Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current VR systems use cumbersome user interfaces for authentication, such as virtual keyboards and hand gestures, which are complicated and inefficient.
Innovation Solution
A multi-factor authentication method using a head-mounted display (HMD) that combines password entry via a virtual keyboard and biometric fingerprint collection through predefined head gestures, including a randomized keypad layout and biometric fingerprint measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a virtual keyboard with hand gesture recognition or wand pointing is used for authentication, then password entry capability is provided, but the user interface becomes complicated and cumbersome
Solution Approach 1:
The patent combines password entry and biometric authentication into a single integrated head gesture interface. Users enter passwords and provide biometric verification through unified head movements, eliminating the need for separate hand gesture recognition or wand pointing mechanisms. This merging of functions simplifies the overall authentication process while maintaining security.
Solution Approach 2:
The patent replaces manual hand gestures and wand pointing with head gesture recognition. By substituting the mechanical interaction of hands and wands with automated head movement detection, the system reduces user effort and interface complexity while improving ease of operation.
2Reliability
If multi-factor authentication is implemented, then security is enhanced, but the authentication process becomes more complex
Solution Approach 1:
The patent merges password-based authentication and biometric authentication into a single unified process using head gestures. Both authentication factors are collected through the same interface mechanism, reducing the perceived complexity for users while maintaining the security benefits of multi-factor authentication.
Solution Approach 2:
The head gesture recognition system serves multiple functions: it enables password entry, provides biometric verification, and maintains session security. This universal interface handles all authentication requirements through a single mechanism, simplifying the overall process while enhancing security.
3Ease of operation
If head gestures are used for both password entry and biometric collection, then ease of operation is improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The patent replaces complex hand gesture recognition with simpler head gesture detection. Head movements are easier to detect and measure using standard sensors compared to subtle hand gestures, reducing the technical difficulty while improving user experience.
Solution Approach 2:
The system automatically captures biometric data from head gestures without requiring separate biometric devices. The authentication process serves itself by using the same natural head movements for both password entry and biometric verification, reducing measurement complexity.
