[publication] The Modeling of Harmonious Color Combinations …

Our contribution „The Modeling of Harmonious Color Combinations for improved Usability and User Experience (UX)“ to this year International Conference on Information Technology Interfaces is now online available.
Abstract:

This study compares three different models for the calculation and prediction of harmonious color combinations. Therefore a dataset of user rated color combinations was taken from a large online database. The user rating was compared to the outcome of the three models on this dataset in order to test the performance of the models. The first model based on the idea that color combinations are more pleasing the greater their difference in brightness. The second model is a slightly modified version of Ou & Lou (2006) using chromatic difference, lightness sum, lightness difference and hue effect. The last model was invented by us and is based on an experiment of Polzella & Montgomery (1993). From the outcome of their experiment we generated a lookup table for single color rating. This rating
is then used in a formula, which is able to evaluate the color harmony for color combinations up to five colors. This model also performed best in the overall comparison between the three color harmony models.

[video] Open Source Multitouch Technology

Auf der ED-Media Konferenz nahm ich an einem Vortrag über den Einsatz von Multitouch Technologie in der Lehre teil. Sehr spannend fand ich, dass hierbei auf eine Open Source Lösung zurückgegriffen wurde: Community Core Vision

Community Core Vision, CCV for short (formally known as tbeta), is a open source/cross-platform solution for computer vision and machine sensing. It takes an video input stream and outputs tracking data (e.g. coordinates and blob size) and events (e.g. finger down, moved and released) that are used in building multi-touch applications. CCV can interface with various web cameras and video devices as well as connect to various TUIO/OSC/XML enabled applications and supports many multi-touch lighting techniques including: FTIR, DI, DSI, and LLP with expansion planned for the future vision applications (custom modules/filters).

[publication] Is Your University Ready For the Ne(x)t-Generation?

Our publication about „Is Your University Ready For the Ne(x)t-Generation? “ at this year ED-Media Conference is now online.
Abstract:

Abstract: At Graz University of Technology a survey about the hardware equipment and the Web2.0 skills among students of the first semester took place for the second time. This paper reflects the results of that two years evaluation. It answers the questions whether the net-generation already has arrived at universities or not and which consequences this fact has on the teaching and learning behaviors as well as infrastructural aspects of a university. Although young students are technologically increasingly well equipped they do not exhaust the potential of their devices or the potential of uncommon Web2.0 applications yet. Nevertheless the applications and communicational ways of a student’s average usage are signals not to be ignored by a university management. They not only indicate a dawning basic change of a typical student’s life but demand a rethinking of essential structural elements at universities right now.
