AR/MR Standardization Activities at ISO JTC 1 SC24 4th meeting of International AR Standards Community Basel, Switzerland October 24-25 2011 Gerard J. Kim Korea University
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

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
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 Reality Continuum? � Medium which combines physical reality and virtual (it’s a Continuum) Mixed Reality Real Augmented Augmented Virtual Environment Reality Virtuality 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
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
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
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
An example reference architecture 10/23/11 10
Preliminary File format structure r: Script Behavi vior: <script type="text/javascript"> <!doctype html> Augmentation: : function person(lastname,age,eyecolor) - 2D/3D Constructs <html> { (HTML5 + X3D) this.firstname=firstname; <head> this.lastname=lastname; - Abstract behavior <meta charset="UTF-8"> this.age=age; <title> 예제 문서 </title> this.eyecolor=eyecolor; Phys ysical W Worl rld: : } </head> - POI definitions � <body> (OGC) myFather=new person("John","Doe",50,"blue"); <p> 예제 단락 </p> - Sensored objects � document.write(myFather.age + " years old."); (K-Mart) … </script> </body> Binding o of � � </html> Augmentation a and Phys ysical wo worl rld Complicated behavior only y (KML/GIST/K-Mart) using XD XDOM and We WebGL Access cloud servce (JS JSON) 10/23/11 11
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
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
