Information Synchronisation
The GazeTracker™ software gathers information from various different
sources:
This information is stored in a database.
Operating System
GazeTracker™ records and time stamps mouse movements, mouse clicks, and
keystrokes. GazeTracker™ compensates for changing content on the screen.
As users scroll web pages or videos change what it shown to the test subjects,
GazeTracker™ detects the changes and "corrects" the collected
data to associate where someone is looking to what is actually shown on the screen.
Additionally, GazeTracker™ tracks what web pages are displayed and what
hyperlinks are clicked. GazeTracker™ can automatically parse HTML files
and generate LookZones for images, hyperlinks, or text.
Lastly, GazeTracker™'s Software Analysis stores all of this data for the
particular applications the subjects interact with. For example, GazeTracker™ "knows" when
a test subject is interacting with Microsoft Word and is adjusting the
size of the Word window.
Questionnaires
Questionnaires allow researchers to define questions and allowable answers for
test subjects. These questionnaires can appear before and after data recording
takes place.
Eye-tracker
GazeTracker™ stores all gaze positions and pupil dilation measurements
that the eye-tracker reports. This data is time stamped and associated with the
particular application the test subjects interact with.
External Video Feed
GazeTracker™ can create AVI videos of external video feeds and synchronize
the videos created to the time stamps of the collected eye-tracking and operating
system data.
Database
A database is used to tie all of this information together. The database stores
the test setup (such as what images are viewed), test subject information, operating
system information, questionnaire data, and eye-tracking data. The database allows
information retrieval based on particular subject attributes.
