A computer server system comprises a communications module; a processor coupled with the communications module; and a memory coupled to the processor and storing processor-executable instructions which, when executed by the processor, configure the processor to receive, via the communications module and from one or more devices, a signal including biometric data of a user; analyze the biometric data to predict an emotional state of the user; determine that the predicted emotional state of the user satisfies predefined criteria; and responsive to determining that the predicted emotional state of the user satisfies the predefined criteria, send via the communications module to the one or more devices a signal including one or more incentives based on the predicted emotional state.
