Abstract: A computer-implemented method for sharing user activity information comprises: receiving a user action history generated in one service among a first service and a second service through an application executed in an electronic device; mapping and storing account information at the first service, account information at the second service, and the user action history with respect to a user of the electronic device; and transmitting, to the application, information on the user action history or an event corresponding to the user action history, such that the event corresponding to the user action history is provided to the user through another service among the first service and the second service.

Abstract: An application producing method regarding a first and second application, the method includes receiving an application generation request related to a second application, the second application being subordinate to a first application, generating the second application and computer readable instructions related to a switch interface for selecting at least one of the first and second applications, the switch interface computer readable instructions related to the switch interface, which when executed by at least one application executing apparatus, causes the application executing apparatus to display the switch interface on at least one of the first and second applications, and when the switch interface is in a first state, the first application is controlled based on a first user input received by the at least one application executing apparatus, and when the switch interface is in a second state, the second application is controlled based on the first user input.

Abstract: An over-the-ear type headset having a hanger capable of being selectively bent and positioned to afford easy and comfortable wearing regardless of a size and a shape of the ear, and an end-cap having a bulging portion adapted to rest on a recess region below a user's ear to assure stable support of the headset is disclosed. The headset includes a headset body containing an earphone and a microphone, and a hanger coupled to the headset body, which is adapted to be bent along a back of a user's ear.
