[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.

[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] Usability metrics of time and stress – Biological enhanced performance test of a university wide learning management system

Im Rahmen der USAB 2008 mit dem Thema “HCI & Usability for Education and Work” haben wir einen Beitrag zu “Usability metrics of time and stress – Biological enhanced performance test of a university wide learning management system” erstellt.
Abstract:

This paper describes the modification and outcome of a performance test applied to a university wide learning management system under realistic conditions to identify usability problems and to compare measures such as success rate, task time and user satisfaction with requirements. Two user groups with 20 test users each took part in this study. During the whole test psychophysiological parameters of the test persons were monitored and recorded, in order to find event related stress symptoms. Modifications of the original test allowed a faster analysis of relevant quantitative metrics and the collection of qualitative information.
