[thesis] Erschließung und Analyse von Twitter Analyse Tools
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:
[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.

[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.
