Education Databases and Interfaces: Even today's primitive education development tools are already creating a flood of new content in the form of: streaming media modules; visualization applets; problem and laboratory databases; video, audio, and other multimedia databases; and many other classes of knowledge and learning objects. All of this new information has the potential to revolutionize education delivery, addressing the needs of many different learning populations in highly targeted ways. The problem, of course, is the exponentially increasing complexity of the associated educational environment. If all of this potentially useful data cannot be navigated and utilized in a reasonable fashion by student and teacher alike, then the advantage is lost.
The research areas currently being pursued include: smart agents; automatic construction of FAQs; knowledge management for distributed learning environments; visual information management for interactive learning environments; indexing of multi-component artifacts; topic-based visualization of large heterogeneous collections; automatic video indexing, adaptive agent-based tutoring systems and learner modeling; XML/meta-data representations of content; automatic audio indexing; multimedia recognition (speech, image, video, facsimile); distributed indexing of heterogeneous archives; course authoring tools (CourseComposer and inFusion Course Builder, and Connexions); and collaborative filtering applied to learning models.

Very Low Bit Rate Education Delivery: The wave of technology that is now breaking over higher education is streaming media. The bandwidth required for the "high quality" streaming media lecture modules currently in use at Georgia Tech is about 100 Kbps. This makes online delivery reasonable only for broadband networks. The interesting question being pursued at the CDEE is "what would the world be like if we could deliver effective educational materials at a much lower bandwidth, say 5-10 Kbps?" Such a low bandwidth requirement would enfranchise huge, currently underserved, populations - nationally and worldwide. Also, such "cell phone" data rates would allow ubiquitous educational connections using wireless PDAs. Most importantly, perhaps, the underlying network requirements for access, storage, and transport would be tremendously reduced.
In this area, an intense study of what is educationally effective is being combined with an intense study of what is technologically possible. The research being pursued in this area includes: camera-based recording of white board lectures; device dependent educational delivery; personalized content delivery; inFusion for PDAs; lip and head tracking for low-bit-rate video; facial feature analysis and synthesis; speech coding for wireless handheld devices; compression of graphical notes; and image and video networks.

  • Infusion for PDAs
  • Lip and Head Tracking for Low-Bit-Rate Video
  • Architectures for Very Low Bit Rate Real-Time Video Compression
  • Facial Feature Analysis And Synthesis (FFAAS)
  • Speech Coding for Wireless Handheld Devices
  • Audio Signal Enhancement and Noise Suppression for Compression


Tele-Presence for Education Delivery and Collaboration: It is tempting to hypothesize that high bandwidth alone can solve many of our educational problems by allowing widely distributed groups to communicate as if they were all together. However, even ignoring questions of appropriateness and cost, this vision is currently not technologically achievable since we do not know enough about how technology can be effectively used to communicate among widely distributed populations in dissimilar facilities. The fundamental issue is how to collect, process, and deliver appropriate video, audio, and multimedia data so that geographically distributed participants can communicate as effectively and as naturally as if they were in the same room.
Of course, tele-presence issues are not unique to education, and there is a substantive research effort in this area already underway at Georgia Tech. The CDEE's role is to allow these efforts to be focused and brought to practice through educational applications. The research areas being addressed by the CDEE include: location dependent educational delivery; device sharing and collaboration using handheld devices; in-class mobile device use; context sensitive note taking; educational tools for the handicapped; distributed archiving of tele-presence content; adaptive mixing for acoustic de-reverberation; synchronous remote whiteboards; acoustic noise suppression for audio capture in classroom environments; acoustic source localization; multiview imaging for digital tele-presence; Differentiated Services (DiffServ) for support of Quality of Service (QoS); and IP Multicast for multi-point interaction.
