Digitale Lehre an und rund um der Technischen Universität Graz
Im Rahmen der ELCH 2010 Preisverleihung an der Karl-Franzens-Universität in Graz halte ich heute den Impulsvortrag „Hat mLearning an Universitäten Zukunft?“ – viel Spaß mit den Folien:
Tomorrow I have to gave a short overview about all our activities in the field of e-Learning at Graz University of Technology. Here are the slides:
Das 10. Interview für L3T hat sich ganz spontan im Zug ergeben – Herwig hat dort einfach mit seinem e-Reader gelesen und wir haben dies genutzt um ihm ein paar Fragen zu stellen. Er erzählt seine Sichtweise, wann er ihn einsetzt und auch welche Vor- und Nachteile das Gerät besitzt bzw. ob es Zukunft hat …. Vielen lieben Dank jedenfalls, für seine Eindrücke:
Das Seminarprojekt über „eModeration“ neigt sich mit der heutigen Abschlussveranstaltung dem Ende zu. Online gibt es hier noch die Slides für die Veranstaltung:

Our workshop proposal on „iPhone/iPad Human Interface Design“ held at the 6th Symposium (USAB 2010) of the Workgroup HCI&UE of the Austrian Computer Society in Carinthia (Southern Austria) is now online. The slides are already available here and also a short video summary.
Abstract:
In this tutorial, we will present the Human Interface Guidelines for both iPhone and iPad and offer hands-on experience in designing user interfaces for these devices. We will also discuss how to integrate the guidelines in higher education and give examples from our lecture on iPhone application development. The goal of the tutorial is to provide the participants with a basic understanding of the iPhone Human Interface Guidelines and enable them to review and design iPhone apps according to the standards.

Im Rahmen einer Bachelorarbeit haben wir die Möglichkeiten von Twitteranalyse-Tools angesehen und danach wurde eine kleine Applikation entwickelt für eine Keywörter Analyse.
Die Arbeit steht ab sofort hier zur Verfügung und ich bedanke mich bei Thomas für die Möglichkeit es zu veröffentlichen:
Our publication about „The XAOS Metric – Understanding Visual Complexity as measure of usability“ held at the 6th Symposium (USAB 2010) of the Workgroup HCI&UE of the Austrian Computer Society in Carinthia (Southern Austria). The slides are already available here.
Abstract:
The visual complexity of an interface is a crucial factor for usability, since it influences the cognitive load and forms expectations about the subjacent software or system. In this paper we propose a novel method that uses entropy, structure and functions, to calculate the visual complexity of a website. Our method is evaluated against a well known approach of using the file size of color jpeg images for determining visual complexity. Both methods were applied on a dataset consisting of images of 30 different websites. These websites were also evaluated with a web survey. We found a strong correlation for both methods on subjective ratings of visual complexity and structure. This suggests both methods to be reliable for determination of visual complexity.

Beim 6. und letzten Online Meeting des Seminars „eModeration“ haben wir über allgemeine Präsentationsregeln geredet. Die Slides sind nun online.
Damit ist die Online Phase auch beendet und wir freuen uns auf die abschließende Präsenzveranstaltung. Zusammenfassend sei festgehalten, dass es wie immer sehr schwer war in den Online Meetings die technischen Hürden zu meistern, aber wir denken es ist nach einiger Eingewohnung gut gelaufen.

Our publication on ”A Simple MVC Framework for Widget Development” for this year ECTEL-Conference is now online. Slides have been already published here.
Abstract:
The great advantage of a Rich Internet Application (RIA) is the improved performance, since a great part of the processing can be done on the client-side rather than the server-side. For many web-based RIAs JavaScript (JS) is the most common programming language as it is popular as a script language for browsers. While server-side programming languages have the advantages of object oriented programming paradigm, JS bases on objects with a specific object literal notation. Using design architectures such as Model View Controller (MVC) in JS reduces the code complexity and allows semi-parallel application development. It causes an easier and much less time-consuming development on further extensions of RIAs. Web-based widgets are actually RIAs. In this paper a very simple design pattern for widget development is introduced that bases on MVC design architecture. The pattern has been applied during the development phase of widgets for the Personal Learning Environment (PLE) at Graz University of Technology (TU Graz) and
is mostly appropriate for students and RIA developers who have beginner knowledge/experience in JS programming.
