XR Headset Privacy Authentication via Segmented Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extended reality (XR) devices require users to expose their private information entry on external screens, making it difficult to authenticate securely in public environments, as others can observe the credentials being entered.
Innovation Solution
An XR system using a head-mounted device (HMD) with a private display and motion detection, displaying different authentication images to the user and others, allowing users to select sequences of images via gestures without revealing their selections to external observers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If authentication credentials are displayed on external screens for user input, then ease of operation is improved, but security is worsened as others can observe the credentials being entered
Solution Approach 1:
The patent divides the display into two separate displays: a public external display showing a first set of images and a private HMD display showing a second set of images. This segmentation allows the authentication interface to be split between public and private viewing areas, enabling users to input credentials on the public screen while their selections remain visible only to them through the HMD, thus resolving the contradiction between ease of operation and security
Solution Approach 2:
The HMD acts as an intermediary device that provides private visual feedback to the user during authentication. The motion detection device detects head movements and correlates them with image selections on the public display, serving as a mediator that translates private user intent into public authentication input without exposing the credentials to others
2Reliability
If motion detection is used to detect head movements for authentication, then security is improved, but device complexity is worsened
Solution Approach 1:
The HMD serves multiple functions: it displays private authentication images, houses the motion detection device, and provides the authentication interface. By making the HMD a multi-functional device that combines display, motion detection, and authentication capabilities, the patent reduces overall system complexity while maintaining security

AI summary
In an example implementation according to aspects of the present disclosure, a XR system comprises an HMD which includes an HMD display and a motion detection device, an external display of a computing device, and a processor operatively coupled with a computer readable storage medium and instructions stored on the computer readable storage medium that, when executed by the processor, direct the processor to detect an activation of a privacy mode; display, by the HMD display, a first series of images to a user of the HMD; display, by the external display, a second series of images to other users; capture, by the motion detection device, movements of the user selecting a sequence of images of the first series of images displayed on the HMD display; and authenticate the user based on the movements of the user.
