Poster: A pilot study on stepwise 6-DoF manipulation of virtual 3D objects using smartphone in wearable augmented reality environment

In general, 6 degrees of freedom (DoF) manipulation of 3D virtual objects requires cumbersome external tracking installations to localize and track the input device in a normal wearable augmented reality (WAR) environment. In this paper, a smartphone-based 6-DoF manipulation method is proposed to avoid the use of complicated installations. First, the proposed 6-DoF manipulation method (3-DoF translation and 3-DoF rotation) exploits various embedded sensor information of the smartphone. Transfer functions are then designed to transfer the phone´s 6-DoF control gain to the 3D display space´s object manipulation gain. According to the experimental results, the quadratic transfer function was superior to the linear and acceleration functions with less completion time and errors.
