Viewer Perception of Superellipsoid-based Accelerometer Visualization Techniques

摘要

Viewer perceptions of superellipsoid-based glyphs representing trend analysis of tri-axial accelerometer data are studied in this paper. A trend analysis and its mapping to the superellipsoid parameters is proposed. Detailed results from a viewer survey about the usefulness of such glyphs are presented. Survey results indicate that approximately 60% of the respondents correctly identified the trend-related information and as much as an additional 27.2% acceptably identified some of the trend-related information. Overall, respondents indicated that the superellipsoid-based glyphs were helpful to understand accelerometer multi-plots.
