Peripheral Light Track Around a Central Display for Wearable Visual Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mountable devices face challenges in managing simultaneous display of primary and supplemental content without impacting responsiveness, battery life, and user experience, particularly when supplemental content is overlaid on the central display.
Innovation Solution
The device incorporates a central display with a surrounding light track that provides supplemental content independently, using light emitters with adjustable controls to create a single continuous image without modifying the central display output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If supplemental content is overlaid on the central display, then information delivery is enhanced, but computational load and power consumption increase
Solution Approach 1:
The display system is segmented into two independent output channels: a central display for primary content and a peripheral light track for supplemental content. This segmentation allows each component to operate independently with optimized computational requirements, reducing the overall processing load compared to rendering all content on a single high-resolution display.
Solution Approach 2:
The patent transitions from a two-dimensional central display to a three-dimensional arrangement by adding a peripheral light track that surrounds the display. This spatial dimensionality change allows supplemental information to be delivered without competing for the same computational resources or visual real estate on the central display plane.
2Loss of information
If supplemental content is overlaid on the central display, then information delivery is enhanced, but user experience and responsiveness deteriorate
Solution Approach 1:
By segmenting information delivery between central display and peripheral light track, the system prevents information overload on a single interface. Users can process primary and supplemental information through separate visual channels, improving comprehension and responsiveness without experience degradation.
3Device complexity
If a single display is used for all content, then device complexity is reduced, but information delivery and user experience worsen
Solution Approach 1:
The peripheral light track serves multiple functions: delivering supplemental information, providing visual feedback, and enhancing situational awareness. This multi-functionality allows the system to achieve enhanced information delivery without proportionally increasing complexity, as a single peripheral component accomplishes multiple objectives.

Function Achieved in This Case
This approach enhances user experience by maintaining central display functionality while reducing computational load and power consumption, allowing seamless integration of supplemental information without interrupting the primary display.
Implementation Method 1
light emitters surrounding the display, wherein the optical assembly is operable to produce an image that includes both an output of the display and an output of the light emitters within a field of view

AI summary
A wearable electronic device can include optical assemblies for providing visual output to a user. The optical assemblies can include a central display as well as a light track that surrounds at least a portion of the central display. Primary information and images can be provided at the central display to be received at a center region of a user's vision. Supplemental content and/or information can be provided by operation of the light track, which can be operated with relatively simple controls. The supplemental content and/or information can be received at a peripheral region of the user's vision. Accordingly, the inner and outer images produced by the separate mechanisms of the optical assembly can provide a single continuous image for observation by the user.
