One of the barriers that prevent augmented reality (AR) from being widely adopted in diverse and complex industrial operations is the lack of adaptive and scalable AR work instruction (ARWI). This paper suggests a systematic method to solve the problem. The proposed method presents an adaptive representation structure that expresses and controls those interrelated aspects of ARWI adaptiveness: authoring, environment, guiding and process control. The proposed method also provides a detailed approach to achieve the adaptiveness of ARWI in its authoring and running process. The ARWI design workflow suggested can incorporate industrial AR elements via on-site operators’ inputs without programming instead of developers or engineers. At the same time, the adaptive ARWI can adapt to different people, environment objects, and processes of complex industrial operations at runtime. This advantage brings ARWI design closer to real applications and makes the technology more adoptable. Three user studies, using the disassembly operations of an aircraft engine’s hydraulic actuator and other two practical cases, are used to assess the proposed method and support our claims.

China's communications industry is an important part of the electronic information industry, and plays a significant role in the national informatization process. In 2006, China issued its National Plans for Medium and Long-term Development of Science and Technology (2006-2020) (NPMLDST). Since 2006, there has been a rapid increase in the number of citations of China's international papers in the field of communications. In accordance with the goals listed in the NPMLDST, China needs to overtake several competitors by 2020 to be among the top five countries in the field of natural science field. By comparing two Essential Science Indicators (ESI) (i.e., the total number of citations and the number of citations per paper) for China and other countries, China's annual growth rate is found to exceed that of other influential countries in the field of science and technology, and exhibits evident growth-type characteristics. Besides, our study also shows that the shortage of high-quality academic papers in China is the main obstacle to improving the impact of China's academic publications.
