Pens

For the measurement of the pen-tip position in two dimensions, i.e., the writing plane, a wide variety of techniques exists. Using resistive, pressure sensitive, capacitive, or electromagnetical transducer technology, the position of a pencil can be accurately measured. Sometimes, even acceleration transducers inside the pen are used to measure pen movement [185].

Table 3.3 gives an overview of parameters that may be controlled with a pen.
