We have studied hands-free interface using head motion that enable to access both the real world and PC in order to support the gesture of the disabled and bedridden patients. In this paper, we extend the accessible range to 3D by introducing 3-dimensional kinematics and its coordinate system, and modify the pointing speed determination function in order to improve the access speed. In addition, we propose a new performance index to evaluate operability corresponding to the 3-dimensional space access. Finally, we experimentally confirm the effectiveness of the proposed method by some evaluation tests as for the pointing ability and the robot operation.
