Tobii Eye Tracker and ClearView analysis software
© Tobii Technology AB, 2006
Record
When the stimuli and subjects have been prepared recordings can be made. In
most cases a recording procedure will consist of four steps:
•
Verifying tracking ability and the subject’s position in front of the screen using
the track status meter.
•
Performing (or selecting) a calibration.
•
Verifying calibration quality using the real-time gaze display.
•
Performing the stimulus presentation and doing the actual recording.
To access the recording tools click on the Record button on the toolbar or in the
lower right corner of the ClearView main window.
For more details, see the chapter Recording Tools below.
Analyze
Once recording is finished the data collected can be analyzed in the analysis
section of ClearView. There are several different tools available in ClearView for
data visualization and analysis. Depending on the type of study, the work-flow
during analysis may vary quite a bit. For many studies though the following steps
would be performed
•
Using the different visualization tools (gaze replay, gaze plot and hotspot plot)
to get a qualitative view of the data and identify behavior of interest.
•
Defining areas-of-interest to facilitate meaningful data quantification.
•
Making raw text exports or use DirectExcel templates for quantitative analysis
and conclusions.
To access the analysis tools click on the Analyze button on the toolbar or in the
lower right corner of the ClearView main window.
For more details, see the chapter on Analysis and export tools below.
The ClearView Sample package
On the ClearView installation CD there is a folder with Sample files including a
Sample package. These folders contain a number of useful files including pictures,
movies, analysis tools and templates for easy creation of different stimuli. Place the
Sample package in the ClearView Stimuli folder defined in Global Settings. The
default location of this folder is C:\Program Files\Tobii\ClearView\Stimuli.
The Sample package includes the following folders:
•
AVI Samples – AVI movies that can be used to test the AVI stimuli
•
Direct Excel Templates – Analysis templates used with the Direct Excel
export from ClearView. See also the section DirectExcel export in this manual.
•
Generators – Excel templates that can be used to create script files for Moving
Bitmap and Slide show stimuli
•
Image Samples – A collection of pictures in different formats that can be used
to test the Image and Slide show stimuli. In this folder there are also specially
designed accuracy test images to test calibration quality with the Real time gaze
view tool (See the section Recording tools below).
