a) (b) Figure 1: Web annotation example of the 3D user experience with a 3D object using HTML elements: (a) text and video streaming annotation on 3D planet objects in solar system, and (b) changing the camera perspective of solar system Abstract With the development of 3D Web technologies, 3D objects are now handled as embedded objects without plug-ins on web pages. Although declarative 3D objects are physically integrated into web pages, 3D objects and HTML elements are still separated from the perspective of the 3D layout context, and an annotation method is lacking. Thus it is scarcely possible to add meaningful annotations related to target 3D objects using existing web resources. In addition, people often lose the relationship between the target and related annotation objects in a 3D context due to the separation of the content layouts in different 3D contexts. In this paper, we propose a webizing method for annotating user experiences with 3D objects in a 3D Web environment. The relationship between the 3D target object and the annotation object is declared by means of web annotations and these related objects are rendered with a common 3D layout context and a camera perspective. We present typical cases of 3D scenes with web annotations on the 3D Web using a prototype implementation system to verify the usefulness of our approach. * † ‡

With the development of optic technologies, various forms of stereoscopic 3D displays such, as 3DTVs, head-mounted displays, multi-view autostereoscopic displays, and super multi-view autostereoscopic displays, have emerged. However, displays have various characteristics and different implementations and the supply of content and rendering applications cannot keep up with the development speed of the displays. The content production varies and depends on the characteristics of a specific display. To reuse content with various types of autostereoscopic 3D displays with different characteristics, the content or rendering application should be modified for other displays. To resolve these problems, we propose a webizing method for the content and display of super multi-view autostereoscopic systems in the Web environment. The proposed method renders not only 3D autostereoscopic model by WebGL but also existing web pages described by HTML on the Web as super multi-view autostereoscopic 3D system content on the Web. In addition, we propose a JavaScript interface for describing displays to allow developers to access the profile and functionalities of displays through web browsers. This interface helps rendering applications generate monoscopic 3D or N multi-view autostereoscopic 3D content based on a display profile from the same source, also known as one-source multi-use. We present an example of super multi-view autostereoscopic content and display it in a product design conference on the Web using a prototype implementation to verify the usefulness of our approach.
