Interactive Entertainment Displays are becoming increasingly popular across a wide-variety applications, and a large number of lighting designers, artists, and project managers are turning to lasers as the light-source of choice, to bring their creative ideas to life. 


One note-worthy Interactive Entertainment Display that has drawn a lot of media attention, is Assemblance; an immersive laser experience by artists Usman Haque and Dot Samsen who are known for their large-scale mass participatory interactive events.


This immersive experience takes over “The Pit”, a blackened room filled with three-dimensional laser-light fields inside of the Barbican Centre (London, UK). Here, visitors are able to shape, manipulate, and walk through these laser-light fields, wrapping themselves in blankets of light creating delicate 3D luminous forms in space, accompanied and encouraged by sound, which follows each gentle move.  


Like building sand castles on the beach, Assemblance explores how to structure participation in order to build trust between people, who must sometimes suspend disbelief in order to cooperate and co-exist. The space, at times magical, at times slightly sinister, creates deep emotional engagement by blurring arbitrary distinctions between physical and virtual.

“At Umbrellium we have become known for our large outdoor interactive installations which engage the public in unusual ways in urban spaces,” says Usman Haque, Umbrellium, “so it has been a fascinating and new challenge for us to design similarly engaging experiences indoors, at a finer scale. We are excited by Assemblance, our installation for the Barbican’s Digital Revolution exhibition, and look forward to witnessing how people manipulate and shape the light around them and to seeing how they collaborate with one another or otherwise in the depths of the Barbican's Pit Theatre.

What makes this art installation so incredible for those in the lighting and entertainment industry, is that it is the first time audience scanning (an effect where laser beams are intentionally projected at those in an audience area, or onto a performer themselves) has been used in a public art installation, allowing for people to actually interact with, touch, and experience the effect first hand. The technologies used to create a laser display of this caliber, and to ensure it’s safety, are also cutting-edge, and laser-entertainment industry leaders Pangolin Laser Systems, Inc. and KVANT s.r.o. were proud to have been sponsors of of the installation. 

Pangolin worked hand-in-hand with KVANT, to integrate their patented, award-winning PASS hardware (Professional Audience Safety System) into KVANT’s new ATOM “pure-diode” laser projection systems, for use at Assemblance. Pangolin’s PASS hardware is an all-encompassing laser safety system, that can ensure audience scanning effects are safe for those viewing. It’s received several international patents and awards, and is currently the standard in the United States and UK (where audience scanning is heavily regulated by government safety agencies), for those who wish to perform audience scanning laser effects. KVANT is one of the only companies in the world, certified to integrate PASS hardware into their laser projectors. For laser control, Pangolin’s LD2000/BEYOND software and QM2000.NET hardware was utilized, providing the artists with complete creative reign, in programming the desired laser effects.

William R. Benner Jr.; President and CTO of Pangolin, and developer of the PASS hardware was quoted saying “We are honored to be participating in such a ground-breaking project. This is the first laser display ever to incorporates audience scanning in an artistic premise, allowing those in attendance to interact, manipulate, and control the laser. It amazes us to see the creative and novel ways the artists at Umbrellium are utilizing Pangolin technology, to create a safe laser display of this nature”… Justin Perry, Chief Operating Officer for Pangolin, goes on to add “Interactive Entertainment Displays present great opportunities, especially for those of us in the laser and lighting industries. With lasers being such a versatile and flexible lighting medium to work with, and with new advancements being made in laser safety and control technology, we can see the segment of the market continuing to grow at a rapid pace.”

Umbrellium’s Assemblance forms part of the Barbican’s Digital Revolution, an immersive and interactive exhibition, which brings together for the first time a range of artists, filmmakers, architects, designers, musicians and game developers, all pushing the boundaries of their fields using digital media. It also looks at the dynamic developments in the areas of creative coding and DIY culture and the exciting creative possibilities offered by augmented reality, artificial intelligence, wearable technologies, laser displays, and 3-D printing.
Assemblance will sit alongside new commissions including Google's DevArt, an installation by global music artist and entrepreneur and artist Yuri Suzuki and works by Universal Everything, Seeper and Susan Kare (Mac Paint designer). Visitors will also see work by Oscar-winning VFX Supervisor Paul Franklin and his team at Double Negative for Christopher Nolan’s groundbreaking film Inception; artists and performers including Rafael Lozano-Hemmer, Chris Milk, Aaron Koblin, Fred Deakin & Company, Amon Tobin and Philip Glass and game developers such as Harmonix Music Systems (Dance Central).

LASACT – Interactive Laser Display


Over the past few years, laser entertainment technology has undergone incredible changes, with new improvements in laser technology helping to drive the industry forward. Laser projectors have become significantly more affordable to purchase and maintain, primarily due to advancements in the laser sources used. And laser control technology from companies like Pangolin has made the process of creating incredible laser displays easier than ever. As a result of these technological improvements, lasers have rapidly become an integral part of many high-profile entertainment venues and events, and we’re now seeing laser technology being used in other new and exciting applications. 


One new area we see lasers expanding into, is “Interactive Entertainment Displays”, sometimes referred to as “Crowd Art”. An Interactive Entertainment Display is essentially an installation whereby people in an audience have the opportunity to control, manipulate and in some cases touch an effect. These are becoming increasingly popular, especially in public outdoor areas where there is a desire to captivate an audience. 


A recent installation called LASACT held in Cologne, Germany for the “Platine Festival and “ArtApp Awards” is a great example of how lasers are being used for Interactive Entertainment Displays and media art.


Created by BTF Team (, including Alexander Rechberg, David Murmann, Michael König, Adrian Rennertz, and Daniel Becker… LASACT is an interactive light and sound-installation, where visitors are able to modify the visual appearance and sound patterns of a laser display, using a web application for their mobile device.

The installation uses a variety of state-of-the-art web and laser technologies to accomplish this feat, including RGB Laser Projection Systems, Pangolin’s LD2000 software, QM2000.NET hardware and software development kit, as well as “PangOSC” which is an OSC-Wrapper for the Pangolin API written by Thomas Kuleßa.

LASACT allows for fun, mesmerizing, harmonious lines to intertwine with each other, while visitors take control of the laser installation. Visitors can interact with the display on their own, but the real magic happens when they collaborate with others in the audience, to create beautifully projected effects that are the result of mutually coordinated input. All of this is possible using a wide-spread technology we commonly carry in our pockets – a smart phone. 

In an interview with the BTF Artistic Team, they noted… Nowadays brief moments of absence – induced and facilitated by the smart phone technology – are accepted even during face to face meet-ups. Despite being connected globally, members of today’s society escape the real world and dive into their own virtual bubbles. The LASACT installation conveys these aspects of communication, social relation and group dynamics. 

LASACT was awarded the “AppArtAwards" best creative development in the field of “crowd art” at the Center for Art and Media, Karlsruhe (ZKM). The sponsors for the awards ceremonies were CAS Software AG, the German Federal Ministry of Education and Research as part of the Science Year 2014 – The Digital Society, DPS Engineering and GFT Technologies AG.  

LASACT emphasizes the collaborative creation; it is an artwork in constant progression, a creation which is created just now, only during the time of performance, and in a non -repeatable matter” says Chiara Passa, Artist and Member of the voting panel. The LASACT installation serves as a great example of how laser technology is pioneering the way for Interactive Entertainment Displays, presenting new and exciting opportunities for the laser entertainment industry as a whole. 

A big thank you to Alexander Rechberg, David Murmann, Michael König, Adrian Rennertz, and Daniel Becker of BTF GmbH for their outstanding work in coordination with this installation.
