AR Text Layout and Positioning for Limited Field of View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality (AR) systems face inefficiencies in text presentation due to inadequate analysis and understanding of input data, inferior data integration quality, and lack of interactive controls, leading to readability issues and increased cognitive load for users, particularly when consuming large amounts of textual content or poorly presented content.
Innovation Solution
A method and system for text presentation in AR devices that involves identifying layout types, restructuring text based on visual see-through (VST) parameters, user parameters, and content parameters, and optimizing text position and visibility through complexity analysis, simplification, and paraphrasing to enhance readability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If text is presented in AR devices with limited field of view, then all important textual data should be visible to users, but the text gets cropped out and useful information becomes invisible
Solution Approach 1:
The patent segments text into multiple layout types (single line, multiple lines, vertical, horizontal) and divides text content into priority-based sections. This allows the system to present different portions of text in optimized arrangements that fit within the limited AR field of view while maintaining access to all information through structured segmentation.
Solution Approach 2:
The patent introduces text occupancy per degree as a new dimensional parameter to optimize text placement. By considering text density across angular dimensions rather than just linear space, the system can arrange text to maximize visibility within the conical field of view of AR devices, preventing cropping while maintaining information completeness.
2Loss of information
If large amount of text is presented on AR display, then complete information is provided, but text becomes unreadable due to improper processing and cropping
Solution Approach 1:
The patent applies different layout qualities to different regions of text based on priority and importance. High-priority text receives optimized single-line or prominent multi-line layouts, while secondary information uses compact vertical or horizontal arrangements. This local differentiation ensures readable presentation of critical information while accommodating complete information sets within limited space.
Solution Approach 2:
The patent dynamically changes text presentation parameters including font size, line spacing, and layout configuration based on text occupancy per degree calculations. By adjusting these parameters according to the available angular space and text density, the system maintains readability while presenting complete information without improper cropping.
3Adaptability or versatility
If text is presented in real-world background environment, then contextual information is enhanced, but text becomes camouflaged and readability deteriorates
Solution Approach 1:
The patent employs color and contrast adjustments to differentiate text from real-world backgrounds. By modifying text color properties and opacity based on background analysis, the system prevents camouflaging while maintaining contextual integration, ensuring text remains readable against diverse environmental backgrounds in AR presentations.
4Ease of operation
If user moves while using VST glasses, then mobility and natural interaction are enabled, but text content shakes and becomes blurred
Solution Approach 1:
The patent implements dynamic text anchoring and stabilization mechanisms that adapt to user movement. Text elements are anchored to stable reference points in the AR environment and dynamically adjusted to maintain stability during user motion, allowing mobility while preventing shaking and blurring of text content.

AI summary
The disclosure relates to a method and a system for text presentation in an augmented reality (AR) based device. The method comprises: identifying one or more layout types for a complete text; restructuring the complete text based on one or more visual see through (VST) parameters, the one or more layout types, and a text occupancy per degree value; identifying a text position for the restructured text based on at least one of: one or more user parameters, one or more user activities, and the one or more VST parameters; and presenting the restructured text based on the identified text position.
