Designing an augmented reality multimodal interface for 6dof manipulation techniques

Abstract

Augmented Reality (AR) supports natural interaction in physical and virtual worlds, so it has recently given rise to a number of novel interaction modalities. This paper presents a method for using hand-gestures with speech input for multimodal interaction in AR. It focuses on providing an intuitive AR environment which supports natural interaction with virtual objects while sustaining accessible real tasks and interaction mechanisms. The paper reviews previous multimodal interfaces and describes recent studies in AR that employ gesture and speech inputs for multimodal input. It describes an implementation of gesture interaction with speech input in AR for virtual object manipulation. Finally, the paper presents a user evaluation of the technique, showing that it can be used to improve the interaction between virtual and physical elements in an AR environment.
