摘　　要：基于生理数据的自适应学习系统能够识别学习者的情感与认知,对于提升系统的个性化服务能力和学习者的使用体验意义重大。基于此,文章首先提出了基于眼动追踪的自适应学习框架,根据已有的认知风格理论,此框架可分析不同认知风格学习者的眼动模式差异。在此基础上,考虑眼动行为中注视总持续时间和注视点数量,文章构建了基于眼动追踪的在线学习者认知风格识别模型,并通过眼动实验验证了此模型的可行性和有效性,为自适应学习系统的设计与开发提供了新的解决方案。An adaptive learning system based on physiological data could identify learners’emotion and cognition,which is of great significance for improving the system’s personalized service capabilities and learners’user experience.Based on this,the paper firstly proposed an adaptive learning framework based on eye movement tracking.According to the existing cognitive style theories,this framework could analyze the differences in eye movement patterns among learners with different cognitive styles.Accordingly,considering the total duration of fixation and the number of fixation points in eye movement behavior,the pappr constructed an cognitive style recognition model of online learners based on eye movement tracking,and verified the feasibility and effectiveness of this model through eye movement experiments,which could provide a new solution for the design and development of adaptive learning system.
