This study has investigated on the obstacles to the production of social network games. It also tried to find their production tools in order to remove existing obstacles, which will guide to design and create new production tools. The new production tool is designed to make it easy for Terrain, UI, and Object tools to be used for essential functions, game linkage, and testing. The detailed explanation about the structure design and functions of the new production tool is also written and added for better understanding. To test its functions, texture of the animation application was printed on top of the production tool. The test result showed stable processing speed. I also made a 􋺵Farming􋺶 trial-game to test how easily social network games can be developed. As a result, more stable framework, which could not be made without production tools, was able to be designed and even the time spent on developing it became shortened.

In recent years, a variety of motion recognition devices for HMD have been presented. Operation method using the motion recognition is the best one for the characteristics of HMD that the user's sight is obstructed in using the contents. The recent HMD devices have the head-tracking feature recognizing the movement of the user's head. However, the operation of the avatar using head-tracking lead to the depressed usability caused by the unfamiliar use. In this paper, the avatar was moved using the head tracking function built in HMD as a basic operating device, which enhanced the usability of the contents by showing the movement of avatar whose human motion capture was linked to the position of the user's head in the third person point of view. The user is able to trace his own position to operate the contents by the avatar in virtual space, which would reveal the potential for utilization of the user interface by which the avatar is controlled through inputting the function of tracking direction.
