Accessibility to textual and visual information on websites for visually impaired personsKaterine Romeo, Edwige Pissaloux, Frédéric Serin
Access to textual and visual information for visually impaired persons becomes very difficult with screen readers which are not adapted to different websites.This paper analyses the use of different technologies for access digital content and to establish some ameliorations to the existing recommendations to accessible website conception for all. The preliminary evaluation results with visually impaired people of our website ACCESSPACE which is constructed with the existing recommendations, confirm the project's relevance.

Accessibility of websites for visually impaired personsKaterine Romeo, Edwige Pissaloux, Frédéric Serin
Accessibility of websites for visually impaired persons is mishandled by screen readers which are not always adapted to interactivity needed by actual web/multimedia technologies. This paper analyses the difficulties to access to information with the use of different technologies and the existing recommendations for the conception of accessible websites for all. Preliminary results with visually impaired persons on our ACCESSPACE project website are presented.

Towards a Multiagent Decision Support System for crisis ManagementFahem Kebair, Frédéric Serin
Crisis management is a complex problem raised by the scientific community currently. Decision support systems are a suitable solution for such issues, they are indeed able to help emergency managers to prevent and to manage crisis in emergency situations. However, they should be enough flexible and adaptive in order to be reliable to solve complex problems that are plunged in dynamic and unpredictable environments. The approach we propose in this paper addresses this challenge. We expose here a modelling of information for an emergency environment and an architecture of a multiagent decision support system that deals with these information in order to prevent and to manage the occur of a crisis in emergency situations. We focus on the first level of the system mechanism which intends to perceive and to reflect the evolution of the current situation. The general approach and experimentations are provided here.
