ImageMotion sickness is provoked by sensory conflict between visual and sensory-motor activities that involve the vestibular system through head movements. Although some individuals eventually adapt to situations that initially provoke such sickness, others do not. Motion sickness can cause pallor, drowsiness, salivation, sweating, nausea and, in more severe cases, vomiting. Eventually, motion sickness builds with time to the incapacitating level and impacted individuals cannot perform until the symptoms subside.

The US Army Research Lab developed and patented a system that includes a display device for compensating for motion sickness and a display controller for automatically adjusting the display to the motion sickness state of the person. Measurements of the speed and direction of the vehicle are delivered in real time by analyzing the images themselves, the speed of the vehicle, and pulling data from control signals for the vehicle or camera. Sensors can also be mounted on the display device, directly on the vehicle or in a wearable headset.
