Workshop: „GI-Grand Challenge – Erhalt unseres digitalen Kulturerbes“

Am 29.05.2015 findet in der Stadtbibliothek Köln ein Workshop der GI Fachgruppe Knowledge Media Design und der GI Fachgruppe Langzeitarchivierung/Emulation statt. Der Workshop ist offen für Interessenten, allerdings ist die Teilnehmerzahl begrenzt. Weitere Informationen und Anmeldung zum Workshop unter: Knowledge Media Design.


Ziele des Workshops:

Die Gesellschaft für Informatik (GI) hat vergangenes Jahr eine Reihe von sogenannten Grand Challenges der Informatik definiert (siehe https://www.gi.de/themen/grand-challenges-der-informatik.html), in denen besondere Herausforderungen für die zukünftige Entwicklung beschrieben werden. Die Organisatoren dieses Workshops haben in diesem Rahmen die Grand Challenge „Erhalt des digitalen Kulturerbes“ (siehe https://www.gi.de/themen/grand-challenges-der-informatik/digitale-kultur.html) definiert. Hier werden zentrale Fragen von langzeitlichen Erhaltungsaspekten bis hin zum Zugang zu erhaltenem Material gestellt.
Dieser erste Workshop zur GI-Grand Challenge „Erhalt des digitalen Kulturerbes“ beleuchtet das Thema von verschiedenen Seiten mit dem Ziel, eine erste Road Map zur Identifikation und möglichen Beantwortung dieser Herausforderungen zu entwickeln. Dazu werden eine Reihe von Experten/-innen aus Wirtschaft, Wissenschaft und Praxis eingeladen, um die gesammelten Erfahrungen zum Thema in kurzen Impulsreferaten vorzustellen.  Gemeinsam mit den Teilnehmern des Workshops soll dann in ausführlichen Diskussionen eine erste Sammlung von konkreten Herausforderungen und möglicher Lösungsansätze entwickelt und in einem ersten Entwurf einer zukünftigen Road Map gebündelt werden.

Presentation of bachelor/master-project topics

This semester, we offer a number of Bachelor and Master projects in which students have the opportunity to actively participate in ongoing research projects.

We, therefore, cordially invite you to come visit us in our MediaRoom (Z924) on Wednesday, April 15th at 11.45 am. There you will get an overview of open Bachelor and Master projects. The projects will be presented by members of the HCI Group and can be discussed afterwards if any questions remain.


Furthermore, we offer two new courses:

‘Eye Tracking in HCI’ (directed studies) will already start on Monday, April 13th at 15:15 in PZ 901.
In this course, students acquire basic and in-depth knowledge about the functionality of eye trackers and their use in human-computer interaction. This involves a theoretical part where the students impart their knowledge in a presentation, and a practical part where they will gain hands-on experience in using different eye trackers.

‘New Trends in HCI – Role of Visions in HCI’ (seminar) will start on Tuesday, April 14th at 5 pm in PZ 901.
In this seminar we would like to take a look on popular visions in hci (e.g. the vision of ubiquitous computing). Each student will be assigned to one specific vision and will present it in detail. Furthermore we will discuss the influences of the vision on the hci community and whether is has become or will become reality or not.
