Successive Color Field Alignment for World-Locked AR Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing artificial reality systems face misalignment issues due to user movement, such as head and eye movement, causing visual artifacts when displaying virtual objects through successive color fields.
Innovation Solution
Implement a color field manager that adjusts the display location of successive color fields based on detected user movement, ensuring alignment from the user's perspective to mitigate misalignment and improve clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If successive color fields are displayed to render a virtual object, then color information is improved, but misalignment occurs due to user movement
Solution Approach 1:
The system dynamically adjusts the display location of successive color fields based on detected user movement. The color field manager modifies the position of each color field in real-time to compensate for head and eye movements, transforming a static display system into a dynamic one that adapts to user motion.
Solution Approach 2:
The system uses sensor data providing feedback about user movement to adjust the display location of color fields. The color field manager continuously receives movement information and uses this feedback to reposition color fields, creating a closed-loop control system that maintains alignment despite user motion.
2Manufacturing precision
If display location is adjusted based on user movement, then alignment precision is improved, but computational complexity increases
Solution Approach 1:
The system performs preliminary actions by detecting user movement and calculating adjusted display locations before rendering each successive color field. The color field manager prepares the corrected positions in advance, ensuring alignment is maintained without requiring complex real-time adjustments during the actual display process.
3Loss of information
If multiple color fields are displayed successively, then color fidelity is improved, but visual artifacts increase due to misalignment
Solution Approach 1:
The system applies preliminary anti-action by pre-calculating and applying compensatory position adjustments to counteract the expected misalignment caused by user movement. The color field manager proactively positions each color field to prevent misalignment artifacts before they occur, rather than attempting to correct them after they appear.

AI summary
Aspects of the present disclosure are directed to displaying color fields over time by an artificial reality system. A method includes causing a head-wearable device worn by a user to present a virtual object by successively displaying a plurality of color fields including presenting a first color field and a second color field at a first display position so that the virtual object is at a world-locked location as viewed by the user from a first perspective. The method includes, in accordance with a determination, based on user motion data, that misalignment criteria are satisfied causing the head-wearable device to present the virtual object by successively displaying the plurality of color fields including presenting the first and/or second color fields of the virtual object at a second display position so that the virtual object is at the world-locked location as viewed by the user from a second perspective.
