Abstract

The present teaching relates to a protector capable of dynamically deploying protection to a user. Data is received from multiple sensors embedded in the protector, worn by a user on head and providing protection to the user when needed. Distances between the user and others appearing nearby detected based on the data are dynamically tracked. If the protector is in a protection state, the protection is retracted when the tracked distances satisfy a first condition. The state of the protector is reset to a no-protection state. If the protector is in a no-protection state, the protector applies the protection to the user, when a second condition is satisfied based on the tracked distances, by releasing one or more protection shields from the protector to create a barrier between the user and others and the state of the protector is reset to a protection state.
