Augmented Display for Motion Sickness Alleviation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passengers in vehicles often experience motion sickness due to a lack of a forward-facing view, which can be exacerbated by interacting with display devices while in motion, as their senses perceive vehicle motion without a corresponding external view.
Innovation Solution
A system using a video capture device to provide an augmented display on a vehicle's display device, allowing passengers to select between a passive video mode for viewing external video data and an active video mode for interactive games and virtual object creation, thereby alleviating motion sickness by providing a visual reference of the vehicle's path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If passengers interact with display devices while the vehicle is in motion, then entertainment and productivity are improved, but motion sickness is worsened
Solution Approach 1:
The patent introduces an intermediary system that captures the driver's view through a camera and displays it on the passenger's device. This intermediary visual feed acts as a mediator between the passenger and the external environment, providing motion cues without requiring the passenger to look outside, thus preventing motion sickness while maintaining entertainment capability
Solution Approach 2:
The system creates a visual copy of the driver's perspective and transmits it to the passenger's display device. This copied view serves as a synthetic external reference that mimics the actual external environment, providing the necessary motion visual cues to prevent sensory conflict and motion sickness
2Quantity of substance
If passengers are positioned without a forward-facing view (e.g., rear seats), then vehicle capacity and safety are improved, but motion sickness is worsened
Solution Approach 1:
The camera-based system serves as an intermediary that captures the forward view from the driver's position and transmits it to passengers in positions that would otherwise lack external visual access. This allows rear-seat and other restricted-position passengers to access external motion cues without changing their physical position in the vehicle
Solution Approach 2:
The patent transports the external visual information from the driver's spatial dimension to the passenger's device display dimension. By moving the view capture point (driver's forward view) and delivering it through a different dimension (digital display), passengers in any vehicle position gain access to external motion references
3Productivity
If passengers focus on stationary display content while the vehicle is in motion, then entertainment is improved, but sensory conflict is worsened
Solution Approach 1:
The system merges stationary entertainment content with dynamic external video feed, allowing both types of content to be displayed simultaneously. The external video provides motion reference while entertainment content remains available, combining the benefits of both stationary and dynamic visual stimuli without causing sensory conflict
Solution Approach 2:
The display system transitions from purely static entertainment content to dynamic content that includes real-time external video feeds. This dynamic element adapts to the vehicle's motion, providing continuously updating visual references that match the passenger's sensory experience of movement

AI summary
Systems, methods, and computer-readable media are disclosed for using a video capture device to alleviate motion sickness via an augmented display for a passenger. One method includes receiving, from a video capture device of a vehicle, video data of a view outside of the vehicle while the vehicle is in motion; displaying, on a display device for a passenger of the vehicle, a request for a mode of display of the video data, the mode of displaying including a passive video mode and an active video mode; receiving a selection of the mode of display; displaying a request for a video display type when the passive video mode is selected; and displaying the video data including a menu, the menu including a plurality of selectable icons to interact with the video data when the active video mode is selected.
