Adjustable XR Display Optics for Portrait and Landscape Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing XR devices have limited adaptability in their display arrangements, forcing a one-size-fits-all approach that restricts the orientation, extent, or position of the virtual content field of view, leading to suboptimal user experiences and constrained application design.
Innovation Solution
An adjustable display arrangement with an optical assembly that can dynamically switch between portrait and landscape modes by altering the optical path, using mechanisms like mechanical actuators or electro-optical components to adjust the virtual content field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed display arrangement is used in XR devices, then the device structure is simple and reliable, but the adaptability to different content orientations and user preferences is limited
Solution Approach 1:
The patent implements a dynamic display arrangement where the optical assembly can be adjusted between different orientations (e.g., portrait and landscape modes) to adapt to different content requirements and user preferences, transforming a static system into a flexible one
Solution Approach 2:
The optical assembly is designed to perform multiple functions by supporting different display orientations and configurations, allowing a single device to serve multiple purposes rather than requiring separate fixed arrangements for each content type
2Adaptability or versatility
If the virtual content field of view is fixed in orientation and extent, then the optical path is simple, but the ability to present diverse XR content without cropping is constrained
Solution Approach 1:
The optical path is made dynamic through adjustable optical elements that can reconfigure the light path to accommodate different content orientations and field of view requirements, enabling diverse content presentation without cropping
Solution Approach 2:
The system introduces additional degrees of freedom in the optical path configuration, allowing adjustment not only in orientation but also in the extent and position of the virtual content field of view, expanding presentation capabilities
3Ease of operation
If a one-size-fits-all display arrangement is used, then the device is easy to manufacture, but user experience is suboptimal due to inability to adapt to user preferences or application requirements
Solution Approach 1:
The display arrangement incorporates adjustable components that allow the system to adapt to different user preferences and application requirements, enhancing user experience while maintaining a relatively simple base manufacturing process
Solution Approach 2:
The system enables changes in display parameters such as orientation, field of view extent, and position through adjustable optical elements, allowing customization without fundamentally complicating the manufacturing process

AI summary
A head-wearable extended reality (XR) device includes a display arrangement. The display arrangement has a display to display virtual content, and also has one or more optical elements to direct the virtual content along an optical path to an eye of a user of the XR device. The virtual content is presented in a virtual content field of view. The display arrangement further includes an adjustment mechanism to alter the optical path so as to adjust the virtual content field of view between at least two display modes.
