XR Component Manipulation and Assembly Through Hand Gestures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manipulating component parts of objects represented by extended-reality (XR) models is challenging, particularly in computer-aided design, due to limitations in visualization and interaction on traditional devices, and extended-reality headsets have not fully addressed these needs.
Innovation Solution
Users wearing extended-reality headsets can interact with XR objects using hand gestures to manipulate, annotate, and build component parts in an immersive environment, with features like XR modes for assembly, measurement, annotation, and collaboration, allowing structurally correct coupling of parts and real-time interaction with others.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional devices (laptops, desktop computers) are used for design applications, then users can interact with XR models, but the visualization and manipulation capabilities are limited
Solution Approach 1:
The patent transitions from 2D screen-based interaction to 3D spatial interaction by presenting XR models in extended reality environments. Users can manipulate components in three-dimensional space using hand gestures, providing immersion and interaction quality that traditional 2D devices cannot achieve.
Solution Approach 2:
The patent replaces traditional mechanical input devices (mouse, keyboard, trackpad) with hand gesture-based interaction. The system detects and interprets hand gestures in 3D space to control XR model manipulation, eliminating the need for physical contact with display surfaces and enabling more natural interaction.
2Adaptability or versatility
If extended-reality headsets are used for design applications, then immersive interaction is achieved, but the ability to accurately manipulate and assemble component parts is limited
Solution Approach 1:
The system provides real-time visual feedback by displaying XR representations of component parts and their correct assembly positions. When users bring physical components near the designated locations, the system detects their positions and provides guidance, enabling accurate assembly through continuous feedback loops between the user's actions and the XR display.
Solution Approach 2:
The XR model serves as an intermediary between the physical component parts and the user's manipulation actions. The system translates physical hand gestures into transformations of the XR model, and vice versa, providing a mediator that enables precise control and assembly guidance in the extended reality environment.
3Ease of operation
If hand gestures are used to manipulate XR components, then natural interaction is achieved, but the complexity of gesture recognition and mode switching increases
Solution Approach 1:
The patent segments interaction into distinct XR modes (e.g., manipulation mode, assembly mode, annotation mode). Each mode has specific gesture protocols, making the gesture recognition system more manageable. The system switches between modes based on contextual cues, reducing the complexity of any single gesture recognition task.
Solution Approach 2:
The system performs preliminary actions by establishing the current XR mode and displaying relevant guidance information before requiring gesture input. This preparation reduces the cognitive load on users and simplifies gesture recognition, as the system knows what actions are expected in the current mode.
4Adaptability or versatility
If multiple XR modes are implemented for different manipulation tasks, then functionality is enhanced, but the system complexity and mode switching overhead increase
Solution Approach 1:
The XR headset and associated computing device serve multiple functions across different modes (manipulation, assembly, measurement, annotation). A single hardware platform supports diverse interaction paradigms by software configuration, reducing the need for separate specialized devices for each function.
Solution Approach 2:
The system dynamically adapts its behavior based on the current XR mode and user actions. Mode transitions are triggered by contextual conditions rather than explicit user commands, making the switching process seamless and reducing perceived complexity. The system maintains appropriate guidance and interaction protocols automatically during mode changes.

AI summary
A method of interacting with extended reality (XR) objects within a computer aided design is described. The method includes, while presenting an XR representation of an object and in response to a first gesture, initiate a first XR mode that allows the user to manipulate a plurality of component parts of the object within the XR representation. The method includes, in response to a second gesture directed to a component part of the plurality of component parts of the XR representation, cause a manipulation to the component part. The method includes, in response to a third hand gesture, initiate a second XR mode, the second XR mode causing presentation of an XR augment that defines a boundary. The method further includes, in response to movement of at least one component part to within a threshold distance of the boundary, coupling together the plurality of component parts to form the object.
