Highly realistic driving environments will help to provide reliable and valid findings to ensure safety and usability of advanced in-car cockpits. Nevertheless, real car driving studies are difficult to standardize, more time consuming and expensive. Thus, one economizing suggestion is the implementation of immersive driving environments within simulator studies to provide users with a more realistic awareness of the situation. This paper discusses research investigating the influence of immersive driving environments during dual-tasks regarding eye movements. The results of the driving simulator study (N=20) suggest more visual availability for driving when high immersive driving environments were applied to the text entry task. © 2014 ACM. Source

Virtual prototypes are essential for engineers to understand the complex structures and arrangements of mechatronic products like automobiles. Currently, Virtual Environments (VE) are used for visual analysis and interaction with virtual models. In the next years more supplementary information will be integrated in the VE, completing the 3D-model. This includes names of single parts, corresponding materials or masses. However, up till now there is little explicit research on the psychological effects of additional text visualization in VE's. For example it unclear if it is possible to visualize the textual information like on paper prints or on 2D displays. The current study empirically compares these types of different output mediums to advise rules for visualization of text in 3D Virtual Environments. Results show, that textual information has to be slightly enlarged for the 3D Virtual Environment. In addition, subjects performed better in conditions with projected textual information compared to real text. © 2013 Springer-Verlag Berlin Heidelberg. Source

In the last years the emotional impact of artifacts became more and more interesting to the field of human-computer interaction research. Despite many models that describe factors of user experience (UX), most of them are of a descriptive nature. In contrast, we propose a theoretical approach, the model of user experience (MUX) that offers an explanation for the emergence of UX starting from the very first interaction steps. Additionally, we present empirical results that support these assumptions of our theoretical approach that were under investigation. In detail we found that affordances as well as standard signals foster users performance on a small time scale (up to 3 sec.). However, these small changes affected peoples UX. Hence we conclude that it is a fruitful approach to start investigating UX on a keystroke level. © 2013 Springer-Verlag Berlin Heidelberg. Source

Steel in Translation | Year: 2013

The uniform elongation of high-strength steel (yield point 500-1400 MPa), with ferrite-bainite, bainite-martensite, and martensite structure, is studied as a function of the production technology (thermomechanical treatment, quenching from furnace temperatures and tempering, quenching from rolling temperatures and tempering). Specifically, the influence of the steel's phase composition, the size of the bainite crystals, the martensite content, and the carbide morphology on its ease of cold deformation is considered. © 2013 Allerton Press, Inc.
