This paper describes our experiences in building a virtual keyboard implemented using a Brain-Computer Interface (BCI) that interacts with the eMotiv EPOC Neural Headset. The contribution of the work is an alternative input device for those who have a motor disability and are challenged by traditional input devices. The advantages of a virtual keyboard based on BCI are summarized and we describe its design and implementation. We also present the results of a preliminary study that has suggested several improvements for enhancing the effectiveness of the virtual keyboard.
