Abstract: Disclosed are a system, method, device, and/or non-transitory computer readable medium for providing an instant messaging service implemented with a computer. The method includes receiving a request on establishing a conversation interface with an official account registered at the instant messaging service from a client, providing a rich menu user interface associated with the official account on a portion of the conversation interface when the client establishes the conversation interface in response to the request, receiving a selection on a display item included in the rich menu from the client, identifying content associated with the selected display item by a manager of the official account, and providing the identified content to the client through the conversation interface.

Abstract: A contents navigation method includes: sensing a touch; generating sensing information based on the sensed touch; and determining, by using the sensing information, whether the sensed touch is a continuous movement, by sensing an electrical sensor, or a pressing, by sensing a mechanical button. If it is determined that the sensed touch is a continuous movement, a menu display is rotated according to the continuous movement of the electrical sensor based on the sensing information. If it is determined that the sensed touch is a pressing, the menu display is rotated according to the pressing of the mechanical button. A contents navigation apparatus includes: a graphic user interface (GUI) part to generate the menu display; an input sensing part to sense a touch and to generate sensing information based on the sensed touch; and a control part to control the GUI part.
