In this paper, we investigate a method to integrate Augmented Reality (AR) into a foreign language learning environment for task-based activities. We accomplish that task by focusing mainly on two objectives. First, AR markers can be applied to integrate some objects into the language learning environment as learning materials. Second, movement of an AR-tagged object used in the activities can be recognized and tracked, based on the AR marker's positional information. AR technology is the integration of digital information with the user's environment in real time. AR uses the existing environment and overlays digital information on it. We developed a prototype tool with the AR markers, and conducted an experiment to investigate the objectives mentioned above. In the experiment, 22 university students participated in the activities with the prototype tool. Concerning the first objective, the results of the experiment suggest that the prototype tool is easy to use as learning materials. The tool with the AR markers shows the possibility of achieving task-based style activity objectives. Concerning the second objective, an AR-tagged object moved by the learner was successfully recognized and tracked by the system in the activities. The results suggest that the AR marker's positional information could help track the learner's movement in the learning activities. It should be noted that the ability to track an AR marker sometimes suffers from the problems caused by the amount of light in the classroom. Evenly distributed light is preferable when trying to identifying and detecting AR markers.
