Abstract
A writing or drawing tip device for attachment to a touch screen stylus or handle has a rigid body of conductive material with a forward end mandrel having a rounded or elliptical tip, at least one layer of compressible material extending over the tip to produce a deformable rounded tip, and a retaining device which secures the compressible layer to the body at a location to the rear of the rounded tip. The deformable tip is applied to a touch screen to develop a contact patch between the compressible material layer and screen sufficient to trigger an input on the screen, with the amount of force applied to the tip determining the size of the contact patch.

20. A stylus tip device for a touch screen stylus, comprising:
-
a rigid tip body of conductive material having a rear end and a forward end, the rear end configured for attachment to a handle, and a mandrel extending up to the forward end, the mandrel having a rounded forward tip; at least a first layer of compressible material extending over the tip and at least part of the mandrel of the tip body; the rounded forward tip and compressible material layer together forming a rounded, pressure sensitive, deformable touch screen tip which is configured to flatten and form a contact patch when the rounded tip is applied against a capacitative touch screen, the size of the contact patch increasing with increased force applied by a user of the device; and the compressible material layer being secured to the tip body at a location spaced rearward from the rounded forward tip and not being secured to the rounded tip. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
