HumMod explorer: a multi-scale time-varying human modeling navigator

HumMod [Hester et al. 2011] models interactions between the cardiovascular, respiratory, renal, neural, endocrine, skeletal muscle, and metabolic physiologies. One of the difficulties which must be overcome with HumMod is the fact that the number of parameters is prohibitive in developing a clear and comprehensive view of the interactions between parameters. Currently the HumMod model contains more than 5000 variables. Therefore, good visualization techniques are needed to discern non-obvious relationships between variables. We present HumMod Navigator, a multiple-scale physiology data browser for exploring casual relationships of time-varying human modeling data. The visualization makes use of a circular layout and hierarchical relations to effectively visualize interactions between model parameters in an attempt to obtain both a local and comprehensive view of the physiological modeling environment.
