Solution Overview
Problem
Existing virtual and augmented reality interfaces face challenges in providing a consistent user experience due to their reliance on real-world objects, making it difficult to transition between interface modes in a way that is understandable to a wide variety of users.
Innovation Solution
A method and apparatus that detect the orientation of a user interface using an imaginary vector intersecting an imaginary sphere, allowing for seamless transitions between viewing modes such as virtual/augmented reality and control modes by determining the three-dimensional orientation and managing the display accordingly, using sensors like IMUs and GPS for location and orientation data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If interface elements are tied to real world objects to provide contextual relevance, then the interface becomes more meaningful in specific environments, but the interface consistency deteriorates across different environments
Solution Approach 1:
The interface dynamically transitions between different modes (AR mode, VR mode, control mode) based on device orientation. The system uses sensors to detect orientation changes and automatically switches interface elements and interactions accordingly, allowing the interface to adapt to different environments while maintaining consistency within each mode
Solution Approach 2:
The system changes interface parameters (viewing mode, interaction type, display orientation) based on detected device orientation parameters. By monitoring orientation angles and thresholds, the system transitions between operational modes to balance environmental adaptability with interface consistency
2Adaptability or versatility
If multiple viewing modes are provided to enhance functionality, then the system becomes more versatile, but the device complexity increases
Solution Approach 1:
The interface is segmented into distinct operational modes (AR mode, VR mode, control mode), each with specific functions and interface elements. This segmentation allows the system to provide multiple viewing modes while managing complexity by clearly defining the scope and behavior of each mode separately
Solution Approach 2:
The system dynamically switches between segmented modes based on orientation detection, providing versatility when needed while simplifying the interface by activating only one mode at a time. The automatic transition mechanism manages complexity by eliminating the need for manual mode selection
3Ease of operation
If automatic mode switching is implemented to improve ease of operation, then user effort is reduced, but the system complexity increases
Solution Approach 1:
The system performs self-service by automatically detecting device orientation and switching modes without user intervention. The orientation detection system and mode transition logic are built into the system, allowing it to manage its own operational state based on environmental conditions
Solution Approach 2:
The system uses feedback from orientation sensors to automatically adjust the operational mode. By continuously monitoring device orientation and comparing it against predefined thresholds, the system makes automatic decisions about mode transitions, reducing user effort while managing complexity through sensor-based control
