One problem that a 2D graph has might be its ambiguity in conveying information about volume. How many pizzas does America consume in a year How much garbage does a person produce in a year on average It is hard to tell when you look at bars on a bar chart. However, in a virtual reality environment you can see the pizzas stacked up together and the garbage piled up around you. When representing volume, virtual reality is able to give the audience a real sense of how large or how small the data is.
Also, the immersive experience in a virtual reality environment can be more effective in evoking emotions of the audience. Imagine the astonishment walking across towers of pizzas piling up around you, or standing on top of a pizza tower and looking down to the ground. The emotions evoked by simply looking at the data representation may help the audience to stay with the data for a longer time.
Like other 3D environments, virtual reality adds a third dimension to the 2D surface, which makes it possible to convey multiple data layers in a single data visualization piece. Think about representing the comparison between different data sets and at the same time showing the change over time. It would not be as clear when such information is shown on a 2D graph, but it can be when depth is added to the representation in virtual reality.
In 2D graphs, the best way to show change over time is probably a line graph, but with one more dimension in virtual reality, a lot more options are provided to show change over time more effectively. Change of environment, animation of a heat map etc. can provide the audience with more direct impression of how the the data changes over a certain time period.
Through our research and prototype-based exploration of VR data visualizations, we have found many ways in which virtual reality provides a unique and valuable aspect to data visualization. To reiterate, these are some of the main instances where VR is an ideal way to visualize data:
You'll delve into the basics of Unity and get familiar with Unity assets, materials, and resources, which will help you build a strong foundation for working on the different AR projects covered in the book. You'll build real-world projects for various industries such as marketing, retail, and automation in a step-by-step manner. This will give you hands-on experience in developing your own industrial AR apps. While building the projects, you'll explore various AR frameworks used in the enterprise environment such as Vuforia, EasyAR, ARCore, and ARKit, and understand how they can be used by themselves or integrated into the Unity 3D engine to create AR markers, 3D models, and components of an AR app.
AR is the term that's used to describe the technology that allows users to visualize part of the real world through the camera of a technological device (smartphone, tablet, or AR glasses) with virtual graphical information that's been added by this device. The device adds this virtual information to existing physical information. By doing this, tangible physical elements combine with virtual elements, thus creating augmented reality in real-time. The following image shows how AR works:
Now, you have a better grasp of what AR is and where it comes from. We have covered the basics of AR by looking at the first prototypes, and classified different types of AR according to the element that triggers the virtual images so that they appear on the screen. The next step is to see what is required to work with it.
The result is an interface in which reality is observed with additional information located in the space it needs to be in. The following subsections present different AR libraries and SDKs, as well as how they function.
ARToolKit was the world's first open source software library and allows the creation of AR applications, in which virtual images overlap in the real world. It uses video tracking capabilities to calculate the position of the camera and the orientation relative to the position of the physical markers in real-time. Once the position of the real camera is established, the virtual camera is placed at the same point and a virtual layer of information, such as a 3D object, is superimposed on the real marker. ARToolKit was originally developed by Hirokazu Kato and the initial release was published in 1999 by the HIT Laboratory of the University of Washington. It is currently maintained as an open source project hosted at SourceForge with commercial licenses available at ARToolworks:
Apple launched the first version of ARKit in 2017, along with Xcode 9 and iOS 11, to bring AR to iOS devices. The framework, which is included in Xcode, lets users place virtual content in the real world. Months after its official release, it added new features such as 2D image detection and face detection. In 2018, with the iOS 12 release, ARKit 2 was launched with new features such as 3D object tracking, adding realistic textures to the scenes, and creating multiuser AR experiences. At the time of writing this book, the latest version is iOS 13, with ARKit 3 promising a huge improvement on the current state as it will add a new way of interacting with virtual elements, such as hiding virtual objects when a person is detected in front of them. It also allows users to interact with 3D objects via gestures and capture not only facial expressions but the body motions of a person.
Thanks to AR technologies, you can create a virtual and dynamic replica of a real system, product, or service that, through the information that's obtained from sensors or automatisms, models its behavior. In this way, it allows intelligent monitoring and analysis, as well as the realization of simulations and experiments in the replica, without risks or costs, with the aim of improving the performance and effectiveness of the real system.
Using AR, the user is in charge of their experience and can interact with it. Now, brands go beyond the wow effect and create functional experiences to promote and sell their products. Examples of this include augmented catalogs, which show the products in 3D over their flat images; virtual mirrors, where you can buy the glasses or complements you are trying on AR; packages that come to life to explain the elements inside the fabrication process; and so on.
The thing that's attractive about AR is the visual content it displays over the real world. That makes this technology perfect for enhancing traveling experiences, from showing skyline information to making animals in a museum come to life or even translating signs and guides in real-time. Some of the most common uses of AR in tourism include serving as a live guide in the streets of a new city, where a user can go around the city while the AR app is showing them where the most interesting points to see are; showing attractions and points of interest (POIs) over a map when a user points at a map with the camera; giving all kinds of extra information on paintings, sculptures, or monuments so that when a user points at a painting it can show a video about the author, the place and time where it was painted, or even make it come to life in a 3D simulation. Apart from all these experiences, when AR is combined with other immersive technologies, such as virtual worlds or 360º videos, the experience goes one step ahead, allowing users to visit several places at the same time (for example, in a museum network, while visiting one of them, to be able to virtually visit the others).

Hey I just bought it but I can't seem to get it to work with my WMR headset. When I launch it steamvr crashes instantly or the game enters VR mode but displays on my monitor and nothing works. Is there some sort of launch procedure
