Biography
Guoray Cai received his B.E. and M.E. degrees in Electrical Engineering from Tianjin University, China, and his M.A. in Geography from the West Virginia University, and a Ph.D. in Information Science from the University of Pittsburgh. His main research focus is on novel interface technologies that enable more effective use of geospatial information by non-technical users. In collaboration with colleagues from geography, information science, and computer science, Dr. Cai is investigating the use of a collaborative software agent to enable natural, multimodal interface technologies for interacting with large screen geographical information displays as well as supporting collaboration of distributed mobile devices. His investigation is funded by the National Science Foundation's ITR program and Digital Government Research program.
