Lounging on a sofa while watching a 3D movie is an exquisite pleasure for many film fans. Be that as it may, those nettlesome 3D glasses might diminish the fun somewhat. That’s why television manufacturers are working on displays that can recreate the spellbinding magic of three-dimensional television images – without the glasses.
Though prototypes of these TV screens already exist, consumers will not have to wait much longer for the market introduction of these autostereoscopic displays. Neverthe-less, the content might be a bit problematic: The 3D movies currently available on Blu-ray are based on two different perspectives, i.e., two images, one for each eye. However, autostereoscopic displays need five to ten views of the same scene (depending on the type).
In the future, the number will probably be even more. This is because these displays have to present a three-dimensional image in such a manner that it can be seen from different angles – indeed, there is more than one place to sit on a sofa, and you should be able to get the same three dimensional impressions from any position.
Researchers at Fraunhofer Institute for Telecommunications, Heinrich-Hertz Institute, HHI in Berlin recently developed a technology that converts a Blu-ray’s existing 3D content in a manner that enables them to be shown on autostereoscopic displays. “We take the existing two images and generate a depth map – that is to say, a map that assigns a specific distance from the camera to each object,” says Christian Riechert, research fellow at HHI. “From there we compute any of several intermediate views by applying depth image-based rendering techniques. And here’s the really neat thing:
The process operates on a fully automated basis, and in real time.” Previous systems were only capable of generating such depth maps at a dramatically slower pace; sometimes they even required manual adaption. Real-time conversion, by contrast, is like simultaneous interpretation: The viewer inserts a 3D Blu-ray disc, gets comfortable in front of the TV screen and enjoys the movie – without the glasses. Meanwhile, a hardware component estimates the depth map in the background and generates the requisite views. The viewer is aware of nothing: He or she can fast forward or rewind the movie, start it, stop it – and all with the same outstanding quality. The flickering that could appear on the edges of objects – something that happens due to imprecise estimations – is imperceptible here.
The researchers have already finished the software that converts these data. In the next step, the scientists, working in collaboration with industry partners, intend to port it onto a hardware product so that it can be integrated into televisions. Nevertheless, it will still take at least another calendar year before the technology hits department store shelves. At the IFA trade show in Berlin from August 31 to September 5 the technology can be tested: An autostereoscopic 3D screen will be set up right in front of a sofa corner at Booth 10 in Hall 11.1. Visitors can select from the various 3D Blu-ray discs, and as the disc is played, the system will convert it live: the visitors just relax and enjoy the movie – without the glasses.

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.
In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
Every three years, the plastics industry gathers at K, the international trade fair for plastics and rubber in Düsseldorf. The Fraunhofer Institute for Laser Technology ILT will also be attending again and presenting many innovative technologies, such as for joining plastics and metals using ultrashort pulse lasers. From October 19 to 26, you can find the Fraunhofer ILT at the joint Fraunhofer booth SC01 in Hall 7.
K is the world’s largest trade fair for the plastics and rubber industry. As in previous years, the organizers are expecting 3,000 exhibitors and more than...
