AR-based Inorganic Chemistry Learning Support System using Mobile HMD

In this paper, we proposed inorganic chemistry learning support system using smartphone. For the proposed environment, smartphone, VR viewer and some markers are used as interface. To construct smartphone based HMD, user attach smartphone to VR viewer. By wearing HMD on user's head, user don't need to hold smartphone with his/her hand. To perform the virtual experiment in the proposed system, a user operates marker in recorded area of smartphone's camera. Based on recorded image, proposed system constructs virtual environment. Constructed virtual environment is displayed on smartphone's display. By watching smartphone's display and moving and arranging markers on the desk, user can confirm process of virtual experiments. By using proposed system, user can perform virtual experiment in various locations without PC and camera. In this paper, effectiveness of proposed approach was shown.
