Classification, Application, Challenge, and Future of Midair Gestures in Augmented Reality

Abstract

Augmented Reality (AR) technology provides many opportunities to enhance people's experience in interacting with data. Midair gesture, a natural interaction mode in AR, interacts with virtual elements without any auxiliary devices. It has become a hot topic of interest for researchers with the development of gesture recognition technology. From the perspective of user experience, the types of midair gesture, gesture recognition technology, applications were discussed. The challenges of air gesture interaction from two aspects of user experience and technology were analyzed, and the importance of collaborative gesture and low-cost user experience in the future were emphasized. Finally, the application prospect of air gesture interaction distance education, medical health, industry, office, and so on is discussed.
