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

1.研究目的一个易于使用的人机界面是必不可少的，以提高ITS技术广泛接受的车辆用户。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。除此之外，我们使用车载信息系统来评估这些技术的有效性，然后提出车载设备的下一个计划。研究结果1）驾驶员状态的检测技术（1）驾驶员困倦的检测我们开发了使用图像处理技术通过眨眼持续时间估计唤醒水平的方法。(2)疏忽驾驶的检测提出了一种实用的眼睛注视方向的测量方法。(3)驾驶时对移动的手机的注意力的检测开发了从眼球运动的范围和速度检测注意力水平的方法。2）提供车辆信息的技术（1）容易看到的显示根据驾驶员的视力和观看距离，改进了老年驾驶员容易看到的方法。(2)提出了综合考虑驾驶紧急情况和驾驶员唤醒水平的报警方法。(3)可识别显示根据空间感知能力的差异，开发出了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.
