Until now, little research attention in the area of Augmented Reality (AR) has been paid to the cognitive benefits engendered by this emerging technology. AR, the synthesis of computer images and text in the real world (Azuma, 1997), affords a supplement to normal information acquisition that has yet to be fully explored and exploited. AR achieves a more smooth and seamless interface by complementing human cognitive networks, and aiding information integration through multi-modal sensory elaboration, by utilizing visual, verbal, proprioceptive, and tactile memory while the user is performing real world tasks. AR also incorporates visuo-spatial ability, which involves the representations of spatial information in memory. The use of this type of information is an extremely powerful form of elaboration. This study examined four learning paradigms: print (printed material) mode, observe (video tape) mode, interact (text annotations activated by mouse interaction) mode, and select (AR) mode. The results of the experiment indicated that the select (AR) mode resulted in better learning and recall when compared to the other 3 conventional modes of learning. Implications for training and curriculum design are discussed.
