摘要
获取学习状态数据是实现智能教育的前提,生理参数是反映学生学习状态的重要信息。而目前在智能教育领域生理参数检测方法比较单一,仍然以接触式为主,存在一定局限性。而非接触式生理参数检测方法更有利于智能教育的广泛推广。分析了基于视频的非接触式生理参数检测方法。介绍了成像式光电容积描记技术的原理,对其发展及现状进行了归纳分析,总结了近些年生理参数检测在教育领域的相关应用。对基于视频的非接触式生理参数检测在教育领域的发展趋势进行了总结与展望。
Acquisition of learning status data is the premise of intelligent education,and physiological parameters are important information to reflect students’learning status.However,in the field of intelligent education,the detection method of physiological parameters is relatively single,still mainly in contact,and has some limitations.The non-contact physiological parameter detection method is more conducive to the wide spread of intelligent education.The non-contact physiological parameter detection method based on video is analyzed.Firstly,the principle of the imaging photoelectric volume tracing technology is introduced,then its development and current situation are summarized and analyzed,and the relevant applications of physiological parameter detection in the field of education in recent years are summarized.Finally,the development trend of video-based non-contact physiological parameter detection in the field of education is summarized and prospected.
