Pen and input method digital pen system

摘要

To be able to perform a display screen provided away from the digital pen, the pen input to the intersection of the direction in which the digital pen point. By the digital pen rod-shaped periodically transmits a signal containing information about the direction of its own, to detect the position and orientation in three-dimensional space of the digital pen on the basis of the signal, the digital pen system, length of the digital pen and a, and a receiving apparatus for calculating the intersection between the display screen of the display device and the extension line in the direction, and causes the input pen to the position of the intersection point to the display device.
