Studies were conducted to measure novelty and learning retention while utilizing augmented reality (AR) in two learning systems. The first taught participants the basics of guitar and either a melody or scale using an AR guitar with an LED-embedded fret board. The guitar provided digital representations of learning patterns that users would otherwise need to visualize during the learning process. Results of three studies indicate that participants using the AR learning tool were able to perform more of the melody or scale after two-weeks. The second taught participants the basic functioning and anatomy of the heart, using either an AR model or a fiberglass model. Learning and technology acceptance were measured. Results indicated that the AR learning tool was as effective for participant learning when compared to the conventional fiberglass model learning tool. Furthermore, the AR learning tool was rated more enjoyable, curiosity inducing, and easier-to-use than the fiberglass model
