[publication] Emotion Detection: Application of the Valence Arousal Space for Rapid Biological Usability Testing to enhance Universal Access

A Draftversion of our publication “Emotion Detection: Application of the Valence Arousal Space for Rapid Biological Usability Testing to enhance Universal Access” at this year HCII Conference is now online available.
Abstract:

Emotion is an important mental and physiological state, influencing cognition, perception, learning, communication, decision making, etc. It is considered as a definitive important aspect of user experience (UX), although at least well developed and most of all lacking experimental evidence. This paper deals with an application for emotion detection in usability testing of software.
It describes the approach to utilize the valence arousal space for emotion modeling in a formal experiment. Our study revealed correlations between low performance and negative emotional states. Reliable emotion detection in usability tests will help to prevent negative emotions and attitudes iproducts. This can be a great advantage to enhance Universal Access.

[publication] A Study on the Compatibility of Ubiquitous Learning (u-Learning) Systems at University Level

A Draftversion of our publication “A Study on the Compatibility of Ubiquitous Learning (u-Learning) Systems at University Level” at this year HCII Conference is now online available.
Abstract:

Graz University of Technology has a long tradition in the design, development and research of university wide Learning Management Systems
(LMS). Inspired by the iPhone Style, the available system has now been extended by the addition of a mobile viewer, which grants the student mobile accessibility to all available online content. In this paper, we report on the lessons learned within a study on user experience with this specially designed LMS mobile viewer. The User Experience (UX) was measured by application of a 26 item questionnaire including the six factors Attractiveness, Perspicuity, Efficiency, Dependability, Stimulation and Novelty, according to Laugwitz et al. (2008). The results showed high rates of acceptance, although the novelty of our approach received a surprisingly low rating amongst the novice end users.

[publication] Mixing Content and Endless Collaboration – MashUps: Towards Future Personal Learning Environments

A Draftversion of our publication “Mixing Content and Endless Collaboration – MashUps: Towards Future Personal Learning Environments” at this year HCII Conference is now online available.
Abstract:

The recent movement by major Web services towards making many application programming interfaces (APIs) available for public use has led to the development of the new MashUp technology, a method of merging content, services and applications from multiple web sites. The new technology is now being successfully applied in the academic community to enrich and improve learning and teaching applications. This paper examines its implementation and use, discusses methods and styles of usage and highlights the advantages and
disadvantages of client and server application, based on related work and recent experiences gathered with a large university-wide open learning management system (WBT-Master/TeachCenter of Graz allows lecturers to use diverse web resources.

[publication] Intuitive E-Teaching by Using Combined HCI Devices: Experiences with Wiimote Applications

A Draftversion of our publication “Intuitive E-Teaching by Using Combined HCI Devices: Experiences with Wiimote Applications” at this year HCII Conference is now online available.
Abstract:

The wide availability of game based technologies and sophisticated e-Learning possibilities creates new demands and challenges on Human–Computer Interaction and Usability Engineering (HCI&UE). Solid research in HCI must support improvement in learning ability and creativity for both teachers and students. According to recent market surveys the Wii remote controller or Wiimote is currently more wide spread than standard Tablet PCs and is the most used computer input device worldwide. As a collection of many sensors, also including Bluetooth technology, accelerometers and IR sensors, Wiimote is of great interest for HCI experiments, especially in the area of e-Learning and e-Teaching. In this paper, we present results gained from the investigation of the potential of Wiimote as both a standard input device – such as mouse or presenter – and as a gesture and finger tracking sensor. We demonstrate, on the basis of examples from e-Teaching, how easily everyday gestures can be interpreted in regular computer applicationhardware modules and some additional software modules.

[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.

[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.
