Mixed Reality Object Lock Transition for Stable Spatial Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual object display technologies in mixed reality environments struggle to maintain the spatial relationship between virtual objects and their physical counterparts as the electronic device moves, leading to inconsistencies in object positioning.
Innovation Solution
The method involves rendering virtual objects as device-world-locked or physical-world-locked objects by transforming coordinates between different reference frames, allowing objects to maintain their spatial relationship with the physical environment or virtual space during device movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If virtual objects are displayed as device-locked objects with fixed display coordinates, then the rendering is simple and fast, but the spatial relationship with the physical environment becomes inconsistent during device movement
Solution Approach 1:
The patent applies dynamics by enabling virtual objects to transition between two display modes: device-locked mode (fixed to display coordinates) and world-locked mode (fixed to physical space coordinates). This dynamic switching allows the system to optimize between rendering speed and spatial consistency based on operational context, resolving the contradiction between fast rendering and consistent spatial relationships.
2Reliability
If virtual objects are displayed as world-locked objects maintaining spatial position in physical environment, then the spatial relationship consistency is improved, but the rendering complexity increases
Solution Approach 1:
The patent introduces a transition trigger mechanism as an intermediary that mediates between device-locked and world-locked display modes. This trigger detects specific conditions (such as device movement thresholds or user interactions) and automatically switches the display mode accordingly, simplifying the complexity by providing clear transition criteria rather than requiring continuous complex coordinate transformations.
3Measurement precision
If the system continuously tracks device movement to maintain accurate virtual object positioning, then the spatial accuracy is improved, but the computational overhead and energy consumption increase
Solution Approach 1:
The patent implements periodic action by using transition triggers that activate world-locked mode only when specific conditions are met (such as significant device movement or entry into certain virtual/physical zones). Instead of continuous tracking and transformation, the system periodically evaluates transition conditions and switches modes accordingly, reducing computational overhead and energy consumption while maintaining positioning accuracy when needed.

AI summary
In one implementation, a method of displaying a virtual object is performed at a device in a physical environment, the device having a display, one or more processors, and non-transitory memory. The method includes displaying, on the display, a virtual object as a device-world-locked virtual object in a three-dimensional virtual portion of a mixed reality environment. The method includes detecting a device-world-to-physical-world transition trigger. The method includes, in response to detecting the device-world-to-physical-world transition trigger, displaying the virtual object as a physical-world-locked virtual object in a three-dimensional real portion of the mixed reality environment corresponding to at least a portion of the physical environment.
