Facebook Reality Labs FRL is always exploring new optical architectures to improve form factor, comfort, and optical performance. These two methods help keep the optics as thin as possible while making the most efficient use of space. We anticipate that such lightweight and comfortable form factors may enable extended VR sessions and new use cases, including productivity. The work demonstrates the promise of better visual performance, as well: Laser illumination is used to deliver a much wider gamut of colors to VR displays, and progress is made toward scaling resolution to the limit of human vision.
This video demonstrates video game animation, as shown on our proof-of-concept research. This image shows our research device display modules mounted into a frame. This research device was used to capture the green image shown below some components are mounted externally. As the first two components can readily be formed into thin and flat modules, most of the weight and volume go into the viewing optics.
To significantly reduce the overall size and weight of VR displays, we combine two techniques: holographic optics and polarization-based optical folding. Most VR displays share a common viewing optic: a simple refractive lens composed of a thick, curved piece or glass or plastic.
We propose replacing this bulky element with holographic optics. You may be familiar with holographic images seen at a science museum or on your credit card, which appear to be three-dimensional with realistic depth in or out of the page.
Like these holographic images, our holographic optics are a recording of the interaction of laser light with objects, but in this case the object is a lens rather than a 3D scene. The result is a dramatic reduction in thickness and weight: The holographic optic bends light like a lens but looks like a thin, transparent sticker.
However, even if the lens itself is made thin, the viewing optics as a whole may still be large — a considerable amount of empty space must be placed between the display panel and the lens to properly focus the image. Ordinarily, light from the display panel propagates forward to the lens and then continues toward the eye. However, when we apply polarization-based optical folding, light can be controlled to move both forward and backward within the lens so that this empty space can be traversed multiple times, collapsing it to a fraction of the original volume.
Shown on the left, a photograph captured with the proof-of-concept research device shown above. On the right, a photograph taken through a larger full-color benchtop prototype. We are currently working on achieving full color on the smaller research prototype. When we apply holographic optics to a VR display, we must reevaluate all other optical components.
To illustrate the difference, the figure below shows the gamut of human-visible colors. A common set of colors reproducible on many displays today is the sRGB color space illustrated by the smaller triangle.Top resume writer website for mba
Note that it can capture only a small fraction of the colors that we can actually see. In contrast, the outer triangle represents the much larger set of colors that can be reproduced using the lasers on one of our research prototype displays.
This allows the reproduction of vivid and saturated colors. Think of a brightly lit neon sign or the iridescent sheen of a butterfly wing. This figure illustrates the gamut of human-visible colors. The sRGB space represents a common set of colors reproducible on many displays today. The outer triangle represents the larger set of colors reproducible on our research prototype.The next generation of transistors may pave the way for flexible, paper-thin computer screens that provide faster response times and better efficiency, scientists say.
Researchers at Japan's National Institute for Materials Science reviewed the latest developments in research on photoactive organic field-effect transistors; devices that incorporate organic semi-conductors, amplify weak electronic signals, and either emit or receive light.
The researchers reported that much progress has been made in the development of light-emitting organic field-effect transistors LE-OFETs since they first appeared in Light emission efficiency and brightness of these transistors will soon improve, researchers said. Further research may lead to production of new display technologies, they said. This may allow further development of optical communication systems and optoelectronic systems, such as those using laser technologies. These screens are purported to provide faster response times, better efficiency, and no need for backlighting.
They also have very low energy needs. Light-receiving organic field-effect transistors LR-OFETson the other hand, are much less developed than their light-emitting siblings.
Phototransistors, used in CD players, are an example of such devices that hold much promise. But their durability needs to be improved for them to be used in more flexible applications, researchers said. Flexible displays, in which all the device components - such as the light-emitting parts, the switching parts, and the substrates - consist of plastic materials have already been developed and will appear on the market in the near future, researchers said.
Paper-thin Display Market - Growth, Trends, and Forecast (2020 - 2025)
However, similar memory devices are still lacking. If "plastic memory" is developed, it will open a new frontier. Researchers estimate that it will still be another ten years before all-plastic, flexible computing devices appear on the market.
The research was published in the journal Science and Technology of Advanced Materials. Click on Deccan Chronicle Technology and Science for the latest news and reviews.
The device is about as wide as a postage stamp and can be affixed to an adhesive bandage to stay in place on someone's skin. It's made of a thin piece of rubber covered in pyramid-shaped bumps that are smaller than a human red blood cell. Those bumps shift slightly when pressure is placed on them - even pressure as subtle as the pulse of blood. Every time blood pumps through the blood vessel at the wrist, the bumps move and that movement can be used to calculate the pulse and also determine if there have been changes in the heart rate that may be problematic.
The device ultimately could be used to safely monitor heart rate information on premature babies, or to wirelessly track the heart rates and even blood pressures of patients at home. The engineers who developed it wrote up their work in the May 12 issue of Nature Communications.
San Francisco's Twitter is a popular, and for the most part, an educated and reliable source of medical information for health care consumers, according to research out of Texas. The researchers focused on the spread of information related to vaccinations over a one-week period in January Looking at a sample of 2, messages that had been re-posted and shared between users, the researchers studied the tone of the messages, the sources and whether the information was backed up by science.
About a third of the messages were positive toward vaccines, 54 percent were neutral and 13 percent were negative.
Paper-thin Displays: Technologies and Global Markets
Fourteen percent of messages contained medical information, and two-thirds of those messages were substantiated by research. The most popular messages were about a potential malaria vaccine for children, a vaccine for breast cancer, a vaccine for lung cancer, effectiveness of the herpes vaccine in women, recommendations for the human papilloma virus vaccine for boys, and a single blog post discrediting connections between autism and vaccines.
The researchers said they found that Twitter was a potentially useful tool to disseminate positive, reliable health care information, and they noted that users tend to share information that comes from well established sources. California children are drinking less soda, but among minority kids, consumption of fruit juice - which often has just as much sugar as a sweetened soft drink - has increased, according to researchers at UCSF and San Francisco General Hospital.Article europe vote vs trump
The results were based on the California Health Interview Survey, which is conducted every two years by telephone. Parents were asked whether their children had consumed a soda or fruit juice the previous day, and how many servings of soda or fruit juice their kids drank each day. The percentage of kids ages 2 to 5 who drank soda dropped from 40 percent in to 16 percent in ; among kids ages 6 to 11, soda consumption fell from 54 percent to 33 percent over the same time period.
Soda consumption fell across all ethnic groups, although rates were higher among Latino and black children than white children. Among white children in both age groups, fruit juice consumption fell or was stable from to But consumption of juice increased for both black and Latino children ages 6 to 11; it also increased among Latino children ages 2 to 5. Authors of the study said more work needs to be done to inform parents that fruit juice is not an acceptable alternative to soda, and that children are better off with water or milk.
The American Academy of Pediatrics recommends that children age 6 and under drink no more than 6 ounces of fruit juice a day; a serving is 8 ounces. A protein that is secreted only by specific cells deep within the brain acts like Valium and may help the body naturally control certain types of epileptic seizures, according to Stanford researchers.
The protein, known as a diazepam binding inhibitor DBIcalms the rhythmic waves of brain circuits that can cause seizures when they're overstimulated. Discovery of the protein could help scientists develop better, safer drugs to treat epilepsy by targeting specific molecular pathways in the brain. Valium was one of the first effective treatments for epilepsy. The drug, like the DBI protein, has a calming effect on the brain circuits that can go haywire in a seizure.
But it is highly addictive, easily abused and can be dangerous at high doses, and it is rarely used to treat epilepsy now that better drugs have replaced it. If scientists tracking DBI can identify how the naturally occurring protein acts - or misfires, in the case of epileptic patients - they could find specific avenues for new treatments. DBI might also help scientists discover treatments for anxiety and sleep disorders. Discovery of the protein and some of its activities in the brain were written in a paper published Thursday in the journal Neuron.
Stanford researchers have made progress in the effort to train the immune system to go after cancer cells without triggering the body's defense system to call off the attack. Harnessing the immune system to kill cancer cells has long been challenged because of the body's ability to eventually recognize the cancer cells as "self," and thus stop the body from attacking itself.
Immune cells called T regulatory cells, or Tregs, play a key role in that process. The researchers discovered a way to block the activity of Tregs in laboratory mice by injecting specific antibodies directly into the tumor.
These antibodies get rid of the Tregs that are mixed with the tumor cells, allowing the body's killer immune cells to go after the cancer unabated.
Holographic optics for thin and lightweight virtual reality
While some anti-Treg antibodies have already been approved and used in humans, these treatments are known to expose normal cells to the wrath of the immune system.This market is forecast to grow at a compound annual growth rate CAGR of Have a Question?

With this, a daily newspaper could be uploaded onto a flexible paperlike display that could be updated as fast as the news cycles. The team focused on two key innovations for achieving highly flexible designs. The first is the recent development of optically rewritable LCDs.
Like conventional LCD displays, the display is structured like a sandwich, with a liquid crystal filling between two plates. Unlike conventional liquid crystals where electrical connections on the plates create the fields required to switch individual pixels from light to dark, optically rewritable LCDs coat the plates with special molecules that realign in the presence of polarized light and switch the pixels.
This removes the need for traditional electrodes, reduces the structure's bulk and allows more choices in the type and thickness of plates. Consequently, optically rewritable LCDs are thinner than traditional LCDs, at less than half a millimeter thick, can be made from flexible plastic, and weigh only a few grams.
Optically rewritable LCDs are durable and cheap to manufacture because of their simple structure. Moreover, like an electronic paper screen in an e-book, energy is only required to switch display images or text.
Therefore, running costs are low because these new LCDs don't need power to sustain an image once it is written on the screen. The second innovation involves the spacers that create the separation of the plastic or glass plates.Spine title thesis
Spacers are used in all LCDs to determine the thickness of the liquid crystal. A constant thickness is necessary for good contrast ratio, response time and viewing angle. However, when plates bend, it forces the liquid crystal away from the impact site and leaves sections of the screen blank and so alterations in spacer design are critical to prevent liquid crystal in flexible LCDs from moving excessively.
Developing a flexible design that overcomes this barrier has proven challenging. The researchers tried three different spacer designs and found that a meshlike spacer prevented liquid crystal from flowing when their LCD was bent or hit.Cool functions for math students
This innovation enabled them to create the first flexible optically rewritable LCD. An additional innovation involved improved color rendering.
The scientists report that until this study, optically rewritable LCDs had only been able to display two colors at a time. Now, their optically rewritable LCD simultaneously displays the three primary colors.
They achieved this by placing a special type of liquid crystal behind the LCD, which reflected red, blue and green. To make this into a commercial product, Sun wants to improve the resolution of the flexible optically rewritable LCD.
