Solution Overview
Problem
Extended reality (XR) systems face challenges in providing intuitive and efficient user interfaces, particularly in integrating multiple input modalities like voice, gestures, and touch, and transitioning between different interaction paradigms, which hinders usability and adoption across various applications.
Innovation Solution
An XR system provides a body-centric XR user interface located on the user's hand, integrating hand gestures, touch interactions, voice input, and visual capture, with adaptive positioning and AI assistance to enhance user interaction flexibility and context relevance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional user interfaces are used in XR systems, then the system structure remains simple, but the user interface intuitiveness and interaction efficiency deteriorate
Solution Approach 1:
The user interface is segmented into multiple input modalities (voice, gestures, touch) and processing stages (capture, processing, execution). Each modality and stage can be independently optimized and configured, allowing complex interaction capabilities while maintaining manageable system structure through modular design.
Solution Approach 2:
The XR system implements a universal interface framework that handles multiple input modalities (voice commands, hand gestures, touch interactions) through a common processing architecture. This multi-functional design allows the same system structure to support diverse interaction types, improving ease of operation without proportionally increasing complexity.
2Adaptability or versatility
If multiple input modalities are integrated, then interaction flexibility improves, but system complexity increases
Solution Approach 1:
An intermediary processing layer is introduced between the various input modalities and the command execution system. This mediator captures inputs from voice, gestures, and touch channels, processes them through a unified framework, and translates them into executable commands. This intermediary structure enables flexible multi-modal interaction while containing system complexity through centralized processing logic.
Solution Approach 2:
The system implements dynamic input processing where the available modalities and their processing priorities can adapt based on context. The interface can dynamically enable or disable certain input channels, adjust processing sensitivity, and reconfigure interaction paradigms based on user behavior and environmental factors, providing flexibility without requiring permanent complex structures for all possible modalities.
3Adaptability or versatility
If fixed user interface elements are used, then the display structure remains simple, but the user interface adaptability to different contexts deteriorates
Solution Approach 1:
User interface elements are designed to be dynamic rather than fixed, allowing them to change position, size, and visibility based on contextual factors such as user location, activity type, and environmental conditions. The display system can dynamically reconfigure UI layouts and adjust element properties to optimize usability for different contexts without requiring multiple fixed display structures.

AI summary
An extended Reality (XR) system is provided that generates a dynamic XR user interface having a variety of user input modalities and types of XR user interfaces. The XR system provides a body-centric XR user interface on a hand of the user including a first interactive virtual object located on the hand. The XR system detects a first selection of the first interactive virtual object and provides a near-field XR user interface including a second interactive virtual object. The XR system detects a second selection of the second interactive virtual object and configures the near-field XR user interface to capture a user input. The XR user interface, captures the user input using the near-field XR user interface, generates content for a far-field XR user interface, provides the far-field XR user interface to the user, and displays the content to the user using the far-field XR user interface.
