Stylus providing variable line width as a function of pressure
First Claim
Patent Images
1. A drawing device comprising:
- a housing;
a tip positioned at one end of the housing;
a force sensor coupled to the tip to detect pressure applied by a user through the housing to the tip; and
a transmitter that transmits signals representative of a line width desired by the user based on the amount of pressure applied to the tip.

Abstract
A digital input stylus includes a sensor to determine pressure being applied to the stylus. The determined pressure is translated to a line thickness for display on a display device. The pressure is digitized and communicated to the display device, such as a tablet PC. Settings in the tablet PC are modifiable by a user to determine the format of the line thickness, correlating detected pressure with desired thickness.
