| Cognitive assistance systems are aimed to support people loosing their
autonomy while completing activities of daily living (ADL). The range of
activities to support, the dissemination of interactive devices in the
environment and the variability of users' cognitive capacities raise real
challenges when designing assistance in such systems. This paper addresses the
assistance issues and presents guidelines for assistive systems design.
Especially, based on an experiment of the assistance provided while completing
ADL, we suggest a principle of scaled assistance. The principle was applied to
Archipel, a cognitive orthesis. This application and the results analysis of a
12 subject experiment led to the evaluation and the improvement of some
ergonomic guidelines about ambient assisted living. Keywords: ambient assisted living, assistive system design, smart homes, usability | |||

| This paper examines usage acceptance of "aging in place" services dedicated
to elderly people. The aim of this study is to investigate causal link between
behaviour prediction and service intention to use. Besides direct effects of
utility and usability on behaviour intention, we expected that prescriptive
behaviour would be best predict by social determinants rather than other
behaviours. We tested our hypothesis with 157 elderly people (M: 75, 1 years
old; SD: 6, 5). Using Partial Least Square path modelling approach (SmartPLS
software), our findings tend to demonstrate on the one hand that utility and
usability have direct link with behaviour intention. On the other hand,
subjective norms and attitudes influence alternately intention when service
behaviour imply prescription. Keywords: ICT service evaluation, acceptance, aging in place, intention prediction | |||
| Système de saisie de texte visant à réduire l'effort des utilisateurs à handicap moteur | | BIBAK | Full-Text | 19-26 | |

| The K-Thot virtual keyboard system presented in this paper aims to decrease
the effort (especially movements) needed to make a text input and is intended
for users who have difficulty entering data on a physical keyboard. As part of
this article, we present a virtual keyboard typing to replace a physical
keyboard. K-Thot is composed with ten keys, each containing four characters,
one by cardinal point. Entering a character is done by selecting the key
containing it and making a cursor leave on the side where the target character
is. Four devices will be proposed, The first one will use the classical AZERTY
layout, the second one will use an alphabetical order, the third one will be
organized (provision created by an algorithm) and the last one will be a
dynamic layout (once a letter has been validated, the keyboard rearranges the
letters on the keys to present first those with the highest chance of being
captured later, thanks to statistics provided by the N-grams). After an
analysis of similar systems, K-Thot is explained in detail. Early results from
preliminary experiments are provided and discussed. Keywords: handicap, human-machine interaction, text entry | |||

| Fabien Denise; Catherine Cléder; Sylvie Girard; Isabelle Audras | |||
| During software deployment in schools, we observed a lot of solicitations of
teacher by children. The major goal of such solicitations was for children to
ask for navigation help. The type of questions and associated answers vary
according to the child and the evaluation of learning situation. This article
will discuss the benefits in terms of usability of educational software that
include an intelligent and emotional companion as support navigation help for 6
years old children. Building on the results of experiments of Iroplan (a
computer assisted learning system to help in the apprenticeship of reading), we
analyze the interactions induced by the three entities: Teacher -- Computer --
Learner. Then, we'll overview a state of art on the use of companions in
educational software. Third, we present Tago -- the companion created for
Iroplan -- under its HCI and AI aspects. The version of Iroplan with Tago has
been the subject of a usability test on 26 children whose first result will be
exposed in the last part, along with their adequation in answering the
interaction issues aforementioned. Keywords: AI, HCI, affective computing, embodied pedagogical agent, learning,

| Emotional facial expression interface: effects of displayed facial designs | | BIBAK | Full-Text | 37-43 | |
| Damien Dupré; Michel Dubois; Nadine Mandran; Anna Tcherkassof | |||
| In supporting the visual-mediated emotional recognition, little research has
centred on analysing the effect of presenting different combinatorial facial
designs. Moreover, in the theoretical field of emotions, research on the
recognition of emotional facial expressions (EFE) is mainly based on static and
posed databases tested in unnatural contexts (explicit recognition task of an
emotion).
Our research has constructed and validated a database, DynEmo, with dynamic and spontaneous emotional facial expressions. So different facial interface designs (whole face, zoomed face, eyes + mouth, whole face + mouth, whole face + eyes, etc., n = 11) are experimentally compared to find their impact in terms of emotional recognition. The results show the facial interface design relevance in terms of emotional recognition. The application of this work is transferable to facial interfaces useful for video-mediated interaction.

| Media may exert a major influence on behaviours with others or with
machines. In the car driving framework, cinematographic car chases have their
followers. This study investigates the links between cinematographic car chases
appreciation, the subsequent reactions and the driving style of the viewers.
Twenty-four young drivers were rigorously selected. They were either
cinematographic car chases followers or not (A+/A-). They had to
watch short sequences including or not a car chase. Emotional ratings of car
chases scenes are significantly different between groups. Moreover,
electrodermal reactivity is higher for the A+ group in the car chase
condition than in the neutral one. Whereas no difference were observed between
groups concerning the driving experience, the annual mileage and the number of
reported accidents, car chases followers reported better driving skills than
non-followers. Several others relations had been highlighted, emphasising the
complex tangle between reality and fiction. Keywords: car chases, cinema, control, driving, emotions, young drivers | |||
| eMotion: un outil pour personnaliser la reconnaissance d'émotions | | BIBAK | Full-Text | 59-66 | |
| Alexis Clay; Nadine Couture; Laurence Nigay | |||
| A subject's emotional expression is of course influenced by his personality,
but several other factors can play a role. His position, the constraints he
undergoes, or the setting of his working space can all deeply impact emotional
expression through movement. When performing an automatic emotion recognition,
an evaluator must be able to set up some parameters for the recognition so as
to adapt to the evaluation conditions. Current recognition system do not allow
for such adaptability. In this paper we present the eMotion software for
movement-based emotion recognition. eMotion's software architecture allows easy
integration of graphical widgets for parameterising emotional features
extraction to suit the task at hand. Keywords: affective computing, emotion, emotion recognition, evaluation, movement | |||
| Etude du comportement et des émotions dans un contexte de multisollicitations: approche exploratoire avec la Plateforme d'Evaluation, de prototypage et de teSts d'usageS (PEPSS) | | BIBAK | Full-Text | 67-74 | |
| Nadine Couture; Marion Wolff; Régis Mollard; Laurent Todeschini | |||
| This exploratory study presents the results of an evaluation of human
behavior obtained through a first use of the platform PEPSS (Prototyping
platform for evaluating and use tests). During tests, subjects were confronted
with a work situation characterized by multisollicitations induced by different
distractors while performing a monitoring task. Using different tools, we have
collected the performance, their emotional reactions and the subjective
feeling. A multivariate analysis was used to study the behavior of subjects
facing the multisollicitations. These first results open new opportunities for
the analysis of work situations and evaluation of innovative products as the
Platform PEPSS is reconfigurable and adaptable according to new needs. Keywords: emotion, evaluation, interactive behavior, multisollicitations, use test | |||
| Penser "plasticité" peut améliorer la qualité des interfaces homme-machine: une étude de cas | | BIBAK | Full-Text | 77-84 | |
| Audrey Serna; Gaëlle Calvary; Dominique L. Scapin | |||
| In Human-Computer Interaction, plasticity refers to the capacity of User
Interfaces (UI) to adapt to the context of use (<user, platform,
environment>) while preserving user-centered properties. Until now,
plasticity was the scope of various studies. The adaptation from a context of
use to another was studied in order to satisfy the end-user's requirements.
This paper changes the focus: plasticity in itself is not the scope anymore; it
is viewed as a way for designers to improve UI quality. The iterative design
process is detailed for a case study where all design decisions have been
recorded in terms of their influence on UI ergonomic quality. The case study
deals with e-goverment procedures. The return of experience shows that paying
attention to plasticity for a small screen platform results in improvements on
the large screen platform version due to the reexamination of its initial
design. Keywords: design, plasticity, quality, user interface | |||
| Une approche sémiotique du contexte pour les systèmes pervasifs | | BIBAK | Full-Text | 85-92 | |
| Daniel Galarreta | |||
| In this paper we examine the issue of the context for pervasive systems. For
this purpose we adopt a semiotic approach. After a presentation of the
theoretical framework, we try to show that multimodality and viewpoints can
play a key role in understanding the context. We present examples of multimodal
situations which lead us to recommend to give up or at least limit a too
objectivist conception of context in the designing of pervasive systems. Keywords: complex systems, context, context-aware computing, organisational semiotics,

| Prise en compte de l'utilisateur dans le processus de conception d'une application d'édition de modèles de tâches | | BIBAK | Full-Text | 93-99 | |
| Sybille Caffiau; Patrick Girard; Dominique L. Scapin; Laurent Guittet | |||
| Interactive application design iterates on: needs analysis (human and
technical), specification, implementation and validation. In user-centred
design, the specifications of use may be expressed by task models. From these
models and scenarios, some methods allow to design interactive applications.
However, the activity description is not always available (e.g., not provided
by previous designers) or not usable. For instance, task models corresponding
to an editing activity are composed of tasks that are all (or nearly all)
accessible at any time. From such a task model, defining the application
structure (component position, control activation) is a difficult task. In
order to include users in the design process for this type of activity,
designers choose other ergonomics methods such as user testing. This paper
presents how an evaluation of usage for an editor of task models (K-MAD) may be
used in order to modify the application interface. A study of the pertinence of
the modifications (presented in the second part) shows that they imply to
decrease the time to edit. Keywords: evaluation, task models, user-centred design | |||
| Multi-actor systems and its organizational form: planning and communication of dispatchers and passengers in the Netherlands Railways (NS) | | BIBAK | Full-Text | 100-105 | |
| Niels R. Faber; René J. Jorna | |||
| In innovating its planning processes, passenger involvement in dispatching
is one of the directions the Netherlands Railways is exploring. Multi-agent
systems (MAS) provide a way to study the organizational aspects of the
dispatching task that aims to bridge functional differences between passengers
and dispatchers. In this study, besides the technical, especially the
coordinating and organizational implications of such a change will be
investigated. Two versions of a multi-agent system have been constructed:
NS-MAS 1 and NS-MAS 2. The involvement of active passengers as is realized in
NS-MAS 1, provides the organizational specifications of realizing
dispatcher-passenger communication. Furthermore, this implementation provides
indications for bridging the functional differences between passengers and
dispatchers. NS-MAS 2 operates with simulated passive passengers, based on
statistical data of passenger movements, and implements the coordination
possibilities taking into account passenger involvement in dispatching. Keywords: innovation, multi-agent systems, organization, planning | |||

| This article describes the design approach and experience gained when
implementing an original usability laboratory: the MultiCom platform. The
purpose of this platform is the evaluation of the usability and usage of a wide
range of interactive systems: from classic systems to ubiquitous environments.
For this, the platform was designed as a large theater where acts could be
played. The relevance of the design choices (surface, ground plane, automation)
was validated through several experiments that were successfully carried out on
the platform. Keywords: usability/usage laboratory | |||
| Conception d'un hypermédia adaptatif centré sur le style d'apprentissage | | BIBAK | Full-Text | 117-122 | |
| Lamia Mahnane; Med Tayeb Laskri | |||
| This article discusses learning style as an adaptive criterion of an
educational hypermedia system. Our approach is based on the measuring of the
performance of a learner in an objective learning designed according to the
characteristics proposed by Felder, to describe the learning style of a
learner. If the learner's performance is satisfactory, then it is likely that
the content and the proposed pedagogie activities match his/her learning style.
Otherwise, the course design should be adapted. The system uses the formalism
of Bayesian network to modal the dependence between performance, the presented
documents and the learning style. Keywords: Bayesian network, adaptive hypermedia, learning style, the learner, the
pedagogical documents | |||
| Complexité, systèmes et apprentissages. Une réflexion liée à la conception et à l'innovation | | BIBAK | Full-Text | 123-128 | |
| Jean-Michel Larrasquet; Iban Lizarralde | |||
| In this contribution, we are focusing on this side of complexity which is
grounded on omnipresence of interpretation in the production of cognitive
objects in the processes of innovation and design, their organization and
management. Our "socio-cognitive" approach allows highlighting the status of
these objects (particularly the concept of a "system") and also what "producing
knowledge" means in the frame of such processes. This reflection leads us to
(re-) consider the way we have to build "systems" socio-cognitively, to take
life-cycles into consideration and to begin to think about the development of
knowledge and competences that actors (particularly project managers) need in
order to intervene cleverly in the management of such projects of innovation
and design. Keywords: complexity, design, innovation, life cycle, skill, system thinking | |||

| Vulnerable users safety is an important issue in terms of public health:
Most of these accidents involving truck and vulnerable user in urban areas has
tragic consequences for user and implicates trucks presence in urban areas. The
VIVRE2 project (ANR05-PDIT) took as its objective the study and design of
technological solutions for significantly reducing the number of these
accidents.
Around the truck driving simulator of RENAULT TRUCKS, designers, psychologists and ergonomists (LESCOT/INRETS and LEACM/University of Lyon2) specified strategies of driver assistance according to critical situations and Man Machine Interface. A tool for designing assistance systems has been specified and applied to the detection of vulnerable users in order to assess the relevance and efficiency of a homogeneous system for the whole identified situations. The designed system was evolved on the dynamical driving simulator. This paper presents the method for designing a driver assistance system, from contextual analysis to specification of HMI and strategies of assistance.

| Evolution des pratiques en conception: une approche ergonomique compréhensive des objets médiateurs | | BIBAK | Full-Text | 147-152 | |
| Catherine Elsen; Françoise Darses; Pierre Leclercq | |||
| This paper studies the evolution and modulation of "mediating objects'" use
in industrial design since the introduction of CAD (Computer Aided Design)
tools. These tools have generally been studied for their pros and cons inside
the design process, and always in comparison with more "traditional" tools
(freehand sketches or physical models) [9; 5]. The paper suggests rather to
consider these mediating tools' complementarities, that can sometimes occur
very early inside the design process (since ideation). The theoretical bases
that structure the whole intervention are presented and discussed given this
suggestion, as well as the in situ intervention's main results. The new
professional work-habits are objectivised. Keywords: ergonomics, evolution of industrial design practices, mediating objects | |||

| Corinne Grosse; Flore Barcellini | |||
| This communication concerns an intervention in a distributed team of a
computer science enterprise. Its objective was to prevent misunderstandings
that can occur within the collective. We are interested to misunderstandings
related to the design meetings, and the meeting's minutes associated as
memories of meetings and as a way to prevent misunderstandings. We found that 1
to 5% of the meeting is included in the minutes and that some issues still not
finalized or confidential are not included in the meeting's minutes.
Furthermore, we show that not logged information cannot be heard by the
co-designers: 20 to 100% of them attend the meeting with their laptop and work
on other tasks in parallel. We propose some organizational recommendations
(format of the minutes, temporal organization of the meeting) to overcome these
difficulties. Keywords: collaborative meetings, collective conception, communication,

| Creativity as a tool for prospective use analysis in the design of innovative products | | BIBAK | Full-Text | 162-169 | |
| Julien Nelson; Stéphanie Buisine; Améziane Aoussat | |||
| Ergonomists' participation to New Product Development (NPD) projects has
undergone major evolutions in recent years. One consequence is the changing
status of the ergonomist, from an expert in diagnosing existing activities, to
an expert in identifying opportunities in the use of a new product, with a need
for new methods and tools to assist prospective analysis of future use. We
propose an original approach to address this need of designers in general and
ergonomists in particular. We first present a survey of issues regarding
ergonomics involvement in NPD projects. We then argue that creativity methods
may be used to address some of these issues. Lastly, we describe a protocol to
test this claim, assessing the benefits of two creativity methods --
brainwriting and discovery matrices -- for prospective use analysis, with two
different applications: the design of products based on emerging technologies,
and that of safety systems. Keywords: creativity, innovation processes, prospective ergonomics, use analysis | |||

| Designing the next generation fighter aircraft requires more than just a
techno centered capability approach. This study offers an exploratory
anthropocentric research aiming at establishing the fundamental principles of
an aircraft architecture that would put its operator in optimal conditions to
make the right decisions.
As future missions become more and more complex and because the process timeframe keeps getting shorter, when analyzing the cognitive mechanisms, the possibility to share the decision authority between the human and the machine has to be envisaged. Crewmembers interviews allowed to identify and to flight simulate improvement opportunities. The first results yield a sensible reduction in the feeling of stress due to difficulty leading to overload and an increased serenity thanks to a better anticipation gained with automatic functioning. Moreover, the progress in measuring physiological changes could make the transfer more seamless when sharing the load, still considered with a unique artificial intelligence approach.

| The Project "Customer Service Area" (Espace Service Client -- ESC),
currently implemented in post offices, resulting in a new configuration of
working positions in "Ilots" now involves the position of standing work for the
clerks, both for traditional activities (sending mail) or new (management of
"boutique" sale of postal products, regional products, telephony, ...). With a
view to preventing risks in the health and safety at work, an ergonomic support
was created from feedback experiments conducted in the first twenty tests ESC
offices equipped with furniture derived from those existing in current offices.
Given the results, it was necessary to design specific furniture for different
"Ilots" that were then validated through user testing. Other recommendations
have also been developed for the management of workspaces, the choice of
different furniture, and the establishment of frequent rotations on different
working positions, to prevent risks in terms of health older staff. Keywords: ergonomic support, furniture ergonomics, health, risk prevention,

organization's usual individual work into a new cooperative work development,
managing multiple demands of customers, and learning sales techniques. To
better understand the human impact of these changes and the nature of
requirements for the personnel of company, semi-structured interviews were
conducted with 31 employees of French Post Office. The results obtained from a

| E-government services are actually a major stake for public administrations.
However, regarding perceived quality, no models, neither measurement scales are
specifically developed for them. A literature review, from a critical point of
view, leads to the conclusion that actual perceived quality models are not
taking enough into account end-users. This is mainly related to the methodology
approaches used for their definition. In order to overcome theses weaknesses,
we propose a methodology which aims at developing a measurement scale through
an ergonomic approach. This measurement scale will lead to the identification
of a perceived quality meta-model which could be instantiated to several
sub-models according to users' profile. Finally, we put forward application
perspectives to adaptive interfaces design. Keywords: adaptive interfaces, e-citizen, e-government, e-services, methodology,

| Jean-René Ruault; Claude Pourcel | |||
| Marketing, human factors and systems engineering are different disciplines
which apply different profiles and skills. Marketing is taught by business
schools, while very few engineering schools teach it. The latter dedicate much
time to systems engineering and many others engineering's. Human factors is
anchored within medicine, humanities and social sciences. It is a little part
of an engineer curriculum, while, since few years, human factors and
human-computer interaction are taught within engineering schools. Nowadays,
conferences and volunteers meet human factors and systems engineering, such as
ErgoIA (ErgoIA 2004, ErgoIA 2006, ErgoIA 2008 [22]) or AFIS' human factors
technical committee.
The aim of this article is to show complementarily between these disciplines to design systems which satisfy consumers and users' needs, particularly in the business to consumer context. At first this article presents main processes of these disciplines and how these processes should be coordinated together. Then, it demonstrates how marketing and human factors processes' outputs structure system architecture design. This article finishes with a case study applying the proposed approach, in the domain of health and care service systems.
