The Design Intelligence Laboratory (DIL) conducts research in design cognition, design AI, and design computing. Our work on emphasizes multi-modal, knowledge-based techniques of reasoning and learning in design, including functional modeling, analogical reasoning, visual reasoning and meta-reasoning. Creative design of physical systems and design of self-adaptive software agents form the context for much of this research.
The long-term, big-picture questions that drive our research are: (1) What is creativity in design, how may we build computer systems that can generate creative designs, and how might we build interactive environments to aid human creativity? (2) What is reflection in intelligent agents, how may we design software agents that can reflect on their knowledge, reasoning, and behavior, and how might reflection enable self-adaptation and self-explanation? (3) What is visual reasoning in design cognition, and how may we build interactive environments and tools that use the human capacity for visual reasoning?
From the viewpoint of design, we develops theories, techniques and tools that enable innovative design of physical systems and design of self-adaptive software agents. The goals of the research on conceptual design of physical systems (e.g., biologically inspired engineering design) is to develop theories of creativity in design and to build interactive tools for aiding innovative design. The goals of the research on design of self-adaptive software agents (e.g., game-playing agents) is to develop theories of reflection in intelligent agents, and to build interactive tools for supporting adaptations to designs of software agents.
From the perspective of artificial intelligence, we develop theories and techniques of functional modeling, and analogical, visual and meta-reasoning that provide unified accounts of memory, reasoning and learning, and integrated accounts of the content/representation of knowledge and the processes of reasoning/learning. Results of this research are in the form of architectures, processes, methods and algorithms for reasoning and learning, and corresponding languages for knowledge representation and organization. Products also include knowledge-based systems and tools that embody the methods of reasoning and learning.
From the viewpoint of cognitive science, DIL develops theories of visual and multi-modal reasoning in cognition, and their implications for design of interactive environments and tools.
