TouchScope: A Hybrid Multitouch Oscilloscope Interface

Heinz, M., Bertel, S., & Echtler, F. (2017). TouchScope: A Hybrid Multitouch Oscilloscope Interface. In Proceedings of the 19th ACM International Conference on Multimodal Interaction (S. 269–273). New York, NY, USA: Association for Computing Machinery. http://doi.org/10.1145/3136755.3136765

Abstract

We present TouchScope, a hybrid multitouch interface for common off-the-shelf oscilloscopes. Oscilloscopes are a valuable tool for analyzing and debugging electronic circuits, but are also complex scientific instruments. Novices are faced with a seemingly overwhelming array of knobs and buttons, and usually require lengthy training before being able to use these devices productively. In this paper, we present our implementation of TouchScope which uses a multitouch tablet in combination with an unmodified off-the-shelf oscilloscope to provide a novice-friendly hybrid interface, combining both the low entry barrier of a touch-based interface and the high degrees of freedom of a conventional button-based interface. Our evaluation with 29 inexperienced participants shows a comparable performance to traditional learning materials as well as a significantly higher level of perceived usability.

Low Cost Rapid Acquisition of Bidirectional Texture Functions for Fabrics

Azari, B., Wüthrich, C. A., & Bertel, S. (2017). Low Cost Rapid Acquisition of Bidirectional Texture Functions for Fabrics. In 25th International Conference in Central Europe on Computer Graphics, Visualization and Computer Vision (WSCG 2017). Plzen, Czech Republic.

Abstract

Creating photo realistic images from real word complex materials is a great challenge: the reflectance function of materials, especially fabrics, has glossy or specular highlights, reflectance anisotropy and retroreflections. This increases greatly the complexity of rendering. Bidirectional Texture Functions (BTFs), i.e. 2D textures acquired under varying illumination and viewing directions, have been used to render complex materials. However, the acquisition of textures for BTF requires up to now expensive setups and the measurement process is very timeconsuming as the directional dependent parameters (lighting and viewing directions) have to be controlled accurately. This paper will present in detail a new low cost programmable device for the rapid acquisition of BTF datasets. The device allows to acquire BTF databases at a fraction of the cost of available setups, and allows to experiment when a texture resolution and sample density increase in the parameter space is not perceivable by an observer of the renderings. The paper proves that using smaller resolution textures and decreasing the samples in parameter space does not lead to a loss of picture quality.

"Physical Touch-Based Rotation Processes of Primary School Students"

Bertel, S., Wetzel, S., & Zander, S. (2017). "Physical Touch-Based Rotation Processes of Primary School Students". In Spatial Cognition X (S. 19–37). Philadelphia, PA, USA: Springer International Publishing.

Abstract

We present a novel method for deriving solution strategies used when solving rotation tasks. Process-based findings about physical rotation are obtained from an analysis of how angular disparity between stimuli changes over time. Data on angular disparity was gathered through a study on mental and physical rotation with 37 primary school students between the ages of 8 and 11. For controlling physical rotation, students used touch-based input on our iOS app Rotate it!, which also logged their interactions. Data on changes of angular disparity was used in the construction of Markov models. The models were employed to generate sets of synthetic angular disparity time courses, based on which we identified three distinct rotation-based solution strategies. Our analysis has implications for understanding processes involved in physical and mental rotation alike. It helps to lay grounds on which novel interactive diagnostic and training tools for spatial skills can be developed.

Underlying Processes of an Inverted Personalization Effect in Multimedia Learning – An Eye-Tracking Study

Zander, S., Wetzel, S., Kühl, T., & Bertel, S. (2017). Underlying Processes of an Inverted Personalization Effect in Multimedia Learning – An Eye-Tracking Study. Frontiers in Psychology, 8, 2202. http://doi.org/10.3389/fpsyg.2017.02202

Abstract

One of the frequently examined design principles in multimedia learning is the personalization principle. Based on empirical evidence this principle states that using personalized messages in multimedia learning is more beneficial than using formal language (e.g., using ‘you’ instead of ‘the’). Although there is evidence that these slight changes in regard to the language style affect learning, motivation and the perceived cognitive load, it remains unclear, (1) whether the positive effects of personalized language can be transferred to all kinds of content of learning materials (e.g., specific potentially aversive health issues) and (2) which are the underlying processes (e.g., attention allocation) of the personalization effect. German university students (N = 37) learned symptoms and causes of cerebral hemorrhages either with a formal or a personalized version of the learning material. Analysis revealed comparable results to the few existing previous studies, indicating an inverted personalization effect for potentially aversive learning material. This effect was specifically revealed in regard to decreased average fixation duration and the number of fixations exclusively on the images in the personalized compared to the formal version. These results can be seen as indicators for an inverted effect of personalization on the level of visual attention.
