Patent ID: 8154514

Claim:
A remote control device comprising: an orientation sensing unit that senses an orientation of a device in a three-dimensional space; an axis determining unit that determines which axis from among three axes in the three-dimensional space with which the device is most parallel according to the orientation of the device in the three-dimensional space; a direction input unit that receives a selection command input of one of two directions that are parallel to the axis with which the device is most parallel and are in opposite directions; and a transmission unit that transmits a control signal to move a predetermined graphics object in a direction corresponding to the selection command along the determined axis, wherein the axis determining unit determines the axis with which the device is most parallel according to whether the orientation is within a critical range among critical ranges of three spatial axes; and wherein if the determining unit determines that a first axis of the three axes in the three-dimensional space is most parallel with the device, the control signal causes the predetermined graphics object to move along the first axis, and if the determining unit determines that a second axis of the three axes in the three-dimensional space is most parallel with the device, the control signal causes the predetermined graphics object to move along the second axis.
