Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional physical controllers or gesture recognition technologies are used for XR interaction, then device complexity is reduced, but user satisfaction and interaction precision deteriorate due to imprecise gesture recognition and non-intuitive interfaces
Solution Approach 1:
The patent introduces virtual objects displayed on the user's hands as an intermediary between the user and the XR system. These virtual objects serve as a mediator that translates natural hand movements into precise digital commands, resolving the contradiction between simple interaction and precise control without requiring complex physical controllers
Solution Approach 2:
The patent replaces traditional mechanical controllers with a visual interface system that uses displayed virtual objects and hand tracking. This substitution eliminates the need for physical mechanical interfaces while providing more precise and intuitive interaction, thereby improving user satisfaction without increasing device complexity
2Measurement precision
If hand-tracking with virtual objects displayed on hands is implemented, then interaction precision and intuitiveness improve, but device complexity increases due to advanced tracking and rendering requirements
Solution Approach 1:
The patent makes the user's hands serve multiple functions: they are both the interface for interaction and the display medium for virtual objects. This multi-functionality allows the system to achieve high precision gesture recognition and intuitive interaction without adding separate complex display devices or controllers
Solution Approach 2:
The system uses the user's own hands as the interface, eliminating the need for external controllers. The hands naturally provide the interaction surface while the virtual objects displayed on them provide the interface elements, creating a self-service system that reduces overall device complexity
3Ease of operation
If interactive virtual objects are displayed on the user's hands, then ease of operation improves through natural gestures, but manufacturing precision requirements increase for accurate hand-tracking and display alignment
Solution Approach 1:
The patent transitions from 2D screen interaction to 3D spatial interaction by displaying virtual objects in the user's field of view anchored to their hands. This dimensional change allows for more natural gestures while the system handles the complexity of 3D tracking and alignment through software algorithms rather than requiring extreme manufacturing precision
4Productivity
If traditional interfaces are used for XR system control, then device complexity is minimized, but productivity decreases due to user frustration and reduced efficiency in professional environments
Solution Approach 1:
The patent implements a dynamic interface where virtual objects are displayed on the user's hands and move with hand movements. This dynamic interaction allows users to efficiently manipulate digital content in professional environments through natural gestures, significantly improving productivity compared to static traditional interfaces
Data Source
AI summary
An XR system is provided that enhances user interaction within an extended reality environment by capturing tracking data of a user's hands using one or more sensors. The XR system uses this data to generate a system control user interface that includes interactive virtual objects positioned on a first hand of the user, which the user can interact with using a digit of a second hand. The system control user interface is displayed directly to the user. Upon detecting a system control input from the user, the XR system generates and displays a system function user interface that includes further interactive virtual objects for accessing various system functions. These interfaces are displayed simultaneously yet separately within the user's field of view.
