The transferability of handwriting skills: from the Cyrillic to the Latin alphabet

Pierre Dillenbourg, Thibault Lucien Christian Asselborn, Wafa Monia Benkaouar Johal

Do handwriting skills transfer when a child writes in two different scripts, such as the Latin and Cyrillic alphabets? Are our measures of handwriting skills intrinsically bound to one alphabet or will a child who faces handwriting difficulties in one scri ...

Extending the Spectrum of Dysgraphia: A Data Driven Strategy to Estimate Handwriting Quality

Pierre Dillenbourg, Thibault Lucien Christian Asselborn, Mateo Chapatte

This paper proposes new ways to assess handwriting, a critical skill in any child’s school journey. Traditionally, a pen and paper test called the BHK test (Concise Evaluation Scale for Children’s Handwriting) is used to assess children’s handwriting in Fr ...

Transfer of graphene on polymeric foil

Marsha Mary Parmar, Guilhem Edouard Baptiste Noiraud

Since its creation in 2004 [1], graphene has become an important subject in the scientific community. From the Scotch tape method, many techniques have been developed to fabricate and manipulate graphene flakes. This project aims to transfer graphene flake ...

Automated human-level diagnosis of dysgraphia using a consumer tablet

Pierre Dillenbourg, Thibault Lucien Christian Asselborn, Wafa Monia Benkaouar Johal, Lukasz Kidzinski, David Cohen, Thomas Dany Sylvain Gargot

The academic and behavioral progress of children is associated with the timely development of reading and writing skills. Dysgraphia, characterized as a handwriting learning disability, is usually associated with dyslexia, developmental coordination disord ...

Virtual reading of a large ancient handwritten science book

Giorgio Margaritondo, Frédéric Kaplan, Alessandra Patera, Fauzia Albertin, Marco Stampanoni

We present a fundamental development step of a new technique to read and digitize ancient handwritten documents. Chemical analysis by x-ray fluorescence and x-ray tomography enabled us to decipher words and drawings from inside a closed, 200-pages 18th cen ...

Color Reproduction of Metallic-Ink Images

Roger Hersch, Vahid Babaei

We study the color reproduction of full-color metallic-ink images. Full-color metallic-ink images are prints whose contributing colorants are exclusively made of colored metallic inks. Due to the presence of metallic particles, metallic inks show a metal-l ...

Properties and Printability of Inkjet and Screen-Printed Silver Patterns for RFID Antennas

Nico de Rooij, Danick Briand, Jinyu Jason Ruan, Francisco Molina Lopez

We report the modeling, and geometrical and electrical characterization, of inkjet and screen-printed patterns on different polymeric substrates for use as antennas in radio-frequency identification (RFID) applications. We compared the physical and electri ...

Juxtaposed Color Halftoning Relying on Discrete Lines

Roger Hersch, Vahid Babaei

Most halftoning techniques allow screen dots to overlap. They rely on the assumption that the inks are transparent, i.e. the inks do not scatter a significant portion of the light back to the air. However, many special effect inks such as metallic inks, ir ...
