selecting a color corresponding to the emotion information of the user; and

displaying the notification information for the at least one event by using the selected color.

9. The method of claim 1 , further comprising providing a response to an utterance of the user related to the at least one event, based on the determined interaction type.

10. The method of claim 1 , wherein the providing of the notification information for the at least one event comprises:

identify, from the voice data, the at least one event related to the schedule and an emotional state of the user for the at least one event related to the schedule by analyzing the response to the query;

learn emotion information of the user for the at least one event related to the schedule, based on the emotional state of the user for the at least one event related to the schedule;

determine an interaction type for the at least one event related to the schedule, based on the emotion information of the user for the at least one event related to the schedule; and

provide notification information for the at least one event related to the schedule through the virtual assistant interface, based on the interaction type.

13. The electronic device of claim 12 , wherein the at least one processor is further configured to:

extract information related to the at least one event from the voice data; and

register the at least one event as a new event in the electronic device, using the extracted information.

14. The electronic device of claim 12 , wherein the at least one processor is further configured to:

obtain default emotion information related to the at least one event from information for mapping events to emotion information; and

learn the emotion information of the user for the at least one event by modifying the default emotion information, based on the emotional state of the user for the at least one event related to the schedule.
