Abstract: A wearable device and a vehicle capable of precisely measuring physical activities only in the case the physical activities are a target of exercise by excluding additional physical activities generated by driving a vehicle from the target of exercise to be measured when a user drives the vehicle while wearing a wearable device and the physical activities are measured. A method of controlling the wearable device includes obtaining movement information of a user, excluding the movement information of the user obtained while the user is driving the vehicle from recording or displaying the movement information of the user when it is checked through the movement information of the user that the user is driving a vehicle, and continuing to measure the movement information of the user and resuming the recording and displaying of the movement information of the user when it is determined that the user finishes driving the vehicle.

Abstract: A control knob device that may be used in a vehicle to control audio volume or the like includes a shaft connected with a knob cap, an elastic member pressed by the shaft to be elastically deformed, and a switch located adjacent to the elastic member. The switch includes a switch part configured to output a signal upon a deformation of the elastic member. A deformable member deformed by a load greater than that when the elastic member is deformed and the switch outputs the signal, is configured to change a relative position between the knob cap and the shaft.
