Unity Virtual Reality Projects - Second Edition

By: Jonathan Linowes

Overview of this book

Unity has become the leading platform for building virtual reality games, applications, and experiences for this new generation of consumer VR devices. Unity Virtual Reality Projects walks you through a series of hands-on tutorials and in-depth discussions on using the Unity game engine to develop VR applications. With its practical and project-based approach, this book will get you up to speed with the specifics of VR development in Unity. You will learn how to use Unity to develop VR applications that can be experienced with devices such as Oculus, Daydream, and Vive. Among the many topics and projects, you will explore gaze-based versus hand-controller input, world space UI canvases, locomotion and teleportation, software design patterns, 360-degree media, timeline animation, and multiplayer networking. You will learn about the Unity 3D game engine via the interactive Unity Editor, and you will also learn about C# programming. By the end of the book, you will be fully equipped to develop rich, interactive VR experiences using Unity.

Managing VR motion sickness

VR motion sickness, or simulator sickness, is a real symptom and a concern for virtual reality. Researchers, psychologists, and technologists with a wide array of specializations and PhDs are studying the problem to better understand the underlying causes and find solutions.

A cause of VR motion sickness is a lag in screen updates, or latency, when you're moving your head. Your brain expects the world around you to change exactly in sync. Any perceptible delay can make you feel uncomfortable, to say the least.

Latency can be reduced by faster rendering of each frame, keeping to the recommended frames per second. Device manufacturers see this as their problem to solve, in both hardware and device driver software. GPU and chip manufacturers see it as a processor performance and throughput problem. We will undoubtedly see leaps and bounds of improvements...
