Conception rapide d'aides techniques pour personnes tétraplégiques

International audienceLes aides techniques permettent à de nombreuses personnes tétraplégiques d'accomplir des tâches qu'elles ne pourraient pas accomplir sans elles. Selon (Laffont, 2008), la possibilité de contrôler son environnement est d'ailleurs déterminante pour la qualité de la réinsertion sociale, familiale et professionnelle. En parallèle, nous pouvons constater qu'une grande proportion des aides techniques disponibles est peu ou pas utilisée. Ceci qui s'expliquer par de multiples raisons : manque d'écoute dans la sélection, difficulté d'obtention des aides techniques, des performances et du changement de besoins. Néanmoins, le développement récent de technologies à très bas coût, l'engouement du public pour le Do It Yourself et la diffusion des connaissances en interaction homme-machine permettent d'affirmer qu'il est possible de concevoir rapidement des aides techniques réellement adaptées. Nous illustrerons ces aspects au travers d'expériences menées de la conception à la réalisation de prototypes matériel et logiciels pour personnes tétraplégique

Internet : du rêve du partage généralisé à la nécessaire sécurité

Concomitamment aux facilités qu'offrent les moyens technologiques récents, la question de la cybercriminalité se pose dans de nouvelles dimensions et des termes qui, par bien des aspects, peuvent paraître très inquiétants. De simples outils facilement accessibles sur Internet permettent à des néophytes de paralyser des sites web, de "casser" des mots de passe ou des clés de cryptage wifi, facilitant ainsi l'intrusion et donnant accès à des données sensibles ou de capturer et modifier à la volée des données transitant sur le réseau. Ces attaques suivent le plus souvent une stratégie "globale" mêlant à la fois technique et ciblage d'information. L'émergence des réseaux sociaux facilitant le ciblage des utilisateurs, personne n'est plus à l'abri : particuliers, laboratoires de Recherche & Développement, administrations, grandes entreprises mais aussi et surtout les PME et ETI. Quelles sont les menaces réelles ou supposées ? Quelles sont les techniques utilisées ? Qui sont les acteurs et les cibles ? Quelle riposte technique et juridique peut-on proposer pour s'en prémunir ? Telles sont les questions abordées dans cet article

Un cadre de conception centré utilisateur pour les systèmes de biofeedback

International audienceBiofeedback is defined as a technique that you can use to learn how to control the functions of your body. In essence, biofeedback gives you the power to use your physiological data to control your body, used frequently to improve a state of health or physical performance. We present in this article a summary of the components of the architecture of biofeedback systems based on literature. Then we offer a complete design framework to allow help to design systems with biofeedback.Le biofeedback est défini comme une technique que vous pouvez utiliser pour apprendre à contrôler les fonctions de votre corps. En substance, le biofeedback vous donne le pouvoir d’utiliser vos données physiologiques pour contrôler votre corps, souvent pour améliorer un état de santé ou de la performance physique.

Ensuite, nous proposons un cadre complet de conception pour permettre d’aider à la conception de systèmes avec biofeedback

Design and evaluation of Multi-function Scanning System : a case study

International audienceWe present in this paper an assistive technology of communication and command for quadriplegics. To carry out this assistive technology, a user centered design approach with the patient, his occupational therapists and his family was conducted. Various iterative versions of the prototype have been defined by means of the SOKEYTO platform to meet the needs and the abilities of the quadriplegic person. Options carried out and consecutive choice will be reported as well the difficulties to implement. The assistive technology was used by one quadriplegic person. A qualitative evaluation is also reported

Fisheye keyboard : whole keyboard displayed on small device

In this article, we propose a soft keyboard with interaction inspired by research on visualisation information. Our goal is to find a compromise between readability and usability on a whole character layout for an Ultra mobile PC. The proposed interactions allow to display all keys on a small screen while making pointing easier for the user by expanding any given key as a function of its distance from the stylus

Usage of multimodal maps for blind people: why and how

International audienceMultimodal interactive maps are a solution for providing the blind with access to geographic information. Current projects use a tactile map set down on a monotouch display with additional sound output. In our current project we investigated the usage of multitouch displays for this purpose. In this paper, we outline our requirements concerning the appropriate multitouch tactile device and we present a first prototype. We conclude with future working propositions

Ysilex : a Friendly reading Interface for Dyslexics

International audienceIn this paper, we describe an interface to display texts in a fashion adapted to dyslexic readers. In order to help the reading task, we designed several tools geared towards the specific difficulties of this population, e.g. a tendency to lose one's place within the text, a fluctuating attention or a difficulty to access the syllable level of the words, a process known to be used with new or infrequent words. Preliminary results show that a pared down display coupled with a choice of tools available on demand could cater to the heterogeneity of difficulties displayed by dyslexics. Stepwise increments in design coupled with ongoing validation of the reading tools will insure the usefulness of the interface

Map design for visually impaired people: past, present, and future research

International audienceOrientation and mobility are amongst the most important challenges for visually impaired people. Tactile maps can provide them with spatial knowledge of their environment, thereby reducing fear related to travelling in space. To date, raised-line paper maps have been used to make geographic information accessible, but these paper maps have significant limitations with regards to content and the presentation of information. Recent advances in technology may help to design usable interactive maps that overcome such limitations. In this paper, we first review different accessible map concepts. We then present our design of an interactive map prototype, and provide evidence of this interactive map’s high user satisfaction and efficiency as compared to a regular raised-line paper map. To conclude, we suggest that advances in interactive technologies (e.g., haptic touch surfaces) provide a unique opportunity to design usable maps in the near future

Co-design of the Medical Assistive and Transactional Technologies system

National audienceThis paper could argue that the co-design method is strongly needed to design acceptable and usable assistive technologies. It describes the co-design of the Medical Assistive and Transactional Technologies (MATT) system. This method was implemented for Matthieu a quadriplegic and a non verbal person. The paper reports how the collaborative design was running between Matthieu, his occupational therapists, his family and the designer team

A method story about brainstorming with visually impaired people for designing an accessible route calculation system

In this paper we describe a brainstorming session with visually impaired users, a sighted locomotion trainer, as well as sighted and blind researchers. This brainstorming session was part of a larger project on designing accessible guidance systems for visually impaired people. In this session we specifically addressed the design of an accessible route calculation tool. In a method story, we describe how this session took place and report our insights from this experience on adapting brainstorming to a non-visual world
