Abstract

A "virtual keyboard" (VK) is a letter spelling device operated for example by spontaneous electroencephalogram (EEG), whereby the EEG is modulated by mental hand and leg motor imagery. We report on three able-bodied subjects, operating the VK. The ability in the use of the VK varies between 0.85 and 0.5 letters/min in error-free writing.

摘要

“虚拟键盘”（VK）是一种例如通过自发脑电图（EEG）操作的字母拼写设备，其中脑电图由手部和腿部的心理运动想象进行调制。我们报告了三名身体健全的受试者操作虚拟键盘的情况。在无错误书写中，使用虚拟键盘的能力在每分钟0.85至0.5个字母之间变化。
