• The Emirati National House

    Interactive map of the United Arab Emirates, 2016

    A high-resolution interactive multitouch map was developed for the National Pavilion of the United Arab Emirates at the 15th international architecture exhibition – la Biennale di Venezia.

    It provides insights into the geography and landscape of the UAE, as well as the diversity in typology of the Emirati National House, also know as the Sha’abi (folk) housing model, applied across the Emirates.

    Multiple visitors simultaneously are able to zoom in to neighborhoods to examine their qualities and view photographs documenting the unique features of the Sha’abi houses. An overview map, where the currently selected map areas are indicated, provides general orientation within the country.

    The Emirate National house was introduced in the 1970s to settle transient population and provide modern amenities. Architecturally it was based on a courtyard housing typology derived from traditional precedents. As the resident’s needs evolved, a series of changes took place: functional ones likes the addition of rooms, enlargement of living spaces and the raising of enclosure walls to ensure privacy as well as aesthetic or symbolic ones: replacing entrance doorways and repainting outer walls. These modifications resulted in visual diversity, moving away from a monotonous appearance.

    The exhibition curated by Prof. Yasser Elsheshtawy, intents to move the urban housing discourse in the UAE to one that is grounded in the every day life of its citizens.

    The exhibition is open to the public from May 28 until November 27, 2016.

    Update: The interactive map is on display again as part of the exhibition ›Untold Stories Retold‹ at Warehouse421, Abu Dhabi, from 07 March until 24 June 2018.

  • Hersbruck/Happurg

    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.

  • Wortarbeit

    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, media planning by Stefan Helling.

  • Micro – Macro

    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).

  • Mendelssohn-Effektorium

    Virtual orchestra for the Mendelssohn-Haus Leipzig, 2014

    The Mendelssohn-Effektorium is a virtual orchestra at the Mendelssohn-Haus in Leipzig. It was developed and produced by WHITEvoid. Markus Lerner was commissioned for the Screen Design and OpenGL software development.

    13 speakers with vertical displays are arranged behind a conductor’s stand, each one representing a different group of instruments or choir voices. Visitors can select one of the works of Felix Mendelssohn-Bartholdy at the stand and conduct the virtual orchestra or choir by moving the coductor’s baton. The speed of the recordings is then adjusted in real-time. Voice groups can be controlled individually and different room situations can be set. The installation also allows one to compare modern and historical instruments.

    The vertical screens can display the names of the voices, the sound level or an artistic interpretation of the voice groups influenced by the volume and character of each instrument/voice.

    The idea for the Effektorium originated in the cooperation between Studio Bertron Schwarz Frey and WHITEvoid. Sound production and programming by Aconica.

  • Interactive journey in time

    Interactive table at the Museum of Hamburg History, 2012

    A part of the new exhbition »The harbour – a key stimulus«, the interactive table leads through 1300 years of Hamburg history. The square table with 3.5 sqm surface area enables visitors to explore the development of the city from the Middle Ages until today.

    A mechanical time wheel is used to navigate through the 11 periods. In each era, the most important changes in urban development as well as significant historical events are geographically displayed on the map, for example the North Sea flood of 1962 or the construction of the Speicherstadt. The bilingual content windows appear on different sides of the table, which enables several visitors to explore information independently. The programming was done on behalf of ART+COM (Concept, design and production).

  • Solar Module Designer

    Interactive web, touch screen and iPad application, 2011

    The Solar Module Designer is as an interactive application, which allows one to design and configure the most diverse forms of solar modules with ease. This tool is available as an online application, a touch screen installation for trade shows and an iPad App.

    It was developed in collaboration with Plural Kilian Krug.

    Due to the need for a tool that helps architects visualise the various configurations that Odersun offers, we developed this communication tool that also helps the architects integrate unusual module shapes into their design/production drafts.

    The custom designed solar modules can be exported as PDF/CAD-files, which can be directly integrated in construction plans or used as a reference in module manufacturing.

  • Interactive city map

    Multitouch table in the Red Town Hall, Berlin, 2009

    A part of the “Be Berlin” campaign, the interactive table in the shape of the city of Berlin, located in the foyer of the main municipal building (Rote Rathaus) Berlin, which is visited by a large number of tourists daily, shows bilingual descriptions of sights and stories from berliners on a satellite map.

    The table allows visitors to get an insight into the many attractions berlin offers with historical pictures, descriptions in german/english and trivia. The multitouch surface enables several users to explore the content at the same time. This project was done in collaboration with Felix Hardmood Beck (exhibition design, draft, consulting) and Hermann Klöckner (consulting) of ART+COM.

    One can view the Be Berlin Table at the Red Town hall during working hours Monday–Friday, unless there is a private gathering.

  • Polygon Playground

    Dynamic Lounge Object, 2008

    The Polygon Playground is a large scale interactive lounge object developed and produced by WHITEvoid. Markus Lerner was commissioned for the Tracking/OpenGL software development.

    The object offers room for up to 40 persons at a time to walk, sit and explore its multifaceted surfaces. Gradient ramps guide to the top plateau or offer space to sit and rest. The installation features a software aided 3D surface projection system to cover the object with a seamless 360 degree projection. An additional sensory system detects peoples positions and proximity.

    The visual appearance of the Polygon Playground changes continuously with the presence, movement and physical touch of its visitors. The object detects the positions and directions of people and reacts with evolving visual moods and graphic styles.

    The hardware and software system of the Polygon Playground can be applied to virtually any 3D body to turn it into an interactive object.

  • Reactive Growth

    Interactive screen display for tade fair stand, 2008

    An interactive screen display was developed for the OSRAM stand at the light+building trade fair in Frankfurt in collaboration with ART+COM.

    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.
