Paper Abstract:
|
2D and 3D visualization has become a rapidly growing area of research during the past years. For a long time advanced
graphical techniques where mainly used within the scientific community, however, their potential benefits are now
increasingly recognized also for industrial applications. The visualization community is meanwhile following a theoryanchored
and evaluation based approach paving the way for the design of perceptually efficient visualizations.
In this paper we describe the development, evaluation and deployment of efficient visualizations to support process
operators in the paper and pulp process industry. We first identify and describe the data analysis task of the real working
situation at hand. Starting from existing theory in the field of visualization and vision research, we then describe the
process of designing perceptually motivated new visualizations for the specific task of the operators. The result is a new
deviation color scale that we apply to 2D color map and 3D height-field representations. We then describe an experiment
to formally evaluate the efficiency of these visualizations for the visual detection of thermal overheating of rotary kilns.
The results of this study showed that our new differential color scale lead to significantly reduced detection times when
compared with traditional color coding schemes. Also, when conventional color scales are used for the visualization of
absolute temperature levels, the inclusion of the 3D cues in the visualization for the visual encoding of the rate of change
contributes to faster detection of temperature increases. |
