We
have created a number of visualizations to aid in our interpretation
and analysis of the data, inspired by
David S. Wooding's article, 'Eye Movements of Large Populations
II: Deriving Regions of Interest, Coverage, and Similarity Using
Fixation Maps.' Below are several examples of the types of
visualizations we find most beneficial.
Fixation
Height Maps
Using
3-dimensional contours, these maps depict aggregate fixation data.

| Shadow
Intensity Maps
These maps also depict the intensity of eye gaze to particular
regions of a web page; however, the degree of attention to particular
regions is emphasized by relative lightness. |

Visualization
Application
We are developing an application to employ these visualizations
as a basis for contextual exploration of other metrics available
from the eye tracker. The application also provides considerable
support for scanpath analysis and locating regions of interest.
In the absence of a standard format for eye-tracking data, we
hope to present a generalized file format and post the application
for download. |
