Transmissive Privacy Glasses for Public-Location Data Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable information handling systems fail to adequately secure confidential information from unauthorized viewing in public locations, despite conventional privacy measures that can be easily circumvented.
Innovation Solution
A system and method that uses privacy glasses with a transmissive display to overlay secure content onto a main display, managed by sensors and touch detection surfaces to ensure secure content is only visible through the glasses, while allowing seamless interaction with both displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional privacy screen filters are used to narrow the field of view, then third party viewing is prevented, but determined third parties can still make out sensitive information and the field of view is restricted for the user
Solution Approach 1:
The patent transitions from a 2D display plane to a 3D spatial dimension by projecting secure content into the user's visual field through augmented reality glasses. This allows the secure content to be viewed in three-dimensional space rather than confined to a flat screen, enabling privacy protection without restricting the user's field of view since the content follows the user's gaze naturally.
Solution Approach 2:
The patent introduces augmented reality glasses as an intermediary device between the information handling system and the user's eyes. This intermediary projects secure content directly into the user's field of view, acting as a mediator that protects sensitive information from third parties while maintaining full visibility for the authorized user without the need for physical privacy screens.
2Object-affected harmful factors
If display brightness or contrast is reduced to improve security, then sensitive information is harder to see, but secure content is still visible to third parties when insecure environments are detected
Solution Approach 1:
The patent segments the display content into two distinct layers: a main display showing unsecure content and an augmented reality overlay showing secure content. This segmentation allows each layer to have different visibility characteristics - the main display remains fully visible while the secure content overlay is only visible through the AR glasses, providing reliable security protection without compromising overall display functionality.
Solution Approach 2:
The patent creates a virtual copy of secure content that is projected into the user's visual field through the AR glasses. This virtual copy exists in augmented reality space rather than on the physical display, allowing the secure content to be reproduced in a protected environment that is invisible to third parties while maintaining full visibility and interactivity for the authorized user.
3Object-affected harmful factors
If a privacy filter is applied to the display, then viewing angle is restricted, but the display appearance becomes dimmer and less vibrant
Solution Approach 1:
The patent uses augmented reality glasses as an intermediary to deliver secure content directly to the user's eyes without applying any physical filter to the main display. This approach preserves the full brightness and vibrancy of the main display while the AR glasses provide selective visibility for secure content, eliminating the need for dimming or filtering the main display output.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures secure content is only viewed by the intended user, enhancing privacy and compliance with security regulations by automatically adapting to security contexts, with minimal impact on user interaction.

Data Source
AI summary
An information handling system presents unsecure content at a display and secure content at privacy glasses worn by an end user overlapping the location where the secure content would be presented if a secure context allowed presentation at the display. A mouse cursor presented at the display supports interaction with both the unsecure content and the secure content through presentation at the display. The mouse cursor at the display is controllable by touch detections surfaces in the privacy glasses frame. Typed content is presented at the display when it inputs unsecure content and at the privacy glasses when it inputs secure content.
