【摘要】：虛擬現(xiàn)實是以人機交互技術為核心、結合了多領域高新技術成果的綜合性技術,它以自然、智能的交互方式實現(xiàn)人與計算機之間的互動,提高了人機交互的用戶體驗和效率。2016年以來,在國內外知名企業(yè)的帶動下,虛擬現(xiàn)實領域成為當前創(chuàng)新創(chuàng)業(yè)的焦點之一。專利分析是一種較為客觀的評價方法,有助于揭示技術發(fā)展趨勢、行業(yè)布局狀況,有助于相關主體提高其技術研發(fā)水平、制定有競爭力的攻防戰(zhàn)略。通過對專利分析實證研究文獻進行調查發(fā)現(xiàn),在現(xiàn)有研究中,尚缺乏對與虛擬現(xiàn)實技術較為全面、深入的分析。人機交互技術是虛擬現(xiàn)實技術的重要組成部分。通過對人機交互技術科技文獻的分析,發(fā)現(xiàn)了該技術的演進路線和近年來的研究熱點。對虛擬現(xiàn)實技術中三種較為重要的交互技術的相關專利進行檢索,共獲得4194條專利數(shù)據。通過分析虛擬現(xiàn)實交互技術及其重點領域的專利申請量變化情況,發(fā)現(xiàn)虛擬現(xiàn)實交互技術目前處于快速發(fā)展階段,其中基于計算機視覺的交互是該領域的熱點領域,多涉及數(shù)字數(shù)據處理技術。在全球專利布局中,美國和中國是相關專利公開數(shù)量最多的兩個地域,美國籍和日本籍企業(yè)類主體、中國籍院校類主體的專利申請量最多。在對各主體的專利活動情況的分析中,發(fā)現(xiàn)企業(yè)為主要的專利活動主體,且活躍年份數(shù)越多的大型企業(yè)更偏向于采取收購專利的專利布局策略;結合專利引證和申請量等指標,發(fā)現(xiàn)專利申請量多大的主體更加注重對專利技術的后續(xù)保護和持續(xù)性開發(fā),而專利質量較高的主體在這方面則存在不足;通過建立各主體之間的專利引證網絡,發(fā)現(xiàn)了引用關系強的主體之間存在著較為密切的合作或直接競爭關系;通過建立以專利分類號為統(tǒng)計依據的技術共現(xiàn)網絡,得到各主體在不同技術領域的專利布局情況和各主體之間的競爭或合作關系。最后,分析了國內的專利競爭態(tài)勢以及我國專利活動主體的大致情況,包括了各主體的構成類型、專利申請趨勢、專利文獻質量、專利法律狀態(tài)以及技術領域布局等方面。我國在虛擬現(xiàn)實交互技術領域的專利布局,既要注重當前的熱點領域,也要有針對性地對其他領域進行專利布局以形成自己的特色。各類主體應當注重對技術的持續(xù)性開發(fā)和地域攻防布局,同時應提高專利撰寫質量,發(fā)揮專利制度的保護作用。企業(yè)應加強與院校、研究型主體的合作,促進我國目前的研究型專利活動轉向應用型專利活動,以適應國內外企業(yè)主導的競爭態(tài)勢。
[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.
