中文摘要：

随着科学技术的不断进步，虚拟现实的理论研究得到了快速发展，并获得了广泛应用。本文以Web of Science为数据来源，对虚拟现实领域的相关文章进行了收集、整理及可视化分析；并基于热点学科、关键词共现、文献共被引及聚类、关键词演化趋势以及突增性研究五个方面，探索该领域研究热点及演化趋势。结果表明：虚拟现实领域发文量稳步上升，且美国、中国及欧盟具有不俗的实力；计算机科学、工程、医疗及心理学是该领域的四个热点学科，并将受到持续关注。

英文摘要：

With the development of science and technology, the theory of virtual reality has been rapidly developed and widely used. In this paper, we collect, reorganize, and execute visual analysis on the data of virtual reality in Web of Science. Besides, based on the five aspects of hot topics, co-occurrence of key- words, co-citation and clustering of literatures, the evolution trends of keywords and the study on mutation, we explore the research hotspots and evolution trends in this field. Analysis results show that the number of articles in the field of virtual reality is increasing steadily, and America, China and the European Union have strong research strength; the top four hot subjects are computer, engineering, heal care and psychology, and they will continue receiving more attention in the future.
