Abstract
AR/VR has a very broad application prospects in the fields of medical,military,industrial,education,entertainment and engineering,which is one of the research hot spots in the wearable electronic field at present.The patent trend of AR/VR on HMD technology is analyzed from global and Chinese perspective,specifically discussing patent application situation from the aspects of application number,application regional distribution,principal applicants and so on,and analyzing the gap in technology development and patent protection between domestic innovation body and foreign innovation body.By concluding and analyzing the essential technology of important applicants both abroad and at home,the main technical branches of AR/VR on HMD including image quality aberration correction,HMI control,tracking technology for image adjustment and wear adjustment are summarized,of which the technical development route,technical development trend and important patent node technology of optical system and eye tracking are studied deeply,and the development trend of AR/VR on HMD in the above technical branch is predicted.关键词
