Google's Heads Up Display (HUD) Glasses

Google's HUD glasses have been sighted | Digital Media - CNET News

In December, rumors spread that Google was finishing up a prototype on high-tech glasses known as wearable head-up displays (HUD) that could tap into Google's cloud-based location services and detail users' surroundings. The information would then appear as an augmented reality computer display.

Over the last year, Apple and Google have secretly begun working on projects that will become wearable computers. Their main goal: to sell more smartphones. (In Google’s case, more smartphones sold means more advertising viewed.)

In Google’s secret Google X labs, researchers are working on peripherals that — when attached to your clothing or body — would communicate information back to an Android smartphone.

People familiar with the work in the lab say Google has hired electronic engineers from Nokia Labs, Apple and engineering universities who specialize in tiny wearable computers.

They are in late prototype stages of wearable glasses that look similar to thick-rimmed glasses that “normal people” wear.  However, these provide a display with a heads up computer interface.  There are a few buttons on the arms of the glasses, but otherwise, they could be mistaken for normal glasses.  Additionally, we are not sure of the technology being employed here, but it is likely a transparent LCD or AMOLED display such as the one demonstrated below:

In addition, we have heard that this device is not an “Android peripheral” as the NYT stated.  According to our source, it communicates directly with the Cloud over IP. Although, the “Google Goggles”  could use a phone’s Internet connection, through Wi-Fi or a low power Bluetooth 4.0.
The use-case is augmented reality that would tie into Google’s location services.  A user can walk around with information popping up and into display -Terminator-style- based on preferences, location and Google’s information.

HUD Google Glasses are real and they are coming soon | 9to5Google | Beyond Good and Evil

Our tipster has now seen a prototype and said it looks something like Oakley Thumps (below). These glasses, we heard, have a front-facing camera used to gather information and could aid in augmented reality apps. It will also take pictures. The spied prototype has a flash —perhaps for help at night, or maybe it is just a way to take better photos. The camera is extremely small and likely only a few megapixels.

I/O on the glasses will also include voice input and output, and we are told the CPU/RAM/storage hardware is near the equivalent of a generation-old Android smartphone. As a guess, we would speculate something like 1GHz ARM A8, 256MB RAM and 8GB of storage?  In any case, it will also function as a smartphone.

Lumus Wearable Display

Walk And Watch HD Movies With Lumus’ See-Through Video Glasses


Video eyewear hasn’t been the most practical — or even quality — technology to emerge over the past 10 years, but it still carries an essence of the future with it. And while they’re not any more practical, Lumus Technologies’ 720p DK-32 see-through video eyewear struck enough of a balance between picture quality, wearability and that future factor for my enjoyment.

Lumus see-through wearable display hands-on at CES 2012 - YouTube


Lumus was showing off two different types of wearable displays, the development kit -- or DK-32 shown above -- and the PD-18-4 a monocular version using the same technology. Driven by Lumus' patented Light-guide Optical Element, a micro-display pod, and the Optical Engine which projects light into the lens -- where it is reflected back to the user's eye via reflectors embedded in the lens -- the Lumus' DK-32 delivers a bright 720p 3D-capable display that only weighs 27 grams.

Lumus - The Lumus Solution




See-through and large screen effect
Unlimited screen size is one of the most innovate and coolest features of Lumus' see-through capability, enabling users to literally experience the world's largest screen. While display brightness and contrast are optimized to block out ambient background when watching video content, the Field of View surrounding the active image remains clear, with the image appearing as though it is being projected onto whatever background is visible. For example, when viewing an image with a wall in front of the wearer, the image appears as if it is a large screen projected on that wall. When outside and looking at the view several blocks away, the image appears as if it is hundreds of feet wide. This phenomenon is explained by the unlimited distance perception enabled by the see-through capability - the farther the distance observed around the active image, the larger the image appears.

Lumus - Advantages

  • Unobtrusive, natural look and feel of regular eyeglasses, which can be worn all day, even when screen is off
  • Huge expandable screen with image appearing even larger over distance
  • Situational awareness enabling watching on the go while seeing what's going on around you
  • Hands-free flow of critical data, keeping you constantly connected no matter what you are doing
  • Personal and private screen allowing discreet viewing of video and data anywhere
  • Augmented reality content overlaid on what you see, enabling revolutionary applications
  • Stereoscopic image enabling mind-blowing 3D video and gaming
  • No fatigue or dizziness because of open peripheral vision and proprietary alignment methods and procedures

Bionic Contact Lens Prototype

Bionic contact lens - Wikipedia, the free encyclopedia



Bionic contact lenses are being developed to provide a virtual display that could have a variety of uses from assisting the visually impaired to the video game industry.[1] The device will have the form of a conventional contact lens with added bionics technology.[2] The lens will eventually have functional electronic circuits and infrared lights to create a virtual display.[citation needed]
Babak Parviz, a University of Washington assistant professor of electrical engineering is quoted as saying "Looking through a completed lens, you would see what the display is generating superimposed on the world outside.”[3]

Successful test for electronic contact lens | ZDNet

Researchers at the University of Washington and Aalto University, Finland, have built a prototype electronic contact lens and demonstrated its safety by testing it on live rabbit eyes.

The researchers report no signs of adverse side effects in a study published today in IOP Publishing’s Journal of Micromechanics and Microengineering,

“We have demonstrated the operation of a contact lens display powered by a remote radiofrequency transmitter in free space and on a live rabbit,” said lead researcher, Babak Parviz.



One Per Cent: Electronic contact lens displays pixels on the eyes

The test lens was powered remotely using a 5-millimetre-long antenna printed on the lens to receive gigahertz-range radio-frequency energy from a transmitter placed ten centimetres from the rabbit's eye. To focus the light on the rabbit's retina, the contact lens itself was fabricated as a Fresnel lens - in which a series of concentric annular sections is used to generate the ultrashort focal length needed.

They found their lens LED glowed brightly up to a metre away from the radio source in free space, but needed to be 2 centimetres away when the lens was placed in a rabbit's eye and the wireless reception was affected by body fluids. All the 40-minute-long tests on live rabbits were performed under general anaesthetic and showed that the display worked well - and fluroescence tests showed no damage or abrasions to the rabbit's eyes after the lenses were removed.

3D TV Without Glasses

3D TV Without Glasses - Revealing How No Glasses 3D TV Works.....

Everyone recognises that the need to wear 3D glasses is one of the major barriers to the mass acceptance of 3D TV as an entertainment medium. 3D glasses are expensive, uncomfortable for some, and the need to wear them means you'll need multiple pairs if watching with friends or family. In this article we'll look at developments in technology that will allow you to experience 3D TV without glasses.

The breakthrough technologies that solve this problem of no glasses 3D TV are known as parallax barrier or lenticular lens technology. These methods of delivering 3D TV without glasses are also known as autostereoscopy, and the 3D TVs that deliver them are built using what's termed as 'autostereoscopic screens'. LG's blog post 'A 3D Future Without Glasses' explores the two technologies in more detail.


Autostereoscopy - Wikipedia, the free encyclopedia

Autostereoscopy is any method of displaying stereoscopic images (adding perception of 3D depth) without the use of special headgear or glasses on the part of the viewer. Because headgear is not required, it is also called "glasses-free 3D" or "glasses-less 3D". The technology also includes two broad approaches used in some of them to accommodate motion parallax and wider viewing angles: those that use eye-tracking, and those that display multiple views so that the display does not need to sense where the viewers' eyes are located.[1] Examples of autostereoscopic displays include parallax barrier, lenticular, volumetric, electro-holographic, and light field displays.


Comparison of parallax-barrier and lenticular autostereoscopic displays. Note: The figure is not to scale.


A disadvantage of the parallax barrier is that because each eye is allowed to see only half the pixels, light travelling in the “wrong” direction – i.e. from an L stripe to the right eye or from the R stripe to the left eye – is absorbed by the barrier. This cuts the intensity from the display by about half and reduces the resolution. In practical terms, this means that when the display is being used in conventional 2D mode, the parallax barrier should be removed. In most 3D displays, such as Sharp’s 3D mobile phone, this is achieved by making the barrier from a liquid-crystal layer that can be turned on or off electrically.






Glasses-Free 3D: Sooner Than You Think? | PCWorld


In addition to the limited viewing range and angle problems mentioned above, the unfortunate fact is that the actual depth of the 3D effect in these autostereoscopic TVs is, frankly, disappointing. It's far too subtle to be exciting, and I often found myself looking for the 3D effect in an image or a clip when I should have been blown away.

A Complete Review To 3D TV Without Glasses

Conclusion

At the moment, it is fair to say that 3D TV without glasses is very much at a developmental stage, and the small sets on offer are not going to be threatening the domination of 3D glasses in the very near future.
The speculation actually coming from within the technology players that produce TVs hasn’t been entirely positive either, with Samsung suggesting it may be as much as 10 years until they can release TV sets with the ability to provide 3D images without having to use 3D glasses, and Sony has also confirmed that the release of sets with this capability is years rather than months away.
Whilst the Toshiba Regza TVs that have been released in Japan are aimed at ‘early-adopters’, and are fairly successful in producing the results required, they aren’t going to be realistic commercial options for some time to come.

3D Imaging by Surface-Plasmon Holography

Holograms Powered By Quantum Effects Can Show True Color From Any Angle | Popular Science

A new type of hologram harnesses a quantum effect and uses ordinary light to make 3-D still images. Future 3-D displays based on this technology would have no need for 3-D glasses or special screens.

The technique is based on the behavior of free electrons on a metal surface, according to researchers at the RIKEN Institute in Japan.

Holography sharpens up - physicsworld.com


This tasty looking apple is an image of a new type of hologram developed in Japan that exploits tiny vibrations in metallic surface known as "surface plasmons". The image holds its rich natural colours even as the viewer changes their position, unlike many existing holograms on the market. For this reason, the researchers believe that their innovation could lead to new display technologies such as smart-phone screens that can project lifelike 3D images.
[...]
To see the hologram, the researchers needed to illuminate the structure with white light to generate surface plasmons in the silver film. Plasmons are coherent electron oscillations that can be thought of as a quasiparticle that couples photons and electrons. By illuminating the hologram in three distinct directions, the researchers were able to generate plasmons corresponding to the red, green and blue features of the hologram.



Plasmon - Wikipedia, the free encyclopedia

In physics, a plasmon is a quantum of plasma oscillation. The plasmon is a quasiparticlequantization of plasma oscillations just as photons and phonons are quantizations of light and mechanical vibrations, respectively. 

Surface plasmon - Wikipedia, the free encyclopedia

Surface plasmons (SPs), are coherent electron oscillations that exist at the interface betwterface (e.g. a metal-dielectric interface, such as a metal sheet in air).

Schematic representation of an electron density wave propagating along a metal - dielectric interface. The charge density oscillations and associated electromagnetic fields are called surface plasmon-polariton waves. The exponential dependence of the electromagnetic field intensity on the distance away from the interface is shown on the right. These waves can be excited very efficiently with light in the visible range of the electromagnetic spectrum.

Surface plasmon hologram and its color reconstruction with white-light illumination. (A) The SPP hologram is illuminated by white light at a given angle ? in high-index medium. Surface plasmons of a selected color are excited and diffracted by the SPP hologram to reconstruct the wavefront of the object. (B) Dispersion curve of the SPP hologram in reconstruction as a function of the incident angle of white light. The 3D images of red, green, and blue cranes made of paper are obtained at different angles with white-light illumination. This curve was obtained through calculations based on Fresnel’s equations. (C) Reconstruction of a color object through SPP hologram. The hologram is illuminated simultaneously with a white light in three directions at different angles  for each.

One Per Cent: Quantum effect fuels colour-fast holograms



"Currently 3D TV receivers, 3D games machines and 3D movie theatre screens create an illusion using left and right eye images reconstructed by the brain," says Kawata. "We are creating an optical field in 3D from the actual object in natural colour - there is no illusion."

He hopes their technique will feed into research on new ways to make glasses-free 3D moving picture screens, as well as making holograms look more realistic.

Samsung's Full-Color Display with Quantum Dots

Connect the quantum dots for a full-colour image : Nature News




low-energy televisions.

Ink stamps have been used to print text and pictures for centuries. Now, engineers have adapted the technique to build pixels into the first full-colour 'quantum dot' display — a feat that could eventually lead to televisions that are more energy-efficient and have sharper screen images than anything available today.

Engineers have been hoping to make improved television displays with the help of quantum dots — semiconducting crystals billionths of a metre across — for more than a decade. The dots could produce much crisper images than those in liquid-crystal displays, because quantum dots emit light at an extremely narrow, and finely tunable, range of wavelengths.

Dots deliver full-colour display - physicsworld.com



Researchers in South Korea and the UK say that they have produced the first large-area, full-colour display based on red, green and blue quantum dots. The technology could spur the launch of colour TV screens combining a vast colour range with an incredibly small pixel size.

Both attributes stem from the intrinsic properties of the quantum dots, which despite being just a few nanometres in diameter comprise several thousand atoms that form tiny compound-semiconductor crystals. [...]

The First Full-Color Display with Quantum Dots - Technology Review



Samsung's four-inch diagonal display is controlled using an active matrix, which means each of its color quantum-dot pixels is turned on and off with a thin-film transistor. The researchers have made the prototype on glass as well as on flexible plastic, as reported in Nature Photonics this week. "We have converted a scientific challenge into a real technological achievement," says Jong Min Kim, a fellow at the Samsung Advanced Institute of Technology.
[...]
Quantum-dot displays would consume less than a fifth of the power of LCDs, says Samsung researcher Tae-Ho Kim. They promise to be brighter and longer-lasting than OLEDs. What's more, they could be manufactured for less than half of what it costs to make LCD or OLED screens.

This potential has caught the attention of big display manufacturers other than Samsung. LG Display is partnering with MIT spinoff QD Vision to develop quantum-dot displays.
