Using RF identification tags in writing instruments as a means for line style differentiation

Abstract

One aspect of the invention involves the output of a radio frequency (RF) identification tag by a writing instrument to indicate ink color or another characteristic associated with a line style parameter of the writing instrument. The RF identification tag is a wireless signal that uniquely identifies the line style parameters, such as physical-ink or virtual-ink color, produced when using the writing instrument. A writing tablet receives the RF identification tag and signals a computing device, responsible for displaying graphical representations made on the writing tablet, to display a portion of the graphical representation formed by that writing instrument with the characteristics of the line style parameters specified by the RF identification tag.
