Dynamic Display Format Adjustment for Eye Strain Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prolonged viewing of content on electronic devices with fixed font and image sizes can cause eye strain due to lack of eye refocusing and head movement, necessitating a method to dynamically adjust the display format.
Innovation Solution
An electronic device system with modules for face recognition, distance measurement, visual acuity determination, and display format adjustment, which changes font and image sizes based on viewer distance and visual acuity, and incorporates timers to periodically alter the display format and content location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display format is kept fixed (font size and image size remain constant), then the device operation is simple and stable, but the viewer experiences eye strain due to lack of eye refocusing and head movement
Solution Approach 1:
The patent applies dynamics by making the display format adjustable and changeable over time. The system dynamically modifies font sizes, image sizes, and content locations based on viewer distance and visual acuity measurements, transforming a static display into an adaptive one that responds to viewer conditions to prevent eye strain
Solution Approach 2:
The patent implements periodic action through timers that periodically alter the display format and content locations even when viewer conditions remain stable. This periodic change forces the viewer to refocus and move their head, preventing eye strain caused by prolonged viewing of unchanging content
2Object-affected harmful factors
If the display format is dynamically adjusted based on viewer conditions, then eye strain is reduced, but the device complexity increases due to multiple sensing and control modules
Solution Approach 1:
The patent applies universality by designing an integrated system where a single controller coordinates multiple functions: face recognition, distance measurement, visual acuity determination, and display format adjustment. This multi-functional approach reduces overall system complexity compared to having separate independent systems for each function
Solution Approach 2:
The system applies self-service by automatically detecting viewer conditions and adjusting display parameters without requiring manual user input. The face recognition module automatically identifies the viewer, the distance measurement and visual acuity determination are performed automatically, and the display format is adjusted autonomously based on detected conditions

AI summary
A display format adjustment system includes a display control module, a distance measurement module, a timer controller, and a display format determination module. The display control module displays content in a first display format on a display. The distance measurement module continuously measures the current distance between a viewer and the display screen. The timer controller starts a timer. Once the current distance changes, the timer controller restarts the timer. If the timer reaches a predetermined time, the display format determination module determines a second display format based on the first display format and the display control module displays the content in the second display format.
