증강현실 전시 기술의 적용 사례 및 분석

제1회 전시공학 워크샵 @ HCI Korea, 2013.2.1

Virtual vs. Augmented Reality

Virtual Reality (out there): Puts people in a computer-generated world Augmented Reality (here & now): Puts virtual content in a real physical world

What is Augmented Reality?

P. Milgram's Reality-Virtuality Continuum [94]

R.Azuma's definition on AR [97]combines real and virtualis interactive in real timeis registered in real 3D world


AR ApplicationsPossible ApplicationsConsumer products, furniture, decorationConstruction, houses, apartmentsAugmented ads, packages, productsEntertainment, infotainment, gamesFashion, trends, digital artsSharing by communitiesMaintenance & Repair Medical, training


Augmented Reality

Get video from camera

Estimate position and

orientation of the camera

Render the augmented

scene

Process the interaction

Update the status


Augmented Reality

Components of an AR SystemFusing CG models with real environment


Augmented Reality

AR Toolkit (Kato et al., ISMAR 2000)Marker(s) detected in every image.Camera pose inferred from their appearance.


AR Core: TrackingRequired Math: 3D Tracking for AR3D Geometry, Linear Algebra, Signal/Image Processing, Machine Learning, Numerical Robust Optimization, etc.

What’s Next?How to make AR App’s useful?Beyond the hype:

• Moving from simple gimmicky experiments to real world applicationsCurrent AR experience

• shows generally low social maturity• Is stalling, waiting for breakthrough either technological or conceptual

Impractical AR Useful AR

•3D models placed in a webcam with little or no interactivity

•Connectivity is always ON•The cloud is the computer•Engaging, persistent experience for the user•Layered animation with little or no feedback

•MAR that uses solely GPS, compass, and accelerometer input

•[LBS + SNS + MAR] drawing from networked large DBs with customization features

•Organic ARgraphy: 3D + Informative

•MAR where geo-tagging doesn't serve an everyday purpose


Ubiquitous VRPlatform for DigiLog Experience Augmented Content is a King, then Context is a Queen consort controlling the King!

User participation

Context-awareness

Realistic 3D augmentation

• Multicore/GPGPU• Object

recognition/tracking• Light source estimation• Physics engine• AI engine

• CoI-aware• Environmental context: • User context: knowledge, experience,

preference• Just-in-time visualization

• Interaction• Mash-up authoring• SNS• Extension of human

perception

How to avoiding the fate of VR?"to look for DigiLog, the intersections between the digital world (3D, SNS) and analog world (CoI)”

uniformly distributed” by William Gibson (SF writer)
