Head-Mounted Display Content Shifting to Protect Central Vision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted displays often fail to provide selective and interactive content presentation, particularly in situations where central vision obstruction could pose a safety risk, such as navigating crowded environments.
Innovation Solution
A method and apparatus that utilize contextual factors like viewer posture, gestures, and environmental conditions to selectively transform and output content to specific regions of the visual field, such as the peripheral or central vision, ensuring safety and optimal viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If content is output to the central visual field to take advantage of high visual acuity, then content viewing effectiveness is improved, but safety is worsened when navigating crowded environments
Solution Approach 1:
The system dynamically adjusts the output region for content based on the viewer's activity state. Sensors detect whether the viewer is stationary or moving (e.g., walking), and the system switches between central visual field output (when stationary) and peripheral visual field output (when moving). This dynamic adaptation resolves the contradiction by allowing content to be displayed in the optimal region depending on the current safety requirements.
Solution Approach 2:
The system changes the spatial parameter of content output by switching between different visual field regions (central vs. peripheral). When the viewer is stationary, content is output to the central visual field for optimal viewing. When the viewer begins moving, the system changes the output parameter to direct content to the peripheral visual field, thereby maintaining safety while preserving content delivery capability.
2Productivity
If content is continuously delivered to the display device, then information delivery is improved, but central vision obstruction increases in hazardous situations
Solution Approach 1:
The system dynamically controls content delivery by continuously monitoring the viewer's activity state through sensors. When motion is detected indicating a hazardous situation, the system dynamically adjusts the output region from central to peripheral visual field. This maintains continuous information delivery while adapting the spatial characteristics to avoid obstructing central vision when safety is concerned.
Solution Approach 2:
The system employs sensor feedback to detect the viewer's activity state (stationary vs. moving). This feedback loop enables the system to automatically adjust content output characteristics in real-time. When sensors detect movement indicating potential hazard, the feedback mechanism triggers a change in output region to peripheral visual field, thereby resolving the contradiction between continuous information delivery and avoidance of central vision obstruction.
Data Source
AI summary
A method, system, apparatus, and/or device for displaying a portion of data so as to not obstruct a portion of a central visual field. The method, system, apparatus, and/or device may include a display configured to display data and a processing device coupled to the display. The processing device may be configured to determine a position of an eye of a viewer with respect to the display, define a first region of the display substantially corresponding with a peripheral vision field of the eye, define a second region of the display substantially corresponding with a central visual field of the eye, send a first portion of the data to be displayed at the first region, and send a second portion of the data to be displayed at the second output region such that a portion of the central visual field is unobstructed by the second portion of the data.
