Smart eyewear is defined as eyewear incorporating a near-to-eye display. As used herein, near-to-eye display means a display, device, or system, such as a retinal projector, virtual retinal display, visualization element, head-mounted display, heads-up display, or other near-to-eye system, typically worn on the head of a user that generates an image near the eye. In a smart eyewear configuration, a display device is often mounted adjacent to an edge of each of the wearer's eyes and an image is typically displayed in the center of each lens. The location of the displayed image, therefore, forces the wearer to gaze in a direction to view the image generated by the display. Typically positioned near the user's eye, the display is aligned to the central region of the user's field of view to allow review of the displayed information with little or no head movement. This enables the user to view the display while also viewing the area outside the central region and interacting with the surrounding environment. In another embodiment, the displayed image is aligned to a region other than the central region of the user's field of view.

CONT

Near-eye display devices are configured to present images to a user via a display that is positioned close to the user’s eyes. For example, a head-mounted augmented reality display device may be worn on a user’s head to position a near-eye display directly in front of a user’s eyes. A near-eye display may be at least partially see-through to allow a user to view a real-world background in combination with displayed virtual objects. This may allow virtual objects to be displayed such that the virtual objects appear to exist within the real-world environment.

CONT

The technology provides one or more embodiments of a near-eye display (NED) device system. An embodiment of a NED device system comprises a near-eye display device including a near-eye support structure and a near-eye display (NED) supported by the near-eye support structure and having a display field of view. The NED system further comprises an image generation unit supported by the near-eye support structure which outputs image data which is optically coupled to the near-eye display (NED).

To maintain a stable perception of the world around us while we engage in normal movements throughout our day, such as walking, we have something known as the vestibulo-ocular reflex(VOR). This reflex keeps us steady and balanced even though our eyes and head are continuously moving when we perform most actions. When we make a head movement, our eye muscles are triggered instantly to create an eye movement opposite to that of our head movement at the exact same speed to readjust the visual world, which, in turn, stabilizes our retinal image by keeping the eye still in space and focused on an object, despite the head motion.

CONT

Atomic-force microscopy is similar to scanning-tunneling microscopy(STM) in that it can image surfaces at atomic-scale resolution. The difference between AFM and STM is that AFM does not require that the sample be an electrically conducting material. Like STM, it uses an atomically-sharp tip that is brought very close to the surface. The tip will feel a chemical attraction or repulsion and will move up or down on its supporting cantilever. This movement is monitored by an optical laser beam as the tip is moved laterally across the surface. As in STM, rastering the tip across the surface produces a topographic map of the surface.

DEF

Microscopie à sonde locale qui utilise la mesure des variations des forces attractives et répulsives s'exerçant entre les atomes de la pointe de la sonde et ceux de la surface de l'échantillon.

CONT

La microscopie à force atomique (AFM : «atomic force microscopy») a été introduite en 1986 par G. Binnig, C.F. Quate et C. Gerber, comme une application du concept de microscope à effet tunnel (STM : «scanning tunneling microscope») [...] permettant l'étude de surfaces de matériaux isolants à l'échelle atomique. En combinant les principes du microscope à effet tunnel et du stylet profilométrique, les auteurs démontraient la possibilité d'imager, à l'air libre, la surface d'échantillons conducteurs ou non, avec une résolution latérale de 30 Å [angström] et une résolution verticale inférieure à 1 Å. La technique a, depuis lors, été adaptée à différents environnements tels que le vide, le milieu liquide, les basses températures, les champs magnétiques et aussi pour des applications en chimie ou en biologie. L'AFM est basée sur la mesure des forces entre un fin stylet et la surface étudiée. Le capteur de force est un ressort-lame (stylet) encastré à une extrémité et muni d'une pointe à l'autre extrémité; il est encore appelé «cantilever». Les forces d'interaction modifient la déflection ou la torsion statique ou oscillante du stylet. La mesure des déformations du «cantilever» dans les microscopes de force actuels s'effectue, le plus souvent, grâce à la déviation d'un faisceau lumineux («diode laser») réfléchi par l'extrémité du stylet, méthode proposée dès 1988 par G. Meyer et N. Amer [...] La majorité des utilisateurs cherche à obtenir des formes ou des tailles caractéristiques de la surface; en balayant l'échantillon sous le «cantilever», on obtient l'image AFM recherchée. Mais on s'est très vite aperçu qu'il était possible avec le même instrument de proposer des situations originales de «physique au nanomètre».

Subject field(s)
  • Remote Sensing
DEF

A remote-sensing term referring to the process of assigning different colours to different spectral bands.

CONT

The image processing consisted in generating intensity images and one coherence image. To facilitate their analysis and interpretation, a coloured composition has been created with the results. This composition is obtained by adding the coherence image in red, the average of both images phase intensities in green and the difference between these phase intensities in blue. As such, a high coherence level(value close to 1) appears in red and indicates a very good phase correlation between the two images, a consequence of the various mechanisms of radar signal scattering and of the lack of change which could affect the target. On the contrary, a weak coherence level(value tending to 0) appears in black and indicates a movement in these zones during the 24 hours interval which separated the two image shots. Lastly, the white spots correspond to areas with a strong radar signal backscattering i. e. with zones of hills or vegetation.

In multimedia, a single film or video frame presented as a single, unmoving image.

CONT

Video compression is measured by four basic criteria : compression ratio, picture quality, compression and decompression speeds, and the hardware and software resources required to achieve it. Use of compression with motion video is mandatory, but it also benefits still images, particularly in multimedia applications where the end-user should not be left waiting for things to happen on the screen. Processing of a single image in one second or less is generally acceptable for a still picture, but motion video requires at least 15 fps to produce the effect of smooth movement.

... The large body [of the camera] accommodates an impressively long 12X zoom... The lens also includes an optical image stabilizer, which moves an element of the lens to keep images steady(other cameras include electronic image stabilization, which helps the camera compensate for movement after the image is taken; optical stabilization tends to be more effective).

Three classes of image movement can be recognised. The most obvious... is the steady movement due to the forward velocity of the aircraft. Next are the vibratory movements of the airframe excited by out-of-balance forces in the engines or airscrews, or by aerodynamic forces; some of this vibration always reaches the camera... The third... is the slow-period movement of the aircraft as a whole about its mean orientation in flight.... The effect of image movement on resolution has always been somewhat obscure, and it [is surprising] to find how much movement can be tolerated before its results appear as a blurring of the image.

"The resolution of a satellite image of the earth depends on the height of the satellite's orbit and the quality of the recording equipment, "says Steve Drury, an expert on satellite imaging. "The lower the orbit and the better the equipment, the clearer and more detailed the image will be. But every image is affected by atmospheric shimmer, caused by the movement of hot and cold currents of air in the atmosphere. Because different air currents have different refractive indices, the light travelling through them is bent slightly, so the image that the satellite receives is out of focus and blurred. "The most obvious effect of atmospheric shimmer(or turbulence) that we can see from earth is the twinkling of stars. Light from stars is blurred as it passes through the earth's atmosphere.

Another new class of testing tool allows engineers to observe patterns of stress and strain on a spinning disc. Pulsed-laser holography, one of these new methods, uses rapid sequences of holographic "snapshots" to create holograms which can show minute surface distortions caused by vibration. An optical "derotator", consisting of a prism rotating at half the speed of the specimen, freezes the movement of the disc so that the image can be processed.

DEF

A type of microfilm camera that photographs documents while they are being moved by some form of transport mechanism. The document transport mechanism is connected to a film-transport mechanism, and the film also moves during exposure so there is no difference in the rate of relative movement between the film and the image of the document.

DEF

Appareil de prise de vues qui photographie les documents alors qu'ils sont déplacés par un mécanisme quelconque. Le mécanisme de déplacement du document est rattaché au mécanisme de déplacement du film et le film bouge pendant l'exposition. Ainsi, il y a synchronisation entre la vitesse de déplacement du film et la vitesse de déplacement de l'image.

In the case of the high-speed colony picker, the machinery consists of two tables capable of computer-controlled movement positioned underneath a pair of plungers with a rotating carousel wheel in between that is fitted with 24 reusable needles. To operate the system, a Petri dish containing colonies of yeast or bacteria is placed on one table, and a 96-well microtiter plate is placed on the other. Guided by a digital image that shows the location of colonies in the dish, the first table moves a colony directly underneath a plunger which at the same time is being armed with a needle from the carousel. On a signal from a computer, the plunger dips the needle into the colony and immediately retracts it with "picked" cells. The carousel then rotates the needle over to the second plunger and the table bearing the microtiter plate moves until the correct well is directly underneath it. The computer activates the second plunger, dipping the needle into the growth medium where some of the cells will be deposited. After retraction from the growth medium, the needle is rotated by the carousel through a tank filled with sterilizing liquid and made ready for reuse.

Jason Lanier is a virtual-reality performance artist. In his piece "The Sound of One Hand", which has played to packed theatres in Chicago, Toronto and Linz(Austria), he appears on stage framed by the image of a virtual world he enters when he dons special goggles and a DataGlove. His audience sees what he sees and what he does. His movements elicit eerie, tinkling notes from the computer-generated virtual instruments he is playing : a Cybersax, a CyberXylo and a Rhythm Gimbal. He is a star of an astoundingly energized new movement of musicians and visual artists who are defining and redefining their work through the use of cybertechnology.

The exact synchronization of a visual image in a motion picture with an associative musical sound. This technique was common in the cartoon films of Walt Disney, with musical sounds accompanying every movement of the animated characters.

OBS

Hence, the technique has sometimes come to be described as "Mickey Mousing" or "Mickey Mousing the music," especially when overworked in coordinating music with image. Use of the technique, particularly in comedies and suspense stories, has proved an effective device for wedding sound to visual image.

At the same time that the patient develops movement expression [in movement or dance therapy] verbalization of feelings and group interactions are encouraged, with movement sessions taking on a decidedly social character. Dance movements as such are not taught, although the leader may express themes, suggest directions, provide music or lead discussions that help to stimulate creative expression on an individual or small-group basis. Ultimately, patients are helped to come to grips with their bodies more fully, to have a clearer image of themselves and to discover a new medium through which they can communicate their feelings and release their inner tensions.... Although primary emphasis is given [to its use] with psychiatric patients, it has also been used with the physically disabled, the elderly and even the deaf and blind as a way of helping them come to grips with their own body images and become more fully integrated emotionally and physically through nonverbal experience.

Depuis les alentours de 1950 on désigne par "expression corporelle" des techniques plus ou moins libres, induites ou dirigées, mais se présentant toutes comme différentes de la danse, du jeu théâtral ou du mime. (...) Il s'agit, dans tous les cas, d'exprimer par des mouvements ou successions de positions du corps des rythmes intérieurs et de permettre ainsi la levée de blocages et le dépassement d'interdits. (...) Si elle est, au sens large, une technique de créativité, elle peut être considérée comme une psychothérapie, utilisée seule ou comme technique complémentaire d'une psychanalyse ou d'une onirothérapie.
