Near-Eye Display Reading Mode With Tilt-Based View Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing near-to-eye display devices struggle to provide displayed images in the most natural way possible while maintaining automated selection of a region of interest, particularly for individuals with significant central vision loss or legal blindness.
Innovation Solution
A near-to-eye display device with a camera, displays, and a controller that automatically switches between display modes based on user activities, such as detecting a downward tilt or image analysis, to select appropriate regions of interest for viewing, including reading, non-reading, TV/movie, and sport modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display shows a smaller field of view to enhance natural vision for reading, then reading comfort is improved, but the ability to see surrounding environment is reduced
Solution Approach 1:
The display dynamically adjusts its field of view based on detected user activity. When reading mode is detected through downward tilt sensing and image analysis, the display narrows to show only the lower portion of images for optimal reading comfort. When non-reading activities are detected, the display widens to show a broader field of view, thus adapting the balance between reading comfort and environmental awareness.
Solution Approach 2:
The system changes the display parameter (field of view) based on detected tilt angle and image content. By detecting downward tilt beyond a threshold and analyzing images for reading material, the controller adjusts the displayed region from a broader view to a narrowed reading-optimized view, and vice versa.
2Ease of operation
If the display automatically selects regions of interest based on image analysis, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system performs self-service by automatically detecting user activity through image analysis and tilt sensing, then autonomously selecting appropriate display modes without user intervention. The controller analyzes images to detect reading material and determines activity state, automatically switching display regions accordingly.
Solution Approach 2:
The system uses feedback from image analysis and tilt sensors to automatically adjust display settings. The controller continuously monitors image content and device orientation, using this feedback to determine when to switch between reading mode and other activities, creating a closed-loop adaptive system.
3Adaptability or versatility
If the display provides multiple display modes for different activities, then adaptability is improved, but device complexity increases
Solution Approach 1:
The display system is designed with multi-functionality to support multiple activities through a single device. By implementing multiple display modes (reading mode, non-reading mode, and other activity-specific modes) that can be automatically activated based on detected user behavior, the system provides universal adaptability across different usage scenarios without requiring separate devices.

AI summary
A near-to-eye display device is provided that includes a camera for capturing images in a first field of view; at least one display positioned near to an eye of a person wearing the device for displaying images captured by the camera in a second field of view, wherein the second field of view is smaller than the first field of view; and a controller for selecting a portion of the images from the camera to display on the display. The controller being configured to automatically enter a reading mode upon detecting one of a downward tilt of the device and reading material within the images. In a reading mode, the controller selects a lower portion of the images to display on the display. When not in a non-reading mode, the controller selects a higher portion of the images to display on the at least one display.
