Interactive multitouch table at the Hersbruck/Happburg documentation site, 2016
The second largest satellite camp of the Flossenbürg concentration camp was located in the town of Hersbruck, where 9,000 prisoners from all over Europe were held captive between July 1944 and April 1945. They were forced to dig a tunnel system in the Houbirg mountain for an armament factory in the nearby town of Happurg. Due to the extreme conditions in the camp and during the labor, around 4,000 prisoners died in Hersbruck and Happurg.
The Hersbruck/Happburg documentation site consists of two exhibition modules pointing to each other: a media installation in Hersbruck at the former location of the camp and an open air exhibition module in Happurg at the former place of forced labor: the prisoners were forced to commute 4.5 km by foot between these two locations all year round.
The Hersbruck installation features a projection of a 360° panoramic video of the surroundings of Hersbruck focussing on historically relevant places. A large multitouch table displaying the names of all the 9,000 known prisoners was designed and developed by Markus Lerner in collaboration with Bertron Schwarz Frey, who created the exhibition architecture for both locations. By touching the highlighted names, multiple visitors can simultaneously explore 90 representative biographies of prisoners from various countries featuring stories, animated quotes and images.

Multi-touchscreen installation at Grimmwelt Kassel, Germany, 2015
Words are not static. They don’t have fixed meanings. Language is constantly evolving and will continue to.
The famous German Dictionary (1838–1854/1961) by the Brothers Grimm attempts to create a “natural history of words” by focussing on associations and connections between the words rather than their abstract definitions.
Located in the newly opened Grimmwelt Kassel, Germany, “Wortarbeit” attempts to capture the visitors’ associations with words, in reference to the work of the Brothers Grimm. Within a predefined set of formulas (word connections), one word has to be explained by another word entered by the visitor. The results is a chain that grows endlessly word by word.
While one touchscreen is waiting for input, the visitors can explore the existing chain of words in various views on the other screens: chronologically, alphabetically, by popularity and through the semantic net, which reveals the complexity of the definitions entered by the visitors.
Visitors can also extend an independent chain of words in english.
The installation was designed and developed in collaboration with TheGreenEyl, Berlin.

Interactive wall projection, 2014
An interactive installation was developed for the ZEISS Museum of Optics in Oberkochen. It allows visitors to explore the known orders of magnitude in an interactive way.
A continuous zoom leads from the Planck length (1,616199 × 10−35 m) via atoms, microorganisms, everyday objects, countries, planets galaxies up to the size of the currently observable universe (2,80 × 1026 m).
The user controls the zoom via the distance from the projection surface: zoom-in by getting closer, zoom-out by stepping back. The speed of the zoom can be accelerated or reduced by using the hands additionally.
The project was realized in collaboration with TheGreenEyl (Concept, Art Direction, Production).

Interactive screen display for tade fair stand, 2008
Climate protection being the theme of the installation, each visitor is estimated to have the decision making power on over 1,540 tons of CO₂. This amount could be potentially reduced by implementing more efficient lighting. In order to emphasise the influence each individual has on the climate change, the number of trees necessary to compensate this CO2 emission is displayed.
A tracking camera records the number of visitors who enter the OSRAM stand in real time. Every new visitor triggers the growth of a new tree in the foreground of the screen. As the number of visitors increase the tree thicket gets denser as well.
The total number of viewers on one day, their CO2 saving potential and the corresponding number of trees are displayed on the top part of the LED screen.

Light installation in an urban environment, 2007
A new display for OSRAM Seven Screens in Munich was created on behalf of ART+COM, Berlin. OSRAM Seven Screens is an installation of seven double-sided vertical screens in front of the OSRAM main office in Munich, next to the highway “Mittlerer Ring”, one of the most congested roads in Munich and Germany.
For the display Reactive Sparks, the traffic on the street is tracked in real-time; each vehicle creates a spark which moves across the screens. The Waves in the lower part of the display represent the amount of traffic in the past few minutes. More traffic results in higher waves with faster movement. The installation conveys the idea of energy and movement translated it into a visual representation. The warm colours create a warm spot in the gray winter landscape. The display will run until April 2008.

Indicating mobile radiation in real space, 2004
Radiation culture is an interactive installation that visualizes the spatial distribution of mobile radiation.
Electromagnetic radiant energy feeds a synthetic bioindicator. The visual display uses the metaphor of algal growth in places of strong insolation. The absorption range in the electromagnetic spectrum, however, is shifted from visible light to long-wave radiation.
The installation refers to a space, where mobile sources of radiation like mobile phones are. This can be both a room inside a building and an area of public space, for example a place, where many people frequent. At places of concentrated radiation an alga-like shape begins to grow. It is loosely connected and can freely move in space.

Anticipation & Reality
Intermediate degree in the Digital Media Class, 2003
My intermediate diploma in thedeals with the relationship of anticipation and reality. A series of interactive screen applications explores the difference between the anticipated future and the actual reality.
Anticipation is the expectation or the mental idea of an event in the future. It originates from the ability of a subject to imagine a future. It can happen consciously or unconsciously.
The term of Reality describes the actual future reality, e.g. the consequences of an action. The mental expectations of an observer can turn out to be true or false.
