Claim Text:
1. A method of providing drawing assistance to a user sketching an image by geometrically correcting and parametrically adjusting user strokes comprising: detecting a stroke drawn by a user on a touch screen of a client device; comparing the stroke to a guidance map of the image to identify a feature in the guidance map to which the stroke corresponds; geometrically correcting the stroke to create a geometrically-corrected stroke; determining, by the client device, one or more deviations of the geometrically-corrected stroke from the identified feature in the guidance map; parametrically adjusting the geometrically-corrected stroke by emphasizing or de-emphasizing the geometrically-corrected stroke based on the deviations of the geometrically-corrected stroke from the identified feature in the guidance map; and rendering the parametrically adjusted, geometrically-corrected stroke on the touch screen of the client device in place of the stroke drawn by the user.
