| Abstract |
| In order to perform daily maintenance and repair tasks in complex
electrical and mechanical systems, technicians commonly utilize a
large number of diagrams and documents detailing system properties
in both electronic and print formats. In electronic document
views, users typically are only provided with traditional pan and
zoom features; however, recent advances in information visualization
and illustrative rendering styles should allow users to analyze
documents in a more timely and accurate fashion. In this paper,
we evaluate the effectiveness of rendering techniques focusing on
methods of document/diagram highlighting, distortion, and navigation
while preserving contextual information between related diagrams.
We utilize our previously developed interactive visualization
system (SDViz) for technical diagrams for a series of quantitative
studies and an in-field evaluation of the system in terms of
usability and usefulness. In the quantitative studies, subjects perform
small tasks that are similar to actual maintenance work while
using tools provided by our system. First, the effects of highlighting
within a diagram and between multiple diagrams are evaluated.
Second, we analyze the value of preserving highlighting as well as
spatial information when switching between related diagrams, and
then we present the effectiveness of distortion within a diagram. Finally,
we discuss a field study of the system and report the results
of our findings. |
