Abstract

<p>This research aims to reduce stress of passengers who get on autonomous vehicles. We developed an Augmented Reality (AR) display system on an experimental vehicle, which aims to reduce stress caused by two kinds of invisible factor. One is visual information of invisible region such as out of sight occluded by the vehicle. The other is instrument information to automatically control the vehicle. Our proposed system visualizes the occluded road surface by seeing-through the interior and exterior of the vehicle. Moreover, computer graphics model of the vehicle trail are overlaid on the displayed image using AR technique so that the passengers can easily confirm the auto driving control is working correctly. The displayed images enable passengers to comprehend the road condition and the expected vehicle route in occluded region. In order to confirm the effectiveness of our proposed method, we develop a prototype display system on a vehicle and investigate mental stress using instruments to measure physiological indices such as heart rate variability, sweat information and Electroencephalogram.</p>
