These tourism landmarks or objects are often promoted by the use of electronic media (such as internet) and printed media (such as brochure). However, this kind of media is too common in today's advancement level of technology. In this paper, Augmented Reality (AR) technology is used to help providing more attractive, informative, and interactive means of advertising the tourism objects as mobile application. The application, which is called iARTour (Informative Augmented Reality Tour), can be run on Android platform with three main features. The user can: view 3D models of a landmark from image marker as well as text marker, listen an explanatory audio which contains description of the landmark, and search for a certain landmark in database. The image marker is printed in a form of brochure as supplementary advertising media. This new way of interaction to promote tourism object is also one of implementations of Human and Computer Interaction field.
