Privacy-Preserving Whiteboard Using AR Geofencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional collaboration tools, including whiteboards, fail to ensure confidentiality and accessibility for authorized users, particularly in shared workspaces, as they do not effectively obscure content from unauthorized individuals and lack features for users with disabilities.
Innovation Solution
A system utilizing privacy-preserving whiteboard devices and AR Headsets that authenticate users, record and store audio and visual content, and provide customizable settings for accessibility, ensuring only authorized users can view and access the content, while accommodating users with disabilities through color adjustments and audio transcription.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional whiteboards are used in shared workspaces, then collaboration is enabled, but confidentiality and privacy of content cannot be ensured
Solution Approach 1:
The patent implements different visibility properties for different spatial locations. The whiteboard content is made visible only to authorized users within a specific geographic boundary, while remaining invisible to unauthorized users outside this boundary. This is achieved through geofencing technology that detects user positions and controls content visibility accordingly, allowing the same physical whiteboard to serve both collaborative and confidential requirements simultaneously.
2Reliability
If content is obscured from unauthorized users, then privacy is preserved, but accessibility for authorized users may be reduced
Solution Approach 1:
The system dynamically adjusts whiteboard visibility based on real-time detection of authorized users within the geofenced area. When authorized users are detected, the whiteboard content becomes visible to them; when no authorized users are present or unauthorized users are detected, the content becomes invisible. This dynamic adaptation ensures privacy is maintained while accessibility is provided to authorized users on demand.
3Adaptability or versatility
If conventional whiteboards are used, then basic collaboration is possible, but accessibility features for users with disabilities are lacking
Solution Approach 1:
The patent integrates multiple accessibility functions into the whiteboard system, including audio output for hearing-impaired users, microphone integration for speech-to-text conversion, and color adjustment capabilities for visually-impaired users. These additional features are built upon the core whiteboard functionality, allowing the same device to serve both traditional collaboration needs and accessibility requirements without requiring separate specialized equipment.

AI summary
Providing a method for secure collaboration amongst professionals so that the contents of a collaborative work session are only seen and accessed by those professionals who are authorized to view the contents. A privacy-preserving whiteboard device, along with a set of Augmented Reality (AR) Headsets that are securely and communicatively connected to the privacy-preserving whiteboard device are used to ensure the confidentiality of the contents of the collaboration session.
