Abstract: Systems and methods for training network-connected objects to provide configurations in association with events within media assets. A respective configuration setting of a network-connected object and a baseline biometric state of a user may be stored in a database for each event within a media asset. An event within a media asset (for display) may be detected. In response, a command may be sent to the network-connected object to implement the respective configuration setting. A determination may be made whether the user adjusts the respective configuration setting to a new configuration setting within a predefined time of the event. A biometric state of the user may be retrieved from a biometric device in response to the adjustment to a new configuration setting. If the biometric state does not correspond to the baseline biometric state, the respective configuration setting may be replaced with the new configuration setting.
