It shares the service oriented architecture with emerging Web service technology, and has many advantages for future robot middleware such as automatic discovery of services and accommodation of dynamic distributed computing environment. However, the UPnP needs some additional features for being used as a robot middleware. This paper discusses them, and presents some requirements when developing a UPnP SDK for robot middleware as well. This paper also presents an experimental result of applying the UPnP to robot components

In this paper, we describe a ubiquitous interactin space that supports rapid context-aware applications reflecting the smart interaction space with dynamic resources and provides a programmable interface in integrated development environment (IDE) in .NET framework.

This geo-referenced content needs to be classified and organized according to user interest for location-based decision-making. In this study, we define a user interest model and propose a method for organizing and presenting content based on the model. Our approach reconstructs geo-referenced content from a variety of sources based on points of interest organized by the user interest model. We present typical cases of using the proposed method, including a theme park resort, personal weather stations, and travel planning to show how the proposed method facilitates user decision-making based on the geo-referenced content.

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.
