Abstract: The present invention relates to a mobile device, a method of implementing a virtual reality (VR) device controller using the mobile device, and a VR display system. According to one embodiment of the present invention, a method driving a virtual reality device (VR device) controller includes the steps of executing a VR application (VR app) for driving a VR device, driving a controller connection processor interlocked with the VR app, selecting either an external controller or a virtual controller as a controller for driving the VR device via the controller connection processor, and if the virtual controller is selected, performing communication with the VR device by generating a data packet corresponding to the selected virtual controller. According to the embodiment of the present invention, since a mobile device is able to provide a virtual controller for driving a VR device, a user is able to more conveniently utilize the VR device.

Abstract: An electronic device is disclosed. The electronic device according to the present invention comprises: a housing elongated to be long; a tip coupled to one end of the housing; a motion sensor located at at least one side of the housing; and a control unit for operating in a first mode of recording, in a memory, content corresponding to a motion of the tip or the housing on the basis of a user's operation acquired through the motion sensor and/or a second mode of performing a specific function on the basis of a user's operation, wherein mode switching between the first mode and the second mode is performed when the user's operation acquired through the motion sensor corresponds to a preset operation.
