NCKU unveils digital painting pen with intuitive operation
Tainan, Taiwan, Jan. 4, 2013
A research team led by Dr. Fong-Gong Wu, a Distinguished Professor of Department of Industrial Design at National Cheng Kung University (NCKU), southern Taiwan, has developed a digital painting pen intuitive operations, exploring the need on painting creation for different ages.
“The design integrates the possible factors as touch sense, hand gesture, ankle into the input mechanism of digital painting pen in the cause of creating the intuitive and innovative digital painting system,” according to Dr. Wu.
It is an electronic pen that can be controlled intuitively, said Dr. Wu adding that it can detect changes in painting automatically, thus fixing the hassle of bringing different painting tools and simplifying complex painting procedures.
He said, the design applied the structure of response between the pen itself and the controlling system to create changes on the screen based on the different brush type, hues, brush thickness and so on.
This allows users to intuitively control the painting pen, thus creating the diverse effects of changes created by different drawing brushes, which makes the painting with the digital pen more like using the usual paint brush.
The digital painting pen has 3 functions where there are 2 operating methods for each function. The first function, namely change of brush type (i.e. watercolor, crayon, rainbow pen), uses the pressure on the nib of the pen and the holding position of the pen to operate the digital painting pen.
The second function, change of brush thickness, allows users to use the digital pen based on the cross-sectional area and the inclination angle of the nib of the pen.
The third function is the choice of color, where color can be changed by gently sliding the pen using fingers and selected by gently rotating the pen.
Dr. Wu noted that current computer painting software has approximately 10 categories of usable functions, including resize, undo, color, Bezier curve, moving canvas, transparency, and stroke thickness.
However, adding to the functions mentioned above, the new design developed into approximately 20 more functions such as pen rotation, pressure, size change with force.
According to the experiment on children aged ranged from 4 to 7, the digital painting pen helps the children master the skill of changing pen stroke, thus allowing them to concentrate while drawing and preventing concentration problems due to complex function interface, said Dr. Wu.
At the same time, it could also increase the frequency of switching pen strokes, ensuring more richness on the lines drawn and making drawing more enjoyable for young kids.
General painting products using the intuitive control mode offer experience similar to the traditional painting method. Therefore, digital painting pens are more appealing to users.
Dr. Wu pointed out that in the coming future the application of this technology will be extended to other major touch panel products as an input tool for general painting or word processor tasks.
Besides, this technology will also be integrated into other 3C products to enhance the function of intuitive control action of gesture input, thus enabling users to operate the product more quickly and more convenient.
