Video Recordings

During an intensive play situation it is not possible to simultaneously observe the responses of a child. Another person may function as the observer or the play situation is recorded on video for later analysis by the vision team, early intervention team and by the child's neurologist. When testing an infant or a child who does not move a recording is possible by placing the video camera on a tripod. If the camera can be connected to a TV behind the child the tester can check that the child remains positioned within the picture area, does not lean outside the picture.

If the child has good enough head control and fixation so that calibration of the test is accurate, eye movements during reading can be recorded with eye trackers. Children, who have poor head control and great problems with eye movements and crowding, are best examined by the video recording of eye movements using a mirror and transparent texts.

Figure 19. Video recording via a large mirror allows recording of eye movements, head, hand, and body control during reading. This expensive instrument has been useful in examination of reading difficulties of children with irregular fixation and/or saccades and/or scanning.
