In addition, the processor 130 according to another embodiment may identify at least one of the user's gender, the user's age, or the user's nationality based on the received user image. According to another embodiment, the processor 130 may identify at least one of a user's speech language, a user's gender, a user's age, or a user's nationality based on both the received voice and image.

In addition, when the environmental information of the electronic device 100 is changed, the processor 130 may newly update the identification information of the electronic device 100 based on the changed environmental information of the electronic device 100 and the rule information stored in the memory 140. A new content corresponding to the electronic device 100 can be identified among a plurality of contents by comparing the identification information of the newly acquired electronic device 100 and the identification information of each of the plurality of contents, and the identified contents The display 120 may be controlled to display.

For example, assume that the current time information is changed from 11:59 to 12:01. Based on the predefined criteria, it is assumed that before 12:00 is classified as morning and after 12:00 as lunch. Here, as time information passes 12:00, environment information and identification information of the electronic device 100 corresponding to the environment information may be changed from morning to lunch.
