Designers use different symbols and configurations in their drawings to explore alternatives and to communicate with each other. For example, when thinking about spatial arrangements, they draw bubble diagrams; when thinking about natural lighting, they draw a sun symbol and light rays. If this is true, therefore one can infer design intentions from the drawing and can use this inference to program a computer to understand our drawings. This dissertation reports the findings from empirical studies of drawings and explores the possibility of using the computer to automatically infer designer's concerns directly from the drawings that are made.

520 # $a Designers use different symbols and configurations in their drawings to explore alternatives and to communicate with each other. For example, when thinking about spatial arrangements, they draw bubble diagrams; when thinking about natural lighting, they draw a sun symbol and light rays. If this is true, therefore one can infer design intentions from the drawing and can use this inference to program a computer to understand our drawings. This dissertation reports the findings from empirical studies of drawings and explores the possibility of using the computer to automatically infer designer's concerns directly from the drawings that are made.
520 # $a Recognizing that it is possible to associate symbols and spatial arrangements in the drawing with the designer's intention, or task context, then the second goal is to find out whether can one program a computer to recognize these drawing conventions. With inferred intention and context, a program can activate appropriate design tools automatically. For example, concerns about visual analysis can activate a visual simulation program and number calculations can activate a calculator. The Right-Tool-Right-Time prototype program demonstrates how a freehand sketching system that can infer intention would support the automated activation of different design tools based on designers' drawing acts.
520 # $a The main goal is to find out what is in designers' drawings that a computer program should recognize and support. Experiments have been conducted to study the relation between drawing conventions and their associated tasks. It was found from the experiments that designers used symbols and configurations to put themselves in mind of design concerns. When thinking about allocating objects or spaces with a required dimension, designers wrote down numbers beside the drawing to reason about size and calculate dimensions. When thinking about visual analysis, designers drew sight lines from a view point on a floor plan.
520 # $a This dissertation covers three parts: (1) a literature review of design studies, cognitive studies of drawing and computational sketch systems, and a set of pilot projects; (2) empirical studies of diagraming design intentions and a design drawing experiment; and (3) the implementation of a prototype system called Right-Tool-Right-Time.
