The co-evolution of technology and society spawned evolving organizational forms of innovation. In recent years, with the further integration of information technology and production technology, the traditional boundary of manufacture and innovation activities is blurred. The booming Maker Movement is playing an important role in this process. Based on literature review and participatory observation, this paper traces the history of the development of maker movement, and provides a preliminary analysis of the concept, models and characters of maker movement. This paper suggests that the development of Maker Movement is based on the expanding global network of Makerspaces, characterized with open source, peer innovation. It is becoming a booster for the digital world to subvert the physical world. Essentially, it represents a new trend of public participation of innovation.

The concept of Mapping of Knowledge Domains and the CiteSpace(a information visualization tool) get a lot of attention quickly since they introduced in domestic academia, the relevant literature spring up like mushroom in a variety of domestic information science journals. But we find the knowledge visualization tool is "abused" and "misused" seriously by reading more than 500 papers that applied CiteSpace ,which shows that academic circles is lack of sufficient understanding of the methodology function of Mapping of Knowledge Domains. This article makes a deeper interpretation on CiteSpace from four aspects, design philosophy, theoretical basis, applying process and application function, which will benefit domestic scholars to deepen the understanding of the tool, and apply the tool more flexibly and effectively in scientific research.
