Sentence examples for minimum fixation threshold from inspiring English sources

In the event that a data set is very noisy, the minimum fixation threshold should be set higher.

Dispersal-based algorithms use a minimum fixation duration threshold (e.g., 50 ms) and the positional information (dispersion) of the eye-tracking data in order to decide whether consecutive points belong to the same fixation in which case, they are grouped together.

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

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.

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).

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.

(2) For the fixation period, we also calculated the disconjugate drift in vergence [6], that is, the change in vergence between the beginning of the fixation period and the minimum fixation disparity (M-E in Figure 1b).

Delete them Post hoc validation: Minimum fixation duration 6.1.

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°).

(6) The minimum fixation for the first stimulus prior to fixation was set at.70 of the total possible gaze samples available during the presentation window (including interpolated data).

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].
