The Graph Mapping project is a software framework for interoperating heterogeneous applications in mobile environments.
This is accomplished via lossy graph mappings, which, together with cost evaluation modules, allow the transformation of structure documents between disparate platforms. We have applied the framework in collaborative graphics applications that use XML documents to represent the data. The OpSIM project consists a series of algorithms for Optimal Tree Simplification, and a software architecture to apply this into mobile graphics. The central idea of optimal tree simplification is to be able to obtain a simplified version of a tree data structure (used widely in graphics applications), given the available resources, such that the fidelity as perceived by the user is maximized. We have developed a series of algorithms that solve this problem optimally and sub-optimally, and we have implemented a software architecture that allows the exploration of different tradeoffs, algorithms and constraints in mobile VR. DISCIPLE (DIstributed System for Collaborative Information Processing and LEarning) is a project in mobile computing and collaboration. The key objective of the DISCIPLE project has been to develop an advanced groupware design that enables interactive collaboration in the context of the task at hand. The participants at different locations collaboratively access, manipulate, analyze, and evaluate multimedia data. They may have different preferences for data presentation and system interaction and may use unlike computing devices and communication technologies. The system uses intelligent knowledge-based strategies to reduce the effect of differences and thus provide for equitable and effective collaboration. |
