Overview of this book

Are you a developer who is fascinated with Microsoft HoloLens and its capabilities? Do you want to learn the intricacies of working with the HoloLens SDK and create your own apps? If so, this is the book for you. This book introduces and demystifies the HoloLens platform and introduces new ways you can interact with computers (Mixed Reality). It will teach you the important concepts, get you excited about the possibilities, and give you the tools to continue exploring and experimenting. You will go through the journey of creating four independent examples throughout the book, two using DirectX and two using Unity. You will learn to implement spatial mapping and gesture control, incorporate spatial sound, and work with different types of input and gaze. You will also learn to use the Unity 5 SDK for HoloLens and create apps with it. Collectively, the apps explore the major concepts of HoloLens, but each app is independent, giving you the flexibility to choose where to start (and end).

Project setup


Just to recap, the example for this chapter is about performing facial recognition and tagging the recognized person's name (or alias) into the scene. In this section, we will walk through setting up the Microsoft Cognitive Service, which will be responsible for facial detection and identification as well as preparing the dataset that we will use to perform facial identification, that is, photos of people you would like the service to recognize.

We will use one of the Cognitive Services Microsoft services, called Face API, from Face API. As the name implies, the service is orientated around detecting and identifying faces but also allows for some interesting metadata, such as the following:

  • Age
  • Gender
  • Likelihood of smiling
  • Wearing glasses
  • Emotion (a measurement of happiness, sadness, and anger, along with many others)
  • Presence of facial hair

Before you can make use of the service, you must register (if not done so already) an Azure account and add the service to your portal, details...
