arc/sec Lab

online online

The virtual exhibition by the arc/sec Lab presents installations in 1:1 scale and video documentations of the four projects: LightWing II, LightTank, LightScale II and Singularity.

Immersive installations are part of the research conducted at the arc/sec Lab for Cyber-Physical Architecture and Interactive Systems at the University of Auckland in New Zealand by Uwe Rieger and Yinan Liu.

arc/sec Lab hub can be viewed on a computer screen using the latest version of Firefox or Chrome browser or using a VR headset.


LightWing introduces 3D projection mapping on a kinetic object. It creates a mysterious sensation of a tactile data and follows arc/sec`s mission to explore digital augmentation of structure and material. The project applies cross-reality design principles by using anaglyph projection technique on a transparent surface. Upon the touch of the visitor, the structure oscillates through space and generates responsive holographic constructions of light.

LightTank is a mixed reality installation that augments a space frame structure with holographic line drawings. Using the anaglyph (red/cyan) stereo projection technique on transparent screens the haptic-digital construction merges with its surrounding and blurs the boundaries between tactile and virtual. LightTank creates a communal immersive experience with an intimate responsiveness to its audience.

The project was conceived by the arc/sec Lab for Digital Spatial Operations at the School of Architecture and Planning at the University of Auckland. LightTank`s interface was developed in collaboration with the Augmented Human Lab at the Bio Engineering Institute. Under the lead of Assoc. Prof. Suranga Nanayakkara, the AHLab focuses on creating enabling human-computer interfaces as natural extensions of our body, mind and behaviour.

Singularity is a unique interdisciplinary architecture-dance-music experience that shifts our perception of architecture as a static construction towards an intelligently reacting behaviour.

The project creates a Cross Reality world. Large 3D holographic constructions appear interactively in space, visible without the need of any additional devices (goggles, screens, helmets etc). The installation combines a live render programme with a motion tracking system and a triangular setup of projectors illuminating a volume of haze particles. The outcome is 360 degrees haptic–digital space, accurately defined in all dimensions, interactive and inhabitable.

Marked with tracking devices three dancers interact with the holographic volumes. Audience and performer experience an intermixing of physical movement and data through transforming arcs of light. Clouds of data become wormholes, kites, watery walls and particle streams in response to live dance and techno sound.
SINGULARITY was first presented at Q Theatre in Auckland on 2.11.2016. The project was newly developed as a two part performance for Ars Electronica Festival in Linz Austria. 10 shows were presented under the title `Drawing Spaces` and `Breathing Spaces` from 7.-11.9.2017.

LightScale II

LightScale II floats through a virtual ocean like a giant whale, materialising environments, events and user interactions on its path. The installation generates a tactile data experience through 3D projections onto multi-layered gauze surfaces. The kinetic structure consists of a 20-metre long carbon construction, mounted asymmetrically on a single point support.

On a touch of the visitor the construction oscillates freely through space. A motion tracking system combined with ultra sound sensors recognises touch, position and movement of the LightScale. A live-render program overlays the physical construction with projected place bound and interactive digital information. The project has its roots in a design by kunst und techink (R. Hartl, M. Janekovic, U. Rieger, H. Schroeder) in Berlin in end 90’s. Equipped with latest digital spatial technologies LightScale II now advances towards an responsive navigation tool that creates haptic-digital constructions and materializes spatial narratives.
