| Equator: mixing media and showing seams | | BIBAK | Full-Text | 1 | |
| Matthew Chalmers | |||
| The Equator interdisciplinary research collaboration has been exploring the
combination of media such as mobile devices and collaborative virtual
environments. We have built collaborative systems for a number of application
areas including cultural heritage and tourism, performance, games, medical
monitoring and environmental science. These systems have generally involved
online visitors to a building or the city streets interacting with on-site
visitors to the building or the streets. Sometimes the people online, using new
media, are also on-site, using old media. Overall, Equator explores the
interconnection and interweaving of activity in heterogeneous media which are
usually treated in an isolated way. A number of higher-level design concepts
have either motivated this work, or have arisen from experimentation with and
evaluation of such systems. In this talk I offer my perspective on Equator's
approach to ubicomp and HCI, giving examples of system designs, user
experiences and conceptual work, and how they too are interconnected and
interwoven in our research. Keywords: CSCW, seamful design, seams, ubiquitous computing | |||

Belgium, and the action of the BlindSurfer initiative. Keywords: Belgium, BlindSurfer, accessibility, handicap, visual, website | |||
| Les leçons tirées des deux compétitions de visualisation d'information | | BIBAK | Full-Text | 7-12 | |
| Jean-Daniel Fekete; Catherine Plaisant | |||
| Information visualization needs benchmarks to carry on. A benchmark is aimed
at comparing information visualization techniques or systems. A benchmark is
made of a dataset, a list of tasks mostly based on finding facts about the
dataset, and a list of interesting or important findings about the datasets
(the nuggets to find). For the second year, we are organizing the InfoVis
Contest aimed at collecting results for benchmarks. We describe here the main
lessons we learned. Keywords: benchmark, contest, evaluation, information visualization | |||
| Couplage de ressources d'interaction | | BIBAK | Full-Text | 13-20 | |
| Nicolas Barralon; Christophe Lachenal; Joëlle Coutaz | |||
| Although coupling interaction resources is key to ubiquitous computing, this
notion has been overlooked in previous studies. In this paper, we address this
notion in a more systematic way by describing coupling as a finite state
machine whose states should be maintained observable and controllable by users
in a flexible and reliable manner. We illustrate the discussion with state of
the art demonstrators as well as with I-AM, a middleware that supports the
dynamic construction of multi-screen, multi-keyboard, and multi-pointer
interactive spaces. Keywords: interaction resources coupling, interaction technique, ubiquitous computing | |||
| De la représentation de l'interlocuteur vers un modèle utilisateur formel pour le dialogue personne-machine | | BIBAK | Full-Text | 21-28 | |
| Philippe Bretier; Ludovic Le Bigot; Franck Panaget; David Sadek | |||
| This paper proposes the formalization and implementation of user model. It
is based on an interlocutor's model in natural language dialogue system.
Experimental studies on interlocutor's representation and, particularly, on
user's familiarization with the system were used for the results analyses. The
analysis of the results has shown the more the user is familiarized the more he
gives relevant information for research in his first utterances, and with the
same number of words. The formalization proposed concerns (1) user's expertise
or familiarization level, and (2) the detection of this level. The extended
user model allows the system to adapt and thus, to contribute to increase
usability and its efficiency in the information research processes. Keywords: dialogue, interlocutor model, natural language, user model | |||
| Conception participative par « moments » | | BIBAK | Full-Text | 29-36 | |
| Jean Caelen; Francis Jambon | |||
| This paper describes an approach for the participatory design. After
describing the trends in the domain, a formalization of the design process is
expressed based on ëphaseû, ëmomentû and
ëprimitiveû. The phases articulate the design moments as nodes and
transitions in a dynamic graph. The moments are built on reusable primitives
defined as instanciable objects. Then, the paper details with this formal model
a platform and tools for managing the design process on different points of
view: from the user and engineers to the project manager. Keywords: participatory design, platform for experiments | |||
| Modélisation de l'interaction collaborative dans les systèmes de Réalité Mixte | | BIBAK | Full-Text | 37-44 | |
| René Chalon; Bertrand T. David | |||
| This paper deals with the problem of interaction modeling in Mixed Reality
(MR) systems. After reviewing existing HCI models, and pointing out their
limits in MR context, we present our model called IRVO (Interacting with Real
and Virtual Objects) which aims to help to design MR systems. Then we propose
taxonomy for MR systems based on IRVO model. Finally, we investigate the
utility of the model for the design phase, and we show how it links to other
HCI models. Keywords: augmented reality, collaborative work, interaction model, mixed reality | |||
| Vers des outils pour les équipes de conception d'interfaces post-WIMP | | BIBA | Full-Text | 45-52 | |
| Stéphane Chatty; Stéphane Sire; Alexandre Lemort | |||
| Programming highly interactive user interfaces remains a complex task with the available software tools. Interviews and observation of 50 design or production teams of industrial products shows the importance of group production between graphics designers, programmers, usability experts and the lead designer. Tools must allow each of them to efficiently produce their part. That imposes new constraints on the architecture of interactive software. We present the solutions used our development suite, Intui-Kit, designed to bridge the gap between interface design and software engineering. We illustrate it on a concrete product development. | |||
| Composant logiciel vs physique pour interagir avec un espace de valeurs temporelles | | BIBAK | Full-Text | 53-60 | |
| Chaouki Daassi; Laurence Nigay; Marie-Christine Fauvet | |||
| Timelines are recurrently used to design visualization techniques of
temporal data. In this paper, we present our perspective wall timeline to
visualize temporal values. We illustrate how our timeline could be used by two
examples of visualization techniques of temporal data: the star representation
technique and the superposed histograms technique.
In this paper, we propose to use a dedicated physical device for the perspective wall timeline, making the reusable corresponding software component a reusable physical device. Then, we present the results of an experiment we have conducted to compare the time device to the timeline (software component). Finally, we conclude and present our perspectives. Keywords: evaluation of user interfaces, physical device, temporal data visualization,

| Emmanuel Dubois; Benoît Mansoux; Cédric Bach; Dominique Scapin; Guillaume Masserey; Joël Viala | |||
| This paper describes a multidisciplinary approach to the modelling of the
mixed reality systems domain. Such modelling, useful for structuring such a
recent interaction domain, and to facilitate design and evaluation from both
software engineering and ergonomics perspectives, is based on the combination
of two approaches: the ASUR notation and an ergonomic recommendations-based
model. Both approaches are presented as well as the results of their
combination. The resulting model, an extension of the ASUR notation, is
described as well as its limits and perspectives. Keywords: ASUR notation, domain model, ergonomic recommendations, mixed systems | |||
| La boîte à outils InfoVis | | BIBAK | Full-Text | 69-76 | |
| Jean-Daniel Fekete | |||
| This article presents the InfoVis Toolkit, designed to support the creation,
extension and integration of advanced 2D Information Visualization components
into interactive Java Swing applications. The InfoVis Toolkit provides specific
data structures to achieve a fast action/feedback loop required by dynamic
queries. It comes with a large set of components such as range sliders and
tailored control panels required to control and configure the visualizations.
These components are integrated into a coherent framework that simplifies the
management of rich data structures and the design and extension of
visualizations. Supported data structures currently include tables, trees and
graphs. Supported visualizations include scatter plots, time series, Tree-maps,
node-link diagrams for trees and graphs and adjacency matrix for graphs. All
visualizations can use fisheye lenses and dynamic labeling. The InfoVis Toolkit
supports hardware acceleration when available through Agile2D, an
implementation of the Java Graphics API based on OpenGL, achieving speedups of
10 to 1000 times. Keywords: advanced interaction, graphics, information visualization, toolkit | |||
| Comparaison de la lisibilité des graphes en représentation noeuds-liens et matricielle | | BIBAK | Full-Text | 77-84 | |
| Mohammad Ghoniem; Jean-Daniel Fekete; Philippe Castagliola | |||
| This article describes a taxonomy of tasks on graphs and a controlled
experiment for assessing the readability of two graph representations: matrices
and node-link diagrams. The experiment only concerned a subset of the described
tasks but provides important insights on the use of representations depending
on the graph sizes and densities. It shows that, for graphs larger than 20
nodes or sufficiently dense, most tasks are performed more efficiently on the
matrix-based representation. Only some path related tasks score better on
node-link diagrams. Keywords: adjacency matrices, evaluation, node-link representation readability,

| Svalabard: une table à dessin virtuelle pour la modélisation 3D | | BIBAK | Full-Text | 85-92 | |
| Stéphane Huot; Cédric Dumas; Gérard Hégron | |||
| This paper introduces a perspective sketching interface for creative 3D
modeling: Svalabard. To close the gap between designers' abilities and 3D
modeling tools, our proposal is a freehand sketching tool, metaphor of a
drawing desk. Interactions and tools take advantage of designers work habits
(multilayer drawing, association of interactions with input devices). Svalabard
includes background drawing filters, developed from a user study in the
architectural domain. Those filters detect the current drawing context in
real-time to adapt the interface and clean the sketch. Finally, the result of
the filters is a structured representation of drawn 3D volumes. Keywords: 3D modeling, contextual interaction, creative design, perspective sketch,

| Christophe Jacquet; Yacine Bellik; René Farcy; Yolaine Bourda | |||
| In this paper, we present an overview of current electronic locomotion aids
for the blind and perspectives for future systems. We start with the two main
issues raised by locomotion assistance for the blind: how to capture and
present information. Then, we explain how these issues have been dealt with in
existing devices, and we describe the techniques that have been used to solve
them: infrared, ultrasonic and laser sensors to capture information; tactile
and audio modalities to present information. After that, we expose some current
ideas and results about a new generation of context-aware, semantics-enhanced
locomotion assistance devices, that are expected to provide higher-level
information than current ones do. Keywords: autonomy, blind People, context-awareness, electronic travel aids,

| Nicolas Plouznikoff; Jean-Marc Robert | |||
| This article presents an overview of the characteristics, issues and
challenges of wearable computing. Wearable computers are worn on the body. They
possess four fundamental characteristics setting them apart from traditional
computing devices: they are mobile, constantly available, (pro)active and can
be used in a relatively transparent way. Their role is to assist a user who
moves about while accomplishing real-world tasks. Since they are carried by the
user and must face severe constraints of weight, size, seamless use, etc.,
their interface has a definite impact on user acceptability, and eventually on
human performance and satisfaction. We analyze the characteristics of various
input and output peripherals, and their impacts on human perception and
cognition. We then emphasize the inadequacy of the peripherals and interaction
mechanisms of traditional computers for wearable computers. Finally, we give
several examples of tasks and application domains that could make good use of
wearable computers. Keywords: human-computer interfaces, mobile computing, wearable computer | |||

| We have developed Zoé, a software solution dedicated to CVs'
management. In order to ensure its strongly graphical and interactive aspect we
have used the PAC-Amodeus Software Architectural Model for GUIs. This approach
allowed us to very quickly and easily develop a simplified version of this
software: Léa. After a brief reminder on the PAC-Amodeus model we give
indications on how to implement it efficiently in the context of a large
program (more than 2000 classes) written in Java, a programming language which
allows only simple inheritance. Keywords: design patterns, efficient implementation of software architectural models,

| EsQUIsE-SMA: un système multi-agents pour l'interprétation d'esquisses architecturales | | BIBAK | Full-Text | 179-180 | |
| Roland Juchmes; Pierre Leclercq | |||
| Architects use freehand sketches in the initial stages of their design work
because they prove to be the best adapted media for handling and expressing
their preliminary ideas. Therefore, to help designers in their inventive work,
a means for inputting and interpreting their sketches was needed.
We propose a multi-agent approach to attain that goal. In this paper, we describe the operations of a multi-agent system for the on-line recognition of sketches. This system is currently integrated into the EsQUIsE prototype, a demo program for inputting, analysing and interpreting architectural design sketches.

| De la visualisation à la manipulation directe d'information avec ILOG discovery | | BIBAK | Full-Text | 183-186 | |
| Thomas Baudel | |||
| Nowadays generic database systems (such as accounting and financial
software, customer relationship management systems, logging and tracking
software...) provide mostly forms and menu based interfaces that do not take
advantage of the graphic and interactive capabilities of current hardware. This
is because the data they handle does not have intrinsic visual representations
upon which direct manipulation principles could be used. This article presents
how we have extended an information visualization framework which allows to
create and to interactively transform easily rich data views, with generic data
manipulation functions tuned to take advantage of each view's characteristics.
These editing capabilities enable us to generalize the mechanisms of direct
manipulation to address all sorts of massive abstract data manipulation needs. Keywords: database user interfaces, direct data editing, direct manipulation,

| DoPIdom: une boîte à outils pour la conception d'interfaces centrées sur les documents XML | | BIBAK | Full-Text | 187-190 | |
| Olivier Beaudoux | |||
| The concept of document usually refers to data that documents contain, but
rarely with actions that documents can handle. As a consequence, it is hard to
specify how users can interact with documents: this is mainly done with
dedicated applications that users have to juggle in order to achieve a single
editing task. This paper presents DoPIdom, a user-interface toolkit designed to
create interactive environments centered on XML documents. It is based on the
DPI (Document, Presentation, Instrument) model, which aims at hiding the
concept of application from the user point of view. Keywords: GUI toolkits, document model, interaction model, software components | |||

the still important problem of tailorability inside CSCW systems. Our
proposition aims at favouring the dynamic integration of groupware systems in a
global and integrated environment that creates a context for their use. This
work leads us to define the problem of the inter-activities management. This
study helps us to propose a technical solution to this problem and that is
realized in the CooLDA platform. Keywords: CSCW, groupware, integration, interactivities, tailorability | |||
| Palette hyperbolique: un outil pour interagir avec des ensembles de données | | BIBAK | Full-Text | 195-198 | |
| Kamel Chelghoum; Maurice Margenstern; Benoît Martin; Isabelle Pecci | |||
| Manipulations and exploration of large data sets are common problems. This
paper aims at adapting a fisheye technique that uses hyperbolic geometry.
Unlike the classical approach, the hyperbolic space used in our research is
tiled. The tiling method proposed supplies a code for data that ensures the
neighbourhood between data. The difficulty lies in finding how to distribute
data through the tiling. We give some heuristics to better target suitable data
sets. Our research results in defining an interactive tool for manipulating
such data sets: the hyperbolic palette. To illustrate the various possibilities
of this tool, a prototype application was developed. Its goal is to provide a
new palette to select a colour out of 16 million options. We show in this paper
why such an application fulfills our heuristics to use an hyperbolic palette. Keywords: fisheye view, hyperbolic geometry, large data spaces, visual exploration | |||

mobile telephones. Considering the very reduced size of a mobile telephone
screen, its weak resolution and the great volume of data to be represented, we
suggest condensing the information beforehand. The data are first treated with
a standard technique of classification before their visualization. For
visualization, we propose two methods of traditional representation (Bar Chart
and Table) and two more recent methods (Pixel Bar Chart and Spirale). Keywords: clustering, mobile phone, visualization | |||

| TrackMouse: une solution 4D pour des interactions avec deux curseurs | | BIBAK | Full-Text | 231-234 | |
| Benoît Martin | |||
| Desktop applications are more and more sophisticated. Often, the user needs
several degrees of freedom to accomplish his task. One solution is to provide
two independent cursors for some types of interactions but this solution is
mainly used in two-hands interactions. The objective of this paper is "one
user, one hand, two cursors". We propose the TrackMouse, a multimodal input
device for interactive applications based on the simultaneous use of two
cursors. It is an evolution of the Logitech force feedback mouse by adding a
trackball to offer the degrees of freedom needed to control the second cursor.
To manage the TrackMouse, an API for Windows XP is described too. Thus, a
sample of application shows some new possible interactions. Keywords: multi modality, multiple cursors interactions, multiple mice systems | |||

have made the use of these applications more and more cumbersome. In this
paper, we present Circa, a software infrastructure designed for personal
communication with close relations by way of groups. Circa provides users with
a simple and unique interface to manage groups of individuals, independently
from applications. Circa also facilitates the implementation of communication
applications by taking care of the low-level details related to data

| VisuThread: un module de visualisation de conversations électroniques | | BIBAK | Full-Text | 239-242 | |
| Benoît Otjacques; Fernand Feltz | |||
| Electronic messaging has become one of the most widely used software in the
enterprises. Increasingly its usage goes beyond the scope for which it was
initially designed. For instance, the users consider it as a tool supporting
the management of their tasks. The inappropriateness of current e-mail clients
becomes more and more patent. Several research works have studied how to
enhance its functionalities, especially in the domain of graphical
representation of information. This paper describes 'VisuThread', a
conversation visualization module integrated in an electronic messaging client.
The proposed graphical representation aims to allow a rapid apprehension of the
current state of a conversation. It highlights the chronological succession of
messages as well as the participants to the conversation. Moreover, additional
useful functions are also integrated, such as filtering, zooming, or access to
the message editor. Keywords: electronic messaging, graphical representation, thread visualization | |||
| Une interface conversationnelle pour les agents assistants appliqués à des activités professionnelles | | BIBAK | Full-Text | 243-246 | |
| Emerson Cabrera Paraiso; Jean-Paul A. Barthès | |||
| This paper describes the design of a speech and natural language dialog
interface for personal assistants. We are specially interested in working with
personal assistants in professional domains. We believe that the use of speech
will facilitate the interaction between human and machine, since the user may
speak with the agent using her own terms, increasing the quality of the
assistance. The main difficulty in our approach however is to handle spoken
natural language, and to understand its actual context. To overcome such
difficulties, we restrict the exchanges to Directives Speech Act classes:
inform, request, or answer.
We present a conversational speech interface architecture in a multi-agent system applied to personal information management. As a clear result, we expect an increase in the quality of the interface and of the assistance to the user, which seems to be the case on preliminary results.

| Une description probabiliste de la communication parlée entre homme et machine | | BIBAK | Full-Text | 247-250 | |
| Olivier Pietquin | |||
| This paper presents a formalism for the description of man-machine spoken
communication in the framework of spoken dialogue systems. This formalisation
is based on a probabilistic description of the interaction and of the
information processing occurring in each module composing a spoken dialogue
system. Eventually, some possible applications of this theoretic framework to
the problem of dialogue systems' design are proposed. Keywords: natural language processing, speech processing, spoken dialogue systems | |||

| The navigation is one of the most critical aspects of web applications since
it supports most of user interaction. Even though navigation models may help
designers to deal with complex and large web applications the modelling itself
cannot ensure its correct implementation. This paper presents a MVC
architecture which employs abstract navigation models (built with the SWC
notation) to implement the effective navigation made available to the users. Keywords: dialog control, navigation modelling, web applications | |||
| Modèle d'architecture pour la conception de systèmes multimodaux en sortie | | BIBAK | Full-Text | 255-258 | |

| Output multimodality consists in presenting information to the user in an
"intelligent" way by exploiting different communication modalities. This
presentation must be the most suitable to the interaction context. In this
paper, we present a global architecture framework to support output multimodal
systems design and more precisely mechanisms tailoring the information
presentation according to the interaction context. Two applications of this
architecture framework (mobile telephony and military avionics) are also
presented. Keywords: human-computer interaction, interaction context, multimodal system, output

| If Web usability guidelines can play an important role for ensuring
usability when designing and evaluating web application, the moment and the way
to use them still remain unclear. This paper presents a preliminary study and a
classification of ergonomic rules about web applications navigation. Secondly,
we describe our approach to apply these rules directly to a navigation model
(SWC). Keywords: SWC, ergonomic rules, evaluation, navigation modelling, web applications | |||
| Acuité perceptive via une interface pseudo-haptique | | BIBAK | Full-Text | 263-266 | |
| Mounia Ziat; Olivier Gapenne; Charles Lenay; John Stewart | |||
| The goal of this study is to apprehend the perceptive training capacities of
a human subject via an artificial device and to also underline their limits and
constraints. The principal constraint considered here, is the acuity in other
words, the spatial proprieties ratio of the sensor and the explored objects.
The experimental device couples the pen of a graphics tablet with tactile
sensory stimulators. A matrix of virtual receptor field linked to a stylus by
means of an equipped computer is responsible for the stimulator activation. The
results show: i) that the subjects are able to perceive forms via this
artificial device and that this perception is forced by the spatial resolution
of the sensor, ii) That the subjects are able to adapt their movements to
perceive very small forms (0,5 mm height), iii) To develop new exploration
strategies. Keywords: acuity, graphical interface, perceptual training, sensory substitution | |||
