Studies regarding augmented reality (AR) books generally indicated its advantages on reading performance. Positive attitude toward the usage of AR books and acceptance of usability with AR books was also responded by users including samples of students and parents. AR books create a new experience of reading; and the further exploration of user experience beyond usability when using AR applications can be considered. The present study hence invited 29 pairs of parents and their children coming from different regions in Taiwan to join a shared AR book reading activity. Each parent was interviewed for understanding their perceived user experiences and expected user experiences of the selected AR book in this study; and the qualitative data was analyzed through phenomenographic method. The results showed that the parents perceived using the AR book in both emotional senses (e.g., joy and surprise) and cognitive senses (e.g., increasing attention). However, some of them perceived negative experiences such as interrupting traditional book reading by AR. Also, AR books are expected to provide parents with rich interaction and vivid animation for experiencing the augmented information. The diverse user experiences of the AR book reading perceived by the parents could be elaborated to further explore their relationships with intention to use and usage behaviors. The characteristics of perceived and expected user experiences responded by the parents found in this study can also be the basis for the practical design of AR books in the future.
