Service rendering middleware (SRM) based on the intelligent LOD algorithm

In ubiquitous computing environments, the need of contents adaptation and delivery is growing to support multiple target platforms for single source. Since 2D/3D graphics contents deal with a large data set and a high performance, a service adaptation for context changing is required to manipulate graphics contents with a more complicated method in multiple devices such as desktops, laptops, PDAs, mobile phones, etc. In this paper, we suggest a new notion of service adaptation middleware based on service rendering algorithm, which provides a flexible and customized service for user-centric 2D/3D graphics contents. The service adaptation middleware consists of Service Adaptation (SA) for analyzing environments, Service Rendering (SR) for reconfiguring customized services and Intelligent LOD Algorithm for generating an adapted service by processing customized data according to the level of detail. These adaptation services are able to intelligently and dynamically support the same computer graphics contents with good quality, when user environments are changed.
