Current Status

At the current stage, our I-MINDS system is matured in two fronts: (1) enabling technologies, and (2) intelligent technologies. Table 1 shows the multimedia and GUI capabilities of I-MINDS, which constitute its enabling technologies.

Enabling Technologies
Live audio (2-way)
Live video (1-way)
Superimposition of handwriting (MIMIOS) on lecture screen, superimposition of text on archived lecture pages
Automated archival
Multicast/broadcast
Multicharacter forum and chat room (colors and fonts)
Multicharacter e-whiteboard (colors and fonts, exclusive tokens)
Annotation and asynchronous review of archived lectures
Rich and flexible control of system features

Table 2 shows the agent-based implementations of I-MINDS, which constitute its intelligent technologies.

Initelligent Technologies
Text parsing and categorization
User profiling
Reinforcement learning on agent reasoning
Group formation and refinement
Real-time automated evaluation of questions
Real-time tracking of user activities

We have also conducted actual tests of I-MINDS in the classroom in Spring 2005 in CSCE 155 (CS1) at the University of Nebraska. Analysis and results are forthcoming.
