Mosaicing a Wide Geometric Field of View for Effective Interaction in Augmented Reality

In this paper, we have addressed the usability issue of augmented reality systems. In order to overcome the lack of view into the interaction space in nominal AR systems, we proposed to create and use a mosaiced image as a cost effective and practical solution. One of the obvious problem is that even if the view span is increased by the mosaicing, because of the fixed and limited resolution/size of the display(either HMD or upright display), the content must be viewed in smaller scale. Yang et al. has found out that increasing the geometric field of view can be tolerated to some degree without much degradation in task performance [3]. In our pilot experiment, a comparison of our mosaiced AR display to the nominal set up improved task performance when the task involved manipulation of many tangible props in a relatively wide area. Our future work is to conduct a more formal usability study and address other AR usability issues.
