Abstract
The present invention provides a multi-orientation handwriting trace input device and a method for rotating a coordinate plane thereof, and relates to the field of computer peripheral input devices. The device comprises a coordinate indicator and a data receiver, wherein the coordinate indicator enables trace input within a predefined coordinate plane of the data receiver. The device further comprises a data communication unit and a coordinate plane rotation unit. The data communication unit is provided the data receiver. A processor of the data receiver transfers operation state information of the data communication unit to the coordinate plane rotation unit. The coordinate plane rotation unit rotates the coordinate plane of the data receiver according to the received operation state information of the data communication unit. The present invention can be implemented in a simple and reliable way, and is easy for use by both right-handed and left-handed users. The present invention is adaptive for use at various angles and can find a wide range of applications.
