside the
IDE and between IDE tasks and virtual environment activities, allowing
developers to share, in real-time, the process of editing, compiling, running,
and debugging of their software projects. Keywords: collaborative environment; debugger; run-time debugging; Integrated

| Evaluating a Mobile Emergency Response System | | BIBA | Full-Text | 121-134 | |
| Cláudio Sapateiro; Pedro Antunes; Gustavo Zurita; Rodrigo Vogt; Nelson Baloian | |||
| Existing information systems often lack support to crisis and emergency situations. In such scenarios, the involved actors often engage in ad hoc collaborations necessary to understand and respond to the emerging events. We propose a collaboration model and a prototype aiming to improve the consistency and effectiveness of emergent work activities. Our approach defends the requirement to construct shared situation awareness (SA). To support SA, we developed a collaborative artifact named situation matrixes (SM), which relates different situation dimensions (SD) of the crisis/emergency scenario. A method was also developed to construct and evaluate concrete SM and SD. This method was applied in two organizations' IT service desk teams, which often have to deal with emergency situations. The target organizations found our approach very relevant in organizing their response to emergencies. | |||
| Maturity Levels of Information Technologies in Emergency Response Organizations | | BIBAK | Full-Text | 135-150 | |
| Raphael S. Santos; Marcos R. S. Borges; José Orlando Gomes; José Hilario Canós | |||
| In emergency response organizations with very limited resources, information
technologies are not adequately explored. In such organizations, the simple
adoption of new information technologies is not productive, as their efficient
use depends on many other interrelated technologies. This work describes a
model to help understanding these interrelationships. The model allows the
cooperative evaluation of an organization through different perspectives. The
model also helps the performing of the evaluation from different perspectives,
making it suitable to collaborative evaluation. Using the model, an
organization can measure its maturity level and guide the investment in
emergency response capabilities. The information technology dimension of the
model has been applied to the firefight organization in Brazil. Keywords: Emergency organizations; collaborative assessment; maturity models | |||

| Frank Fuchs-Kittowski; Daniel Faust | |||
| In this paper the semantic architecture tool (SemAT) for collaborative EA development is presented. This includes the concept of a semantic wiki-like collaboration tool for collaborative EA management and an EA ontology as a formal representation of the EA. In addition, the prototypical implementation of the semantic collaboration environment is described. Finally, the benefits of the approach are discussed. | |||
| Towards a Virtual Environment for Regulated Interaction Using the Social Theatres Model | | BIBAK | Full-Text | 164-170 | |
| Ana Guerra; Hugo Paredes; Benjamim Fonseca; Fernando Mário Martins | |||
| The last decade brought about several virtual communities spread all over
the world composed of thousands of people with different ages and social,
cultural and physical characteristics. These communities enable users to
communicate and share information, often with the aim of achieving a common
goal. Due to the vast diversity of users there's often a need to control the
activities that occur inside the virtual environment to avoid inappropriate
behaviors. However, this control can cause a feeling of digital surveillance,
but an appropriate design of the interface can help minimize its impact,
becoming an important success factor for the community. For this purpose we
analyzed a selection of virtual environments, conducted a survey on users'
preferences and analyzed the corresponding results. From these activities we
defined a set of requirements to build a 3D interface for a regulated virtual
environment. Keywords: Interaction Environments; Social Interaction; User interfaces; Virtual

| Addressing Co-text Loss with Multiple Visualizations for Chat Messages | | BIBAK | Full-Text | 171-182 | |
| Torsten Holmer; Stephan Lukosch; Verena Kunz | |||
| In this article we address the problem of co-text-loss in chat
communication, identify requirements for a solution, discuss related work and
present a new approach for addressing co-text loss in text-based chats. We
report about first experiences with our solution and give an outlook on future
work directions. The core idea of our solution MuViChat (multiple-visualization
chat) is to support multiple visualizations of referenced chat transcripts in
which users can choose their preferred view. By enabling the recording and
replaying of chat discussions and an extensible modular architecture we are
supporting evaluation and further integration of advanced visualization
concepts. Keywords: chat tool; multiple visualizations; threading; chat transcript | |||
| Modifiers for Quality Assurance in Group Facilitation | | BIBAK | Full-Text | 183-195 | |
| Gwendolyn L. Kolfschoten; Paul Grünbacher; Robert O. Briggs | |||
| One of the key tasks of a facilitator is to assure the quality of the
knowledge outcome created in the collaborative effort. To manage the quality of
the knowledge generated facilitators need to follow along in the communication,
and to judge the quality of contributions, decisions and consensus. When
facilitators or group members detect quality deficiencies, facilitators have
the difficult task of making interventions to support the group in improving
the quality of their output, without interrupting the flow of the process. In
this paper we will present a framework for quality assessment and a toolbox
with flexible interventions that can be added to the process design on the fly,
as soon as quality deficiencies are detected. The toolbox exists of a set of
conditional adjustment interventions, which can be used to enhance the selected
facilitation techniques to guard for quality. Keywords: Facilitation; Quality Assurance; ThinkLets; Collaboration Engineering;

| Linking to Several Messages for Convergence: A Case Study in the AulaNet Forum | | BIBAK | Full-Text | 196-203 | |
| Mariano Gomes Pimentel; Hugo Fuks; Carlos José Pereira de Lucena | |||
| In this article, a piece of research on the development and use of a
discussion forum is presented. In an online course, it was identified that one
of the problems of the educational use of discussion forums is the high number
of messages that go unanswered. To attenuate this problem a convergence
mechanism was elaborated: links to messages beyond the replied one. In the case
study conducted in two course editions, it was verified that the use of links
decreased the number of unanswered messages. Keywords: LMS; Discussion forum; convergence; links | |||
| Understanding Methodological Differences to Study Convergence in Group Support System Sessions | | BIBAK | Full-Text | 204-216 | |
| Alanah J. Davis; Victoria Badura; Gert-Jan de Vreede | |||
| While previous research has studied the process of group divergence
extensively, little studies have been published regarding the process of group
convergence. Therefore, this research answers a call for more research on group
convergence to establish a better understanding of this critical group process.
The goal of this study is to answer a methodological question: Does the idea
set that a group processes during a convergence activity supported with a Group
Support System have to be pre-defined or should it be generated by the group
itself? The results of our lab experiment suggest that the results of the
convergence process are not significantly affected by whether or not
participants use pre-defined ideas or generate their own. This finding has
implications for experimental design in collaboration research and participant
selection and session design within organizations. Keywords: Convergence; divergence; brainstorming; thinkLets; collaboration

| Repeatable Collaboration Processes for Mature Organizational Policy Making | | BIBA | Full-Text | 217-232 | |
| Josephine Nabukenya; Patrick van Bommel; Henderik Alex Proper | |||
| Organizational policy making processes are complex processes in which many
people are involved. Very often the results of these processes are not what the
different stakeholders intended. Since policies play a major role in key
decision making concerning the future of organizations, our research aims at
improving the policies on the basis of collaboration.
In order to achieve this goal, we apply the practice of collaboration engineering to the field of organizational policy making. We use the thinklet as a basic building block for facilitating intervention to create a repeatable pattern of collaboration among people working together towards achieving a goal. Our case studies show that policy making processes do need collaboration support indeed and that the resulting policies can be expected to improve. | |||

| Luís Carriço; Luís Duarte; António Broega; Diogo Reis | |||
| This paper presents an analysis tool for comparative and collaborative
evaluation of mobile artefact usage. Three scenarios were envisioned for the
comparative dimension covering both multiple user performance analysis and
single-user evolution analysis through three different settings: result
browsing, interaction replay and online monitoring. The collaborative dimension
is detailed according to two settings: existence of a public display and the
use of shared spaces to exchange information between analysts. A couple of
analysis sessions were performed by end-users under group psychotherapy and
educational domains to assess how the tool fits in such scenarios. Keywords: Groupware; User Performance & Monitoring; Mobile Devices | |||
| Coordination Patterns to Support Mobile Collaboration | | BIBAK | Full-Text | 248-265 | |
| H. Andrés Neyem; Sergio F. Ochoa; José A. Pino | |||
| The increasing popularity of portable devices and advances in wireless
communication technologies push the development of mobile groupware
applications. Mobile applications are challenging for software designers
because the use of centralized components is not recommended, the communication
service cannot be ensured and the software must run on computer devices with
little hardware resources. Frequently, data and services interoperability is
also required for collaborators. A design patterns system is presented as a way
to deal with these modeling requirements; it is intended to help modeling the
coordination services required to support mobile collaboration. These patterns
serve as educational and communicative media for developers, students or
researchers on how to design services for mobile collaborative applications.
They also foster the reuse of proven solutions. Keywords: Coordination patterns; groupware mobile applications; design guidelines;

| LeadFlow4LD: Learning and Data Flow Composition-Based Solution for Learning Design in CSCL | | BIBAK | Full-Text | 266-280 | |
| Luis Palomino Ramírez; Miguel L. Bote-Lorenzo; Juan I. Asensio-Pérez; Yannis A. Dimitriadis | |||
| IMS-LD is the de facto standard for learning design (LD) specification which
typically comprises an activity flow and a data flow. Nevertheless, the
specification of the data flow between tools is an open issue in IMS-LD,
especially in collaborative learning. In such case, handling shared data
derived from individual and collaborative tools is error-prone for learners who
suffer an extra cognitive load. Additionally, problems in the collaborative
data flow specification affect the reusability of the whole learning design. In
this paper, we present LeadFlow4LD, a solution of specification and enactment
for LD in CSCL in order to address the aforementioned issues in an
interoperable and standard way. Such a solution is based on approaches for the
composition of the activity flow specified in IMS-LD and the data flow
specified in a standard workflow language, such as BPEL. An architecture and a
prototype for validating the propose solution through a case study based on a
significant CSCL situation are also presented. Keywords: Data Flow; Learning Design; Workflow; CSCL; IMS-LD | |||
| A Version Control System as a Tool and Methodology to Foster Children's Collaboration in Spatial Configuration Decision Tasks | | BIBAK | Full-Text | 281-288 | |
| Filipe Santos; Benjamim Fonseca; Leonel Morgado; Paulo Martins | |||
| Nowadays a growing number of research and projects emphasize a culture of
childhood that sees the child as an active participant in social life and, in
particular, in the planning and decision processes of the spaces where they
live most of their time. Under these projects children are asked to have a
direct role on the configuration of several spaces, such as public and school
playgrounds. This paper refers to a work in progress where a version control
system for a multiuser virtual world is being developed to address some of the
challenges that this kind of task and participants bring. Particularly this
tool is being designed and prototyped to foster children's involvement in
primary school activities where a class participation and consensus are
requested on the several school spatial configurations. Keywords: Virtual Worlds; Children; Groupware Development Frameworks; Workflow

| Facilitating Audio-Based Collaborative Storytelling for Informal Knowledge Management | | BIBA | Full-Text | 289-304 | |
| Stephan Lukosch; Michael Klebl; Tanja Buttler | |||
| The increased demand for audio books and the rise of podcasting indicate a comeback of listening. On this basis, audio-based collaborative storytelling functionalises the act of telling stories in groups. In this paper we identify the requirements for informal knowledge management by means of audio-based collaborative storytelling. After reviewing the state of the art, we present our solution which addresses these requirements and supports a process for audio-based collaborative storytelling. Our solution consists of a storytelling client application which supports nomadic work as well as a web portal which aims at building a storytelling community. We present the storytelling client application and the web portal along our process for of collecting, structuring, linking and using audio clips, and finish with a report on first experiences and an outlook on future advancements. | |||
| Toward a Taxonomy of Groupware Technologies | | BIBAK | Full-Text | 305-317 | |
| Daniel D. Mittleman; Robert O. Briggs; John D. Murphy; Alanah J. Davis | |||
| The rise of the global marketplace and the advancing of the World Wide Web
have given impetus to rapid advances in groupware. Hundreds of products now
exist in the groupware marketplace, and more appear monthly. To ease the
cognitive load of understanding what groupware technologies are, what
capabilities they afford, and what can be done with them, we analyzed hundreds
of computer-based collaboration-support products and distilled their attributes
into two complementary schemas -- a classification scheme and a comparison
scheme. The classification scheme provides a way to organize the many products
from the rapidly expanding groupware arena into a small set of relatively
stable categories. The comparison scheme provides the means to compare and
differentiate collaboration technologies within and across categories. Taken
together, the classification and comparison schemas provide a basis for making
sense of collaboration technologies and their potential benefits to the
collaboration community. Keywords: collaboration technology; computer-based collaboration-support products | |||
| PaperFlow: A Platform for Cooperative Editing of Scientific Publications | | BIBAK | Full-Text | 318-323 | |
| Guilherme Saraiva; Orlando Carvalho; Benjamim Fonseca; Hugo Paredes | |||
| The production of scientific publications requires usually the participation
of several authors that contribute to the final result according to their role
in the work being described. Nevertheless, this is obviously a cooperative
activity and requires the simultaneous presence of the collaborators or the
exchange of documents and annotations through email. Cooperative editors
introduced a further step in the cooperation, but the current solutions do not
accommodate issues like referencing and publishing. This gap motivated us to
build a platform that integrates the three main functionalities required to
effectively produce scientific publications: a cooperative text editor, a
cooperative reference manager and a connector to scientific digital
repositories. This paper presents this solution, which we called PaperFlow and
was specified with the aid of a study conducted with Portuguese and Spanish
researchers, which results are also presented, with the aim of evaluating the
platform requirements. Keywords: Groupware; Group Editors; Scientific Digital Repositories; Scientific

| 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. Keywords: Software Engineering; Groupware design; Interaction design; Model Based

| Jesús Gallardo; Ana I. Molina; Crescencio Bravo; Miguel A. Redondo; César A. Collazos | |||
| 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. Keywords: Groupware; Collaborative modelling tools; Usability and awareness

| Modeling is a key activity in conceptual design and system design. Users as
well as stakeholders, experts and entrepreneurs need to be able to create
shared understanding about a system representation. Technology like interactive
whiteboards may provide new opportunities in the support of collaborative
modeling. We conduct an exploratory research on experiences in using
interactive whiteboards in collaborative modeling, based on semi-structured
interviews. This paper offers a first overview of advantages and disadvantages
of interactive whiteboards and creates a research agenda to explore how process
support can help in harvesting the efficiency gain that we believe can be
achieved using this technology. Keywords: collaborative modeling; interactive whiteboards; system and design; groups;

| Supporting the System Requirements Elicitation through Collaborative Observations | | BIBAK | Full-Text | 364-379 | |
| Renata Guanaes Machado; Marcos R. S. Borges; José Orlando Gomes | |||
| Many approaches to work analysis have been proposed to enhance the
requirements elicitation for systems design. However, systems delivered at
dynamic, complex and socio-technical workplaces have still failed at satisfying
the users' real needs, mainly because they are unable to support users'
activities entirely, especially those related with cognition and collaboration
aspects. We argue that the use of a combination cognitive and observation
techniques can contribute to enhance the requirements elicitation activity,
particularly if a collaborative approach is also adopted. This paper describes
a collaborative observation model and a collaborative observation method aimed
at improving the quality of the requirements elicitation process. We also
include the description of a groupware prototype that supports our approach. Keywords: Requirements Elicitation; Cognition; Collaborative Observation | |||
