Abstract: 
We demonstrate an Augmented Reality (AR) system that utilizes a combination of direct free hand interaction and indirect multimodal gesture and speech interface. A three-dimensional (3D) design sandbox application, featuring online object creation, has been developed to illustrate the use case of our system that supports dual interaction techniques.
