When users have only one free hand to operate smartphones, interaction with 3D virtual environment(VE) is restricted. We propose MagicCube, a cube with 5 DOF that perfectly integrates navigation and selection in 3D VE, to address this problem. Three sets of opposing faces are assigned to feature faces with translation, rotation, and selection. Any operation can be performed by dragging the corresponding face. Further, by rotating the cube, users can choose the displayed faces and adjust their relative position according to personal preference. A comparative analysis showed that it could effectively reduce the finger's visual occlusion as well as improve the accuracy and stability of interaction operations.
