AR Text Formatting via Dynamic Font and Line Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality (AR) terminal devices do not adapt to varying software and hardware parameters, leading to awkward and uncoordinated virtual information displays, resulting in a poor user experience, especially when dealing with large or small information content.
Innovation Solution
A method that acquires the field of view and resolution of an AR display device, along with the user's viewing angle, to determine a standard text width ratio, and subsequently calculates the text display font size, line height, and blank height, allowing for dynamic formatting and display of virtual information to optimize readability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If AR terminal devices use fixed display parameters, then device complexity is reduced, but adaptability to different information content sizes deteriorates
Solution Approach 1:
The patent implements dynamic display parameters by calculating font size, line height, and blank height based on actual information content size. The system dynamically adjusts these parameters rather than using fixed values, allowing the display to adapt to varying information content while maintaining a relatively simple overall device structure through algorithmic control.
Solution Approach 2:
The patent changes display parameters (font size, line height, blank height) based on the size of information content. By establishing calculation relationships between these parameters and information content characteristics, the system achieves adaptability without requiring complex hardware modifications, thus resolving the contradiction between adaptability and device complexity.
2Ease of operation
If AR terminal devices use standardized display formats, then ease of manufacture is improved, but user experience deteriorates due to poor coordination with viewing angles
Solution Approach 1:
The patent establishes calculation relationships between display parameters and viewing angles, allowing the system to automatically adjust font size, line height, and blank height based on the user's viewing angle. This parameter adaptation improves readability and coordination with the viewing angle while avoiding complex manual formatting processes, thus resolving the contradiction between ease of operation and ease of manufacture.
3Quantity of substance
If AR terminal devices display large information content, then information completeness is improved, but display coordination deteriorates due to awkward formatting
Solution Approach 1:
The patent dynamically adjusts display parameters including font size, line height, and blank height based on the size of information content. When large information content is displayed, the system automatically optimizes these parameters to maintain coordinated formatting, preventing awkward display effects while preserving information completeness.
Solution Approach 2:
The patent changes display parameters according to information content characteristics. By establishing calculation relationships between parameters and content size, the system achieves coordinated display formatting for large information content without requiring manual intervention, thus resolving the contradiction between information completeness and display coordination.

AI summary
A method for displaying augmented reality, a device, a storage medium, and a terminal are provided. A field of view and resolution of an augmented reality display device and a viewing angle of a user are acquired. A standard text width ratio of virtual information to be displayed is acquired. Then, a text display font size corresponding to the virtual information is determined according to the resolution, the field of view, the viewing angle, and the standard text width ratio. Further, a text display line height and a text display blank height corresponding to the virtual information can be determined based on the text display font size. Finally, a content of the virtual information is formatted and displayed according to the text display font size, the text display line height, and the text display blank height.
