为了研究基于触控技术的图形用户界面交互技术的发展趋势，在实际审查经验的基础上，以SIPOABS数据库 为检索入口，采用IPC分类号结合关键词进行检索，对涉及触控技术的GUI交互领域的专利分布进行了分析统计，结果表明近 几年来我国在该领域专利申请量增长较快，但因我国相关技术起步较晚，核心专利主要掌握在国外企业手中。

In order to study the development trend of graphical user interface interaction technology based on touch technology, on the basis of actual examination experience, IPC and keywords are used to search in SIPOABS database, and the patent distribution in GUI interactive field which involves touch technology is analyzed statistically. Results show that in recent years, the patent applications in our country have grown rapidly, but as the technology started late, the core patent is mainly in the hands of foreign enterprises.
