    • PROBLEM TO BE SOLVED: To provide a computer input method having an operability close to a pointing device by manual operation such as a mouse so that operation of a computer can be easily performed even by a hand- or leg-handicapped person or even in the case that manual operation cannot be performed. SOLUTION: In this method, a camera 10 capable of taking moving pictures and a computer 2 storing images taken by the camera 10 in a predetermined period are provided, and image information of a person's face caught by the camera 10 is scanned while comparing with a template 16 fitted to the range of the size of the iris 18 of the eye 15. The gray scales of images of the iris 18 part of the eye 15 and the other part of the face are detected to determine the position of the eye 15, and the area of the iris 18 in the position of the eye 15 is determined. The open/close state of the eye 15 is determined from the determined iris area, whereby a predetermined processing input to the computer 2 is performed. COPYRIGHT: (C)2006,JPO&NCIPI
    • 要解决的问题:为了提供一种具有靠近指向装置的可操作性的计算机输入方法,通过诸如鼠标的手动操作,使得即使由手或者残疾人也可以容易地进行计算机的操作,或者 即使在不能进行手动操作的情况下也是如此。 解决方案:在该方法中,提供能够拍摄运动图像的照相机10和存储由相机10拍摄的图像在预定时间段内拍摄的图像的计算机2,并且扫描由相机10捕获的人脸的图像信息,同时扫描 与安装在眼睛15的虹膜18的尺寸范围上的模板16进行比较。检测眼睛15的虹膜18部分和面部的另一部分的图像的灰度级,以确定眼睛的位置 眼睛15,并且确定眼睛15的位置处的虹膜18的区域。 从确定的虹膜区域确定眼睛15的打开/关闭状态,由此执行到计算机2的预定处理输入。 版权所有(C)2006,JPO&NCIPI

    • A doze detection method, which accurately detects a blink burst and improves speed and accuracy of doze detection, includes measuring a state where the eye is substantially open as an open eye time and another state as a closed eye time, defining a time shorter than an average blink interval of a healthy adult in an alert state as a first threshold time; defining a time longer than an average closed eye time of a healthy adult in an alert state as a second threshold time; and defining blinks as a blink burst when detecting an eye opening equal to or shorter than the first threshold time. A doze state is determined when the closed eye time of a blink among the blinks during the blink burst reaches at least the second threshold time, the blink occurring after an open eye time equal to at most the first threshold time.
    • 准确地检测眨眼脉冲并提高打盹检测的速度和准确度的瞌睡检测方法包括测量眼睛基本上作为睁眼时间的状态和作为闭眼时间的另一状态的时间,该时间短于 处于警戒状态的健康成年人的平均眨眼间隔作为第一阈值时间; 将处于警戒状态的健康成年人的平均闭眼时间定义为比第二阈值时间长的时间; 以及当检测到等于或小于所述第一阈值时间的眼睛开口时,将闪烁定义为闪烁突发。 当在闪烁突发期间闪烁之间的闪烁的闭合眼睛时间达到至少第二阈值时间时,确定打盹状态,在睁眼时间等于至多第一阈值时间之后发生闪烁。
