Large-scale computing and data processing technologies throughout the other sub-areas of VR provide the VR system effective operation of the overall security.Computing and data processing technology include data collection,data storage,data transformation and data transmission links.Since the computational complexity of VR systems is high and meanwhile requires higher real-time,computing and data processing capabilities directly determine the efficiency and reliability of VR system operation.
Simulation is an experimental technology,creating a complex system computer lab environment to simulate the system operation.In order to give users the most realistic experience in vision,audition and tactus,etc.,the successful VR system should carry the simulation of the physical behavior out in the virtual level.Collision detection is an important technique in system simulation.As the collision detection requires higher real-time and precision,it becomes the technical bottleneck in VR and other real-time simulation system.Collision detection is also an indispensable of one of the key technologies in VR.
Three-dimensional(3D)sound technology is an import part of creating the virtual environment.Three-dimensional sound localization technology is the core technology of the three-dimensional virtual sound system.In addition,user interacting with the virtual world by voice is a high-level goal in VR system.Automatic Speech Recognition(ASR)and Text to Speech(TTS)are the key-technology in VR.If combined with ASR and TTS,users may communicate with virtual environment with simple voice,so this technology has the outstanding value in VR environment.
Head Mounted Display(HMD)device,widely used in three-dimensional display,is the technology of three-dimensional image capture.Together with the three-dimensional image display technology,it belongs to three-dimensional image technology.In the research,the number of HMD patent is so large that the average citation frequency of selected key-technology patent reaches 141,and clustered as a separate class based on co-citation intrinsic characteristics in clustering analysis.
Strictly speaking,in VR,semiconductor light emitting devices and materials technology can be defined as three-dimensional image display technology.Since the average citation frequency of two key-technology patents(US5643826、US5923962)amounts to 756 and their disclosure time is not early(1997,1999),we regard them as crucial and fundamental technologies,shown separately in the article.In the current light emitting devices,organic light-emitting diode(OLED)highlights the advantages and gives good development prospects.According to DisplaySearch's prediction,by 2015,OLED revenues will increase from ＄591,000,000 in 2008 to 60 billion,with the annual compound growth rate(CAGR)growing to 40％4.In the field of VR technology,OLED in HMD with the carrier of video glasses and portable theater has been widely used.At the same time,OLED in digital soldiers and VR games also has significant advantages.
5 Concluding remarks
Abundant technology inheritance and development information are contained in patent citations.The method of obtaining valuable technical information from patent citations by using multivariate statistical analysis is simple and easy to operate.This approach allows key technology selection based on patent citation analysis to play a better role in decision support of enterprise technology innovation.Based on co-citation theory of patent citation analysis,the authors mined key technologies of virtual reality through multivariate statistical analysis,and illustrated each sub-area of VR key technologies.
