Some people make rough, fast, nonchalant sketches and they look brilliant. For others, it takes hours of blood, sweat and tears to produce drawings that are accurate yet still look unprofessional. The question is why? As a lecturer in cognitive ergonomics at the Rotterdam University of Applied Sciences, I consider human reactions to visual information, and I also teach sketching. So I thought that if I could analyze and describe how our mind reacts to different aspects of handmade sketches, I would be able to teach drawing skills much more easily. I am convinced that this traditional way of learning to draw is fundamentally wrong, because even if people learn to draw accurately, their drawings do not convince.

The line is the most important element. Some good lines are all you need to produce a beautiful drawing. By definition, a line is a geometric figure formed by a point moving along a path in a two- or three-dimensional space.
It can be straight or curved. Lines have a uniform thickness and variable curvature. The best way to create them is with a computer, as I did here: These lines are perfect, but they have fewer characteristics than hand-drawn lines. That is why, despite their perfection, they are quite boring. Lines that are drawn by humans have much more character. They have personality and are much more alive.
They can express creative skill and craftsmanship, and they have a lot more attributes like variable thickness and accuracy, and dynamic features like smoothness, speediness, easiness, fluency and so on.
That is why computer software like SketchBook Pro from Autodesk tries to imitate handmade drawings. The main problem with learning to sketch is that most beginners focus too much on accuracy. They draw slowly and with concentration.
Instead, they look crooked and tentative. In addition, lots of tiny inaccuracies become more prominent because of the erroneous desire to draw everything with one single line. These drawings look unprofessional and uncertain despite the fact that some of them are quite accurate. There is no sign of confidence, ease or dynamism in these drawings, nor any sign of an intelligent creative process. Dynamism is much more important to the human eye than accuracy.
We prefer a drawing that looks dynamic yet less accurate to a drawing that is more accurate yet less dynamic. Look at the following two circles.
Our brain judges emotionally. It will prefer the less accurate but dynamically drawn circle on the left to the more accurate one on the right. That is because dynamic lines express confidence and ease, and these features seem more important to humans than accuracy.
Look at the difference with the perfect orange circle. The drawing on the right is twice as accurate as the drawing on the left, yet the left one looks much better. Of course, you cannot draw very long lines with complex curves as fast as you should to make it look dynamic and smooth. What then? Simply build it up from a set of simple segments that you can draw easily. If all segments are drawn well, the whole line structure will look good.
Besides, your drawing will also acquire a beautiful sense of rhythm. This complex organic contour line of a tree is constructed from a set of very simple elements.
It would be impossible to draw it by hand as one single dynamic line. The Zen moment of drawing. If you look at the work of traditional Japanese artists, you see that they can draw or paint very slowly yet beautifully.
With a lot of practice, it is possible to learn how to draw slowly, but still very fluently. It is something that you cannot force. It is more like a meditative activity, when you concentrate on relaxing the muscles in your arm and just let the movement of your hand flow. The 3D interface was slower than the traditional selects the interaction model to be used. Then draws free-form technique with the experts users, but presents the same timing re- strokes on the canvas or on the mesh and the system automati- sults with non-experts.
We consider these results positive, due to cally creates the deformation on the correspondent region of the their years of training in Maya and compared to their unfamiliarity 3D model. A stroke is represented by a curve and a region is to our sketching interaction models. Another interesting finding of represented by a set of rig elements.
The user can indefinitely this experiment is that the sketching interaction paradigm seems to refine the strokes and save poses at anytime, which can then be require a shorter learning curve when compared to the traditional used as keyframes for animation.
