Abstract
We present a set of findings from our user evaluation of state-of-the-art TOI selection techniques. Tractography is a standard approach for visualizing the brain’s whitematter structure that is based on diffusion tensor imaging (DTI), and brain scientists need very efficient tools to select tracts-of-interest (TOI) for their research. We performed two evaluations aimed at better understanding of the tools: a subjective study of three standard TOI selection tools looking at the utility, usability and user satisfaction with the design features, and a user performance evaluation to measure the time performance and subjective reliability of two of the three standard TOI selection tools.
