W3C Workshop 2010 - W3C Workshop: Augmented Reality on the Web

Augmented reality (AR) is a term for a live direct or indirect view of a real-world environment whose elements are supplemented with, or augmented by computer generated imagery. The augmentation is conventionally achieved in real time and in a meaningful context with environmental elements.
Augmented reality is a long standing topic in its own right but it has not been developed on the Web platform. Currently there are diverging technologies for AR with few widely-accepted standards in sight: this is a recipe for customer confusion and industry gridlock.
Can the new interaction paradigm of AR be integrated into the platform of the Web and, if so, how? More importantly, how can AR itself evolve to become as open and inclusive as the Web?
There are many emerging W3C standards including geolocation and camera APIs together with cross-platform, non-proprietary widgets. These are all relevant but what other standards are needed for open AR? Data formats?
The objective of this W3C workshop Augmented Reality on the Web is to provide a single forum for researchers and technologists to discuss the intersection of AR and Web technologies, particularly as used on the mobile platform, and to explore what role standardization should play for Open Augmented Reality.
The workshop is closely associated with the MobEA series, now in its eighth year.
Topics of Interest

The main topics of interest for the envisioned workshop contributions include (but are not limited to) the following:
Web and AR
How does Web content need to evolve with AR (e.g. extensions to current Web technologies like CSS to support AR)?
How might Web browsers need to evolve to become AR platforms?
Are the current and planned device APIs sufficient to enable the Web to be used as an AR platform?
Can the 3D Web be an effective platform for AR?
Is the infrastructure in place to support AR on the Web?
What are the potential synergies between between AR and Virtual Reality?
Is there sufficient royalty-free, interoperable data available to make AR on the Web a reality?
User interfaces
3D interaction and gestural interface and how these interfaces map onto the Metaphor of the Web.
How far can we stretch advanced UI techniques (e.g. 3D navigation) for building more immersive applications?
What opportunities are offered by advanced display and immersive projection technology?
What opportunities are there for innovative interaction such as haptics, audio, and other non visual interfaces?
Mobile AR
What are the existing and emerging mobile AR development environments and toolkits?
Are mobile tracking & sensing sufficient for AR?
How can mobile presence and cognition be exploited by AR?.
What are the latest developments in mobile widgets and mashups for AR?
Can AR play a role in media adaptation and content filtering?
Evaluation of AR
What user studies and evaluation is relevant to AR?
What are the existing standard datasets and benchmarks for AR? (if any).
Where are the gaps in the datasets and benchmarks that need to be filled for AR to become more widely available?
What does an AR Web site look like for the visually disabled and what extensions would be required to current Web Accessibility techniques?
...
Standardization
Is there a need for a common infrastructure for points of interest (such as common code/reference, a common database etc.)?
What are the available languages for "augmenting" points of interest and what more may need to be standardized?
What is the relationship between AR and linked data?
