Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with displays struggle to effectively manage different scaling and weighting of image regions based on predetermined areas of interest, particularly in head-mounted devices with inward and outward-facing displays, leading to suboptimal user experience and communication with the environment.
Innovation Solution
The device incorporates a housing with inward and outward-facing displays, where the outward-facing display adjusts its scaling and weighting based on predetermined areas of interest in the image, using cameras and control circuitry to generate and display images with non-uniform scaling and weighting, enhancing user interaction and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If uniform scaling is applied to the entire image, then the display maintains simple processing and consistent proportions, but important details in specific regions are lost and user experience is suboptimal
Solution Approach 1:
The patent divides the image into multiple regions of interest (ROIs) based on predetermined attributes such as facial features, objects, or areas requiring enhanced display. Each region is then scaled independently using different scaling factors, allowing high-precision display of important details while maintaining overall image coherence. This segmentation approach resolves the contradiction by enabling region-specific precision without requiring complete redesign of the entire display system.
Solution Approach 2:
The patent applies different scaling factors to different regions of the image based on their importance and predetermined attributes. Critical regions receive higher scaling factors for enhanced detail, while less important regions use lower scaling factors. This local quality differentiation allows the system to achieve high manufacturing precision where needed without uniformly increasing complexity across the entire image processing pipeline.
2Ease of operation
If non-uniform scaling is applied to enhance specific regions, then user experience and communication effectiveness improve, but the device complexity and processing requirements increase
Solution Approach 1:
The patent pre-defines multiple scaling factors and their corresponding regions based on predetermined attributes before actual display operation. The system stores these scaling configurations in advance, allowing rapid selection and application during operation without complex real-time calculations. This preliminary action reduces the computational burden and control complexity during actual use while maintaining high user interaction quality.
Solution Approach 2:
The patent implements dynamic switching between different scaling configurations based on detected attributes or user input. The system can adaptively select appropriate scaling factors and regions in real-time, providing flexible and responsive user experience. This dynamic approach allows the device to handle various scenarios efficiently without requiring overly complex fixed architectures, resolving the contradiction between ease of operation and device complexity.
3Illumination intensity
If scaling factors are adjusted based on ambient lighting conditions, then visibility and communication effectiveness improve, but the system adaptability requirements increase
Solution Approach 1:
The patent incorporates sensors that detect ambient lighting conditions and provide feedback to the display control system. Based on this feedback, the system automatically adjusts scaling factors and display parameters to optimize visibility in different environmental conditions. This feedback mechanism enables the system to adapt to lighting changes without requiring complex manual intervention or pre-programming for every possible scenario, effectively managing the adaptability requirement while improving illumination intensity.

AI summary
An electronic device may have an inner display that displays images for a user and an outer display that informs nearby people of the status of the user and inner display. For example, the outer display may display an image of a face and/or an abstract layer depending on an operating mode of the inner display. The outer display may be a three-dimensional display that displays a three-dimensional image based on a two-dimensional image. The two-dimensional image may be scaled based on predetermined attributes of content in the two-dimensional image with predetermined, non-uniform scaling and/or weighted with predetermined, non-uniform weighting based on one or more known/predetermined areas of interest. The predetermined attributes may be located using heuristics, tracking, and/or machine learning. Areas of interest with high complexity may be scaled to be larger than or weighted to be more defined than areas of lower complexity.
