  1. Applications Architectural design Mechanical design GUI design Animators Maps & geographical information Software engineering (UML) Note-taking Sketching devices Digitizing tablet (Wacom) PDA Tablet PC Board + ultrasonic emitters Phantom AAAI Spring Symposium: Sketch Understanding Workshop • Topics • Early stages • Applications • Recognition • Tools • Cognitive issues

  2. 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 user’s 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

  3. Best Work • Ellen Do – Architecture; Univ. of Washington http://dmg.caup.washington.edu • Fonseca et al. – Trainable recognizer; Tech. U. of Lisbon http://immi.inesc-id.pt/cali/ • Randy Davis – Simulate a mechanical sketch; MIT • James Landay – GUI Design; UC Berkeley • Mahoney & Saund – Graph representation; PARC • Ken Forbus & Ron Ferguson – Maps; Northwestern • Barbara Tversky – Cognitive issues (maps); Stanford • Phil Cohen & Sharon Oviatt – QuickSet (maps); OGI http://www.cse.ogi.edu/CHCC/Personnel/pcohen.html
