TABLE 2.

Parameters for assessing the differences in the outputs of the benchmark (Raw60) and the adjusted fixation detection algorithms (Test filters).

Error component	Description
Overestimation of Total Fixation Duration (TFD)	The value by which the TFD(Test filter) exceeds the TFD(Raw60)
Underestimation of Total Fixation Duration (TFD)	The value by which the TFD(Raw60) exceeds the TFD(Test filter)
Error in Time to First Fixation (TTFF Error)	The absolute value of the difference between the TTFF(Raw60) and TTFF(Test filter)
Error in the ratio of participants viewing the Area of Interest (Percent Seen Error)	Mismatch between the Seen(Raw60) and Seen(Test filter)
