2. electronic visualization laboratory, university of illinois at chicago The Electronic Visualization Laboratory Established in 1973 Jason Leigh, Director; Tom DeFanti, Co- Director; Dan Sandin, Director Emeritus 10 full time staff Interdisciplinary Computer Science, Art & Communication 30 students, 15 funded students, Research in: –Advanced display systems –Visualization and virtual reality –High speed networking –Collaboration & human computer interaction 34 years of collaboration with Science, Industry & Arts to apply new computer science techniques to these disciplines. Major support by NSF and ONR.

3. electronic visualization laboratory, university of illinois at chicago Goal in 3 Years Life-sized Avatar capable of reacting to speech input with naturalistic facial and gestural responses. A methodology of how to capture and translate human verbal and non- verbal communication into an interactive digital representation. Deeper understanding of how to create believable/credible avatars.

4. electronic visualization laboratory, university of illinois at chicago System Components AlexDSS Speech Recognition Natural Language Processing Responsive Avatar Facial Expression Recognition Responsive Avatar Engine Eye-tracking Speech Synthesis Lip Synch Gestural Articulation Facial Articulation Knowledge Processing Facial & Body Motion / Performance Capture Phonetic Speech Sampling Knowledge Capture Textual & Contextual Information

5. electronic visualization laboratory, university of illinois at chicago EVL Year 1 Digitize facial images and audio of Alex Shadow Alex to capture information about his mannerisms Create 3D Alex focusing largely on facial features Prototype initial RAE & merge initial avatar, speech recognition, AlexDSS, pre-recorded voices Validate provision of non-verbal avatar cues, evaluate efficacy of cues

6. electronic visualization laboratory, university of illinois at chicago EVL Year 2 Full-scale Motion & performance capture to create gestural responses to AlexDSS Speech synthesis using Alex’s voice patterns to create verbal responses to AlexDSS Use eye-tracking to begin to experiment with aspects of non- verbal communication Evaluate merging of verbal and non- verbal information in users’ understandings of –avatar believability and credibility (ethos) –information retrieved –avatar emotional appeals (pathos)

7. electronic visualization laboratory, university of illinois at chicago EVL Year 3 Utilize camera-based recognition of facial expressions as additional non-verbal input Conduct user studies: –relative to a believability and credibility (ethos) –to correlate attention to non- verbal communication relative to comprehension and retention –to assess value of avatar emotional appeals (pathos) –to address formation of longer-term relationship formation between avatar and user.
