Study on safety education to elderly person during walking down a stair.

要求老年人在实际条件下带着眼摄像系统走下楼梯。本次实验选用JR站的楼梯，因为JR站是人们常用的公共设施之一。并建议学生作为研究对象与老年人进行比较。得到了以下结果：1)老年人楼梯的清醒速度为0.55(]SY.+- - [)0.09m/s，学生为0.68(]SY.+- - [)0.05m/s。2)老年人眼动模式的长度和面积较小。3)老年人的注视时间明显长于学生。在某些情况下，眼摄像系统不得不调整位置。然而，这种眼相机系统在研究眼运动的感知和本质方面有许多优点。模拟投影屏幕也用于实验室实验，但在实际条件下的研究对于了解老年人的特征更有价值。

The elderly persons were requested to walk down a stair with eye-camera system in an actual condition. The stair of JR station was used for this experiment because of the JR station is one of the public facilities commonly well used by many people.The students were also suggested as the subject to compare the datum with the elderly persons. The following results were obtained.1)The waking speed of sown stair in elderly person was 0.55(]SY.+-。[)0.09m/s and in student was 0.68(]SY.+-。[)0.05m/s.2)In elderly person, small length and area of eye movement pattern was produced.3)The eye fixing time in elderly person was longer then in the students.4)In some cases, the eye-camera system had to trim the position.Nevertheless, this eye-camera system has many merits of studying the perception and nature of eye movement.The simulated projected screen was also used for the experiment in laboratory but the study in an actual condition has a more merit to study for understanding the characteristics of elderly person.
