Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing XR systems face issues with user fatigue, privacy concerns, and inefficient resource utilization due to the reliance on direct physical or vocal interactions with secondary devices, leading to a fragmented user experience and potential security risks.
Innovation Solution
The system enables XR devices to unlock secondary devices using biometric data without user intervention, maintains privacy by powering off the secondary device display, and allows input through a virtual keyboard overlay, optimizing battery use and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the secondary device remains unlocked for extended use as an input mechanism, then ease of operation is improved, but security and privacy deteriorate due to potential unauthorized access and visible notifications
Solution Approach 1:
The system performs preliminary authentication by capturing biometric data (facial recognition) before unlocking the secondary device. This allows the device to remain unlocked during the XR session without security risk, as the user is already verified. The authentication happens in advance through the XR device's camera and processing capabilities.
Solution Approach 2:
The XR device acts as an intermediary between the user and the secondary device. It captures biometric data, performs authentication, and communicates authentication status to the secondary device. This intermediary role enables secure unlocked operation by mediating the trust relationship without requiring the user to continuously interact with the secondary device.
2Object-affected harmful factors
If the user continuously exits the XR environment to unlock the secondary device, then security is improved, but productivity and user experience deteriorate due to fragmented interaction and wasted time
Solution Approach 1:
The system performs authentication in advance through facial recognition captured by the XR device before the user needs to access the secondary device. This preliminary action eliminates the need for repeated interruptions to unlock the device, maintaining security while enabling continuous productive interaction within the XR environment.
Solution Approach 2:
The system enables self-service authentication where the user's biometric data is automatically captured and processed by the XR device without requiring manual intervention. The secondary device unlocks automatically based on the authenticated status, eliminating the need for the user to manually unlock the device during XR sessions.
3Ease of operation
If the display of the secondary device remains on during XR use, then usability is improved by allowing the user to see inputs, but privacy and energy consumption worsen due to visible notifications and increased power usage
Solution Approach 1:
The system transitions the display interface from the physical secondary device to the virtual XR environment. Instead of relying on the secondary device's physical display, the XR device renders a virtual representation of the secondary device interface within the immersive environment. This dimensional shift allows the physical display to remain off (saving energy and protecting privacy) while maintaining full usability through the virtual interface.
Solution Approach 2:
The system creates a virtual copy or representation of the secondary device interface within the XR environment. This copy includes the keyboard and input interface, allowing the user to interact with the secondary device through the virtual representation without needing the physical display to be visible or powered on.
4Object-affected harmful factors
If the user removes the HMD to interact with the secondary device, then privacy is improved by seeing the device clearly, but immersion and ease of operation deteriorate
Solution Approach 1:
The system moves the interaction interface from the external physical world to the internal virtual XR environment. The user can see and interact with the secondary device representation through the HMD without removing it, maintaining immersion while protecting privacy since the physical display remains off or obscured.
Solution Approach 2:
The system creates a virtual copy of the secondary device interface that is visible within the XR environment through the HMD. This allows the user to see the keyboard and input interface clearly through the immersive display without needing to remove the HMD or expose the physical secondary device display to view.

AI summary
An extended reality (XR) head-mounted device (HMD) is disclosed. The XR HMD comprises input/output (I/O) circuitry and control circuitry, where the control circuitry is configured to provide an application to a user wearing the XR HMD, connect the XR HMD to at least one mobile device associated with the user based on input capabilities of the mobile device, and wherein the I/O circuitry is configured to establish a connection between the mobile device and the XR HMD and wherein the control circuitry is further configured to cause the mobile device to be unlocked, receive an indication of input from the mobile device, and based on the received indication of input, perform an action in relation to the application being provided via the XR HMD.
