Augmented Reality (AR) is aimed at integrating virtual information into real world to enhance the perception ability of reality. The paper mainly presents an AR system that can complete some interactions between the user and the smartphone based on touch screen and body motion. There are three contents in this system. The first part is the building of AR scenes in Unity3D on the basis of real-time mapping access to the WebCamTexture Class. The second part is the interaction based on the touch screen with the method of Raycast. The third part is the interaction based on the body motion with the help of Gyro Sensor in the smartphone. Experimental results show that there is a good effect in the touch-screen interaction to realize some actions such as translation, rotation, scaling, or any combination of these. And it is also effective in the body-motion interaction to control the virtual objects acting according to the user's body motion.
