Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional authentication interfaces are used in augmented reality environments, then user authentication can be performed, but the interaction becomes cumbersome and creates significant cognitive burden on users
Solution Approach 1:
The patent replaces conventional mechanical interaction methods (physical keyboards, mice, touchscreens) with gaze-based selection and voice commands. The system detects user gaze direction using eye-tracking sensors and automatically selects UI elements when the gaze dwells on them for a specified duration, eliminating the need for manual navigation through complex authentication interfaces.
Solution Approach 2:
The authentication system performs automatic authentication attempts based on detected user intent through gaze and voice inputs. The interface adapts to user needs by presenting relevant authentication options without requiring users to manually search or navigate through multiple screens, making the system serve the user rather than requiring the user to control the system.
2Reliability
If multiple input steps are required for authentication, then security can be maintained, but the authentication process takes longer and wastes energy in battery-operated devices
Solution Approach 1:
The system performs preliminary authentication checks by continuously monitoring user gaze patterns and voice inputs even before the user explicitly initiates authentication. When the system detects that the user is looking at the authentication interface and provides voice confirmation intent, it pre-preps authentication options and can automatically proceed with authentication once confidence thresholds are met, reducing the perceived time required.
Solution Approach 2:
The patent implements a tiered authentication approach where lower-security contexts allow for faster, simplified authentication (partial action) while maintaining security in higher-risk contexts. The system can authenticate users with fewer input steps when the device is in a trusted state or when using multiple simultaneous biometric modalities, balancing security requirements with time efficiency.
3Measurement precision
If complex manipulation of virtual objects is required, then precise control can be achieved, but the process becomes tedious and error-prone
Solution Approach 1:
The patent introduces virtual hand avatars and gesture recognition as intermediaries between user intent and object manipulation. Users perform simple physical gestures in the air, and the system's gesture recognition algorithms translate these into precise virtual object manipulation commands, maintaining control precision while dramatically simplifying the physical actions required.
Solution Approach 2:
The system creates virtual copies of the user's intended actions through gaze-based selection and voice command interpretation. Instead of requiring precise manual manipulation, the user gazes at the target object and issues a simple voice command, and the system creates and executes the appropriate manipulation action, reducing errors while maintaining precision.
