| 1. | Some require fixation points to ensure they remain fixed in position.
|
| 2. | The effect is enhanced the further the stimulus is away from the fixation point.
|
| 3. | In spatial cueing tasks, subjects are instructed to fixate on a central fixation point.
|
| 4. | The line of sight is a virtual line connecting the fixation point in the outside world.
|
| 5. | With VRT therapy, the patient first focuses on a fixation point on a display screen.
|
| 6. | The alcohol slows down the movement and processing of the brain, therefore causing more fixation points.
|
| 7. | For example in the right eye a house is seen behind the fixation point through the window.
|
| 8. | The observer is looking at a point, the fixation point, on the interior of the sphere.
|
| 9. | Note that far disparities are smaller than near disparities for objects having the same distance from the fixation point.
|
| 10. | Geometrically the horopter is a circle passing through the nodal point of the two eyes and through the fixation point.
