Augmented Reality (AR), enhancing a user´s perception of the real world with computer generated entities, and mobile computing, allowing users to access and manipulate in-formation anytime and independent of location, are two emerging user interface technologies that show great promise. The combination of both into a single system makes the power of computer enhanced interaction and communication in the real world accessible anytime and everywhere. This paper describes our work to build a mobile Augmented Reality system that supports true stereoscopic 3D graphics, a pen and pad inter-face and direct interaction with virtual objects. The system is assembled from off-the-shelf hardware components and serves as a basic test bed for user interface experiments related to computer supported collaborative work in Augmented Reality. It also describes some applications we are developing in the area of location based computing.
