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 ...

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 ...

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 ...

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 ...

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 ...

This article describes our first experiments in BCI (Brain Computer Interface) and HCI (Human Computer Interaction). Through three case studies on two different BCI headsets (NIA and EPOC), we show the pro and cons of these devices about their ...

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 ...

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 ...

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 ...

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. ...

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 ...

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 ...

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 ...

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: ...

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 ...

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-...

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-...

As part of research in teaching of science, we are interested in the innovative potential of mobile technologies. We present the theoretical fondamentals on which we base our research and we summarize two exploratory case studies: one for collaborative ...

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 ...

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 ...

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 ...

This article describes the practice of the ergonomists of the group FT Orange working in the Customers Test Center of Rennes. It resumes the usual methods to evaluate the utilisability of products and services according to the criteria of the Standard ...

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 ...

This paper describes an epidemiologic study on difficulties of use, observed during cockpit design assessment campaigns. Design a product requires to anticipate, to envisage the future modes of use, to test them and provide solutions in term of ...

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 ...

The restructuring of French post offices in "Espace Service Client" -- ESC - ("Customer Service Area"), currently underway, includes multifunction booths, a "store" for postal products and also regional produce, and booths for banking. These structural ...

In Thanks to ambient computing, information can be diffused and accessed everywhere, at anytime, on any platform. But how worthwhile is this for citizens? Is their quality of life improved? This article describes the application of the Worth Centered ...

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 ...

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 ...
