Fairy Lights; Holograms that respond to Human Touch

BY KAYLA NOBREGA

 

Holograms as a concept have existed since the 1940’s. Holograms currently exist by a variety of means, each with its own benefits and limitations.

One of the limitations of holograms is that they are not fully interactive. Trying to touch a hologram could interfere with how the lazer is reflecting the image, and so interrupt the holographic image on display.

This limitation has been overcome by a team of Japanese scientists from the Digital Nature Group. Using short lazer pulses at very short intervals, a hologram is created that can be felt. The hologram itself reacts to touch by changing shape or moving away.

Abu Dhabi International Book Fair 2019 Event Activation

BY KAYLA NOBREGA

 

The Abu Dhabi International Book Fair was held at the end of April 2019, and it was Virtuality’s pleasure to partner up with Top Gear Promotions for the Comic Corner.

Visitors arrived at the event and received a booklet that they had to fill up with different things from the stands at the event. Our concept was to allow the exhibit visitors to create their own personalized comic book cover, by taking a photograph of themselves as one of their favourite DC heroes.

Whether they wanted to be Batman, the Joker, or Aquaman; visitors would stand for their photo in front of our booth. The photo was printed and then stuck on their booklets as their very own comic book.

Top Three Trends for Events in Dubai for 2019

BY KAYLA NOBREGA

 

Augmented Reality Games

Keep your guests engaged and entertained with an Augmented Reality Game. Guests will scan a trigger through a customized application on a mobile device – iPads are the most popular due to their size and AR compatibility – and the Augmented Reality game is activated on the screen.

The game can any the brand and any activity that promotes the product, service, or value that is being launched, taught, or promoted. For an example, have a look at what Abu Dhabi Ports did for Abu Dhabi Innovation Week 2019.

Virtual Reality Tours and Experiences

Creating a Virtual Tour or Virtual Reality brand experience is a highly interactive way to engage with event visitors. It is a good way to introduce your audience to an aspect of your brand that they are not commonly able to experience.

For example, you can take a tour around different wine farms in South Africa at a wine tasting event in France. Just put on the Virtual Reality headset and be transported to where the wine is made.

Holographic Displays

At events where there are speeches and presentations being given, new ways are being sought to keep guests entertained without losing the point of the message.

Interactive holograms, pre-programmed to co-ordinate with the spoken content, are a practical and entertaining way to present information to your audience. While a presenter speaks, animated visuals are displayed on stage via a screen.

What is Indoor Navigation? – Part 2

BY NAIRAH THAHA

 

There are two things required to make an indoor AR location app:

  1. Beacon Technology:

This method entails placing Bluetooth Low Energy beacons (BLE) around the areas you wish to have mapped out. These beacons are small in size and easy to hide. Whenever the user walks into the range of the beacon, it sends out a signal to the AR app via Bluetooth which alerts the software to the position of the user.

The advantage is that the accuracy of the navigation is high since the app is being fed direct information. The cost of creating such a service goes up when you want to cover larger spaces indoors as you will need a lot of sensors.

  1. AR Technology:

If you have used an Augmented Reality app that makes use of ARKit/ARCore frameworks, you would have noticed that once you place 3D content on to a surface, you are able to walk away from it and see that its location persists in the real world. This is done by making use of motion tracking technology using the sensors mentioned above so that it is able to establish how far you have walked and in which direction.

Harnessing this technology, we are able to make indoor navigation apps in Augmented Reality using only sensors. What must be considered, though, is that because of the high frame rate of the sensors small measurement errors can accumulate over time to cause a significant error referred to as “sensor drift.”

The other thing to keep in mind is that the phone needs to be aware of the initial starting point and orientation in order to establish its position. This can be done in many ways, but most commonly users will be asked to scan a predefined image target which lets the app know the initial position and rotation of the phone.
