3D light walk installation immerses visitors in jena, germany

heaton huezo light walk installation overview

light walk is an interactive lighting installation designed by david heaton and sandra linton huezo for the UNESCO 2015 international year of light festival. the project is located in the german town of jena and more precisely, in the main entrance tunnel of the sonnenhof plaza- a mixed use courtyard belonging to a landmark development. also known as ‘the city of light’, jena is home to major research institutes and companies specialized in the field of optics. as a result, the town has developed remarkable expertise in lighting technologies- and the installation reflects that local capacity. 

the installation explores the relationship between light and matter 

in the project, david heaton and sandra linton huezo want to challenge the typical notions of physical space by exploring the relationship between light and matter – in different dimensions. indeed, light walk explores the two conditions of “presence” in today’s mediated world: virtual (present in a digital realm) and translocal (different locations expressed into one space). 

‘through the materialization of an ephemeral space of light, the installation engages the key concepts of translocality and augmented reality – creating an overlapping physical and digital sense of place within the square’ heaton states.

the artists translated their idea into a 3D lighting matrix that passes through three different tunnels (one main, two sideways). sensors are placed in each space to collect data from passersby’s movement once they enter. indeed, the presence of people is essential to creating the visual experience. once visitors enter a walkway, sensors detect the physical presence and translate it into a ‘data ghost’ -which appears in the form of light coming from the light walk installation.

the light tunnels are controlled by a master PC and five ‘slave’ PCs. these computers receive signals from kinetic devices in the tunnels. the position of a person in any of the walkways is relayed to the main PC, where all signals are compiled and translated into a “living drawing“ on the screen. each person is represented as a two-dimensional “blob”; they are identified by a certain color and size- based on the height of the individual. this information is then fed to a lighting program called madrix, and sent to the main controller. thus, the light walk installation introduces two different interactive dimensions. digitally, it allows the 3D light walk to respond to people’s movements. physically, it provides an intriguing social space for local and foreign visitors.

‘audiences of all ages explore various ways to interact with the installation: walking inside it, playing with it, taking selfies…these behaviors demonstrate how citizens embraced this new presence in their city center, a catalyst to support conviviality and sense of place‘ explains heaton.
