Question Description

Write a graduate-level research papers providing an in-depth analysis relating to, dealing with, or having applied relevance to Video-Oculography benefits and drawbacks.Your papers should report on current research and should focus on research, knowledge, and information available from the primary professional literature. Papers will be unacceptable if primary sources from the behavioral, medical, or aerospace science literature are not referenced.

Use Primary Sources. Primary sources are reputable, peer-reviewed journals that describe research and results from original research such as Journal of Applied Psychology, Human Factors, International Journal of Aviation Psychology (IJAP), etc. Sources that people think are primary sources but are in fact not, are magazines such as Popular Mechanics, Scientific American, and encyclopedias are also not considered primary sources; these are secondary sources. Some secondary sources may be used, but not until you have enough primary sources (at least 5) to be able to scientifically back up the statement you make in your paper.

Your papers should be 5 to 7 pages in length to adequately address the topic.Current APA style is required. (no plagiarism)

Video-oculography refers to the method of recording the movement of the eye movement
using digital video cameras. Before the video-oculography method was discovered, it is the
electro-nystagmography method that was widely used for this process, which involved the use of
corneal retinal potential, the battery-like effect of the eye (Cerrolaza, 2008). The positive and
negative discharge of the corneal retinal potential is recorded during the up and down, and side
to side movement of the eye. However, the VOG technology utilizes infrared cameras for
measuring the position of the eye. It involves mounting small cameras in goggles and tracking
the pupil’s center in order to obtain the precise location of the eye.

Historical Perspective

Clinicians have been dependent on the electro-nystagmography or ENG, for so many
years, in the evaluation of central and peripheral vestibular functions. There is no doubt that the
technology, ENG, still remains to be the fundamental test for identifying and diagnosing the
unilateral vestibular dysfunction or UVDs (Kiderman, 2010). However, it has considerable
limitations in the recording and observation of torsional nystagmus. Another disadvantage that is
associated with ENG is that most of its tests require the patients to close their eyes, because it
may otherwise affect the eye. Therefore, for all this time before VOG emerged, clinicians have
relied upon graphic recordings that are unidimensional, and could only speculate about what
movements were made by the eyes beneath the closed eyelids (Van der Geest, 2002).

Over the past 10 years, microprocessor-based software algorithms and ENG have been
introduced, and have provided essential advances in the tests for vestibular function. Similarly,



head rotation tests, active and passive, for instance, the rotary chair and the vestibular
autorotation test or VAT, have significantly ena...
