Devices, computer-readable media and methods for affecting mental states of a first user and a second user are disclosed. For example, a processor may receive first biometric data for a first user, quantify a mental state of the first user based upon the first biometric data, receive second biometric data for a second user, and quantify a mental state of the second user based upon the second biometric data. The processor may further select a first automated action to affect the mental state of the first user and the mental state of the second user, and implement the first automated action to affect the mental state of the first user and the mental state of the second user.
