Peripheral Light Elements for Head-Mounted Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted displays (HMDs) that are not see-through types cause users to experience motion sickness due to occluded peripheral vision, leading to discomfort and reduced usability during extended use.
Innovation Solution
The implementation of peripheral light elements that dynamically match the colors surrounding the display area with the image on the HMD, enhancing the user's field of view and reducing the 'tunnel effect' by coordinating the peripheral area with the central image, using light emitting diodes or other displays, and processing algorithms to customize the viewing experience based on individual user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a head-mounted display blocks the user's peripheral vision to display images, then the image display function is improved, but the user experiences motion sickness and discomfort
Solution Approach 1:
The patent applies color changes by dynamically adjusting the illumination color temperature of peripheral light elements to match the color temperature of the displayed image content. This creates a coordinated visual environment that reduces the contrast between the display area and peripheral areas, thereby mitigating motion sickness while maintaining image display functionality.
Solution Approach 2:
The patent implements local quality by selectively illuminating different peripheral regions with light elements that have different color temperatures corresponding to the local color temperature of the image content in those regions. This localized coordination approach addresses motion sickness in specific peripheral areas without affecting the overall image display quality.
2Device complexity
If the display area is limited in size, then the device complexity is reduced, but the field of view appears restricted creating a tunnel effect
Solution Approach 1:
The patent applies dimensionality change by extending the visual experience from the two-dimensional display area into the three-dimensional peripheral space through strategically positioned light elements. These elements project illumination into the peripheral field of view, creating a sense of expanded spatial presence without increasing the physical display area or device complexity.
Solution Approach 2:
The patent uses peripheral light elements as intermediaries between the display system and the user's peripheral vision. These light elements mediate the transition from the confined display area to the broader peripheral field of view, creating a seamless visual experience that eliminates the tunnel effect while maintaining a compact display structure.

Function Achieved in This Case
This solution increases viewing comfort, reduces the likelihood of motion sickness, provides a larger virtual field of view, and enhances the overall image brightness, resulting in an improved immersive experience for users.
Implementation Method 1
a first peripheral light element positioned to emit light of one or more colors in close proximity to the periphery of the first display
Data Source
AI summary
Methods and apparatus, including computer program products, implementing and using techniques for projecting a source image in a head-mounted display apparatus for a user. A first display projects an image viewable by a first eye of the user. A first peripheral light element is positioned to emit light of one or more colors in close proximity to the periphery of the first display. A receives data representing a source image, processes the data representing the source image to generate a first image for the first display and to generate a first set of peripheral conditioning signals for the first peripheral light element, directs the first image to the first display, and directs the first set of peripheral conditioning signals to the first peripheral light element, As a result, an enhanced viewing experience is created for the user.
