About us

Fraunhofer is Europe’s largest application-oriented research organization. Our research efforts are geared entirely to people’s needs: health, security, communication, energy and the environment.

Fraunhofer IAO helps companies and institutions introduce new technologies and processes to make their businesses more successful. With our in-depth knowledge of technologies and organizational structures, we have the skills you need to put applied research into practice.

The Visual Technologies Group at Fraunhofer IAO performs applied research in the field of display and lighting systems and technologies. This includes building novel interactive display systems as well as evaluation and measurement of display and lighting systems. Consisting of researchers from different disciplines, including electrical engineering, computer science, and psychology, CT Visual Technologies is able to cover the entire research scope from concept, systems prototyping, evaluation, to industry transfer.



Products and services

The Visual Technologies Group at Fraunhofer IAO analyzes individual requirements for intelligent workplace lighting, develops concepts based on this analysis that offer high user acceptance, and brings this new efficiency to life through pilot installations. On-site support for implementing new lighting installations is also provided.

The Visual Technologies Group conceives and develops novel interactive display environments for workplaces and meeting rooms, incorporating cutting edge display and interaction technologies, helping customers from product development and production to better cope with the challenges of digitalization and fully leverage its opportunities.

In its Lab equipped with cutting edge measuring and prototyping technology, the Visual Technologies Group validates lighting and display systems and components towards their human factors impact and technical parameters.
ProTable

ProTable

The ProTable by Fraunhofer IAO turns any conference room table into a digital working surface, transitioning the typical meeting situation of presenter/listeners to a peer-to-peer interaction. Powered by the VD1 middleware by Fraunhofer IAO, the ProTable allows to work with any application software and full integration into company IT infrastructure and processes.

Virtual Sky

Virtual Sky

Working under the open sky – it sounds enticing, but it’s seldom really a practical option. Now, a dynamic luminous ceiling brings the sky into office spaces by creating the effect of passing clouds. This kind of lighting generates a pleasant working environment. The main focus in developing the virtual sky was to simulate natural lighting conditions on a cloudy day.

Circadian Effective Display

Circadian Effective Display

Our study published at SID 2010 showed that exposure to display light in the evening affects our circadian rhythm. To reduce this effect, software as e.g. "f.lux" & "Night Shift" (iOS) shift colors in the evening to warmer colours. Our display consists of a LED-backlight with multiple, separately controllable primary colours, particularly two different types of blue. This setup allows for controlling the 480 nm level of the light emitted by the display without changing colour rendering.

News & Innovations

VR Glasses and their impact on sleep  The human circadian rythm is entrained by the sun. Using VR glasses for playing games or watching movies, the user is completely shielded from environmental lighting. There is neither an influence of natural daylight on circadian rhythm nor from artificial environmental lighting. The only light source which contributes to the circadian rhythm is the display of the VR headset. Since VR glasses are mostly used in the evening or during the night when melatonin secretion begins, phase delays of sleeping rhythms and bodily functions are expected. To quantify melanopic illuminance, the measured illuminance is weighted with the melanopic sensitivity function. The received melanopic lux correlate with the intensity of melatonin suppression. We measured and calculated values for each of the different display color and demo scenes used in VR glasses. The demo scenes are screenshots from different situations in commonly known games that can be played in virtual reality. For a white background e.g., we measured an illuminance (at eye level) of 90 lx, a melanopic action factor of 0,96 and 105,6 "melanopic lux". From this we assume that melatonin will be significantly suppressed in the evening using VR glasses. In a future study we will investigat the expected effects.
