In spite of high expectations for augmented reality (AR) technology, many smartphone AR applications have failed and terminated their services in Korea because of low usage rates. As failures of smartphone AR applications have increased, investigating factors that influence users' continuance intention to use the AR applications become an important topic. This study develops a theoretical model that explains continuance intention of users based on AR and motivation theories, and empirically examines the influencing factors with collected data from smartphone AR application users. The results showed that information quality was the most influencing factor for AR continuance intention among AR factors, while perceived enjoyment was not a significant antecedent. The implications of this study provide additional insights for smartphone AR researchers and developers.
