What can help mitigate motion sickness by providing visual information?

Visual information plays a crucial role in mitigating motion sickness, particularly in aviation, where the disconnect between what the body feels and what the eyes perceive can lead to discomfort. Outside visual references, such as the horizon or landscape, help the brain reconcile sensory inputs by providing a stable frame of reference. When a pilot or passenger can see outside the aircraft, their visual system receives cues that correlate with the vestibular system's sense of balance and motion, effectively reducing the likelihood of motion sickness.

In contrast, internal cockpit readings focus primarily on instruments and displays inside the aircraft, which may not align with the pilot's physiological sensations and can exacerbate feelings of disorientation. Personal experience may inform a pilot about their unique responses to motion, but it does not actively provide the necessary visual cues to counteract motion sickness. Similarly, simulation tools are primarily for training and do not offer real-time external visual stimuli that help ground the pilot's perception during actual flight.
