The Augmented Reality technology has been developed for more than 40 years. The core of the Augmented Reality technology is a combination of virtual objects with the real world. The difference of the Augmented Reality and the Virtual Reality is that Augmented Reality can be operated according to the position and angle of the images gained by the camera in real time and then the virtual objects can be appended to correspond to the real one in the picture. By superimposing virtual objects onto the ones gained from the real environment by using the smart mobile devices, and a variety of sensors and wireless network in coordination, the augmented reality can then provide more information in a real environment. Therefore, the augmented reality technology has thus been applied in many fields, including games, education, design, travel and tour planning, etc.
