[publication] Shadow Expert Technique (SET) for interaction analysis in educational systems

Our publication on „Shadow Expert Technique (SET) for interaction analysis in educational systems“ for this year HCII International 2011 is as draft version online available.
Abstract:

This paper describes a novel usability method called Shadow Expert Technique (SET), which was applied on the learning management system of the Graz University of Technology in two different trials, with focus on consistency and visual complexity. This is the summary of the development of this new method and the approach to generalize it as a new way to get deeper insight into interaction processes.

[publication] iPhone/iPad Human Interface Design

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.

[conference] USAB 2010: HCI in Work & Learning, Life & Leisure

The 6th Symposium of the Workgroup HCI&UE of the Austrian Computer Society will take place in Carinthia (Southern Austria) this year from Sept. 16th to Sept. 17th.
The topics are structured alongside (but not limited to) the following three dimensions:

  1. Special user groups (children, elderly, healthcare professionals,
    tourists, students, teachers, …)
  2. Issues on practical application of HCI in the work place (process
    aspects, HCI patterns, cost/benefit analyses, …)
  3. Future trends in HCI, …

Here you will finde the Call for Papers [CfP] and some other details.

[podcast] [iTunesU] iPhone Application Development

Wir bieten ab diesem Sommersemester iPhone Application Development im Rahmen der Vorlesung AK Medientechnologien an der TU Graz an:

Die Lehrveranstaltung ‚AK Medientechnologies‘ (Advanced Topics of Media Technologies) beschäftigt sich mit der Applikationsentwicklung auf mobilen Geräten am Beispiel des iPhones.
Hierzu wird eine überblicksmäßige Einführung in die Software-Entwicklung für das iPhone OS gegeben. Studierende sollen nach diesem „Crashkurs“ die Möglichkeit haben, sich selbst in den Entwicklungswerkzeugen zurecht zu finden, selbst die für die Softwareentwicklung weiterführende Dokumentation zu finden, und selbst Software für iPhone OS zu entwickeln und zu verteilen.

Auf iTunesU sind nun neben den Vorlesungsfolien auch alle Aufzeichnungen als Podcast online.
Meine Präsentation der HCI Guidelines ist gleich hier verfügbar.

[conference] USAB 2009 „Usability & HCI Learning from the Extreme“

uni_linzDie USAB 2009 findet heuer vom 9. – 10. November 2009 in Linz unter dem Motto „Usability & HCI Learning from the Extreme“ statt.

Our 2009 topic is Human–Computer Interaction for eInclusion (HCI4eIn), culminating in the 5th annual Usability Symposium USAB 2009.

Mission Statement: “Interfacing the Interface” for a better eInclusion!

Information and Communication Technology (ICT) pervaded many parts of our daily lives. Due to its flexibility (multimedia connected with multimodality) it offers a huge potential for people with disabilities and others with functional limitations to interact with electronic systems and services.

Hier geht es zur Webseite / Programm. Wir werden auch mit einer Publikation / Präsentation vertreten sein und freuen uns auf spannende Diskussionen – cu there.

[publication] Interactive Technology for Enhancing Distributed Learning: A Study on Weblogs

Our contribution to this year HCI 2009 conference about „Interactive Technology for Enhancing Distributed Learning: A Study on Weblogs“ is now online available.
Abstract:

In this study, it was investigated whether, and to what extent, Web 2.0 technologies, actually Weblogs, can be a suitable instrument for enhancing the practice of distributed learning. In educational settings, which are based on traditional lectures many students begin serious study shortly before the exam. However, from previous empirical research, it is known that the practice of distributed learning is much more conducive to retaining knowledge than that of massed learning. A 2*2 factorial design (within – repeated measures) with pre-test and post-test in a real life setting was applied; the study lasted for the whole summer term 2007. Participants were N=28 computer science undergraduates of Graz University of Technology. We randomly assigned them to two groups of equal size: The experimental group given the Weblog treatment are referred to as Group W; whereas the control group with no access are referred to as Group C. Students of group W were instructed to use the Weblog for developing their paper and studying during the lecture and they were requested not to reveal their group affiliation. The results showed that performance scores of group W were significantly higher than that of group C. This demonstrates that Weblogs can be an appropriate instrument to supplement a classical lecture in order to enable deeper processing of information over a longer period of time, consequently resulting in enhanced learning performance.
