BeGaze 2.3

4.3.2 Use Cases

BeGaze 2.3 can be used in a broad range of eye tracking data analyzing

contexts but there are typical use cases. To get familiar with the powerful

features of the program, it will be helpful to know some standard use

cases.

Advertising

This use case includes the evaluation of still images (e.g. print ads) or

video material (e.g. television commercials) which are presented to the

subjects using the SMI Experiment Center. With this use case, you

present the same visual stimuli to a larger group of subjects.

· Prerequisites:

– min. versions for still images: iView X 2.0.23 and Experiment

Center 2.0

– min. versions for videos: iView X 2.1.16 and Experiment Center 2.1

· Experiment design: Experiment Center is used to create and record

the experiment. The experiment includes various stimuli, such as

videos, still images, and text.

– Typical image presentation: Images (BMP, JPG, PNG) up to

1280x1024 pixels

– Typical video presentation: Videos (AVI) with 30 to 300 seconds in

length and a typical video size of 320x200, 640x480, or 720x576

pixels

· Experiment recording:

– Use a proper gaze tracking device (RED, Hi-Speed, or MRI/MEG).

– During the experiment, the data set is stored in the experiment's

results folder. The data set includes the presented stimuli as well as

the IDF files (gaze tracking data and user events), the subject

protocols, and the meta data (subject properties, experiment design).

· Typical evaluation: The analysis of this common use case is described

step-by-step in the Getting Started topic.
