Sentence examples for fixation direction from inspiring English sources

It appears that continuous control of fixation direction available in VirtualEye should be especially useful in high-resolution perimetry [ 17].

It is not clear if continuous control of the fixation direction (checked before each stimulus) has some influence on the overall accuracy of the visual field determination.

The eye tracker permits strict monitoring of the subject gaze direction (fixation), which is potentially more accurate than standard perimetry where fixation is checked only occasionally during the test (typically, using the blind spot location as a control point).

Eye tracker enables real-time monitoring of gaze direction (fixation).

Direction bias scores (signifying initial orienting of attention) were calculated by computing the number of trials when the first fixation was directed onto the food image as a proportion of all trials in which the first fixation was made to either image (proportion scores >0.5 reflect an orienting bias toward food images; 0.5=no bias; <0.5 reflect an orienting bias toward non-food images).

Participants were adult patients with diagnosed retinitis pigmentosa whose binocular central visual field was constricted to less than 30° from fixation in all directions.

This interaction reflected consistent fixation shifts in the direction of the head turns, with nonsignificant or weaker fixation shifts in the direction of the ellipsoid rotations.

Measures were direction of initial fixation, last fixation prior to response, and dwell time.

To explore this possibility, Experiment 2 compared the standard peripheral indicator stimulus with a line at fixation pointing in the direction of the target.

We assumed that the centre of the IVF coincided with the centre of the image, since we had instructed the participants to keep their gaze, that is, their fixation, centred in the direction of the car's motion.

During viewing the wedge rotated around fixation in a clockwise direction at a rate of 16°/s, meaning that the wedge took 22.5 s to complete a single 360° rotation.
