XR 3D Object Base Plate Rendering for Clearer Manipulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manipulating 3D objects in XR environments fail to address user interactions with irregularly shaped objects, particularly in XR environments, where existing technologies fail to efficiently guide a user on how to change or resize volumes of 3D objects due to unclear boundaries, especially in extended reality (XR) environments like VR and AR, making user interaction difficult.
Innovation Solution
A base plate, or ornament, is introduced around the bottom surface of a 3D object in XR environments to provide a visual boundary, with a partially displayed section highlighted based on user gaze, allowing resizing and repositioning through user interfaces, and grabbers to interact with the object, while multiple layers and interaction orders handle overlapping objects.

Engineering Contradiction Analysis
1Ease of operation
If a base plate is displayed around irregularly shaped 3D objects in XR environments, then the visual boundary becomes clear and user interaction is improved, but the device complexity and rendering requirements increase
Solution Approach 1:
The base plate is segmented into multiple portions, each associated with different manipulation functions (resize, reposition, rotate). Each portion can be independently controlled and displayed based on user gaze direction, allowing the system to show only relevant portions rather than the entire base plate, thus reducing rendering complexity while maintaining ease of operation.
Solution Approach 2:
Different portions of the base plate have different visual properties and functions. The portion corresponding to the bottom surface provides a visual boundary, while other portions provide manipulation controls. The system dynamically adjusts which portions are displayed based on user gaze, applying local quality changes to optimize both usability and rendering efficiency.
2Ease of operation
If base plates and grabbers are dynamically displayed based on user gaze, then distraction is reduced and user experience is improved, but the measurement precision of gaze detection and interaction timing must be high
Solution Approach 1:
The system continuously monitors user gaze direction and dynamically adjusts the display of base plate portions and grabbers in real-time. When the user gazes at a specific portion, that portion becomes highlighted or visible, providing immediate visual feedback. This feedback loop requires precise gaze detection but creates an intuitive, distraction-free interaction experience where users naturally understand which object or portion is selectable based on visual cues.
3Manufacturing precision
If multiple layers and interaction orders are used to handle overlapping objects, then object manipulation accuracy is improved, but the device complexity increases
Solution Approach 1:
The system resolves overlapping object conflicts by introducing a temporal dimension through interaction order. Instead of solely relying on spatial layering, objects are processed in the order they are selected or activated by the user. This allows a later-created object to be manipulated even if it appears behind an earlier object, providing accurate manipulation while simplifying the mental model of layer management.

AI summary
Techniques are disclosed for rendering an ornament for a 3D object in a 3D environment displayed on a headset device and providing a user interface to manipulate the 3D object. In some embodiments, a user's input may be tracked. An ornament (e.g., base plate or a portion of the base plate) may be displayed adjacent to a volume associated with a 3D object in response to determining whether the user's input is within a threshold distance from the 3D object or a surface of its associated volume. In some embodiments, a visual display of a portion of the base plate may be altered, or a manipulation object or both may be displayed for manipulating the 3D object in response to the user's input within the threshold distance.
