This paper describes a multimodal interface that combines a Brain-Computer Interface (BCI) with an electrooculography (EOG) interface. The non-invasive spontaneous BCI registers the electrical brain activity through surface electrodes. The EOG interface detects the eye movements through electrodes placed on the face around the eyes. Both kind of signals are registered together and processed to obtain the mental task that the user is thinking and the eye movement performed by the user. Both commands (mental task and eye movement) are combined in order to move a dot in a graphic user interface (GUI). Several experimental tests have been made where the users perform a trajectory to get closer to some targets. To perform the trajectory the user moves the dot in a plane with the EOG interface and using the BCI the dot changes its height.
本文描述了一种多模态接口，它将脑机接口（BCI）与眼电图（EOG）接口相结合。非侵入性自发脑机接口通过表面电极记录脑电活动。眼电图接口通过放置在眼睛周围面部的电极检测眼球运动。这两种信号同时被记录并进行处理，以获取用户正在思考的心理任务以及用户所执行的眼球运动。两种命令（心理任务和眼球运动）相结合，以便在图形用户界面（GUI）中移动一个点。已经进行了几项实验测试，用户在这些测试中执行一条轨迹以接近某些目标。为了执行该轨迹，用户通过眼电图接口在平面上移动点，并且使用脑机接口使点改变其高度。
