“…Néanmoins, la plupart des systèmes existants employant la vision [7,8] demeurent sensibles à l'illumination, les rendant inutilisables en extérieur. Pour pallier ces défauts, nous employons des algorithmes de traitement d'image robustes, s'adaptant automatiquement aux conditions lumineuses [2]. Nos caméras sont situées derrière la surface, de manière à ce qu'elles soient discrètes, non accessibles et qu'elles ne nécessitent pas de percer la surface pour y faire passer des câbles.…”

RESUMEDans cette démonstration, nous présentons une nouvelle génération de kiosque interactif intégré, multipoints et réagissant à la présence de personnes, destiné à l'usage dans un espace public. Les systèmes interactifs publics existants n'offrent qu'une interaction très spécifique, ce qui limite leur utilité, leur utilisabilité et leur attractivité. Pour résoudre ces défauts, nous proposons une solution de tactilisation fluide et de perception du contexte fondée sur la vision par ordinateur. Nous couplons cette perception à une boîte à outils de construction de systèmes interactifs, inspirée des architectures à agents PAC. Une application interactive est décrite de manière similaire à une application web (ressources XML, asynchrone, CSS, et un langage similaire à JavaScript). Le rendu graphique est effectué par le canevas GML. Des installations commerciales montrent que les utilisateurs naïfs s'approprient et utilisent notre kiosque. ABSTRACTIn this demo, we present a new integrated, multi-touch and presence-aware kiosk, designed for public spaces. Existing public interactive systems offer limited interactions, which hinders their utility, usability and attractivity. To overcome these obstacles, we propose a computer vision-based approach to fluid tactilisation and context perception. This is coupled with an interaction toolkit inspired from PAC agents achitectures. An interactive application is described much like a web application-using asynchronous XML, CSS, and a Javascriptlike language. GUI rendering performance is achieved by using the OpenGL-based canvas GML. Commercial installations show that naive users appropriate and use our kiosk.

“…This constraint is one of the main differences between remote experimentation and other realtime applications such as video-streaming. Human eyes will notice a delay larger than 50 ms [21], similarly a delay larger than 200 ms is noticeable in audio transmission [22]. While these values express minimum values, a delay smaller than a second is noticeable by the user, albeit acceptable since it is short enough to avoid any inappropriate sensorimotor reaction from the user [23].…”

Remote experimentation is an effective e-learning paradigm for supporting hands-on education using laboratory equipment at distance. The current trend is to enable remote experimentation in mobile and ubiquitous learning. In such a context, the remote experimentation software should enable effective telemonitoring and teleoperation, no matter the kind of device used to access the equipment. It should also be sufficiently lenient so as to handle the rapidly evolving wireless and mobile communication environment. While the current Internet bandwidth allows remote experimentation to work flawlessly on fixed connections such as LANs, mobile users suffer from both the versatile nature of wireless communications and the limitation of the mobile devices. These conditions impose that the remote experimentation software should integrate adaptation features. For effective ubiquitous remote experimentation, it should ideally be guaranteed that the information representing the state of the remote equipment is rendered (to the end user) at the same pace at which it has been acquired, yet possibly at the cost of a somewhat minimal time delay between the acquisition and rendering phases. In this respect, an end-to-end adaptation scheme is proposed that explicitly handles the inherent variability of the connection and the versatility of the mobile devices considered in ubiquitous remote experimentation. Instead of relying on a stochastic approach, the proposed adaptation scheme relies on a deterministic mass-balance equivalence model. The effectiveness of the proposed adaptation scheme is demonstrated in critical conditions corresponding to remote experimentation carried out using a PDA over a Bluetooth link.
