What Is Augmented Reality?

The overlay of computer-presented information on top of the real world

Combines real and virtual realities Interactive in real time Registered in 3D Not the same as “virtual reality”

Augmented vs. Virtual Realities Virtual reality

Immerses the viewer into computer-generated environments

Requires equipment which completely obstructs visual view of physical objects in the real world

  Augmented reality

Augments or adds graphics, audio, and other sensory enhancements to the natural world as it exists

Reality Continuum

Virtual and real environments are at opposite ends of this continuum

AR is closer to the real environment

Historical Background

1957-62 – Morton Heilig, Sensorama 1966 – Ivan Sutherland, head-

mounted display 1975 – Myron Krueger, Videoplace 1989 – Jaron Lanier coined the term

Virtual Reality 1992 – Tom Caudell coined the term

Augmented Reality

Historical Timeline

1994 – Julie Martin, AR Theater 1999 – Hirokazu Kato, AR Toolkit 2000 – Bruce Thomas, ARQuake 2008-09 – Wikitude, AR Travel Guide

and Navigation System 2009 – AR Toolkit ported to Adobe

How Does AR Work?

Requires Internet connection Can be accomplished in two ways by:

1. Looking at a screen showing visible and augmented objects

2. Looking through a device using the generated screen display

Example s: Looking at a Screen Yellow “first down” line Direction of ice hockey puck Giant logos or ads on athletic fields World record lines for swimming

events

Examples: Looking Through Device Creative photography Navigation systems

Technology

Drivers: video games, cell phone apps

Display types:1. Head-mounted, or heads-up, displays2. Handheld displays3. Spatial displays

Head-Mounted / Heads-Up Displays Combines and displays physical

world images and virtual graphical objects

SVGA Head-Mounted Display

Vehicle Heads-Up Display

Handheld Displays

Small handheld computing device Uses global positioning systems

(GPS)

iPhone Applications

Spatial Displays

Nothing to wear and/or carry Uses digital projectors to display

information Marker-based and markerless

devices

AR KeyboardAR Phone Keypad

Why AR Applications?

Wireless mobile devices Anywhere, anytime access State-of-the-art cell phones Available applications

Advertising Applications

Promote products via interactive AR applications

Movie character speaks to you when you pass her outdoor movie poster

City Sites Tour

Marketing Applications

Assist consumers on location with ratings, reviews, and other information

Restaurant search

Social shopper

Industrial Applications

Compare the data of digital mock-ups with physical mock-ups

Provide instructions, specs, and training for mechanics and machine operators

Scientific Applications

Pending / Future Applications Expanding a PC screen into the real

world “Holodecks” Replacement of cell phone and vehicle

navigation screens Virtual everything Virtual gadgetry Subscriptions to group-specific AR feeds Virtual retinal displays AR-enabled contact lenses

NLE Benefits of AR Exposure to learning experiences Connected to many learning opportunities Learn from anywhere and share with anyone Used to enhance collaborative tasks Support of seamless interaction between

real and virtual environments Use of a tangible interface metaphor for

object manipulation Ability to transition smoothly between reality

and virtuality

Instructional Strategies of AR Learning goes beyond space and

time to extend past the current semester Community-Community Interaction

Learners get real time, up-to-date information Aggregation

Learners combine online content with online resources to enhance learning Mash Up

Instructional Strategies of AR Learners apply visualizations (2D

and 3D) to enhance learning Info-Viz

Learners use mobile devices to gain knowledge Mobile learning

Learners use distant network servers for web applications Cloud computing

Drawbacks of AR

Accuracy Large margin of error

Standards No open standards among AR browsers

Availability of AR-capable devices SmartPhones only

Summary What is AR?

The ability to overlay computer graphics onto the real world

What can AR do? Combines real and virtual realities to turn an

empty space into a very rich educational experience

How can AR be used in education? Offers seamless interaction between the real and

virtual worlds, a tangible interface metaphor, and a means for transitioning between real and virtual worlds to create learning opportunities and knowledge connections
