Sentence examples for minimum fixation duration from inspiring English sources

Fixations were defined temporally and spatially using a pre-set minimum fixation duration of 80 milliseconds (ms) and a maximum dispersion value of 100 pixels.

Delete them Post hoc validation: Minimum fixation duration 6.1.

Delete them Find all fixations with an RMS over the threshold Delete them Post hoc validation: Minimum fixation duration 6.1.

Visual fixations were detected using a dispersion-based algorithm with a minimum fixation duration of 100 ms and a maximum dispersion of two degrees [ 17].

Thus, for example, they identify a period of raw gaze data as belonging to a fixation by starting with a window size of the minimum fixation duration (e.g., 80 ms) and expanding it until the average displacement of the eyes during the window is greater than the displacement threshold (e.g., 0.5°).

Gitelman reports that the algorithm is sensitive to the choice of thresholds for defining a fixation, including the maximum horizontal and vertical eye movements, and the minimum fixation duration (Karsh & Breitenbach, 1983), and the user has to define these thresholds based on the task, stimuli and equipment.

Thus, the histograms for the fixation durations had to be bounded between the minimum and maximum fixation duration value for the block of trials, and then evenly divided into N/10 bins, N being the total number of fixations throughout the block of 111 trials.

In particular, the post hoc algorithms (1) merge adjacent fixations that are close in space and time, (2) remove all the fixations whose RMS is over a given threshold, and (3) delete all the fixations with shorter duration than the minimum fixation (in this order).

Participant 3 is intermediate, with a mean of 354 ms, a mode of 100 ms, and a median of 279 ms. For 2 of the 3 participants, the mode is 100 ms, which is the shortest possible fixation duration (due to the minimum temporal duration criterion identified above, all fixations shorter than this are excluded).

Fixation duration (seconds): duration of each individual fixation in an AOI.

Specific parameters of interest were the fixation count (number of fixations inside the AOI), first fixation duration (duration of the first fixation to hit the AOI) and total fixation time (sum of the fixation durations inside the AOI).
