Overview of this book

The drastic surge in the demand for XR development has led to an imminent need for comprehensive resources, learning material, and overall know-how in this area. This one-stop resource will ensure that professionals venturing into XR development can access all XR-related techniques to build appealing XR applications, without relying on Google every step of the way. This book is your guide to developing XR applications with Unity 2021.3 or later versions, helping you to create VR, AR, and MR experiences of increasing complexity. The chapters cover the entire XR application development process from setting up an interactive XR scene using the XR Interaction Toolkit or AR Foundation, adding physics, animations, continuous movement, teleportation, sound effects, and visual effects, to testing and deploying to VR headsets, simulators, smartphones, and tablets. Additionally, this XR book takes you on a journey from the basics of Unity and C# to advanced techniques such as building multiplayer applications and incorporating hand- and gaze-tracking capabilities. By the end of this book, you'll be fully equipped to create cutting-edge XR projects for engaging individual, academic, and industrial use cases that captivate your audience.

Interacting with objects in XR experiences via eye- or head-tracking

In this section, you will not only learn about eye-tracking itself and how it can enrich your XR experience, but you will also implement eye-tracking functionalities to your XR experiences, regardless of whether your VR headset supports eye-tracking or not.

Understanding eye-tracking and potential use cases

From reading a person’s intent to enhancing digital interactions, eye-tracking technology is revolutionizing how technologies of all kinds perceive and interpret human behavior.

The eyes are often dubbed the “windows to the soul” due to their ability to express and convey emotions, intent, and attention. Biologically speaking, several key aspects of the eyes play into this:

  • Pupil dilation: Often a subconscious response, the pupils can dilate or contract based on emotional states, levels of attention, or reactions to stimuli. For instance, someone’s pupils might dilate...
