    Convolutional neural networks and data augmentation strategies are tuned, producing a model of 87.12% accuracy for the verification of 2,640 human signatures. Two approaches are used to successfully attack the model with false-acceptance of forgeries. Robotic arms (Line-us and iDraw) physically copy real signatures on paper, and a conditional Generative Adversarial Network (GAN) is trained to generate signatures based on the binary class of ‘genuine’ and ‘forged’. The 87.12% error margin is overcome by all approaches; prevalence of successful attacks is 32% for iDraw 2.0, 24% for Line-us, and 40% for the GAN.

1.How does the pen plotter work?

The UUNA TEK® iDraw functions as a pen plotter, representing a straightforward form of robotic technology. Its primary role involves guiding a pen or other implement, affixed to the pen holder, along specified vector lines, curves, and paths as per user instructions. All capabilities of the machine, whether it be drawing graphics, producing text, or authenticating documents, emanate from this foundational function. The device exhibits proficiency in rendering virtually any composition formulated through a set of lines.

In practical terms, using the UUNA TEK® iDraw resembles the operation of a traditional printer, with the crucial distinction that documents must be constructed using paths rather than pixels for optimal performance.

1.Can I download the manual?

Yes, you can download the software with the user manual here>>>

2.How long does plotting take?

The plotting time for UUNA TEK® iDraw is not fixed, unlike a (raster-based) inkjet or laser printer. It is contingent on the distance the pen needs to travel. UUNA TEK® iDraw typically moves at a pace comparable to a human hand, depending on your settings, resulting in variable plotting times.

Comparing this to the question of how long a human takes to write or draw on a piece of paper is apt. For instance, addressing an envelope might generally take a minute or two, while creating intricate artwork could extend to a matter of hours. The same variability applies to UUNA TEK® iDraw. Notably, our speed ranks highest in the market compared to any other competitors.

3.Is the speed of UUNA TEK® iDraw adjustable?

Yes, the speed of UUNA TEK® iDraw is adjustable to cater to your specific preferences, offering a tradeoff between faster completion and higher precision.

For reference, the wedding invitation text featured in our video provides a good indication of the typical writing speed when prioritizing higher neatness, slightly slower than regular human handwriting.

4.Can I input my signature?

Certainly! The most effective method is to directly capture your signature as you sign it, such as on a phone or tablet screen. This allows UUNA TEK® iDraw to reproduce your signature exactly as you wrote it during the capture.

5.Can it replicate my handwriting?

Yes, but it involves an additional step of creating a custom font. Our UUNA TEK® iDraw is compatible with Hershey fonts and the Defects extension, which can introduce handwriting-like "defects" to your text. This ensures that text arranged in perfectly even rows, as seen with a handwriting font in MS Word, doesn't appear overly "robotic" and retains a more authentic handwriting feel.

6.Can you replicate handwriting from scans?

No, not in the way you might expect.

Certainly, you can scan handwritten text, use a bitmap tracing tool to trace it, and then plot it. UUNA TEK® iDraw will faithfully plot the paths you provide.

However, it's important to note that, with only rare exceptions, automatic tracing of scanned handwriting tends to produce a somewhat unnatural imitation of handwriting. We generally advise against incorporating this method into any workflow due to the potential drawbacks in replicating authentic handwriting.
