Embodiment Construction

[0016] Such as figure 1 The digital writing device shown generally includes: (a) a pen body (1), wherein the pen body (1) includes:

[0017] - a pen cartridge (5) connected to the nib for drawing ink onto the writing surface (20) during writing;

[0018] - a pressure sensor (6) for detecting the pressure of the pen tip on the writing surface (20); and

[0019] - pen body transducer module (30) for Figure 3-6 The illustrated triangulation method identifies, tracks and records pen body position, wherein the transducer module (30) includes:

[0020] - at least two pen body sensors, preferably an ultrasonic sensor (2) and an infrared sensor (3), for transmitting position identification signals to or receiving position identification from a set of reference medium sensors (13, 14) signal for identifying the position of the pen body (including the nib) on the writing surface (20), by calculating the signal transmission distance d 1 (i.e. from the time-of-flight of a signal betw...

Abstract

A digitized writing apparatus of this invention comprising a portable set of a pen body and a reference medium wherein the pen body and the reference medium each comprising at least a set of pen bodyposition-identifying sensors capable of transmitting and receiving a succession of position-identifying signals between said pen body and reference medium during a writing task. The pen body and the reference medium further comprise at least a set of magnetometer and accelerometer to assist the ultrasonic and infrared systems in identifying the position coordinates, distances, and angles of the pen body in relations to the reference medium. A set of controller and memory units are further introduced to control and coordinate the activation and deactivation of the position-identifying sensors and to record the pen position locations and coordinates during a writing task. A communication module may be optionally installed to enable wireless transmission of a written data to an external device such that the written information can displayed in real-time.

Description

technical field [0001] The present invention relates to a digitizing writing device and its communication system, wherein the digitizing writing device comprises a pen body and a reference medium with an embedded transducer module capable of transmitting and receiving a pen position recognition signal. The pen body and reference medium also include magnetometers and accelerometers to help the transducer module recognize or calculate pen position and pen movement tracking information and forward said information to storage space in the storage unit of the pen body or reference medium. Written information, such as strings of characters or graphics, can be simultaneously and wirelessly transmitted to an external electronic display device, or stored for later viewing on an external electronic display device. Background technique [0002] A conventional digitized writing device (such as a digital pen, a wireless pen, or a stylus) typically includes a pen body and a reference poi...
