Current Research Issues

• Cognitive Science How do people use sketches
• What do people extract from sketches
• When to recognize precisely when to be
  approximate
• Computer Vision Sketch capture
• Better recognition, segmentation, focus of
  attention
• Recognizing crisp sketches vs. messy sketches
• AI How to infer represent the users intent
• Representation, semantics, reasoning
• HCI
• Building a seamless interface, Combining
  multi-modal inputs
• Creating, editing communicating sketches
• Software Architecture
• Low level processing vs. domain-specific plug-ins
• Common toolkits, Building an infrastructure
