本研究旨在探讨扫描屏幕键盘对于严重运动障碍人士的有效性。为了增强打字性能，屏幕键盘采用了分组行列扫描和使用频率布局。除了国际字母布局外，屏幕键盘还为中国用户提供了两种中文选择布局。通过模拟和实验进行可用性评估。进行可用性评估是为了将其性能与 Microsoft Windows XP 中内置的块扫描的 QWERTY 布局的性能进行比较。结果表明，使用扫描屏幕键盘的性能优于使用Windows XP。两种不同键盘的错误率之间没有发现显着差异。
This study aims to explore the effectiveness of a scanning on-screen keyboard for persons with severe motor disabilities. In order to enhance the typing performance, the on-screen keyboard employs the group-row-column scanning and a frequency-of-use layout. Besides the international alphabetical layout, the on-screen keyboard also provides two Chinese selection layouts for Chinese users. The usability evaluation was carried out with simulations and experiments. The usability evaluation was conducted to compare the performance with that of the QWERTY layout of block scanning built in Microsoft Windows XP. The results demonstrated that the performance of using the scanning on-screen keyboard was better than that of using the Windows XP. No significant difference between the error rates of the two different keyboards was found.
