Tabletop computers cannot become larger than arm’s length without giving up direct touch. This prevents tabletop applications from dealing with more than a few dozen on-screen objects. We propose direct touch surfaces that are orders of magnitude larger by integrating high-resolution multi-touch into back-projected floors, while maintaining the purpose and interaction concepts of tabletop, i.e., direct manipulation.

We based our design on frustrated total internal reflection because its ability to sense pressure allows the device to see users’ soles when applied to a floor. We demonstrate how this allows us to recognize foot postures and to identify users. These two functions form the basis of our system. They allow the floor to ignore inactive users, identify and track users based on their shoes, enable high-precision interaction, invoke menus, as well as track heads and allow users to control several multiple degrees of freedom by balancing their feet.

C’est une technologie très intéressante.  Maintenant, nous pouvons utiliser l’ordinateur par les orteils au lieu de les mains. Probablement, nous devrions pratiquer dancer pour la future proche. Imaginez, un jour, nous devons entrer les codes ou dancer quelque pas avant entrer notre maison ou bureau.  Très cute nous somme.

Cloud Computing – The next generation

Cloud Computing

Definition:(from wikipedia)

Cloud computing is Internet-based computing, whereby shared resources, software and information are provided to computers and other devices on-demand, like a public utility.

It is a paradigm shift following the shift from mainframe to client-server that preceded it in the early ’80s. Details are abstracted from the users who no longer have need of, expertise in, or control over the technology infrastructure « in the cloud » that supports them. Cloud computing describes a new supplement, consumption and delivery model for IT services based on the Internet, and it typically involves the provision of dynamically scalable and often virtualized resources as a service over the Internet. It is a byproduct and consequence of the ease-of-access to remote computing sites provided by the Internet.

The term cloud is used as a metaphor for the Internet, based on the cloud drawing used in the past to represent the telephone network, and later to depict the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents. Typical cloud computing providers deliver common business applications online which are accessed from another web service or software like a web browser, while the software and data are stored on servers.

A technical definition is « a computing capability that provides an abstraction between the computing resource and its underlying technical architecture (e.g., servers, storage, networks), enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. »[7] This definition states that clouds have five essential characteristics: on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service.

The majority of cloud computing infrastructure, as of 2009[update], consists of reliable services delivered through data centers and built on servers. Clouds often appear as single points of access for all consumers’ computing needs. Commercial offerings are generally expected to meet quality of service requirements of customers and typically offer SLAs.

Si l’on considère la naissance de l’ordinateur personnel est la première révolution de la technologie numérique, et la naissance d’Internet est la seconde, puis la naissance du cloud computing est le troisième. Avant longtemps, nous n’aurons pas à installer quoi que ce soit dans notre système du ordinateur parce que tout les logiciel serais dans le « cloud ». La seule chose que nous avons besoin est un accès à Internet. La étude scientifique qui nécessite une puissance de calcul super va être possible avec la technologie du cloud computing.

Cette technologie va changer notre façon de vivre
