Embodiment Construction

[0030] One or more embodiments of the invention include a drawing assistance system that assists users in creating original paintings or sketches. In particular, the drawing assistance system provides an image on top of which the user can draw. In particular, one or more embodiments provide an image on which a user can draw strokes. As the user draws the stroke, the user stroke is geometrically corrected by moving the stroke toward where the line "should" be drawn. To further improve the lines drawn by the user, the drawing assistance system makes parameter adjustments to emphasize "correctly" drawn lines and de-emphasize "incorrectly" drawn lines.

[0031] The systems and methods disclosed herein may allow users with little or no training to create pleasing paintings. As mentioned above, the systems and methods disclosed herein can make geometric corrections to the user's strokes. As used herein, the term "geometrically correct" or "geometrically correct" refers to moving,...

Abstract

Methods for providing drawing assistance to a user sketching an image include geometrically correcting and parametrically adjusting user strokes to improve their placement and appearance. As a user draws a stroke, the stroke is geometrically corrected by moving the stroke toward a feature of the image the user is intending to draw. To further improve the user strokes, parametric adjustments are made to the geometrically-corrected stroke to emphasize “correctly” drawn lines and de-emphasize “incorrectly” drawn lines.

Description

technical field [0001] One or more embodiments of the invention generally relate to providing drawing assistance to a user. More specifically, one or more embodiments of the invention relate to systems and methods for geometrically correcting and parametrically adjusting user strokes to aid in drawing. Background technique [0002] Drawing is an important form of communication and expression. Unfortunately, beginners to painting are sometimes hesitant to paint because they feel they lack the creative and technical skills to produce works of satisfactory visual quality. Novices often claim that they are not creative or that they do not know how to draw. Novice painters often face challenges that cause them to lack confidence and produce lower quality work. [0003] One of the challenges for beginners in painting is how to draw beautiful lines. Beginners are often unsure about line placement, shape, and curvature. This uncertainty can cause a novice to draw slowly, making...
