<p>A hand-held electronic writing instrument (Figure 1) comprises a writing tip (6) for marking a surface and a pressure sensor (10) located at the writing tip (6) for emitting a pressure signal once the writing tip (6) contacts the writing surface (3). An accelerometer sensor (20) is also located at the writing tip (6) for sensing the acceleration of the tip (6) over the surface (3) and emitting an acceleration signal based on the acceleration of the tip (6). The pressure signals and acceleration signals are transmitted to a processing circuit (30) located within the implement. An analog-to-digital converter (38) is used to convert the signals into digital code which is recorded in a recording chip (39) within the instrument. A power source (40) is used to power the electronics of the implement. The writing implement is used in conjunction with a receiver (60) capable of receiving digital information such as a computer (60) having a translation package which translates the digital information in order to determine the original markings made by the writing tip (6) on the writing surface (3). The translated markings are displayed on a display (61).</p> |
