What is a Virtual Character? • Virtual character - a character who represents the state of a system • In TRON (1982), humans and humans that represents software interacted within a world that represented the hardware.
What is a Virtual Character • We aim to to have humans and human the represent software interact in the real world. r
Virtual Character Research • Mostly • Rendering • Animation • Artificial Intelligence • Newer approaches • Affective power • Human response to VCs • Clinical Psychology • Fear of public speaking
Motivation • “Doctor, I have a pain in my side!” • What you do next depends on: • Age • Gender • Ethnicity • Visual Cues • Audio Cues
Motivation • Current methodologies • Books • Standardized Patients (actors) • Restricted in: • Training frequency • Scenario variety • Immediate feedback • Affects medical student preparedness • Provide additional training opportunities
Solution • Interactive Virtual Characters • Life-Sized • Computer Generated • Natural Interaction • Responds to User • Responses based on accepted medical procedure • COTS Equipment: • Projectors • Laptops • Web cameras • Tablet PC
Why Do We Want Virtual Characters? • Propose: Digital Characters as a new (meta-) medium to interact with information • Effective Interaction • Better than keyboard and mouse for certain tasks • Dynamic • 3D • Natural interaction • Low Bandwidth • Effective Collaboration • Controlled conveyed visual information • Non-verbal communication (60%)
Thinking Digital Character Responding Perceiving Let’s look at interaction • Each participant in a communication has three stages: perception, cognition, and response • Define interaction as both the input and output Digital Character Thinking Responding Perceiving Interaction Perceiving Responding Thinking Participant
Combines • Speech • Computer Vision • Eye Gaze • Gesture Recognition • Repeat your gestures • High Quality 3D models • Animation • Rendering • Visualization
Integrates • Computer Science • Computer Graphics • Image Processing • Natural Language Processing • Medicine • Training • Education • Standardization • Education • Multimedia Learning • Technology based Learning • Training • What other areas could this be used for? • Psychology • Social Science • Education
Current and Future Work • Current Status: • Initial scenario created with gesture, speech, and visualization components integrated • Evaluating with a group of Medical Students Year 2 • Future Work: • Formal evaluation studies • Increase and improve scenarios • Enhance interactivity • Show video
