4.5 Data Collection and Eye Tracking Metrics J
Areas of Interest (AOI’s) were designated for the creole stimuli and used to determine three measurements
metrics of eye movement: Time to First Fixation (TTFF), Total Fixation Duration (TFD), and Fixation Count
(FC). The time in seconds from when a product first enters a participant’s field of view until they fixate on it is
defined as the TTFF. The lower the number, the better the package performed in this instance. TFD, is the time,
in seconds, spent on average by participants fixating on this item. The higher the number, the better the package
performed. FC is the total number of times a participant’s scan of the planogram crossed into a particular area of
interest.
A survey created through SurveyMonkey.com including questions on the product and demographic information
was created in conjunction with the private label company. Tobii Studio was used to collect raw eye tracking
data and run statistical analysis. Using SAS® Studio, an Analysis of Variance (ANOVA) was used to determine
if the measured data was significantly different (5%) for the three types of canned creole. If indicated that there
was significant difference, a LSD multiple comparison test would be used to determine what brands differed
