Using QUALCOMM’s Augmented Reality Software Development Kit, we have created two social augmented reality applications that support on-device content creation for the Android phone. Our initial application, Life Markup, allows users to place virtual content in the real world. Our second application, Virtual Room Designer, focuses the idea of Life Markup to allow users to arrange virtual furniture in a real room. In order to develop intuitive interfaces for the applications, we conducted a series of user studies.
