By using principles of the creative design process, a series of low-level prototypes and user studies were created to inform the design of an information visualization technique that deals with the problem of visually representing information quality. Understanding and clearly representing information quality is an important step in overcoming the problems of "information overload", a term used to describe the problem of having stronger data collection than data processing techniques. The hypothesis was that illustrative rendering techniques would be an intuitive and effective means for the display of information quality in multidimensional datasets. The user studies showed that to a general population exposed to familiar imagery, illustratively rendered areas of that imagery do intuitively appear to be of a lower quality than realistically rendered areas. When given that low quality is represented by illustrative rendering techniques, users can distinguish various levels of quality within a visualization, isolate specific areas of low quality within a larger visualization, and interpret locations of low quality regions within a three-dimensional visualization.
