Abstract: According to one aspect of the present invention, there is provided a method for providing a user interface, comprising the steps of: (a) acquiring information on postures or motions of a first device and a second device, and sensing an input event specified on the basis of a relative relationship between the posture or motion of the first device and that of the second device; and (b) in response to the occurrence of the input event, causing at least some of contents and functions provided on the first device to be provided on the second device, or causing at least some of contents and functions provided on the second device to be provided on the first device.

Abstract: According to one aspect of the present invention, there is provided a method for providing a user interface. The method comprises acquiring information on a position where at least one of a first device and a second device contacts a body of a user, and upon the occurrence of a triggering event that causes haptic feedback in at least one of the first device and the second device, controlling properties of haptic feedback provided in at least one of the first device and the second device, with reference to the acquired information on the body contact position, information on a display state associated with the triggering event, and information on contents or functions associated with the triggering event.

Abstract: According to one aspect of the present invention, there is provided a method for providing a user interface. The method includes when an input event occurs, acquiring information on postures or motions of a first device and a second device associated with the input event in a preset time interval including the time of occurrence of the input event, and determining a command to be carried out in response to the input event with reference to a relative relationship between the posture or motion of the first device and that of the second device.

Abstract: The present invention relates to a method for matching multiple devices, and a device and a server system for enabling the matching thereof. According to one aspect of the invention, provided is a matching method comprising the steps of: determining, from a perspective of a first device, characteristic information on a biological state of a user, and independently determining, from a perspective of a second device, characteristic information associated with or generated according to the biological state of the user; and matching the first device and the second device on the basis of the characteristic information determined from the perspective of the first device and the characteristic information determined from the perspective of the second device.

Abstract: The present invention relates to a method for matching multiple devices, and a device and a server system for enabling the matching thereof. According to one aspect of the invention, provided is a matching method comprising: determining, from a perspective of a first device, characteristic information on a motion of the first device; determining, from a perspective of a second device, characteristic information on at least one of the motion of the first device, an input to the second device according to the motion of the first device, an operation on the second device according to the motion of the first device, and a location change of the first device caused by the motion of the first device; and matching the first device and the second device based on the characteristic information determined from the perspective of the first device and the characteristic information determined from the perspective of the second device.
