Relative-Parameter Authentication Across Connected Portable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication methods for virtual and augmented reality systems, such as using login/password or biometric data, are cumbersome and degrade the user experience, especially when transitioning between devices like headsets and computers, and lack efficient biometric data utilization due to sensor limitations and high computation costs.
Innovation Solution
A device and method that uses relative characteristic parameters between a first and second portable electronic device, such as a virtual reality headset and a joystick, to authenticate users by analyzing biometric data like arm length and gesture patterns without additional sensors, leveraging existing position and acceleration sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If login/password authentication is used in virtual reality systems, then security is provided, but user experience is degraded as users must switch from headset to computer for authentication
Solution Approach 1:
The patent replaces the mechanical interaction of typing on a keyboard with a purely virtual interaction system. The virtual keyboard is projected into the user's field of view within the virtual reality environment, allowing authentication to occur without physical device manipulation. The system uses spatial tracking of the headset and hand gestures to detect button presses on the virtual keyboard, substituting the mechanical keyboard system with an optical-tracking-based virtual interface.
Solution Approach 2:
The patent introduces a virtual keyboard as an intermediary interface between the user and the authentication system. This virtual keyboard is projected into the user's field of view and serves as a mediator that allows authentication to occur within the virtual reality environment itself, rather than requiring direct interaction with external physical devices like computers or mobile phones.
2Adaptability or versatility
If virtual keyboard is used in autonomous headsets, then portability is maintained, but authentication accuracy decreases due to unnatural interaction
Solution Approach 1:
The patent implements a dynamic virtual keyboard system that adapts its position, size, and layout based on the user's head movements, hand position, and interaction patterns. The keyboard is not static but dynamically adjusts to maintain optimal usability and accuracy. The system tracks the user's gestures and movements in real-time, dynamically mapping hand motions to keyboard button presses, thereby improving authentication accuracy while maintaining portability.
3Reliability
If biometric sensors are added to virtual reality headsets, then authentication reliability improves, but device complexity and cost increase
Solution Approach 1:
The patent makes the existing sensors in the virtual reality headset (accelerometers, gyroscopes, position trackers) multi-functional by using them not only for their primary purposes (motion tracking, spatial orientation) but also for biometric authentication. The system analyzes patterns in these sensor data streams to extract biometric information such as gait patterns, head movement characteristics, and gesture dynamics, thereby achieving reliable authentication without adding dedicated biometric sensors.
Solution Approach 2:
The patent enables the virtual reality headset to authenticate users using data that the device already collects during normal operation. The existing sensor system, designed for tracking user movement and position, is repurposed to also perform biometric verification. The headset essentially authenticates itself by analyzing its own sensor data, eliminating the need for separate authentication hardware.
4Reliability
If conventional authentication methods are used, then security is maintained, but computation costs are high due to biometric data processing
Solution Approach 1:
The patent applies partial action by using only specific features and patterns from the sensor data for authentication purposes, rather than processing the entire data stream. The system selectively extracts relevant biometric features (such as gait patterns or gesture dynamics) from the sensor data and processes only those specific elements for authentication, reducing the overall computational burden while maintaining security.

AI summary
Authentication of a user of a first electronic device, such as a communication terminal or a virtual or augmented reality headset. The first electronic device is connected to a second electronic device, the first electronic device and the second electronic device being separately portable by the user. The authentication device includes an analyser capable of checking whether a detected value of a relative characteristic parameter of the second electronic device corresponds to a stored value of this relative characteristic parameter of the second electronic device associated with an identifier of a user requiring an authentication, the relative characteristic parameter corresponding to the characteristic parameter of the second electronic device measured relative to the characteristic parameter of the first electronic device.
