摘要:
The pen input device has both a movement detection system and a position detection system that collectively track the position of the pen input device during a writing operation on a writing surface. The pen input device has a writing tip capable of performing a writing operation in contact with the writing surface. A controller is operable to activate the movement detection system continuously during the writing operation and to activate the position detection system intermittently during the writing operation. The movement detection system is operable to determine movement data that represent changes between successive positions of the writing tip. The position detection system is operable to determine position data that represents a position of the writing tip on the writing surface.
