When confronted with conflicting perceptual inputs on self-motion, users may experience motion and cybersickness symptoms, causing visual or other forms of physiological discomfort, such as troubled vision, headaches, or dizziness, or even more severe sickness effects such as nausea, vertigo, or vomiting. Several theories have been proposed to explain their occurrence, especially for motion sickness when displacing at sea, on a train, or in ground vehicles. With the advent of virtual environments and VR or AR systems, additional sickness effects have been observed due to the extended possibilities of virtual motion and visual conflicts or effects inducing impaired visual perception and recurring sickness effects (i.e., cybersickness), also called Virtual reality induced sickness effects (VRISE). Naturally, there are many methods for measuring and predicting motion and cybersickness, various new display system technologies for reducing visual inconsistency effects, and new navigational techniques for avoiding motion sickness. Today, the importance of these motion- and cybersickness-avoidance techniques is being reinforced with the progressive introduction of autonomous and connected vehicles, which might induce more frequent car sickness effects when the vehicle is in self-driving mode. Indeed, automobile motion sickness has been experienced by a large proportion of vehicle passengers, and as more autonomous vehicles are used in self-driving mode, more drivers will become passengers for extended durations. According to the identified sickness effects, various cybersickness avoidance techniques have been proposed. To avoid inconsistencies between visual eye accommodation and binocular cues, new visual display systems are proposed, often with several display screensScreens, corresponding to different virtual object distances. To deal with visuo-vestibular conflicts during virtual navigation, only rendered by the visualization of the perceived virtual world, various software solutions have been proposed. While many are well-known, they reduce natural navigation or the viewed scene; other more recent ones have not yet been industrially deployed. Finally, car sickness is progressively recognized as a major issue for the autonomous vehicle market by many OEMs, suppliers, and academic organizations, which are now increasingly developing new vehicle comfort and/or car sickness-avoidance methods.
