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 patent replaces traditional mechanical input devices (keyboards, mice, buttons) with voice-based and gesture-based input systems. The voice processor captures and interprets spoken commands, while the gesture processor tracks hand movements through camera and sensor data, eliminating the need for physical interaction devices and enabling more intuitive XR interaction.
Solution Approach 2:
The head-wearable apparatus integrates multiple input modalities (voice, gestures, touch) into a single unified system. The processor can switch between different input types based on context, and the system supports various interaction paradigms including hand-centric, near-field, and far-field interfaces, making the device versatile across different application scenarios.
2Adaptability or versatility
If multiple input modalities are integrated, then interaction flexibility improves, but system complexity increases
Solution Approach 1:
The patent combines voice processing, gesture recognition, and touch input capabilities into a single integrated processor system. The processor coordinates these different input modalities, allowing them to work together seamlessly and switch between them based on the current interaction context, thereby managing complexity through unified architecture.
Solution Approach 2:
The processor acts as an intermediary that translates various input modalities (voice commands, gesture movements, touch inputs) into standardized control signals that the XR system can understand and execute. This mediation layer simplifies the integration of multiple input types by providing a common interface between diverse input sources and the core system.
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:
The patent implements dynamic user interface elements that can change their position, size, and content based on the user's current context, activity, and environmental conditions. The processor continuously adjusts the display of virtual objects and interface elements to optimize their relevance and accessibility, transforming static UI components into adaptive, context-aware displays.
Solution Approach 2:
Different regions of the display are assigned different functions and characteristics based on their utility for specific tasks. The system can prioritize certain areas of the field of view for specific types of information or interactions, allowing important interface elements to be positioned in optically determined locations that maximize user attention and interaction efficiency.
Data Source
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.
