Interaction in Augmented Reality: Challenges to Enhance User Experience

Augmented reality (AR) is an emerging technology that has yet to be a mature consumer product. Given that user experience plays a significant role in the success of new technologies, the development of appropriate AR user interfaces needed. As such, defining the challenges to current AR user interfaces is a steppingstone to enhancing user experience. There are three principal components of interaction in AR systems: the user, the user interface and the virtual content. Examples from the literature are provided to identify the challenges to each interaction component. Both the layout of the AR interaction component and the identified challenges aim to help and inform researchers and AR software developers to choose the AR interaction aspects that best serves their purpose, while also contributing to the enhancement of user experience.
