Interaction techniques in mobile Augmented Reality: State-of-the-art

Abstract

Augmented Reality (AR) has recently evolved and one of its evolutions is mobile AR. A key point of mobile AR is being reactive, which imposes real-time constraints. Hence, developing and improving interaction methods for AR have gained a wide interest in the past few years with the massive growth of mobile technology. In this paper, we introduce state-of-the-art interaction techniques for mobile AR, categorized into tangible and intangible as well as a comparative study between them. According to the results of the studied techniques, tangible techniques proved to be easier for users whereas intangible techniques are more engaging. As a result, intangible techniques need more research and enhancements.
