Information Display Method to Drivers based on Characteristics of Sensory Perception and Recognition

1.研究目的要提高智能交通系统的技术水平，一个易于使用的人机界面是必不可少的。在这些研究中，我们开发了驾驶员状态检测、信息显示、个体差异自适应技术等基础技术。此外，我们使用车载信息系统评估了这些技术的有效性，然后提出了车载设备的下一步计划。研究结果1)驾驶员状态检测技术(1)驾驶员昏昏欲睡的检测利用图像处理技术，提出了通过眨眼时长估计唤醒程度的方法。(2)疏忽驾驶的检测。提出了实时测量眼睛注视方向的方法。(3)驾驶时对手机的注意力检测。我们提出了从眼睛运动的范围和速度来检测浓度水平的方法。2)提供车辆信息的技术(1)易于看到的显示。我们改进了基于驾驶员视觉敏锐度的容易看到的方法(2)紧急情况下的警示我们提出了考虑驾驶紧急情况和驾驶员唤醒程度的警示方法。(3)可识别显示器我们开发了基于空间感知能力差异的女性容易识别的路线引导方法。下一步计划是改进区分个人和适应每个用户的技术。

1. Research PurposeAn easy-to-use human interface is indispensable to improve the ITS technology widely accepted by vehicle user. In these researches, we develop fundamental technologies such as driver's status detection, information display, adaptive technique to individual differences. Beside that, we evaluate an effectiveness of these technologies using an in-vehicle information system, and then present a next plan for in-vehicle devices.2. Research Results1) Technology for detecting driver's status(1) Detection of driver's drowsinessWe've development the method for estimating an arousal level by blink duration using image-processing technology.(2) Detection of inattentive drivingWe have presented the method of measuring an eye gaze direction in practical time.(3) Detection of concentration to mobile phone while drivingWe have developed method of detecting a concentration level from the range and speed in eye movement.2) Technology for offering vehicle information(1) Easy-to-see displayWe have improved the method for elderly driver to see easily based on driver's visual acuity and viewing distance.(2) Warning in emergencyWe've presented the warning method of considering driving emergency and driver's arousal level.(3) Recognizable displayWe have developed the route guidance method for women to recognize easily based on differences in space perception ability.The next plan is to improve technologies for discriminating individuals and adapting to each user.
