This paper presents findings from an ongoing investigation into the public understanding of augmented reality (AR) technologies. Despite AR technologies becoming increasingly available to the general public, perceptions of its use and capabilities still vary based on a number of factors. To explore this concept, a survey was conducted into individual's definition of AR and classification of AR and traditional technologies. The themes elicited from responses indicated that digital and real components were both perceived as key characteristics, but the synthesis of these components was not significant. Responses also indicated that the public is still relatively unfamiliar with AR technologies, but familiarity does lend itself to a better understanding of what is or isn't AR. Trends in public perceptions of AR are presented, but also identify the need for more investigation into the public understanding of AR technologies.
