IDENTIFYING, RELATING, AND EVALUATING DESIGN PATTERNS FOR THE DESIGN OF SOFTWARE FOR SYNCHRONOUS COLLABRATION.
Full text linkMany working environments require that geographically distributed or colocated
work group members work together - supported by software - in
developing and refining one commonly shared resource in the same time.
In Computer-Supported Collaborative Work, this is defined as synchronous
collaboration. Domains subject to such type of collaboration are many,
some such examples are drawing, searching, text editing, or game solving.
Technology has helped switching from the real to the virtual, simplifying
such collaborative efforts and providing technological support for more efficient
and faster collaborations. Several software applications, developed as
either research projects or commercial products, exist and are used today in
synchronous collaborative settings in domains such as drawing, searching,
text editing, and game solving. In order to further support such developments,
there is a growing need for knowledge capturing and sharing with
respect to the challenges and the concerns to be faced in designing such
tools. Surely, documentations of existing applications help, but it is only a
larger and perhaps more general repository of knowledge that would do a
better job.
Several approaches for building such repositories of knowledge exist, the approach
this thesis is further exploring is design patterns. On one hand, I aim
at bringing methodological support to design pattern research in answer to
the scarce landscape of methods and techniques for both identifying design
patterns in interaction design and generating pattern languages based on
existing collections of patterns. I focus mainly on one area of interaction
design, i.e. the design of applications addressing synchronous collaboration,
and I target four domains in the area, i.e. drawing, text editing, searching,
and game solving. On the other hand, I am interested in better understanding
how design patterns are used and what is the impact of using them in collaborative design processes. I first focus on the collaborative
processes involving novice designers, aiming to correlate the findings from
this initial study with those obtained after investigating similar processes
involving experienced users of patterns.
This work primarily impacts design pattern research at a methodological,
theoretical, practical and empirical level. Secondarily, the findings
described throughout the thesis inform behavioural research and humancomputer
interaction. At a methodological level, I describe two methods
addressing design pattern research; one is used for identifying design patterns
in interaction design, while the second one is used for generating pattern
languages out of existing collections of patterns. At a theoretical level,
I describe the results of applying the pattern identification method in the
area of synchronous collaboration, providing 15 design patterns addressing
the design of applications targeting this area. Practically, I developed a
software application able to support the semi-automation of the pattern
language generation method and the execution of queries on the output
of this generation process. At the empirical level, I present a case study
designed to bring some light into the matter of collaborative use of design
patterns. The results of this case study aim at identifying strategies
novice designers develop while collaboratively using design patterns during
interaction design processes
On the use of design patterns in collaborative design processes
Full text linkEven if the usefulness of a knowledge repository represented as a collection of design patterns is largely recognized in the literature, little work has been done in investigating and measuring the impact such a collection would have on collaborative design processes involving designers. The paper describes the results of a case study designed to bring some insight into the matter. 18 design workshops were conducted with 18 teams of undergraduate students in Computer Science. Making use of a collection of design patterns for the design of synchronous applications, they were asked to design the GUI and the interaction process of applications which support synchronous collaboration in activities such as drawing, text editing, game solving, and searching. To answer the questions addressed by the case study, the results of the workshops were triangulated from: i) audio recordings of the conversations of each team, ii) notes taken on the participants interactions by a facilitator present during the workshops, and iii) feedback provided by each participant through a questionnaire, at the end of each workshop

New design strategies: Using the Hive Mind Space model to enhance collaboration
No full textAs collaboration in creating information systems becomes more frequent and more important among multi-disciplinary teams, finding new models for coordinating this collaboration becomes crucial. Supporting end users' collaborative design, therefore, calls for a new design strategy. This paper addresses the challenge of bridging communication gaps raised during collaborative design activities, with a meta-design/socio-technical approach - namely, design for participation and creative collaboration. This model provides an integrated habitable space bringing diverse Communities of Practice (CoPs) together to actively participate in the design activities and to collaboratively solve design problems.The model highlights a boundary zone, serving as a common meeting space supporting communication and message exchange among CoPs. The emphasis on exchanging and creating boundary objects within the boundary zone provides a means to overcome the communication gaps among CoPs. The paper describes the overall structure of the HMS exploits the affordances of a Hive Mind Space (HMS) and depicts the flow of reasoning used in applying it on a real development case in factory automation domain
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
