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.

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.

Intel InfoScape Double HD Touchscreen Internet Experience

We hate to dampen your excitement right from the get-go, but Intel confessed that it has absolutely no plans of commercializing something like this itself — but that’s not to say someone else couldn’t grab a Core i7 and run with the idea themselves. The Infoscape was generating quite a bit of attention at the chip giant’s CES booth, boasting twin 7-foot touch panels (each with a 1,920 x 1,920 resolution). The entire installation was powered by a single Core i7-based machine with Intel’s own graphics, and it was seen rendering 576 links of live information. Users could touch any individual panel in order to dig deeper and bring up more information on each link, and it had absolutely no trouble pulling up dozens of boxes at once when legions of onlookers decided to touch boxes simultaneously. Hop on past the break to check out a video, and feel free to drop your wildest ideas of where this could be used (like, your den) in comments below.

C’est une démo de the Core i7 processor et une performance de la page visuelle. Le mur de l’écran creats le sentiment immersif. C’est la nouvelle application de l’écran de l’ordinateur et le nouveau concept de l’organisation de l’information.

An organic light emitting diode (OLED), also organic electro luminescent device (OELD), is a light-emitting diode (LED) whose emissive electroluminescent layer is composed of a film of organic compounds. This layer of organic semiconductor material is formed between two electrodes, where at least one of the electrodes is transparent.

Such devices can be used in television screens, computer monitors, small, portable system screens such as cell phones and PDAs, watches, advertising, information and indication. OLEDs can also be used in light sources for general space illumination, and large-area light-emitting elements. Due to the younger stage of development, OLEDs typically emit less light per unit area than inorganic solid-state based LEDs which are usually designed for use as point-light sources.

In the context of displays, OLEDs have certain advantages over traditional liquid crystal displays (LCDs). OLED displays do not require a backlight to function. Thus, they can display deep black levels and can be thinner and lighter than LCD panels. OLED displays also naturally achieve higher contrast ratios than either LCD screens using cold cathode fluorescent lamps (CCFLs) or the more recently developed LED backlights in conditions of low ambient light such as dark rooms.


The different manufacturing process of OLEDs lends itself to several advantages over flat-panel displays made with LCD technology.

Although the method is not currently commercially viable for mass production, OLEDs can be printed onto any suitable substrate using an inkjet printer or even screen printing technologies,[45] they could theoretically have a lower cost than LCDs or plasma displays. However, it is the fabrication of the substrate that is the most complex and expensive process in the production of a TFT LCD, so any savings offered by printing the pixels is easily cancelled out by OLED’s requirement to use a more costly P-Si (or LTPS) substrate – a fact that is born out by the significantly higher initial price of AMOLED displays than their TFT LCD competitors. A mitigating factor to this price differential going into the future is the cost of retooling existing lines to produce AMOLED displays over LCDs to take advantage of the economies of scale afforded by mass production.

Use of flexible substrates could open the door to new applications such as roll-up displays and displays embedded in fabrics or clothing.

OLEDs can enable a greater artificial contrast ratio (both dynamic range and static, measured in purely dark conditions) and viewing angle compared to LCDs because OLED pixels directly emit light. OLED pixel colours appear correct and unshifted, even as the viewing angle approaches 90 degrees from normal. LCDs filter the light emitted from a backlight, allowing a small fraction of light through so they cannot show true black, while an inactive OLED element produces no light and consumes no power.

OLEDs can also have a faster response time than standard LCD screens. Whereas LCD displays are capable of a 1ms response time or less[46] offering a frame rate of 1,000 Hz or higher, an OLED can theoretically have less than 0.01 ms response time enabling 100,000 Hz refresh rates.

Technology demos

In May 2007, Sony publicly unveiled a video of a 2.5-inch flexible OLED screen which is only 0.3 millimeters thick.

On May 24, Sony unveiled what it is calling the world’s first flexible, full-color organic light emitting diode (OLED) display built on organic thin-film transistor (TFT) technology. OLEDs typically use a glass substrate, but Sony researchers developed new technology for forming organic TFT on a plastic substrate, enabling them to create a thin, lightweight and flexible full-color display. The 2.5-inch prototype display supports 16.8 million colors at a 120 x 160 pixel resolution (80 ppi, .318-mm pixel pitch), is 0.3 mm thick and weighs 1.5 grams without the driver.

According to Sony, which plans to release a new line of miniature TVs this year and is bolstering efforts to develop next-generation flat-panel OLEDs, this new technology will lead to the development of thinner, lighter and softer electronics.

The company is scheduled to present the results of its research at the SID 2007 International Symposium now underway in the US.

Samsung’s 14-inch transparent OLED laptop

If you thought the XPERIA Pureness was wild with its meager 1.8-inch transparent screen, wait’ll you get a hold of Samsung Mobile Display’s prototype 14-inch notebook — complete with what’s being touted as the world’s first and largest transparent OLED prototype. When the thing is off, the panel is up to 40 percent transparent (as opposed to the industry average of below twenty-five percent). Not much more to say about it (we’ll let you know as soon as our friends from Korea tell us more), but there is plenty to see: so get a load of the video after the break.

Sony OLED 3D TV eyes-on

Sony is showing off its 24.5-inch OLED television here at CES, and we have to admit to being blown away once more by the sheer vibrancy and clarity of the output. The jump from the 15-inch panels that are still very sparsely available in retail channels is most welcome. We can totally envision spending our happily ever after with one of these screens serving all of our visual needs, 3D or otherwise. Sony’s reps couldn’t tell us when these will make it to market, but the pics below should whet appetites appropriately.

Avec tous les avantages de la technologie d’affichage OLED, elle va prendre possession de le marché de l’écran mince dans quelques années et il y aura plus de nouvelles applications de cette technologie. Il y aura moins la limitation de l’écran dans la forme, l’aspect et le poids.

Headquartered in Calgary, Alberta, Immersive Media Corp. has two wholly owned subsidiaries: Immersive Media Company in Portland, Oregon, and IMC Sensors (DBA Immersive Security) in Dallas, Texas. Immersive Media Corp. is a publicly traded company on Canada’s TSX Venture Exchange under the stock symbol “IMC.”

David McCutchen, Immersive Media’s Chief Technical Officer, was working in the special effects industry in the 1980s when he started searching for a camera system that could capture wraparound images. When he found that no such system existed, McCutchen used the principles of geodesic design to develop the technology himself. He applied for a patent in 1989, it was issued in 1991 and Immersive Media was formed three years later.

Since 1994, Immersive Media has been the world leader in 360°, full motion, interactive videos. The Dodeca® 2360 camera system, Immersive Media’s flagship product, is currently in fourth-generation hardware. The company maintains ongoing development of new camera and software platforms, with a patent portfolio covering key discoveries and capabilities of interactive and immersive video.

Microsoft Courier tablet n’est pas un concurrent de l’iPad!


Microsoft était prêt à sortir une Tablet qui s’appelle la Courier. Beaucoup de personne comparent la Courier avec l’ipad de Apple, mais il n’est pas un concurrent de l’iPad! Parce que je pense que la Courier de Microsoft intéresse un marché vraiment different avec l’ipad.

L’ipad est une « Tablet », mais Courier de Microsoft est une « Booklet », et il est plus comme un livre ou un agenda. I’ipad est plus fort dans le divertissement(mais il ne supporte pas du flash).   La Courier est très puissante fonctionnalité sur le management quotidien et lire des ebooks ou documents( presque comme lire un liver de papier). Certainement, il posséde les autres fonctions, vous pouvez regarder sa video.

En fait que, je vais choisir la Courier de Microsoft pour lire des livres, et l’Ipad pour jouer. Si je ne peut pas avoir les deux en même temps, je prefere la Courier.

Caractéristiques techniques du Courier:
Ecran : multitouch 7″ tactile (fonctionne aussi avec un stylet inclus)
Processeur : Tegra 2 de NVidia
OS : Windows CE 6
Caméra 3MP

(Suivant à partir de

Le monde entier retient son souffle en attendant l’arrivée de la tablette Apple. Mais peut-être avons-nous tous rêvé du mauvais appareil.

Voici Courier, la stupéfiante interprétation de la tablette par Microsoft.

Courier est un véritable appareil, et nous avons appris que son développement en est au stade du “prototype avancé”. Ce n’est pas une tablette, c’est un livret. Les deux écrans 7 pouces (environ) sont mutitouch, et conçus pour pouvoir écrire et dessiner avec un stylet en plus d’être touchés avec les doigts. Ils sont reliés par une charnière dotée d’un seul bouton home iPhonesque.

Les voyants d’état pour la connexion sans fil et la batterie sont disposés dans le cadre d’un des écrans. Courier est équipé au dos d’une caméra et peut se recharger sans fil sur un tapis inductif, comme le dock de rechargement Touchstone du Palm Pre.

Jusqu’à récemment, c’était un obscur travail de recherche mené dans un coin chez Microsoft, connu de seulement quelques ingénieurs et cadres qui travaillaient dessus. Le projet était chapeauté par leur sorcier de l’expérience utilisateur et chef de la technologie de la division Entertainment & Devices, J. Allard. A l’heure actuelle, Courier semble en être à une étape où Microsoft développe l’expérience utilisateur et montre des concepts de designs à des agences externes.

Microsoft a un historique de collaboration avec d’autres entreprises, en particulier dans la division E&D: Zune et Xbox ont été développés selon ce même procédé. La vidéo est signée Pioneer Studios, une entité de Microsoft au sein de la division E&D qui est spécialisée dans ce genre de boulot, travaillant avec une autre agence qui est un partenaire de longue date de Microsoft pour les projets secrets.

L’expérience utilisateur de Courier présentée ici est presque l’exact contraire de ce que tout le monde attend de la tablette Apple, des serres d’aigle de kung fu en réponse au style tigré d’Apple. Deux écrans, un mélange d’interactions au stylet avec plusieurs types de gestes multitouch, et des thèmes graphiques complexes et multiples. Cette tablette Microsoft revendique un héritage de livre électronique et propose plusieurs manières intéressantes d’interagir avec les données.

Restez dans les parages, car nous approfondirons ces prochains jours le sujet de la tablette Courier.

MOOG MUSIC Etherwave Theremin


l’introduction du produit

The theremin is one of the oldest electronic instruments, and the only one known that you play without touching. Moving your hands in the space around its antennas controls pitch and volume. The Etherwave is an authentic adaptation of inventor Lev Termen’s original design.

The Etherwave is a quality musical instrument designed for ruggedness and portability. It has a five-octave pitch range and reliable spacing between notes for sophisticated playability. Antennas are nickel-plated 3/8″ brass tube and cabinets are furniture-grade hardwood, finished with a custom Moog stain. The Etherwave is fitted with an adapter for mounting on a standard microphone stand and works best with Moog’s TB-15 instrument amplifier.


L’histoire de la technologie theremin

The theremin was originally the product of Russian government-sponsored research into proximity sensors. The instrument was invented by a young Russian physicist named Lev Sergeivich Termen (known in the West as Léon Theremin) in October 1920 after the outbreak of the Russian civil war. After positive reviews at Moscow electronics conferences, Theremin demonstrated the device to Bolshevik leader Vladimir Lenin. Lenin was so impressed with the device that he began taking lessons in playing it, commissioned six hundred of the instruments for distribution throughout the Soviet Union, and sent Theremin on a trip around the world to demonstrate the latest Soviet technology and the invention of electronic music. After a lengthy tour of Europe, during which time he demonstrated his invention to packed houses, Theremin found his way to the United States, where he patented his invention in 1928 (US1661058). Subsequently, Theremin granted commercial production rights to RCA.

Although the RCA Thereminvox (released immediately following the Stock Market Crash of 1929), was not a commercial success, it fascinated audiences in America and abroad. Clara Rockmore, a well-known thereminist, toured to wide acclaim, performing a classical repertoire in concert halls around the United States, often sharing the bill with Paul Robeson. In 1938, Theremin left the United States, though the circumstances related to his departure are in dispute. Many accounts claim he was taken from his New York City apartment by KGB agents,[4] taken back to the Soviet Union and made to work in a sharashka laboratory prison camp at Magadan, Siberia. He reappeared 30 years later. In his 2000 biography of the inventor, Theremin: Ether Music and Espionage, Albert Glinsky suggested the Russian had fled to escape crushing personal debts, and was then caught up in Stalin’s political purges. In any case, Theremin did not return to the United States until 1991.[5]

Today Moog Music, Dan Burns of[7] Chuck Collins of[7] Wavefront Technologies, Kees Enkelaar[8] and Harrison Instruments manufacture performance-quality theremins. Theremin kit building remains popular with electronics buffs; kits are available from Moog Music, Theremaniacs, Harrison Instruments, PAiA Electronics, and Jaycar. On the other end of the scale, many low-end Theremins, some of which have only pitch control, are offered online and offline, sometimes advertised as toys.


The theremin is unique among musical instruments in that it is played without physical contact. The musician stands in front of the instrument and moves his or her hands in the proximity of two metal antennas. The distance from one antenna determines frequency (pitch), and the distance from the other controls amplitude (volume). Most frequently, the right hand controls the pitch and the left controls the volume, although some performers reverse this arrangement. Some low-cost theremins use a conventional, knob operated volume control and have only the pitch antenna.

The theremin uses the heterodyne principle to generate an audio signal. The instrument’s pitch circuitry includes two radio frequency oscillators. One oscillator operates at a fixed frequency. The frequency of the other oscillator is controlled by the performer’s distance from the pitch control antenna. The performer’s hand acts as the grounded plate (the performer’s body being the connection to ground) of a variable capacitor in an L-C (inductance-capacitance) circuit. The difference between the frequencies of the two oscillators at each moment allows the creation of a difference tone in the audio frequency range, resulting in audio signals that are amplified and sent to a loudspeaker.

To control volume, the performer’s other hand acts as the grounded plate of another variable capacitor. In this case, the capacitor detunes another oscillator, which affects the amplifier circuit. The distance between the performer’s hand and the volume control antenna determines the capacitor’s value, which regulates the theremin’s volume.[9]

Modern circuit designs often simplify this circuit and avoid the complexity of two heterodyne oscillators by having a single pitch oscillator, akin to the original theremin’s volume circuit. This approach is usually less stable and cannot generate the low frequencies that a heterodyne oscillator can. Better designs (e.g. Moog, Theremax) may use two pairs of heterodyne oscillators, for both pitch and volume.



Je crois que la plupart des gens pensent qu’un homme doit au moins toucher à son instrument pour faire de la musique. C’est vrai pour la plupart des cas, mais pas pour Etherwave. Etherwave theremin est un produit de Moog Music. Il n’a pas de clavier, pas des cordes, meme pas une place qui semble etre touche. C’est simplement une petite boîte qui a deux antennes. Par simplement en déplaçant les mains en l’air autour des antennes, on peut faire de la musique. Non seulement vous pouvez contrôler le volume et la hauteur, vous pouvez également contrôler les paramètres comme  la fréquence du filtre, etc.

Cette technologie a déjà été utilisé dans le domaine des pratiques comme la musique électronique, le design sonore, et musique de film. Vous pouvez entendre le son de celui-ci dans la musique originale du film <the day the earth stood still>, <the sign> et <Black hawk down>.
