Embodiments of the invention introduce new multi-touch gestures and transient graphic helpers that mimic howreal-life rules, compass, protractor, and other drawing tools behave and how these tools are used without disrupting the sketching activities.
By taking advantage of multi-touch, transient graphical affordances and digital paper concepts, these new drawing aid tools can furthermore be utilized with a greater freedom by dissociating the drawing aid tools position on the digital canvas and thepencil/brush activities on the digital canvas itself. In other words the digital drawing aids’direction/angle can be enforced anywhere on the digital canvas and the artist does not need to always position the drawing aid precisely where he wants that direction/angle to be applied to his next brush/pencil stroke.

The embodiments of the invention introduce a “soft” tool activation/deactivation method that also mimics where/how these real life tools are usually organized and placed around the physical canvas. This new tool activation method, which consists of tracking multi-touch inputs traversing from the borders of the digital canvas (seen above, as the star points), provides a drawing environment that flows naturally without enforcing rigid/precise versus free drawing/sketching modes.
The drawing aid enables the control of the precision and ending behavior of the brush stroke. The user can set a relative distance or angle for the drawing aid. Thereafter, each subsequent brush stroke is influenced by the prescribed distance or angle.
