1 AR/MR Standardization Activities at ISO JTC 1 SC24 4th meeting of International AR Standards Community Basel, Switzerland October Gerard J. Kim Korea University

2 The Needs (1)! Augmented/Mixed reality is becoming widespread! Mobile devices and ubiquitous computing, sensors and displays! Commercialization has started Many active vendors, but no sharable content standards! Evolving technologies! Different underlying architectures! Different views (abstraction levels) 10/23/11 2

3 Wikitude Sekai Camera Layar Scan Search 10/23/11 3

Geography and Points of Interests (OGC/Web3C)! Virtual world (Web3D)! Documents (HTML)!

4 The Needs (2)! Common baseline reference architecture! Consolidation and integration of existing or evolving content standard! Geography and Points of Interests (OGC/Web3C)! Virtual world (Web3D)! Documents (HTML)! Mash ups / Cloud (Script / HTTP / OCCI)! Content Resources (MPEG)! Brand new constructs! Vision-based AR/MR! Location sensor-based AR/MR! New displays (HMD, HUD, Portable projector, )! New content types (haptics, audio, tactile, ) 10/23/11 4

5 About ISO JTC 1 SC24! Computer graphics, Image processing, Environmental Data! Specializes in the standardization of interfaces for information technology-based applications relating to! Computer graphics! Image processing! Virtual/augmented reality/mixed reality! Environmental data representation! Interaction with and visual presentation of information! Working groups for focusing on specific topics! WG6 Multimedia Presentation and Interchange (X3D, )! WG7 Image Processing and Interchange! WG8 Environmental Data Representation (SEDRIS, )! WG9 - Augmented Reality Continuum Concepts and Reference Model 10/23/11 5

Augmented Virtuality Virtual Environment

6 Augmented Reality Continuum?! Medium which combines physical reality and virtual (it s a Continuum) Mixed Reality Real Environment Augmented Reality Augmented Virtuality Virtual Environment HITLab KBS [Paul Milgram s Reality-Virtuality Continuum (1994)]! The boundaries from physical to virtual world are not precise à to support an entire continuum of realities, define the term Augmented Reality Continuum (ARC) 10/23/11 6

7 The Fit! AR/MR contents are implemented as Virtual contents! Video background imported into the virtual space T = T Virtual cam fov = fov f = f! Virtual world representation is the very scope of SC24! X3D is an ISO standards for representing virtual space from SC24 10/23/11 7

8 The Prep! AR/MR Study group has carried out a preliminary study since 2009! Comprehensive survey and analysis of the state of the art in the field! Already have a rough architecture and content model to start with! Has closely worked with the relevant SDO s and researchers! Web3D, OGC, Web3C, Khronos Group, IEEE / ACM,! Has participated in grass root efforts among the industry leaders! International AR Standards Community (led by Christine Perey)! Wikitude, Layar, Nvidia, Fraunhofer/InstantReality,! Balanced look into the! Academic approach into the problem! Practical needs of the industry 10/23/11 8

9 Study Group Findings! Need for making clear and precise terms! Need for and a rough AR/MR reference architecture! Reuse of existing standards and need for extension! Rough but comprehensive content model 10/23/11 9

10 An example reference architecture 10/23/11 10

11 Preliminary File format structure Augmentation: - 2D/3D Constructs (HTML5 + X3D) - Abstract behavior Physical World: - POI definitions (OGC) - Sensored objects (K-Mart) Binding of Augmentation and Physical world (KML/GIST/K-Mart) <!doctype html> <html> <head> <meta charset="utf-8"> <title> </title> </head> <body> <p> </p> </body> </html> Behavior: Script <script type="text/javascript"> function person(lastname,age,eyecolor) { this.firstname=firstname; this.lastname=lastname; this.age=age; this.eyecolor=eyecolor; } myfather=new person("john","doe",50,"blue"); document.write(myfather.age + " years old."); </script> Complicated behavior only using XDOM and WebGL Access cloud servce (JSON) 10/23/11 11

12 Conclusion! The topic may be somewhat specific but highly important, enough to be treated separately! We now have pretty good concensus-ed ideas/directions about:! What to represent! Underlying system architecture! Corresponding file format structure! To do (hopefully by SC24 WG 9)! Exact definition of terms and scopes! Need to work on the right abstraction level and syntax! Work with different standard bodies and industry! Draft standards documents! A WG will be an ideal driving force and focal point! Swift, immediate and focused actions 10/23/11 12

13 First WG9 Workshop! Nov 17, 2011! Seoul, Korea! Since it is an ISO event, national representatives and liaison officers and special invitees can participate! CFP to national bodies have gone out (probably ^^)! Will discuss and decide upon definite future directions and action items with time line! Your input is valuable and welcome! If you are not a national representative, I can communicate your ideas indirectly on your behalf!! gjkim@korea.ac.kr! dxp.korea.ac.kr/sc24-wg9 10/23/11 13
