Abstract
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.
