Smart Mask Facial-Movement Display for Visible Expressions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Face masks often interfere with person-to-person communication by hiding significant portions of the face, limiting the ability to interpret facial expressions and reducing the breadth of communication.
Innovation Solution
Smart masks equipped with sensors that detect facial movements and audio, coupled with a control module, display real-time images of the wearer's face, including mouth and emotional expressions, using displays integrated into or overlaid on the mask.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If face masks are worn to prevent infection spread, then health protection is improved, but facial expression visibility deteriorates
Solution Approach 1:
The patent creates a digital copy of the wearer's facial expressions and projects it onto the mask surface. Sensors detect actual facial movements, and a display system reproduces these expressions visually on the mask, allowing observers to see facial expressions even when the mask covers the face.
Solution Approach 2:
The patent introduces an intermediary system consisting of sensors, processors, and display elements that mediate between the wearer's actual facial expressions and the observer's perception. This intermediary system captures, processes, and transmits facial expression information through the mask barrier.
2Reliability
If masks cover the face to reduce infection risk, then disease transmission prevention is improved, but communication effectiveness deteriorates
Solution Approach 1:
The system creates visual copies of facial expressions on the mask surface, enabling non-verbal communication to continue effectively even when the mask physically blocks the face. This maintains communication ease while preserving infection prevention benefits.
3Ease of operation
If displays are integrated into masks to show facial expressions, then communication effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions into the mask system: infection filtration, facial expression detection, image processing, and visual display. This multi-functionality approach consolidates what could be separate complex systems into a single integrated wearable device.
Solution Approach 2:
The patent uses flexible display elements and thin-film sensors that can be integrated into the mask structure without adding significant bulk or rigidity. This maintains wearability while enabling complex functionality.

AI summary
A smart mask includes a first material layer, at least one display, a first sensor, and a control module. The first material layer is configured to cover a portion of a face of a person. The at least one display is connected to the first material layer and configured to display images over a mouth of the person. The first sensor is configured to detect movement of the mouth of the person and generate a signal indicative of the movement of the mouth. The control module is configured to receive the signal and display the images on the display based on the movement of the mouth.
