Uncertainty Visualization

Description of Research

The level of data uncertainty can be a crucial component in making an informed decision. If the goal of visualization is to provide insight into data, then the certainty of that data should also be presented. From MRIs used by medical professionals to wind speeds used by fire-fighters, misconstrued confidence or simply a lack of consideration of data uncertainty can have life threatening implications. Nevertheless, the presentation of information certainty (or the lack thereof) can be difficult when the mere problem of effectively presenting absolute data alone necessitates a complex solution. Whether ignoring uncertainty or presenting it while sacrificing another data variable, the consequences of incomplete information may be unacceptable for the intended viewer. Though the field of uncertainty visualization has made great strides recently, more techniques are needed for scenarios that reach the limitations of current visualization methods.
