Motion sickness most often results from a sensory conflict between inputs from the visual and vestibular systems. Substantial proportion of passengers, who attempt to perform reading and other activities, do experience motion sickness. For example, about 50% of adults get motion sick, at least occasionally, when reading a book in a moving vehicle. It is important to note that motion sickness is expected to be of even greater concern with autonomous, self-driving vehicles, because all persons aboard will now be passengers. The three main factors contributing to motion sickness (conflict between vestibular and visual inputs, inability to anticipate the direction of motion, and lack of control over the direction of motion) are elevated in self-driving vehicles. Therefore, new technologies that can provide universal solutions to motion sickness in vehicles have important potential to contribute to autonomous driving vehicles market which is expected to have 3 million automated vehicles by 2025.
Device and Task Independent Universal Countermeasure for Motion Sickness in Vehicles and Autonomous Driving
A motion sickness prevention technology that consists of an array of lights or similar visual stimuli presented in the viewer’s peripheral field of view is proposed. Via these visual stimuli, presenting apparent motion (such as forward velocity, yaw rate, and/or pitch rate of the vehicle) in a viewer’s peripheral field of view allows the person to look away from the outside scene, such as would occur when working on a laptop, reading, playing video games or watching movies, and yet still be able to perceive the motion of the vehicle while performing such tasks.
The current proposed technology can be installed in a variety of wearable items (mounted on goggles, glasses, hat brims, etc.), or can be vehicle mounted (in the vehicle interior in such locations as the doors, roofline, headliner, pillars, floor, console, dashboard, etc.). In addition to automotive applications, these embodiments may also be applied to other vehicle types including aircraft, ships, boats, trains, and other transportation modes where users are susceptible to motion sickness. Contrary to existing motion sickness countermeasures presented as simulated motion around a video frame (such as with a phone or laptop screen) which are tied to each specific device, the proposed technology is both device independent and task independent.
- Autonomous vehicles
- Motion sickness prevention
- Helps reduce the frequency and severity of motion sickness
- Both device independent and task independent
- Can be installed in a variety of wearable items
- Requires only a small portion of the user’s peripheral field of view to be blocked
