Do you want to create stunning applications with HoloLens? Are you a developer who is fascinated with Microsoft HoloLens and its capabilities? If so, this is the book for you.
This book introduces and demystifies the HoloLens platform and shows you different ways of interaction with computers (mixed-reality).
You will start your mixed-reality journey by understanding different types of digital reality. You will learn to build your first holographic app. Also, you will understand holographic application integration possibilities within Line of Business Applications using Azure. Moving ahead, you will create Integrated Solutions using IoT with HoloLens. Gradually you'll learn how to create and deploy apps on a device. You will learn to publish application to the store; if you are an enterprise developer, you will also manage and distribute applications for enterprise-enabled or domain-joined HoloLens.
Finally, you will develop an end-to-end realistic holographic app, ranging from scenario identification to sketching, development, deployment, and, finally, production.

Preface
Digital reality brings immersive experiences, such as transporting you to different world or places, making you interact within those immersive, mixing digital experiences with reality, and ultimately, opening new horizons to make you more productive.
The spectrum and scenarios of digital reality are huge; to understand them better, they are broken down into three different categories: Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR).
Microsoft HoloLens is the most powerful mixed reality personal computing Windows device. It allows you to place your digital content in the real physical world, where it matters most to you. This is what is called an MR device, one that tries to blend the real and digital worlds seamlessly and provides new ways to visualize the world beyond the screens.
The boundaries between the real and the digital world start to blur, and you can interact with the digital world in a very similar way to how you would interact with the real, physical world. What is it about HoloLens that makes it stand out from the other devices in this genre? It is the fact that Microsoft HoloLens is the first fully untethered, self-contained computer running on Windows 10. Yes, that's right: no hassle of wires, additional cables, or connections to a computer or additional devices. It is hands-free, self-contained device with a built-in battery.
This book is mainly focused on the building mixed reality application using Microsoft HoloLens. This book doesn't require any prior knowledge about the holographic platform from the reader, and its strength is the simplicity in which the concepts have been presented using sketching, architecting, code snippets, a step-by-step process, and detailed descriptions. This book covers the following:
Understanding what mixed reality is and the possibilities of it
Understanding the process of developing enterprise holographic applications using HoloLens
Learning the application and interaction model for holographic apps
Understanding holographic application integration possibilities within Line of Business application using Azure
Learning by realistic integrated project examples
Learning end-to-end complex integrated solutions using holographic app and Azure
What this book covers
Chapter 1, Digital Reality - Under the Hood, begins your mixed-reality journey by explaining different types of digital realities, their differences, and usage scenarios. Also, it will explain the different market players and how they are different from each other based on their products. This chapter will also introduce you to the immersive HoloLens device and show you how to take a step further with the device.
Chapter 2, HoloLens - the Most Natural Way to Interact, introduces HoloLens as a hardware device. You will get an insight into the different components that make up HoloLens and the technology behind the device, which makes the components work together. This chapter also gives an overview of holograms and ways to interact with holograms with different interaction models. You will also become familiar with HoloLens Application Model and take a step toward developing holographic applications by understanding the team structures and roles required.
Chapter 3, Explore HoloLens as Hologram - Scenario Identification and Sketching, dives into the development process of developing your first holographic application. You will learn about identifying the scenario and the interaction models required within that scenario, such as how the user will interact with gaze, gesture, and other interaction models. You will also learn how to identify 3D Assets and take a quick overview of creating new 3D Assets.
Chapter 4, Explore HoloLens as Hologram - Developing Application and Deploying on Device, further enhances the scene developed in the preceding chapter and adds new life to it by developing different interaction models using scripting, building interaction model scripts, and testing them in Unity3D and holographic emulators. Finally, you deploy the application on a device and test your first holographic application, and visualize hologram interactions with the real world.
Chapter 5, Remote Monitoring of Smart Building(s) Using HoloLens Scenario Identification and Sketching, teaches you how to identify and design real-world integrated scenarios. You will integrate Azure IoT solutions with holographic application and visualize the data feed coming in near real time from the cloud through holograms. You will learn about integration scenario options, architecture, and the interaction models required within this scenario.
Chapter 6, Remote Monitoring of Smart Building(s) Using HoloLens - Developing Application and Deploying on Device, takes you through integration scenario identified in the preceding chapter, shows you how to implement and develop the holographic application, and explain how to integrate it with IoT system hosted on Azure. You will learn how to pull the data from the IoT system and render 3D assets on the holographic application based on the data. In this chapter, you will build interaction model scripts, test them in Unity and emulators, and finally deploy them on a device and test your first integrated application.
Chapter 7, Build End-to-End Retail Solution - Scenario Identification and Sketching, will teach you how to identify and design end-to-end retail solutions. You will sketch a solution to design your home appliances with virtual holograms. Then, you will place an order directly from the holographic application.
Chapter 8, Build End-to-End Retail Scenario - Developing Application and Deploying on Device, will take the retail scenario identified in the preceding chapter and implement and develop its holographic application. It will integrate it with backend services hosted on Azure. You will learn how to pull the data from the backend system, render 3D Assets on the fly, and place an order within holographic application. Here, you will build interaction model scripts, test them in Unity and emulators, and finally deploy them on a device and test your end-to-end retail application.
Chapter 9, Possibilities, outlines the new possibilities and scenarios with mixed reality and HoloLens.
Chapter 10, Microsoft HoloLens in Enterprise, looks at managing enterprise devices, such as adding them onto enterprise domains, managing updates, application distribution, and other device management features, such as managing devices through Microsoft Intune.
What you need for this book
The basic requirements for this book are as follows:

Digital Reality - Under the Hood
Welcome to the world of Digital Reality. The purpose of Digital Reality is to bring immersive experiences, such as taking or transporting you to different world or places, make you interact within those immersive, mix digital experiences with reality, and ultimately open new horizons to make you more productive. Applications of Digital Reality are advancing day by day; some of them are in the field of gaming, education, defense, tourism, aerospace, corporate productivity, enterprise applications, and so on.
The spectrum and scenarios of Digital Reality are huge. In order to understand them better, they are broken down into three different categories:
Virtual Reality
(
VR
): It is where you are disconnected from the real world and experience the virtual world. Devices available on the market for VR are Oculus Rift, Google VR, and so on. VR is the common abbreviation of Virtual Reality.
Augmented Reality
(
AR
): It is where digital data is overlaid over the real world. Pokemon GO, one of the very famous games, is an example of this globally. A device available on the market, which falls under this category, is Google Glass.Augmented Reality is abbreviated to AR.
Mixed Reality
(
MR
