Home Forums Legacy SDKs Fixation duration in Tobii Glasses Analyzer Reply To: Fixation duration

Sebastian Kraus

Hi Jenny,

I’m working with the Tobii Pro Glasses Analyzer export function with the I-VT fixation filter. After exporting the tsv I calculate the fixation- (and saccade) duration by grouping the eyeMovementType with eyeMovementTypeIndex and apply “timestampEnd – timestampStart”. I wondered because the mean fixation duration for our participants are between 90 and 160ms. Is this realistic?

Thank you for your feedback.
