【摘要】：虚拟现实是以人机交互技术为核心、结合了多领域高新技术成果的综合性技术,它以自然、智能的交互方式实现人与计算机之间的互动,提高了人机交互的用户体验和效率。2016年以来,在国内外知名企业的带动下,虚拟现实领域成为当前创新创业的焦点之一。专利分析是一种较为客观的评价方法,有助于揭示技术发展趋势、行业布局状况,有助于相关主体提高其技术研发水平、制定有竞争力的攻防战略。通过对专利分析实证研究文献进行调查发现,在现有研究中,尚缺乏对与虚拟现实技术较为全面、深入的分析。人机交互技术是虚拟现实技术的重要组成部分。通过对人机交互技术科技文献的分析,发现了该技术的演进路线和近年来的研究热点。对虚拟现实技术中三种较为重要的交互技术的相关专利进行检索,共获得4194条专利数据。通过分析虚拟现实交互技术及其重点领域的专利申请量变化情况,发现虚拟现实交互技术目前处于快速发展阶段,其中基于计算机视觉的交互是该领域的热点领域,多涉及数字数据处理技术。在全球专利布局中,美国和中国是相关专利公开数量最多的两个地域,美国籍和日本籍企业类主体、中国籍院校类主体的专利申请量最多。在对各主体的专利活动情况的分析中,发现企业为主要的专利活动主体,且活跃年份数越多的大型企业更偏向于采取收购专利的专利布局策略;结合专利引证和申请量等指标,发现专利申请量多大的主体更加注重对专利技术的后续保护和持续性开发,而专利质量较高的主体在这方面则存在不足;通过建立各主体之间的专利引证网络,发现了引用关系强的主体之间存在着较为密切的合作或直接竞争关系;通过建立以专利分类号为统计依据的技术共现网络,得到各主体在不同技术领域的专利布局情况和各主体之间的竞争或合作关系。最后,分析了国内的专利竞争态势以及我国专利活动主体的大致情况,包括了各主体的构成类型、专利申请趋势、专利文献质量、专利法律状态以及技术领域布局等方面。我国在虚拟现实交互技术领域的专利布局,既要注重当前的热点领域,也要有针对性地对其他领域进行专利布局以形成自己的特色。各类主体应当注重对技术的持续性开发和地域攻防布局,同时应提高专利撰写质量,发挥专利制度的保护作用。企业应加强与院校、研究型主体的合作,促进我国目前的研究型专利活动转向应用型专利活动,以适应国内外企业主导的竞争态势。
[Abstract]:Virtual reality is a comprehensive technology based on human-computer interaction technology, which combines multi-field high-tech achievements. It realizes the interaction between human beings and computers in a natural and intelligent way. Since 2016, driven by well-known enterprises at home and abroad, the field of virtual reality has become one of the focuses of innovation and entrepreneurship. Patent analysis is an objective evaluation method, which is helpful to reveal the trend of technology development and industry layout, to improve the level of technology research and development and to formulate competitive strategy of attack and defense. Through the investigation of patent analysis literature, it is found that there is still a lack of comprehensive and in-depth analysis of virtual reality technology in the existing research. Human-computer interaction technology is an important part of virtual reality technology. Based on the analysis of the scientific and technological literature of human-computer interaction technology, the evolutionary route of the technology and the research hotspot in recent years are found. In this paper, 4194 patents of three important interactive technologies in virtual reality are retrieved. By analyzing the changes of patent applications in virtual reality interaction technology and its key areas, it is found that virtual reality interaction technology is in a rapid development stage, in which interaction based on computer vision is a hot field in this field. Most involve digital data processing technology. In the global patent layout, the United States and China are the two regions with the largest number of patent disclosure, American and Japanese enterprises, Chinese universities and colleges have the largest number of patent applications. In the analysis of the patent activities of each main body, it is found that the enterprises are the main body of patent activities, and the large enterprises with more active years prefer to adopt the patent layout strategy of patent acquisition, and combine the patent citation and the amount of application, etc. It is found that the main body with large amount of patent application pays more attention to the subsequent protection and sustainable development of patent technology, while the subject with high patent quality has some shortcomings in this respect; through the establishment of patent citation network among the various subjects, It is found that there is a close cooperation or direct competition relationship among the entities with strong citation relationship, and through the establishment of a technical co-occurrence network based on the patent classification number, The patent distribution in different technical fields and the competition or cooperation among the main bodies are obtained. Finally, it analyzes the situation of domestic patent competition and the general situation of the main body of patent activities in China, including the composition of each subject, the trend of patent application, the quality of patent documents, the status of patent law and the layout of technical field. The patent layout in the field of virtual reality interactive technology in our country should not only pay attention to the current hot field, but also make the patent layout for other fields in order to form its own characteristics. All kinds of subjects should pay attention to the sustained development of technology and the layout of regional attack and defense, and at the same time should improve the quality of patent writing and give play to the protective role of patent system. Enterprises should strengthen the cooperation with colleges and universities and research subjects to promote the current research patent activities in China to turn to applied patent activities in order to adapt to the competitive situation of domestic and foreign enterprises.
