Integrated Scrollwheel and Fingerprint Sensor for AR VR Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch sensors and fingerprint sensors are unsuitable for augmented reality (AR) and virtual reality (VR) environments, where users cannot conveniently see the input devices they are interacting with, leading to difficulties in navigation and authentication.
Innovation Solution
An integrated scrollwheel and fingerprint sensor (FPS) user input apparatus is provided, where the scrollwheel detects rotational navigation inputs and the FPS detects biometric inputs, allowing for seamless navigation and authentication within the AR or VR system, even when the user cannot see the input device. This apparatus is physically integrated into a housing with a display, enabling intuitive user interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional touch sensors and fingerprint sensors are used in AR/VR systems, then the system can provide user interface functionality, but the user cannot conveniently interact with the system because they cannot see the input device
Solution Approach 1:
The patent combines the fingerprint sensor and scrollwheel into a single integrated input device. The fingerprint sensor is positioned at the center of the scrollwheel, allowing users to perform both biometric authentication and navigation functions at the same location without needing to look at or locate separate input devices.
Solution Approach 2:
The integrated device serves multiple functions: the fingerprint sensor area can be used for both authentication and as a reference point for scrollwheel navigation, while the scrollwheel provides both rotational navigation input and a physical guide for finger placement. This multi-functionality eliminates the need for users to locate separate input devices.
2Device complexity
If the fingerprint sensor and scrollwheel are integrated into a single apparatus, then the device complexity is reduced and user interaction is simplified, but the manufacturing precision requirements increase
Solution Approach 1:
By merging the fingerprint sensor and scrollwheel into a single integrated apparatus, the patent reduces the number of separate components that need to be positioned and aligned. The fingerprint sensor is built directly into the scrollwheel structure, eliminating the need for separate mounting and alignment procedures between two distinct devices.
Solution Approach 2:
The fingerprint sensor is nested within the scrollwheel structure, with the sensor area positioned at the center of the scrollwheel's sensing region. This nested configuration allows the smaller fingerprint sensor to be integrated within the larger scrollwheel apparatus, simplifying assembly while maintaining functional integration.

AI summary
A virtual reality (VR) or augmented reality (AR) system includes: a display configured to display a user interface to a user; an integrated scrollwheel and fingerprint sensor (FPS) user input apparatus, comprising a scrollwheel configured to detect a rotational navigation input from the user and an FPS configured to detect a biometric input from the user; and a processing system configured to: receive the rotational navigation input via the scrollwheel of the integrated scrollwheel and FPS user input apparatus; update a displayed user interface on the display based on the received rotational navigation input, wherein updating the displayed user interface comprises updating a user selection on a displayed menu; receive an activation input for the updated user selection on the displayed menu via the FPS of the integrated scrollwheel and FPS user input apparatus; and execute an operation corresponding to the updated user selection on the displayed menu.
