Prototype word processor operable by ocular movement.

1)制作了一种简单廉价的手动“对话装置”和两种计算机辅助的“对话装置”并进行了测试。这些设备只能在合作伙伴的帮助下通过眼球运动进行操作。这些都是非常有用的2)50个日语音(片假名音节)的系统表的大小是27厘米乘18厘米，每一帧的大小是3厘米乘3厘米。3)将桌子放在受试者面前，受试者的头部借助一种钻头固定。4)通过桌子上的洞或放在不太熟练的眼睛前面的小镜子来观察瞳孔的移动方向(这是指视觉移动的方向)。5)桌子被分成6个区域，每个区域由3个字母组成。首先，受试者被命令观察所选角色所在的区域。然后，操作员展示了区域，受试者最终通过开始指示字母。同样的程序也在计算机上进行。在这种情况下，字母显示在显示器的底线上。这样就可以构成一个句子。7)另一个句子的原理如下。光标固定在监视器的中心，并且操作员沿与对象眼睛的移动相反的方向移动50个日语声音的整个系统表。8)另一种检测目标字母位置的方法是利用“二维位置测量装置”测量被摄体的视觉位置、眼电绝对值、瞳孔闭合等。9)因此，除了上述三种装置外，“视觉操作文字处理器”的实现是有希望的。

1) One manually operated simple and inexpensive 「Dialogue device」 and two types of computer aided ones were made and tested. These devices can be operated only by ocular movements, with the help of a partner. These are very useful.2) The size of the systematic table of the fifty Japanese sounds (Katakana syllabary) is 27cm by 18cm, and the size of each frame is 3cm by 3cm. The complete design of the table was decided.3) The table was presented in front of a test subject, whose head was fixed with the aid of a kind of bit. The bit was cast from the subject's own teeth.4) The direction of the movement of the pupil (this refers the direction of the movement of sight) was observed through the hole in the table or a small mirror set in front of the less skillful eye.5) The table was divided into 6 areas, each composed of 3 by 3 letters. First, the subject was ordered to watch an area where the chosen character was to be placed. Then, the operator presented the area and the subject eventually indicated the letter by staring.6) The same procedure was performed with a computer. In this case, the letter was presented on the bottom line of the monitor. Thus a sentence can be constructed.7) The principle of another one is as follows. The cursor is fixed in the center of the monitor and the whole systematic table of the fifty Japanese sounds is moved by the operator in the opposite direction to the movement of the eye of the subject. The result was similar to the preceding systems.8) Another way to detect the position of the desired letter is to measure the position of the sight of the subject by the use of a "two-dimensional position-measuring device", the absolute value of the EOG, pupil closure and so on.9) Thus, in addition to the above mentioned three devices, the realization of the 「Sight-Operated Word processor」 is hopeful.
