This paper introduces an augmented reality authoring tool that allows users to edit and publish an examination application with the Augmented Reality (AR) interface. The AR authoring system in this paper is constructed with the help of ARToolKit, a widely used open source for AR. This unique system can help users with no programming knowledge to build AR applications quickly and efficiently. 2D text, 3D content editing, and finger-based interaction are the three major components found in the AR authoring environment. AR content created by the user is stored in a separate txt file for easy sharing, modification, and reusability. A user testing of the published examination application was also conducted, and participants in the testing offered generally positive feedback.
