SUMMARY:Brown bag: Siddhartha Chaudhuri
DESCRIPTION:Title: The Semantics of Shape\nSpeaker: Siddhartha
	 Chaudhuri\nAbstract: Visual media surrounds us\, and there is growing
	 interest in new applications such as 3D printing and collaborative
	 virtual worlds. As more and more people engage in producing visual
	 content\, there is a demand for interfaces that help novice users carry
	 out creative design. Such an interface should allow people to easily and
	 intuitively express high-level design goals\, such as \"create a cute
	 toy\" or \"create a comfortable chair\"\, while allowing the final
	 product to be customized according to each person's
	 preferences.\n\nCurrent interfaces require the design goal to be reached
	 through careful planning and execution of a series of low-level drawing
	 and editing commands -- which requires previsualization\, dexterity and
	 time -- or serendipitiously through largely unstructured exploration.
	 The gap between how a person thinks about what he wants to create\, and
	 how he can interact with a computer to get there\, is a barrier for the
	 novice.\n\nIn this talk\, I will present recent work on capturing
	 high-level design intent to aid the creative process. The crux of our
	 work is studying the semantic identities of shapes\, not just their
	 geometric descriptions. We analyze large classes of three-dimensional
	 objects from three perspectives: structure\, attributes and interaction.
	 We study how objects are constructed from components (\"chairs combine
	 seats\, backs and legs\")\, how they can be described using continuously
	 varying natural language attributes (\"this chair is more elegant than
	 that one\")\, and how their functional design depends on human
	 interaction (\"how we sit on an armchair is different from how we sit on
	 a kitchen chair\"). Our work combines probabilistic shape analysis\,
	 machine learning and crowdsourcing. The approaches are data-driven:
	 large repositories of existing designs are used to learn shared
	 semantics\, and repurposed for synthesizing new designs.\n\nI will
	 conclude with a discussion of directions\, opportunities and challenges
	 for new tools for high-level design that exploit the inter-relationship
	 of semantics\, function and form.
