TECHNICAL FIELD [0001] The present invention relates to a method of controlling information output of a wearable device,

The present invention relates to a method of outputting information by dividing a wearable device worn by a plurality of passengers in a vehicle and a vehicle capable of performing the method.

In the conventional vehicle, sound control is performed according to the positions of the front and rear speakers. For example, when navigation guidance voice reproduction is required during media reproduction, in order to more accurately output the guidance voice, the driver lowers the volume of the media playback sound of all the seats and outputs the sound by increasing the volume of the navigation guidance voice. At this time, since the rearrangement is not relevant to the driver, the reproduction is performed without reducing the volume of the media playback sound.

Since such a conventional vehicle sound control system is designed without considering wearable devices worn individually by passengers, it is necessary to restrict the media playback sound for the passenger according to the situation of the vehicle guide and the warning light, and to allow all passengers to listen to the same sound compulsorily There is a problem.

That is, in the conventional vehicle, it is necessary for the passenger to forcibly listen to the guidance and warning sound necessary for the driver, and the user can not selectively play different contents (music, movie). Especially, when the driver speaks the mobile phone through the handsfree function, all the passengers hear the conversation through the vehicle speaker.

In particular, in terms of video, the AVN (Audio, Video, Navigation) system of a vehicle is prohibited from being operated to disperse the video screen or other attention during driving in order to prevent dispersion of the driver's attention during driving. In such an environment, the video screen or other operations are restricted even when the passenger is not the driver, and the passengers are forced to listen to the guidance voice during the video viewing or other voice related to driving.

In addition, in general, a hindquarter monitor requires an additional purchase at the time of purchasing a vehicle, so the purchase of the monitor becomes hesitant due to the additional amount.

The present invention provides a vehicle and a control method thereof that can output information and contents necessary for each occupant through a wearable device.
