Portable Display Adaptation via Distance Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies for portable devices, such as HMDs, struggle to effectively display information relevant to a work object while the user is performing tasks, as they primarily focus on location-based content changes rather than adapting to the proximity and context of the work object.
Innovation Solution
A display system that includes a portable device with a distance detection section and a display control section, which adjusts the display mode of object-related information based on the detected distance from the work object, ensuring that the information is presented in a suitable format that minimizes visual disturbance and prioritizes relevant content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If location-based content switching is used in portable display devices, then the device can display different content based on GPS location, but it cannot adaptively display information relevant to the work object based on the user's proximity and interaction context
Solution Approach 1:
The display device dynamically adjusts its display mode based on real-time detection of distance to the work object. The display control section changes between first display mode (when distance exceeds threshold) and second display mode (when distance is within threshold), making the display adaptive to the user's proximity and interaction context rather than relying solely on static location-based content switching
Solution Approach 2:
The distance detection section continuously monitors the distance between the user and the work object, providing feedback to the display control section. This feedback loop enables the system to automatically adjust the display mode based on the detected distance, ensuring that the most relevant information is displayed at the appropriate time according to the user's proximity to the work object
2Loss of information
If the display device shows detailed object-related information, then the worker can access relevant content, but it causes visual disturbance and clutter that hinders work performance
Solution Approach 1:
The display device applies different display qualities and information densities to different spatial contexts. When the user is far from the work object, detailed information is displayed to provide comprehensive context. When the user is close to the work object, the display mode changes to show only essential information or simplified views, reducing visual clutter and disturbance while maintaining accessibility to relevant content
3Adaptability or versatility
If the display mode continuously changes with distance, then the information presentation adapts to proximity, but it causes frequent switching that disturbs the worker's visual field
Solution Approach 1:
The system establishes a predetermined distance threshold that triggers the display mode switch. Rather than continuously adjusting the display mode with every small change in distance, the display control section compares the detected distance against this threshold and switches modes only when the threshold is crossed, providing stable and predictable display behavior that reduces visual disturbance while maintaining adaptive functionality

AI summary
A display system includes a portable display device; a distance detection section that detects a distance between a work object and the portable display device; and a display control section that displays object-related information, which indicates content relevant to the work object, on the portable display device. The display control section changes an object-related information display mode in the portable display device according to a result which is acquired in such a way that the distance detection section detects the distance.
