| The TAC paradigm: unified conceptual framework to represent Tangible User Interfaces | | BIBAK | Full-Text | 9-15 | |
| Eduardo H. Calvillo-Gámez; Nancy Leland; Orit Shaer; Robert J. K. Jacob | |||
| This paper introduces a new paradigm for describing Tangible User Interfaces
(TUI). The paradigm presented here encompasses existing TUI classifications and
proposes a unified conceptual framework with which all TUIs can be understood.
In order to show that the new paradigm holds and can be generalized we analyzed
several existing TUIs using the proposed paradigm. Keywords: Pyfo, TAC, Tangible User Interface (TUI) | |||
| A formal approach to the usability engineering | | BIBA | Full-Text | 17-28 | |
| José Creissac Campos | |||
| The quality of an interactive system can be measured in terms of its
usability. Empirical approaches to usability evaluation attempt to assess the
system under real usage conditions. This type of approach can be very
expensive. Analytical approaches have been proposed as a means of reasoning
about usability issues from early in development. These approaches use models
to focus the analysis in specific usability issues. In this context, the
application of (mathematically) formal notations and tools has been proposed.
This paper presents a formal approach to the analysis of interactive systems. The analysis can be carried out taking into account all possible behaviours of the device, or it can be guided by the tasks the device is supposed to support. | |||

| This paper proposes an approach to the development of checklist-based software-usability inspection techniques. More precisely, it is shaped as a cyclic process of planning, construction, application and data analysis, which involves the application of evolutive checklist versions. The whole process is oriented to reach three checklist quality metrics: productivity, effectiveness and systematization of diagnosys. A case study presents the application of such approach to the developpment of a checklist-based usability inspection technique, whose questions are adapted from ISO9241 requirements. This technique is aimed at evaluating the usability of CPqD -- Rede Externa, módulo Operação, a telecommunication network management system, produced by CPqD Foundation. | |||
| Enabling physical collaboration in industrial settings by designing for embodied interaction | | BIBAK | Full-Text | 41-51 | |
| Daniel Fallman | |||
| We describe the efforts of bridging a fieldwork study which used
ethnographic techniques at two industrial assembly sites into a functional
prototype for service and maintenance work. The primacy of the human body and
the mobile nature of such activity are put forward as important design
incentives, which guides the design of the mobile support system. The
situatedness in the physical world is proposed to enable service technicians to
continue to collaborate in a way which is in line with their current work
practice, permeated by physical collaboration, having presence in the world,
and human-to-human interactions. Keywords: embodiment, mobility, physical collaboration | |||
| The standard of user-centered design and the standard definition of usability: analyzing ISO 13407 against ISO 9241-11 | | BIBAK | Full-Text | 53-60 | |
| Timo Jokela; Netta Iivari; Juha Matero; Minna Karukka | |||
| ISO 9241-11 and ISO 13407 are two important standards related to usability:
the former one provides the definition of usability and the latter one guidance
for designing usability. We carried out an interpretative analysis of ISO 13407
from the viewpoint of the standard definition of usability from ISO 9241-11.
The results show that ISO 13407 provides only partly guidance for designing
usability as presumed by the definition. Guidance for describing users and
environments are provided but very limited guidance is provided for the
descriptions of user goals and usability measures, and generally for the
process of producing the various outcomes. Keywords: human-centered design, standards, usability, usability engineering,

| A visual programming environment for device independent generation of user interfaces | | BIBAK | Full-Text | 61-68 | |
| Oscar Mayora-Ibarra; Oscar de la Paz-Arroyo; Edgar Cambranes-Martínez; Alejandro Fuentes-Penna | |||
| The promise of information anytime, anywhere has become a reality. Today, it
is possible to access information through multiple kinds of devices. However,
the design of user interfaces for such devices is restricted to the use of
specific ad hoc programming languages that may vary from one device to the
other. In this sense, the existence of generic programming languages for
creating device-independent user interfaces is becoming a strong necessity. One
emerging approach to device independent developments require the construction
of generic vocabularies for transcoding into specific target codes for web
browsers, PDAs, voice systems, mobile phones, etc. In this work, we present an
authoring tool for designing generic user interfaces with automatic transcoding
to multiple target languages. The tool is a visual programming environment with
drag and drop generic widgets created in UIML and transcoded into VoiceXML,
J2ME, HTML and WML languages. This tool takes advantage of the UIML language
and visual programming paradigms for providing flexibility, consistency and
decrease in development time. Keywords: J2ME, UIML, VXML, WML, XSLT, generic vocabulary, visual programming | |||
| Design with children: a Semiotic approach | | BIBAK | Full-Text | 69-78 | |
| Amanda Meincke Melo; M. Cecília C. Baranauskas | |||
| Human-Computer Interaction literature has shown the importance of bringing
the user to the process of software design and several methodological proposals
have been discussed. This type of user involvement in design is not emphasized
in the same way in software design for children. In this paper we propose a
method based on Semiotic theory for understanding the child's process of
signification for design elements in the Internet media, and reflecting this
understanding in the design of a portal for children. Our approach draw upon
techniques from Participatory Design (PD) and concepts from Organizational
Semiotics (OS). PD has shown usefulness in the investigation of children's
conceptions for Internet spaces, and OS has shown a sound theoretical approach
to represent in ontology charts children's signification to elements of design.
The proposed methodology is illustrated with the design process of
Caleidoscopio Jr: a Web portal for children designed with them. Keywords: information systems, kids, participatory design, semiotics | |||

| From its characteristics, software systems with user interfaces based on
Virtual Reality technology possess bigger complexity in its process of
development, which, in this way, must be supported by more specific
methodologies. However, it is noticed that the development process of these
systems is presented like a line of research to be studied, since it needs to
be better analyzed.
This work presents an including vision of the development process of software systems with user interfaces based on Virtual Reality technology from the viewpoint of the Human-Computer Interaction, analyzing some methodologies found in literature directed to the development of these systems.

| Probabilistic model for the interfaces personalized creation | | BIBAK | Full-Text | 91-96 | |
| Alberto Pedrero; Pablo de la Fuente; Miguel A. Villarroel; Mercedes Martínez | |||
| User interfaces are designed taking in account different user needs
(preferences, abilities, etc.) and various prototypes and usability tests are
carried out during their development. However, when they are used by their
final users, it can be seen that the interfaces do not meet the users
requirements or, more usually, it is evident that the UI can be improved. This
paper presents a system that helps to personalize a user interface for an art
digital library. The system has different predefined interfaces according to
end-user characteristics, but the users can tailor the final appearance of the
information to be showed by the system. From these different adaptations,
tailored by users, the system tries to find similarities that can result in a
modification of the default interface that is presented to new users of the
system. The new interface could be distinct from the one constructed by the
original interface designer. Keywords: adaptive interfaces, personalization, presentation, usability | |||
| Educational software evaluation centered on dialogue: interface, collaboration and scientific concepts | | BIBAK | Full-Text | 97-106 | |
| Flávia Peres; Luciano Meira | |||
| This paper presents a model of software evaluation based on the analysis of
dialogues among users as they explore a math software. Four pairs of 6th
graders were videotaped while solving arithmetic puzzles and operations, and
their talk and actions at the computer transcribed. Using technics borrowed
from Conversation Analysis, we then looked for "breaks" in the emergent
dialogue among the children as well as mismatches between the children's
actions and the software feedback. The suggested model integrates a
user-centered approach based on talk and action and more traditional views of
software evaluation based on features of the interface design. Keywords: conversation analysis, educational software, interface design, software

| Study and analysis of the working space conscience in C debate: a groupware application for collaborative debates | | BIBAK | Full-Text | 107-115 | |
| Manuel Romero-Salcedo; Cesar A. Osuna-Gómez; Leonid Sheremetov; Manuel Chi; Luis Villa | |||
| In this paper, we studied and analyzed the workspace awareness in a
groupware application that allows the development of an information task
through collaborative debates. The application, called CDebate, is based on the
APRI (Action-Perception-Reflection-Intention) model, which establishes a
cognitive and motor states formalization that happen in the human being when
s/he interacts with others in a constructivist learning situation. In CDebate,
the interactions among students occur through a graphical language that
reflects the mental operations appropriated for a debate. As evaluation method,
we used the analytical framework from Gutwin, Stark and Greenberg, which
provides a set of elements that give information about the up-to-date knowledge
about participants' location and actions. The results of our study allow us to
confirm that group awareness information, only supported through a graphical
language, and a window showing the participants' presence (informal awareness),
were enough for the collaborative learning situation. We consider that our
experience could be useful for interface designers of groupware applications,
in particular, for collaborative debate interfaces. Keywords: APRI, CSCL, collaborative debate, group awareness, groupware interface,

| Development of a checklist for the evaluation of the web accessibility for the aged users | | BIBAK | Full-Text | 125-133 | |
| Márcia Barros de Sales; Walter de Abreu Cybis | |||
| This paper presents an approach to create checklists, and to explain how it
is used to develop a technique for assessing the Web interfaces accessibility
focused on aged users. The observation of aged users interacting with a Web
communication tool leaded to the research about recommendations to Web
accessibility, especially those centered on aged users. Thus, the selected
recommendations originated the first version of the checklist, which passed
through three evolutionary cycles of improvement and tests until arrive to the
final version. This paper also intends to sensitize the Web content creators

| What they want and what they get: a study of light-weight technologies for online communities | | BIBAK | Full-Text | 135-146 | |
| Elton José da Silva; Clarisse Sieckenius de Souza; Raquel Oliveira Prates; Ana Maria Nicolaci-da-Costa | |||
| In this paper, we analyze some mismatches between what is offered by
light-weight technologies that support online communities and the dreams and
fears of a group of 20 potential users of such technologies. In our study,
members of an academic community that does not have an online extension
answered an open-ended questionnaire. The answers revealed some of their
expectations about group applications. With these expectations in mind, we
carried out a semiotic inspection of three popular applications. Within the
specific range of topics covered in the study, our findings show three
important factors that seem to determine the distance between what they expect
and what they get: (a) technological resources are limited, but this can be
substantially improved with broad band technologies; (b) some design decisions
are questionable, and should be revised; and (c) online groups must all be
structured and governed by some strict rules, regardless of how informal and
loose they might be offline. Factor (c), in particular, seems to be tied to
deeper scientific issues involved in the inherent social-technical gap of
computer technologies for groups. Keywords: Underlying Discourse Unveiling Method (UDUM), group applications, online

| Visual exploration of large collections in digital libraries | | BIBAK | Full-Text | 147-157 | |
| Nabani N. Silva; J. Alfredo Sánchez; Carlos Proal; Christian Rebollar | |||
| Though conceptually very powerful, Visual Information Seeking (VIS) has been
demonstrated with only relatively small collections of a few thousand items,
which makes it possible to keep entire collections in main memory and perform
recalculations and rendering in real time as the user manipulates sliders and
filters in an interactive fashion. For vast digital libraries, collections may
include hundreds of thousands, millions or even more items. We describe EVA2D,
a visualization environment that implements and extends the notion of Visual
Information Seeking (VIS) to facilitate the exploration of large collections
comprised by digital libraries. This is accomplished by introducing four main
features into EVA2D: pre-computation of graphical data, simultaneous
bi-dimensional selection (direct zooming), precision filtering mechanisms, and
quasi-immediate feedback. Keywords: digital libraries, large collections, starfield displays, visual information

| Evaluation of a visual interface for gesticulation recognition | | BIBAK | Full-Text | 159-165 | |
| Víctor Hugo Zárate Silva; Héctor Hugo Avilés Arriaga | |||
| The automatic recognition of gestures is a well known area, but on the other
hand, the usability of these type of human-machine interfaces has not been
deeply taking into account. This paper shows the results of evaluation of a
man-machine interface, from two points of view: i) automatic recognition and;
ii) usability from the point of view of the end-users. We choose 5 gestures
focus to control a mobile robot. With 8 end-user, the interface gives a 59.46%
of good results when using Dynamic Bayesian Networks, a better result than
using Hidden Markov Models that obtained an average of 43.03%. This result
contrasts with the 84.01% with only one end-user, showing the difficulties to
extend the number of end-users to the system. The usability of the interface
was tested using 6 of the 8 end-users, divided into 3 categories: expert,
semi-expert and non-expert end-users, the result shows a closer perceptions
between expert and not-expert end-users. Keywords: dynamic Bayesian networks, hidden Markov models, usability, visual

| A method of Semiotic engineering for the online help systems construction | | BIBAK | Full-Text | 167-177 | |
| Milene Selbach Silveira; Clarisse Sieckenius de Souza; Simone D. J. Barbosa | |||
| Online help systems are typically used (if at all) as a last resource in
interactive breakdown situations. In this paper, we present a semiotic
engineering method for building online help that uses fairly known design
models. We discuss the benefits of having designers explicitly communicate
their design vision to users and the need or opportunity to foster new cultural
attitudes towards online help. We show how, as a direct communication channel
from designers to users, it opens new possibilities for interaction that can be
skillfully used by designers. By exploring such possibilities, designers and
users may bring about more positive attitudes towards online help and counter
the feeling of technological exclusion which many users express. Keywords: HCI design, design models, online help systems, semiotic engineering,

| About the requisites analysis to the interface project: a subjectivist approach for the information systems | | BIBAK | Full-Text | 179-190 | |
| Carlos Alberto Cocozza Simoni; M. Cecília C. Baranauskas | |||
| The fields of Information Systems (IS) and Human-Computer Interaction (HCI)
have both experienced a move from an exclusively objectivist perspective to the
inclusion of interpretative and subjective aspects in system design. This paper
aims at constructing a semiotic-based referential to model user requirements
reflecting them in the interface design. The proposed approach is illustrated
with a case study in which three teams of academics with practical knowledge in
software development were exposed to the methodological referential to model a
real problem using methods and techniques from Organizational Semiotics. From
this modelling, interface prototypes were built and we could observe that they
had reflected the language, rules, navigation and spaces represented in the
models. The results achieved suggest that the theoretical referential seems to
be an appropriate foundation for understanding a subjective view to information
systems, and a guiding concept for joining HCI and IS projects. Keywords: Interação Humano-Computador, Semiótica Organizacional,

| XICL: a language for the user's interfaces development and its components | | BIBAK | Full-Text | 191-200 | |
| Lirisnei Gomes de Sousa; Jair C. Leite | |||
| More interactivity with better usability in Web Systems requires the
development of user interface components with interaction techniques that are
more powerful and popular among the users such as the WIMP style. This work
presents the XICL, a markup language to describe the user interface and its
components. This language defines a description format and a semantic model
that standardizes components programming and increase reuse, extension and
portability. We also present the XICL Studio, a development environment
composed of an editor, a component library and a compiler. Our proposal is
based only in recommended technologies and free software. Keywords: user interface component, user interface design, user interface languages | |||
| A model for the conversation multimodal man-machine: integration of speech and action | | BIBAK | Full-Text | 201-207 | |
| Luis Villaseñor; Manuel Montes; Jean Caelen | |||
| One major goal of human computer interfaces is to simplify the communication
task. Traditionally, users have been restricted to the language of computers
for this task. With the emerging of the graphical and multimodal interfaces --
where the interaction is day by day easier and simpler -- the effort required
for working with a computer is decreasing. However, the problem of
communication is still present, and users continue caring about the
communication task when they deal with a computer. Our work focuses on
improving the communication between the human and the computer. This paper
presents the foundations of a multimodal dialog model based on a modal logic,
which integrates the speech and the action under the same framework. Keywords: cooperative dialogue, human-computer communication, multimodal interaction,

| Older adults and the usability of speech interaction | | BIBAK | Full-Text | 209-215 | |
| Mary Zajicek; Andrew Lee; Richard Wales | |||
| The main aim of this paper is to outline how a new technology, Voice XML can
be used to provide Internet access for older adults who do not have a computer.
The design of the Voice XML dialogues which enable the interaction is informed
by the experience of workers on the Age Resource Desk at Age concern
Oxfordshire and comments from their clients who experimented with a VoiceXML
system. It is hoped that systems such as the ones described in this paper will
to address the challenge of enabling older adults to participate in ICT. Older
people often have little knowledge of computing and in addition age associated
impairment particularly memory and sight loss make using standard desktop
computers difficult. The new solution put forward here uses XML based
technology to provide alternative forms of Web access through VoiceXML which
offers Web access over the telephone and a grammar system from which to build
dialogues. The design of the Voice XML dialogues is crucial to the success of
the system. Although there is no need to learn how to use a computer, speech
systems also pose some problems for older adults.
This paper describes special features in the dialogue which help older adults to use the system and reports experiments carried out to see how successful the dialogue was for older adults. It is acknowledged that the special design put forward in this paper does not help older adults alone. Features which help users to remember how to use a dialogue are useful for everybody.

| As computer technologies become more pervasive new challengers will emerge,
requiring approaches that reach out beyond a single mind interacting with an
isolated technology in a social, cultural, and historical vacuum. This paper
briefly presents new tendencies in HCI to studying the human interactions
mediated by technologies in the context of their social practices, and a
prominent framework, distributed cognition, as a new theoretical underpinning
for HCI. To illustrate the challenges of this new context, findings from a

| Doctors' meetings are very important to discuss patient examination,
treatment and diagnosis of rare diseases. However, sometimes is hard to
congregate people in the same workplace. The aim of videoconference systems is
to propose an alternative for this problem. It helps people to analyze x-rays,
laboratory results and other documents in a collaborative way. It also allows
interaction by using an audio-visual component for sharing annotations in a
common whiteboard. The success of groupware applications depends on user
interface characteristics. This work presents the design of a videoconference

| This paper presents a study in which we manipulated the interface of a
computer simulation into: graphical and numerical formats. We obtained both
performance and eye-tracking learning curves from individuals assigned to one
of these two conditions. Our findings indicate that although performance is not
different between the two interfaces, the amount of attention as measured by
the number of eye-tracking points was very different in the graphical and
numerical conditions. Attention increased over time in the numerical condition,
but was stable in the graphical condition. These results showed that the
strategies used to make decisions in dynamic environments vary according to the
form of information presentation. Keywords: attention, eye-tracking, graphical and numerical interface | |||
