The development of a novel computer writing system based on eye movements is introduced herein. A system of these characteristics requires the consideration of three subsystems: (1) A hardware device for the acquisition and transmission of the signals generated by eye movement to the computer; (2) A software application that allows, among other functions, data processing in order to minimize noise and classify signals; and (3) A graphical interface that allows the user to write text easily on the computer screen using eye movements only. This work analyzes these three subsystems and proposes innovative and low cost solutions for each one of them. This computer writing system was tested with 20 users and its efficiency was compared to a traditional virtual keyboard. The results have shown an important reduction in the time spent on writing, which can be very useful, especially for people with severe motor disorders.
本文介绍了一种基于眼球运动的新型计算机书写系统的开发。具有这些特性的系统需要考虑三个子系统：（1）一种硬件设备，用于采集眼球运动产生的信号并将其传输到计算机；（2）一种软件应用程序，除其他功能外，还允许进行数据处理以最小化噪声并对信号进行分类；（3）一种图形界面，允许用户仅使用眼球运动在计算机屏幕上轻松书写文本。这项工作分析了这三个子系统，并为每个子系统提出了创新且低成本的解决方案。该计算机书写系统对20名用户进行了测试，并将其效率与传统虚拟键盘进行了比较。结果表明，书写时间显著减少，这可能非常有用，特别是对于患有严重运动障碍的人。
