[vortrag] Wie verändern Neue Medien den Unterricht?

Es ist zwar noch einige Zeit hin, aber nachdem es schon eine Ankündigung gibt, will ich auch noch drauf hinweisen. Man hat mich gebeten für die Reihe Vita activa „Wissen schaffen“ einen Vortrag über e-Learning zu halten. Der vorgeschlagene Titel meinerseits lautet: Digitales Lehren und Lernen: Wie verändern Neue Medien den Unterricht? und findet am 4. April 2011 von 19.00 – 21.00 an der Universität Graz im Zentrum für Weiterbildung statt.
Hier gibt es die detaillierte Einladung.

[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.

[publication] The XAOS Metric – Understanding Visual Complexity as measure of usability

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.

[sem1p] Präsentation über Präsentation

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.

[publication] A Simple MVC Framework for Widget Development

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.
