Appl. No.:

13/312502

Inventors:

Kelly Allan Dunagan - La Habra CA, US

International Classification:

G06F 3/033

US Classification:

345179

Abstract:

A stylus device for writing or drawing on a touch screen has an elongate barrel for gripping by a user and a stylus tip of rigid, non-compressible material secured to one end of the barrel and having an end face comprising a working surface configured for contact with the touch screen while writing or drawing. The stylus tip is oriented at a predetermined offset angle to the longitudinal axis of the barrel, such that the working surface is not perpendicular to the central longitudinal axis of the barrel. The working surface is applied to a touch screen to develop a contact patch between the working surface and screen sufficient to trigger an input on the screen.

International Classification:

G06F 3/033

US Classification:

345179

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.
