Research on the Key-technology Selection of Virtual Reality Based on Patent Citation Analysis

摘要：

Based on the data of Derwent Innovation Index from 1963 to 2009, the authors construct a patent analysis dataset of virtual reality by retrieving the patents through keywords and classification numbers.The authors also reveal technical hot points, key technologies of virtual reality through patent citation analysis and multivariate statistical analysis, and then acquire CTI (competitive technical intelligence) for enterprises.
