Awards

  1. Winner of the Coding 4 a Cause (C4C:EU) contest at the AAATE conference 2015.
    News: German and English
    Statement: Stated one of the judges, Mike Paciello, founder and CEO of The Paciello Group in New Hampshire, USA: "I am inspired by the Johannes Kepler University students! To watch 3 of our brightest young people develop a mainstream application that ensures the accessibility of SVG images to users with disabilities, is a testimony to the success of the C4C program. Their ingenuity and strong determination to solve a complex challenge, tells me that our students are learning how to design and develop accessible information technologies! Congratulations JKU, your students and their mentor, Olaf Drümmer."
