Face mask for accurate location of sensors relative to a users face, a communication enabling face mask and a communication system including the face mask

Abstract

Face mask communication systemincludes face maskworn by userand signal receiving hand gloveworn by user. Gloveincludes data receiverfor data communication with maskand includes multiple vibrotactile devices for generating haptic signals. Maskincludes an elastic element of flexible material, and a plurality of EMG sensorsfixed to the element, for sensing electrical activity of face regions of the user'sface. Maskincludes a processor; decoding algorithmand transmitterfor, respectively, processing signals from the sensors; generating command instructions based on the signals; and wirelessly transmitting the signals to receiverof glove. Maskincludes thread elements connected to the elastic element of maskenabling tensioning of the element to provide for fitment of maskto users of different sizes, for optimal location sensors
