Text Display Duration Control for Wearable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices with small digital display areas face challenges in effectively displaying text information due to limited space, as rapid scrolling makes it difficult to read and slow scrolling takes too long to display a paragraph.
Innovation Solution
A method that divides text into substrings, determines a complexity index for each substring, and displays each substring for a duration based on its complexity index, with adjustments to smooth the display time based on neighboring substrings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If text is scrolled quickly across the display area, then the display time is reduced, but it becomes difficult for users to read the text information
Solution Approach 1:
The patent divides a string of text into multiple substrings and displays them sequentially rather than scrolling the entire text at once. This segmentation allows each substring to be displayed for an optimized duration that balances reading comprehension with overall display efficiency, resolving the contradiction between display speed and readability.
Solution Approach 2:
The patent dynamically adjusts the display duration of each substring based on its complexity index. Substrings with higher complexity (more characters, unfamiliar words) are displayed longer, while simpler substrings are displayed shorter. This dynamic adjustment optimizes the balance between display speed and readability for each segment of text.
2Ease of operation
If text is scrolled slowly across the display area, then readability is improved, but a paragraph of text information takes a long time to be fully displayed
Solution Approach 1:
By segmenting text into substrings, the system can apply different display durations to different segments. This allows the overall display time to be reduced while maintaining adequate display time for each individual substring, thus improving productivity without sacrificing readability.
Solution Approach 2:
The patent changes the parameter of display duration based on the complexity index of each substring. This parameter adjustment allows the system to optimize display time for each segment, reducing the total display time for a paragraph while ensuring each substring is displayed long enough to be read comfortably.
3Area of stationary object
If the display area is made larger to accommodate more text, then text information can be displayed without scrolling, but the wearable device becomes less compact and less aesthetically pleasing
Solution Approach 1:
Instead of expanding the display area spatially, the patent utilizes the time dimension by displaying substrings sequentially. This allows more text information to be presented on a small display area without requiring the device to be larger, maintaining compactness while increasing information capacity through temporal expansion.
