Recording frequency

During the study, our eyetracking software records the locations and timestamps of each gaze point. However, this does not inform us about how fast the software is able to process the incoming gaze data for each participant. Recording frequency shows this missing information. It is calculated as the reciprocal of the average session duration (per stimulus). Average recording frequency is the mean of the recording frequency of all sessions (in a study). The measuring unit is in Hz. Larger average recording frequency numbers indicate more data recorded for the given session (or averaged over a study). The minimum frequency value is 0 Hz and the maximum value is 100Hz. If the average of the frequency is lower than 5Hz, we suggest our users redo the study.
