There are millions of people who annually experience motion sickness either because of vestibular stimulation or visually induced stimulation and the incidence is predicted to increase with increasing technology in new dynamic environments with advanced methods of locomotion and with the way we visualize information. For those experiencing the symptoms, the result is often disabling with associated drowsiness, lack of concentration and disorientation. It can result in incapacitating symptoms including nausea, emesis, unsteadiness, vertigo and loss of human performance. The impact of motion intolerance with resultant motion sickness is significant.

When symbology was visualized, nausea, oculomotor symptoms, and disorientation were less apparent. Objective SSQ scores were compared with and without visualization of the displayed symbology. The eye speed of nystagmus was also decreased from 26.3 degrees/second to 5.7degrees/second when using the visual display with vertex fixation. The duration of nystagmus, which persisted for 25.8seconds without the visual display, was decreased to 7.4seconds when using display and focusing on the vertex point. Similar finding were noted with Barany Chair stimulation. Eye speed of nystagmus was diminished from 13.6degrees/second, to 0.4degrees/second while using the visual display. With caloric stimulation testing, the duration of nystagmus was greater than 60seconds in the group without the visual display but decreased to 3.3seconds when using the displayed symbology and instructing the user to focus on the vertex point between the artificial horizon and centered vertical line. Results demonstrated the associated nystagmus was significantly reduced in velocity and duration. Users were tested with and without a visual display of specific symbology, while undergoing vestibular stimulation. This was followed by SSQ scoring to evaluate motion sickness symptoms. Assessment methods included an eye tracker, to measure velocity and duration of nystagmus, while patients underwent vestibular stimulation. The research objective was to determine if symptoms of motion sickness and associated nystagmus could be mitigated using an eye worn device which displayed an artificial horizon with a vertex point in the center for visual fixation, while experiencing vestibular stimulation. Motion sickness and complaints of dizziness caused by provocative vestibular stimulating environments have been a widespread problem, affecting a significant portion of the world’s population to varying degrees.
