ANALYSIS WITH GAZETRACKER™

Combining faceLAB® with GazeTracker™ provides a sophisticated method of screen-based user behaviour analysis. This snapshot shows a user's viewing pattern of a website.

faceLAB® v4's native support for Eye Response Technologies' GazeTracker™ simplifies the analysis process with a flexible and easy-to-use set of analysis tools.

The benefits of faceLAB® v4's highly accurate eye tracking and unhindered subject movement can quickly be realised when combined with GazeTracker™ analysis software. Providing one location for presenting, gathering and analysing screen-based stimulus, GazeTracker™ simplifies the delivery and analysis process in conducting a behavioural experiment.

Analysis of statistical data is more simple and can be done in real time with stimulus, providing a rapid way to draw real outcomes. The overall time and cost required to setup and conduct an experiment is also greatly reduced through faceLAB's native integration, allowing you to concentrate on the outcomes of your experiement rather than the technicalities.

Still Image Analysis

GazeTracker™'s Still Image Analysis displays a sequence of static images on a computer. The next image appears after a predefined length of time or when a specific keystroke or mouse click is made. GazeTracker™ gathers information, such as eye position and pupil dilation, as recording takes place.

LookZones

LookZones are easily definable regions of interest that researchers can specify in any of GazeTracker™'s analysis modes (still images, videos, or software applications).

LookZones generate statistics based upon actions occurring inside of the zone. Some of these statistics include number of times the region was observed, number of mouse clicks in the region, and total time spent looking in the region. LookZones may be any size or shape. An unlimited number of them may be set up in any analysis mode. LookZones can also be dynamic, automatically changing size and position for changing screen content in response to scrolling, videos, or animation.

Web Content Analysis

GazeTracker™'s webpage analysis mode includes all of the features of Application Analysis plus some capabilities unique to analyzing web pages. GazeTracker™'s ability to analyze dynamic content allows the software to seamlessly provide the information that researchers need to effectively analyze web sites. GazeTracker™ parses the HTML and knows the layout of the page, automatically establishing LookZones on images and hyperlinks. The pages visited by the test subjects are also automatically stored.

Graphing

GazeTracker™'s primary methods of graphing data include:

• Pupil Dilation Graphs: Pupil graphs show the captured fluctuations in pupil dilation over time.
• Automated Excel™ Graphs: GazeTracker™ has the ability to automatically generate a variety of graphs in Microsoft Excel™.
• 3D Graphing: 3D graphing offers a topographical map of the eye-tracking data, or it can combine a bar chart with a 3D view of the stimulus. A topographical map creates mountains and valleys directly on the stimulus based on where subjects looked. 3D bar graphing raises portions of the stimulus where LookZones are located. The height of the LookZones indicates the total time the zone was observed. Pictured above is a 3D bar analysis of a website.
• LookZone Order Graph: A LookZone Order graph depicts a timeline showing the order and duration in which a test subject observed each region of interest.
