EEG Power Analysis Data from Holographic Display Study in Museums

This dataset contains the spectral power values derived from EEG recordings collected during the experiment. It includes cleaned data from 24 participants across three display conditions (hologram, photograph, and 3D-printed model). Outliers were manually identified and removed using a ±3 standard deviation threshold to ensure the accuracy of the results. The dataset was used for the statistical comparisons reported in the manuscript.本数据集包含实验过程中采集的脑电图（EEG）记录所提取的频谱功率值。其涵盖24名参与者在三种显示条件：全息图、照片与3D打印模型下的经清洗后数据。研究人员采用±3倍标准差阈值手动识别并剔除异常值，以保障结果的准确性。本数据集已用于该论文中报道的统计对比分析。
