The prototype suggests an alternative to detect facial expressions while wearing a facemask and proposes a wearable device that produces a visual representation of the covered expressions to help people communicate easier. The prototype uses muscle sensors were used to distinguish facial expressions, e.g., sadness, happiness, and anger.
The readings are then translated into visual outputs displayed with light in front of the facemask. This system creates a new visual language that is intuitively understandable to replace non-verbal communication.
