Welcome to the Virginia Tech Superimposed Information (SI) Projects webpage! We are working on two projects involving SI:
Sidewalk is a collaborative research project, funded by the National Science Foundation through the National Science Digital Library services track. Our research partners in this project include Portland State University, and Villanova University.
Superimposed information refers to new information laid over existing information. Annotations, bookmarks, references, knowledge management tools, etc., all come under the purview of SI. The focus of our work has been to enable users to work with information at the level of sub-document granularity - for example, 3 lines in an article, a face in a photograph, an audio/video clip. Along with our collaborators, we have built software prototypes that allow users to work with superimposed information and use it in annotation and knowledge management tasks. We have conducted pilot user studies on some of the tools and have received some positive feedback. This poster gives an overview of our work. Currently, we are working on a formal representation for SI concepts in a digital library context, as well as more user studies to evaluate the use of SI tools in scholarly tasks.

This is a collaborative project with Dr Eric Hallerman with the Fisheries and Wildlife Sciences Department at Virginia Tech and Dr Ricardo Torres with the Institute of Computing, University of Campinas, Brazil (UNICAMP). This project is funded by Microsoft Research under the Tablet PC Technology and Higher Education program.
We are deploying and assessing a Tablet PC image annotation and retrieval tool that will help scholars work with images and parts of images; associate them with multimedia information such as text annotations made with an electronic pen, or audio or video content; and, later, retrieve information based on text- and/or content-based image retrieval techniques. As part of the project, we plan to evaluate the tablet PC tool in Fisheries and Biology classes at Virginia Tech and UNICAMP.
