Abstract: The present invention relates to a visualized virtual agent configured to provide a visual response to a user, wherein the visualized virtual agent is further configured to provide an artificial physiological color change response to a user on the basis of one or more user-specific parameter, wherein the visualized virtual agent is configured to acquire user-specific data for at least one user-specific parameter using at least one sensor, the one or more user-specific parameter comprising activity data of the user and/or physio-psychological data of the user, and wherein the artificial physiological color change response is provided in response to monitored changes of the acquired user-specific data for the at least one user-specific parameter of the activity data of the user and/or the physio-psychological data of the user, the artificial physiological color change response comprising at least in part a color change of the visualized virtual agent.
