Binocular Reader with Opaque Blinkers for Motion Sickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motion sickness occurs when the brain receives conflicting sensory information from the eyes and the body's movement, particularly when reading or watching videos in a moving vehicle, due to the discrepancy between perceived movement and actual movement, leading to nausea and discomfort.
Innovation Solution
A binocular mount device with a foldable and clip-on adapter for eyeglasses featuring partially opacified lenses with a small translucent 'view window' and blinkers to limit the visual field, reducing the perception of external movements and focusing attention on a fixed reading area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the visual field is kept wide to perceive the environment, then the user can see movements outside the vehicle, but the perception of external scrolls conflicts with reading a fixed point causing motion sickness
Solution Approach 1:
The visual field is segmented into multiple zones: a central translucent viewing area for reading fixed text, lateral opaque blinkers to block environmental movement, and a peripheral semi-transparent zone. This segmentation allows the reader to focus on a stable central area while blocking the harmful peripheral motion information that causes nausea.
Solution Approach 2:
Different parts of the spectacle have different optical properties: the central lens area is translucent to allow reading, the lateral blinkers are opaque to block motion perception, and the bridge area is translucent. This local differentiation of optical qualities enables simultaneous reading capability and motion blocking.
2Object-affected harmful factors
If the visual field is limited to a small area for reading, then the perception of external movement is reduced, but the user loses awareness of the environment
Solution Approach 1:
The blinkers are designed to extend beyond the minimum required to block lateral motion, creating an exaggerated lateral barrier. This excessive blocking action ensures complete elimination of motion perception while the central translucent area maintains reading capability, accepting complete environmental isolation as necessary to prevent motion sickness.
3Object-affected harmful factors
If the spectacle structure is made complex to effectively block lateral movement, then motion perception is eliminated, but the device complexity increases
Solution Approach 1:
The blinkers are merged with the spectacle frame structure, forming an integrated unit that combines the viewing function and the motion-blocking function in a single device. This merging eliminates the need for separate components and simplifies the overall structure while maintaining effective lateral motion blocking.
Solution Approach 2:
The spectacle device serves multiple functions simultaneously: it enables reading by providing a translucent central area, blocks lateral motion perception through opaque blinkers, and maintains a lightweight portable form factor. This multi-functionality reduces the need for additional separate devices.

AI summary
Device for reading in a car without nausea and headaches. The invention relates to a device that narrows the field of vision to the contours of the document's reading area, blocking out all external perception in a moving vehicle. It consists of a binocular frame with opaque lenses, each equipped with a restricted viewing window and two eyecups, allowing the user to read in a moving vehicle without nausea or headaches. The device according to the invention is particularly intended for passengers inside a moving vehicle.
