Abstract: A robot cleaner includes a rolling cleaning module including a rolling member configured to rotate clockwise or counterclockwise when viewed from a left side while in contact with a floor, a sensor unit, and a controller. The controller is configured to determine a change in position of the robot cleaner and a change in load current of a motor connected to the rolling member based on data detected by the sensor unit, and determine that a specific area of the floor is a contaminated area when there is a change in the position and a change in the load current.

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.
