【摘要】：虛擬現(xiàn)實(shí)是以人機(jī)交互技術(shù)為核心、結(jié)合了多領(lǐng)域高新技術(shù)成果的綜合性技術(shù),它以自然、智能的交互方式實(shí)現(xiàn)人與計(jì)算機(jī)之間的互動,提高了人機(jī)交互的用戶體驗(yàn)和效率。2016年以來,在國內(nèi)外知名企業(yè)的帶動下,虛擬現(xiàn)實(shí)領(lǐng)域成為當(dāng)前創(chuàng)新創(chuàng)業(yè)的焦點(diǎn)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(shù)發(fā)展趨勢、行業(yè)布局狀況,有助于相關(guān)主體提高其技術(shù)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(shí)證研究文獻(xiàn)進(jìn)行調(diào)查發(fā)現(xiàn),在現(xiàn)有研究中,尚缺乏對與虛擬現(xiàn)實(shí)技術(shù)較為全面、深入的分析。人機(jī)交互技術(shù)是虛擬現(xiàn)實(shí)技術(shù)的重要組成部分。通過對人機(jī)交互技術(shù)科技文獻(xiàn)的分析,發(fā)現(xiàn)了該技術(shù)的演進(jìn)路線和近年來的研究熱點(diǎn)。對虛擬現(xiàn)實(shí)技術(shù)中三種較為重要的交互技術(shù)的相關(guān)專利進(jìn)行檢索,共獲得4194條專利數(shù)據(jù)。通過分析虛擬現(xiàn)實(shí)交互技術(shù)及其重點(diǎn)領(lǐng)域的專利申請量變化情況,發(fā)現(xiàn)虛擬現(xiàn)實(shí)交互技術(shù)目前處于快速發(fā)展階段,其中基于計(jì)算機(jī)視覺的交互是該領(lǐng)域的熱點(diǎn)領(lǐng)域,多涉及數(shù)字?jǐn)?shù)據(jù)處理技術(shù)。在全球?qū)＠季种?美國和中國是相關(guān)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(jié)合專利引證和申請量等指標(biāo),發(fā)現(xiàn)專利申請量多大的主體更加注重對專利技術(shù)的后續(xù)保護(hù)和持續(xù)性開發(fā),而專利質(zhì)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(wǎng)絡(luò),發(fā)現(xiàn)了引用關(guān)系強(qiáng)的主體之間存在著較為密切的合作或直接競爭關(guān)系;通過建立以專利分類號為統(tǒng)計(jì)依據(jù)的技術(shù)共現(xiàn)網(wǎng)絡(luò),得到各主體在不同技術(shù)領(lǐng)域的專利布局情況和各主體之間的競爭或合作關(guān)系。最后,分析了國內(nèi)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(gòu)成類型、專利申請趨勢、專利文獻(xiàn)質(zhì)量、專利法律狀態(tài)以及技術(shù)領(lǐng)域布局等方面。我國在虛擬現(xiàn)實(shí)交互技術(shù)領(lǐng)域的專利布局,既要注重當(dāng)前的熱點(diǎn)領(lǐng)域,也要有針對性地對其他領(lǐng)域進(jìn)行專利布局以形成自己的特色。各類主體應(yīng)當(dāng)注重對技術(shù)的持續(xù)性開發(fā)和地域攻防布局,同時應(yīng)提高專利撰寫質(zhì)量,發(fā)揮專利制度的保護(hù)作用。企業(yè)應(yīng)加強(qiáng)與院校、研究型主體的合作,促進(jìn)我國目前的研究型專利活動轉(zhuǎn)向應(yīng)用型專利活動,以適應(yīng)國內(nèi)外企業(yè)主導(dǎo)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.
