Abstract

Navigation system providing route-guidance and traffic information is one of the most widely used driver-support system these days. Most of the navigation system is based on the 2D map paradigm so the information is ed and encoded from the real world. As a result it imposes a cognitive burden to the driver to interpret and translate the ed information to real world information. As a new concept of navigation system, augmented-reality navigation system (AR navigation) is suggested recently. It provides navigational guidance by imposing graphical information on real image captured by camera mounted on a vehicle in real-time. The ultimate goal of navigation system is to assist the driving task with least driving workload whether it is based on the abstracted graphic paradigm or realistic image paradigm. In this paper, we describe the comparative studies on how map navigation and AR navigation affect for driving tasks by experimental research. From the result of this research we obtained a basic knowledge about the two paradigms of navigation systems. On the basis of this knowledge, we are going to find the optimal design of navigation system supporting driving task most effectively, by analyzing characteristics of driving tasks and navigational information from the human-vehicle interface point of view.

자동차 내비게이션 시스템은 경로탐색 및 길안내 등의 기능을 제공하는 대표적인 운전자 지원 시스템의 하나로서 그 사용성이 크게 증가하고 있다. 대부분의 자동차 내비게이션 시스템은 2차원 지도에 기반하고 있는데 이는 기본적으로 지도가 지니는 함축화된 정보 표현 패러다임에 기반하고 있음으로 인해 실세계 정보로의 변환에 인지적 부담이 작용하게 된다. 최근에 개념적으로 대두되고 있는 새로운 내비게이션의 형태는 자동차에 장착된 카메라로부터 실시간으로 취득되거나 자동차 전면 유리창에 투영되는 실제 영상위에 내비게이션 정보를 그래픽으로 표현하는 증강현실의 모습을 취하고 있다. 차량 내에서의 정보 제공 장치로서 내비게이션 시스템은 그것이 함축화된 그래픽이든 아니면 실사 영상이든 궁극적으로 운전자의 운전부하를 줄이고 빠른 직관력을 제공함으로써 주의분산을 최소화 시킴이 중요하다 할 수 있다. 본 논문에서는 증강현실 내비게이션 시스템인 RACE(Reality-Augmented Car-navigation Environment)를 설계 및 구현하고 그것이 실제적으로 운전자의 운전 수행과 인지 및 주의 분산에 어떠한 영향을 미치는지, 그리고 증강현실 내비게이션이 기존의 2차원 지도 기반 내비게이션에 비해 갖는 효용성이 무엇인지에 대하여 운전자 행동에 기반한 인지심리학적 실험을 통하여 분석한다. 이러한 작업들을 바탕으로 정보처리 관점에서 운전자의 운전 수행과 인지적 수행을 위한 최적의 내비게이션 정보 제공 방법은 무엇인지 고찰해본다.
