On June 28 and 29, 2007, sixth Auto-ID Labs CJK workshop was held at ICU (Information and Communications University) in Daejoen, Korea. The Auto-ID Labs CJK workshop is a workshop jointly organized by three Auto-ID Labs located in East Asia (CJK is an abbreviation of China, Japan, and Korea). It started in 2005 aiming at sharing of studies of each lab and promoting the collaboration among labs. In this workshop, twenty studies from three research domains of Auto-ID Labs. (Business model/Applications, Software/Network, and Wireless system/Hardware) are presented. This time, in order to increase collaboration among us, we also have a team building sports event. This new activity successfully enhances our communication. CJK Auto-ID Labs are expecting to announce new projects started from this workshop.
