2 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

3 What is Augmented Reality? P. Milgram's Reality-Virtuality Continuum [94] R.Azuma's definition on AR [97] combines real and virtual is interactive in real time is registered in real 3D world

4 AR Applications Possible Applications Consumer products, furniture, decoration Construction, houses, apartments Augmented ads, packages, products Entertainment, infotainment, games Fashion, trends, digital arts Sharing by communities Maintenance & Repair Medical, training

5 Augmented Reality Get video from camera Update the status Estimate position and orientation of the camera Process the interaction Render the augmented scene

6 Augmented Reality Components of an AR System Fusing CG models with real environment

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

8 AR Core: Tracking Required Math: 3D Tracking for AR 3D Geometry, Linear Algebra, Signal/Image Processing, Machine Learning, Numerical Robust Optimization, etc. Range of Techniques

9 응용사례 고정시점 & 센서기반트레킹 이동시점 & 센서기반트레킹 고정시점 & 영상기반트레킹 이동시점 & 영상기반트레킹

10 응용사례 ( 이동시점 & 영상기반 )

11 응용사례 (UVRLab)

12 What s Next? How to make AR App s useful? Beyond the hype: Moving from simple gimmicky experiments to real world applications Current AR experience shows generally low social maturity Is stalling, waiting for breakthrough either technological or conceptual Impractical AR 3D models placed in a webcam with little or no interactivity Layered animation with little or no feedback MAR that uses solely GPS, compass, and accelerometer input MAR where geo-tagging doesn't serve an everyday purpose Useful AR Connectivity is always ON The cloud is the computer Engaging, persistent experience for the user [LBS + SNS + MAR] drawing from networked large DBs with customization features Organic ARgraphy: 3D + Informative

13 Ubiquitous VR Platform for DigiLog Experience Augmented Content is a King, then Context is a Queen consort controlling the King! How to avoiding the fate of VR? "to look for DigiLog, the intersections between the digital world (3D, SNS) and analog world (CoI) 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 Contextawareness User participation Interaction Mash-up authoring SNS Extension of human perception
