The wearable device can measure the wearer's stress accurately via Electrodermal activity (EDA). The goal of this device is to turn user's negative affect (e.g., stress, fear, etc.) into something positive (e.g., relaxed, peaceful) by providing positive feedback visually to the user, using Typography, Color and Layout. 

 

The new stress-sensing wearable device as shown in the sketches take the form of a pendant.
