BrightSign and Dubai-based system integrator DigiComm have completed a new digital attraction on the 125th floor of Dubai’s iconic Burj Khalifa. At 160 stories and over 2,717 feet tall, the skyscraper has been wowing visitors for almost 10 years.

A trip to the top is not for the faint-hearted. As well as breathtaking views from the world's highest outdoor observation deck, thrill seekers can experience scaling the outside of the structure and parachuting off the top thanks to an immersive virtual reality simulation.

It was in this context that the tower's owners Emaar Properties looked to create a sensational new attraction on the 125th floor of the building known as "At the Top," which receives around 10,000 visitors per day. Together with digital media partner LG, they developed the concept of an interactive, realistic simulation of a glass floor above the city that appears to crack when stepped on.

"They wanted something really spectacular and very entertaining," said Abdul Bakhrani, CEO of Dubai-based digital media studio and systems integrator DigiComm, which created the content, media, and special effects for the attraction, as well as for other installations within the building including the VR experience. With seven world records to its name, including its status as the world's tallest building, Burj Khalifa is all about superlatives.

Eighteen 55-inch LG OLED 8K-resolution screens made of extremely durable toughened glass make up the floor, powered by two BrightSign XT1144 expanded I/O players. The screens display a highly realistic visual animation of the city 1,496 feet below, which changes according to the time of day and season, scheduled and controlled by the BrightSign players.

Fifteen Nexmosphere XDW-M44 sensors are used in the installation. On one side there are seven Nexmosphere sensors connected to the RS232 XM-350 Xperience Controller, and on the other there are eight sensors connected. These Xperience Controllers then link up to the BrightSign XT1144 media players.

When a visitor trips a sensor, a virtual crack starts forming on the skywalk floor and escalates; as they keep walking, the glass is cracking beneath them. The high-resolution CGI graphics combined with synchronized audio results in a thrilling sensation of glass cracking beneath the visitor’s feet, 125 floors above ground.

According to Bakhrani, using OLED screens in this way was something new, and deploying motion sensors with so many thousands of people was also a challenge. "It took quite a bit of trial and error to get the configuration just right. We ourselves didn't know how it would work with such large visitor numbers. We were testing the waters, gathering feedback and constantly improving. It took about two weeks of fine-tuning once it was live to perfect it."

BrightSign players were selected because they are highly robust, technically viable, and cost-effective. "The requirement was for players that could be deployed and then left to run 24 hours a day with minimal management," said Bakhrani. It is not anticipated that the media content will change for some time as the exhibit is highly popular and effective, and most visitors are tourists who come only once to Burj Khalifa. "It's very realistic. Some people think it's real and feel frightened."

"The glass floor has really added a new dimension to the At the Top experience for the visitors," Bakhrani said. "There are a number of high-tech attractions that together make a visit to Burj Khalifa truly unforgettable. This is a world-class venue, so it's essential that everything that’s done adds to the exhilaration of being there, and it’s certainly been achieved with the glass floor."

Installation of the project took around two months, working between 1am and dawn, when the building is closed to visitors. The screens are regularly cleaned throughout the day.

LG, BrightSign, and DigiComm have previously collaborated on numerous projects, including a shark experience at the Dubai Aquarium and Underwater Zoo that combines digital technology with live fish.

Toronto’s CN Tower, Canada’s National Tower, has released the new CN Tower Viewfinder app, which is designed and developed by Fuzz Productions in Brooklyn, NY. Created to enrich the experience of on-site visitors, the app represents the first and only attraction in Canada to offer a virtual reality observation experience at 1,136 feet.

The app celebrates the City of Toronto’s skyline from the perspective of the newly renovated observation level at CN Tower and features spectacular 360-degree day and night panoramic images. Guests with the app can identify various points of interest across the city and can now answer the question “What am I looking at?” from their own iPhone or Android mobile device.

“As a Canadian icon, we are always looking to expand our digital engagement with our guests from all corners of the world,” said Joanne Pawlicki, director, marketing and communications for CN Tower.

“Through leveraging emerging 3D and virtual reality technologies, the new Viewfinder app enhances guest experience and greater interaction with Toronto’s skyline,” said Kevin McManus, CN Tower‘s director of information technology. “It is also complementary to the CN Tower Experience app, launched in June 2016.”

As part of CN Tower’s unveiling of the newly renovated observation experience, the new Viewfinder app further launches it into a new echelon of digital tourism. Designed and developed by Fuzz Productions, the app calibrates a user’s location on the observation level using the phone’s internal sensors that behave like a gyroscope. This pinpointed calibration allows guests to scan the Toronto skyline and discover over 90 landmarks and points of interest, including architecture, entertainment, and geography. Reflecting the diversity of its guests, the app supports five languages: English, French, Spanish, Korean, and Mandarin. The app is available as a free download at the App Store and Google Play.

“Fuzz couldn’t be more excited to work with CN Tower on a 3D immersive experience in the new Viewfinder app,” said Nat Trienans, CEO and co-founder of Fuzz. “It both enhances the CN Tower visitor’s experience as a digital tour guide to the Toronto skyline, and allows everyone around the world to enjoy the incredible views from CN Tower right on their mobile.”

Future considerations include exploring the addition of Augmented Reality (AR) capabilities by harnessing the soon to be released iOS 12, which includes Apple’s new AR development toolkit. CN Tower plans to also add additional features such as detailed descriptors for each landmark and evaluate capabilities to share postings to social media sites.
