Description

차량 인터랙션 시스템{Interaction System for Vehicles}Interaction System for Vehicles

본 발명은 탑승자의 제스쳐를 인식하여 시각 또는 청각적이지 않은 방식으로 피드백을 함으로써 운전자의 시야나 신경이 분산되지 않도록 하는 차량 내 인터랙션 시스템에 관한 것이다.The present invention relates to an in-vehicle interaction system that recognizes a driver's gesture and provides feedback in a non-visual or audible manner so that the driver's vision or nerves are not dispersed.

차량 내 인터랙션 시스템에서 피드백은 시각적인 디스플레이나 조명, 또는 청각적인 소리가 대부분을 차지한다.In in-vehicle interaction systems, feedback is most likely a visual display, lighting, or audible sound.

가령 운전자는 내비게이션의 터치 디스플레이부(11)를 조작하고, 이에 대해 내비게이션 시스템은 화면을 변경시키거나 소리를 내는 방식으로 운전자에게 운전자의 입력이 제대로 입력되었음을 피드백한다.For example, the driver manipulates the touch display unit 11 of the navigation device, and the navigation system feeds back to the driver that the driver's input is properly input by changing the screen or making a sound.

그러나 이러한 과정에서 운전자의 시각적 집중력이 디스플레이에 분산되고 청각적 집중력이 피드백 소리에 분산되기 때문에, 차량 내 인터랙션 시스템 조작과정에서 실제 많은 사고가 발생한다.However, in this process, since the driver's visual concentration is distributed on the display and the auditory concentration is distributed on the feedback sound, many accidents occur in the process of operating the in-vehicle interaction system.

이에 카메라(12) 등을 사용하여 촬영되는 탑승자의 제스쳐를 인지하는 방식을 사용한다면 디스플레이 조작으로 인한 시야의 분산은 어느 정도 피할 수가 있겠지만, 여전히 기존의 시각적 내지 청각적 방식으로 피드백을 한다면 사고 위험을 낮추는 데에 한계가 있다.If you use the camera 12 to recognize the gesture of the occupant to shoot the dispersion of the view due to the display operation can be avoided to some extent, but if you still give feedback in the conventional visual or auditory way to avoid the risk of accidents There is a limit to lowering.

한편 종래에는 안마시트가 있었지만 이는 별도의 스위치를 통해 작동되는 수동 방식이었을 뿐 운전자의 제스쳐에 직접적으로 반응하는 자동 방식이 아니었다.On the other hand, there was a massage seat in the past, but it was a manual method operated through a separate switch, but not an automatic method directly responding to a gesture of a driver.

이에 본 발명은 운전자의 시선이나 청각적 주의력 분산 없이 안전운행을 하면서 정확한 피드백을 제공할 수 있는 차량 인터랙션 시스템을 제공함을 목적으로 한다. Accordingly, an object of the present invention is to provide a vehicle interaction system capable of providing accurate feedback while driving safely without distracting the driver's gaze or auditory attention.

또한 본 발명은 안마 시트 등과 연계해서, 피드백 과정을 재미있고 안락하게 구성할 수 있는 인터랙션 시스템을 제공함을 목적으로 한다.In addition, an object of the present invention is to provide an interaction system that can be configured in a fun and comfortable manner in conjunction with a massage seat and the like.
