OLED microdisplays in data glasses for improved human-machine interaction

22.09.2016

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.

“Augmented-reality” and “wearables” have become terms we encounter almost daily. Both can make daily life a little simpler and provide valuable assistance for patients, athletes, and in manufacturing. With the help of the so-called bi-directional OLED microdisplays, which are developed by Fraunhofer FEP, the function of “wearable displays” and hands-free eye controlled systems are joined together in a unique way.

“Eye-controlled augmented-reality smart glasses using our OLED microdisplays can be designed to be relatively small and light-weight since the display and image sensor are integrated on a single chip. A new and improved development platform is now available to our clients for creating proprietary products”, explains Judith Baumgarten, Project Manager at Fraunhofer FEP.

The current generation of color bi-directional microdisplays offers SVGA resolution (800 × 600 × RGBW) and for the first time sufficient image quality to become established in this market segment. The updated hardware design with standard HDMI and USB interfaces likewise contribute to getting established.

The eyeglasses exhibited at AWE Europe 2016 originated within the FAIR Project completed this year, was funded by the German Federal Ministry of Education and Research (BMBF). The project objective was to develop smart glasses for human-machine interaction, with control based on visual information captured and derived from eye movements.

The bi-directional full color OLED microdisplays integrated into see-trough data eye-glasses under this joint project were designed by project partner Trivisio, who developed a specialized mechanical design to fit the head in order to achieve good comfort and wearability. The electronics were integrated completely into the glasses so that they can be connected to a PC without an intermediate controller.

Where can these types of smart glasses become beneficially employed?

Various use-cases were examined and suitable application software for guide-by-eye control were developed by project partners Interactive Minds and Mecotec. One application developed is a communications and entertainment platform for ALS patients. It converts pre-composed text segments as well as those created by the patients themselves into audible speech signals, as well as enabling photographs to be selected and displayed, and videos and music to be watched and listened to.

Another application was developed for industry. In this case the glasses were used for calibration of pressure regulators in production facilities. Technical University Dresden monitored the project both with respect to the ALS patients (through the university’s Klinik und Poliklinik für Neurologie (hospital and ambulatory neurology)), as well as carrying out studies on ergonometry and user-friendly design (via the Chair for Industrial Psychology and Applied Cognition Research).

Besides these application examples, the advanced bi-directional OLED microdisplays of Fraunhofer FEP open up a whole world of possibilities and opportunities. The displays can be acquired in various evaluation kits for industry partners to test out their own ideas. This facilitates the integration of the displays in client-specific applications, and our scientists look forward to new research and development projects.
The SID-ME 2017 conference in Dresden next year (March 13th – 14th) is dedicated to the world of “wearable displays” and everything that goes with them. Experts will meet here to discuss technologies and applications.

The project partners would like to thank the German Federal Ministry of Education and Research (BMBF) for funding the FAIR research project (funding reference 16SV5842).

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
