EEG dataset: Engineers' brain activity when CAD modelling from isometric and orthographic projections

The database contains raw and clean EEG data of 20 engineers, captured while they were performing visuospatially-intensive design tasks of CAD modelling based on the technical drawings with orthographic and isometric projections.本数据库包含20名工程师的原始及经预处理的纯净脑电图（Electroencephalogram, EEG）数据，该类数据采集自受试者执行基于带有正投影与等轴测投影的工程图纸进行CAD建模的视觉空间密集型设计任务期间。
