Abstract: A wearable device is configured to perform stress detection, emotion recognition and emotional management. The wearable device may perform a process that includes monitoring an emotional score of a user, the emotional score computed based on measured biological signals of the user. The device may detect an emotional event from the monitored emotional score. The device may transmit an alert signal to the user in response to the detected emotional event, in which an action plan associates the alert signal with a corresponding action to be performed by the user. The device may evaluate an effectiveness of the action plan by evaluating an impact of the action on the emotional score of the user. The device may determine a change to the action plan based on the evaluated effectiveness of the action plan. Finally, the device may incorporate the determined change into the action plan.
