Adjust the eye/camera

Instruct the patient to fixate on the center luminous dot.
Optimize pupil detection by focusing and adjusting the camera. The pupil should be centered. To
avoid partial occlusion by receding eyelids, participants can be told to open their eyes wide, the
eyelids can be torn gently under the rim of the goggles.
Align the camera by rotating it in its ball-and-socket joint such that the eye is finally centered in the
image. The camera can be rotated in three directions: yaw, pitch, and roll. At one time, however,
rotate the camera only in one of these three possible directions. After the eye is centered in one
direction, e.g., in the horizontal direction, choose the next rotation direction, e.g., the vertical direction.
A possible alignment sequence to center the eye is shown below.
Figure 4.2.2-1 Centering the pupil in the image with a sequence of three camera rotations. Immediately after the
goggles are placed on the patient, the eye can assume a position as in the upper left image. From this starting
position, the camera first needs to be rotated such that the pupil is centered horizontally.
