UNIT 1- Introduction to Augmented and VIrtual Reality || AKTU Notes

History of Virtual Reality Virtual and augmented reality (VAR) is not a new concept, but over the past couple of years, these technologies have become more accessible to the public, and libraries are at the forefront of this access. Virtual reality is described as an experience that encompasses most of the senses, including sight, hearing, and touch, and represents an alternative to reality. The concept of virtual reality has made appearances in media going back almost a half century, usually shown as a futuristic plot device in books such as Ender’s Game by Orson Scott Card, or films like The Matrix . Thanks to advances in technology, the fictional virtual reality is coming close to actual reality. While virtual reality has been used in the private sector for a while, it has just recently become available to the more general public through a variety of devices for home use that have been released onto the market. The origins of the concept of virtual rea...

UNIT-2 3D USER INTERFACE INPUT HARDWARE

Introduction This chapter continues our discussion of the hardware commonly used in 3D UIs. We examine a variety of input devices that are used in both immersive and desktop applications and their effect on 3D UIs. We also examine how to choose input devices for different 3D applications by looking at some important device attributes, taxonomies, and evidence from empirical studies. Roadmap For 3D UIs Discussion of a variety of different input devices used in 3D interfaces and how they affect interaction techniques. These devices are broken up into the following categories: desktop input devices input device characteristics tracking devices 3D mice special-purpose input device direct human input Desktop Input Devices Many input devices are used in desktop 3D UIs. Many of these devices have been used and designed for traditional 2D desktop applications such as word processing, spreadsheets, and drawing. However, with appropriate mappings, these devices also work...
