The Golden Bullet: A Comparative Study for Target Acquisition, Pointing and Shooting
Proceedings of the 2019 11th International Conference on Virtual Worlds and Games for Serious Applications (VS-Games) [4-6 Sept. 2019; Vienna, Austria]

Abstract anzeigen
In this study, we evaluate an interaction sequence performed by six modalities consisting of desktop-based (DB) and virtual reality (VR) environments using different input devices. For the given study, we implemented a vertical prototype of a first person shooter (FPS) game scenario, focusing on the genre-defining point-and-shoot mechanic. We introduce measures to evaluate the success of the according interaction sequence (times for target acquisition, pointing, shooting, overall net time, and number of shots) and conduct experiments to record and compare the users' performances. We show that interacting using head-tracking for landscape-rotation is performing similarly to the input of a screen-centered mouse and also yielded shortest times in target acquisition and pointing. Although using head-tracking for target acquisition and pointing was most efficient, subjects rated the modality using head-tracking for target acquisition and a 3DOF Controller for pointing best. Eye-tracking (ET) yields promising results, but calibration issues need to be resolved to enhance reliability and overall user experience.

Improving relevant subjective testing for validation: Comparing machine learning algorithms for finding similarities in VQA datasets using objective measures
Signal Processing: Image Communication, vol. 74, no. May, pp. 32-41
2019
DOI: 10.1016/j.image.2019.01.004
Abstract anzeigen
Subjective quality assessment is a necessary activity to validate objective measures or to assess the performance of innovative video processing technologies. However, designing and performing comprehensive tests requires expertise and a large effort especially for the execution part. In this work we propose a methodology that, given a set of processed video sequences prepared by video quality experts, attempts to reduce the number of subjective tests by selecting a subset with minimum size which is expected to yield the same conclusions of the larger set. To this aim, we combine information coming from different types of objective quality metrics with clustering and machine learning algorithms that perform the actual selection, therefore reducing the required subjective assessment effort while trying to preserve the variety of content and conditions needed to ensure the validity of the conclusions. Experiments are conducted on one of the largest publicly available subjectively annotated video sequence dataset. As performance criterion, we chose the validation criteria for video quality measurement algorithms established by the International Telecommunication Union.

Linking Bitstream Information to QoE: A Study on Still Images Using HEVC Intra Coding
Advances in Electrical and Electronic Engineering, vol. 17, no. 4, pp. 436-445
2019
DOI: 10.15598/aeee.v17i4.3625
Abstract anzeigen
The coding tools used in image and video encoders aim at high perceptual quality for low bitrates. Analyzing the results of the encoders in terms of quantization parameter, image partitioning, prediction modes or residuals may provide important insight into the link between those tools and the human perception. As a first step, this contribution analyzes the possibility to transcode reference images of three well-known image databases, i.e. IRCCyN/IVC, LIVE and TID2013, from their original, older formats to HEVC; thus creating a homogeneous database of 327 HEVC encoded images accompanied with bitstream parameters and values obtained from objective and subjective assessments. Secondly, it analyzes some of the HEVC intra coding parameters regarding their influence on the image quality by using machine learning, namely Support Vector Machine - Regression.

Optical and Mechanical Properties of Highly Transparent Glass-Flake Composites
Journal of Composites Science, vol. 3, no. 101, pp. 1-17
2019
DOI: 10.3390/jcs3040101
Abstract anzeigen
In this paper, the dynamic mechanic and optical properties of composites made of Polyvinyl
Butyral (PVB) and Micro Glass Flakes (MGF) with matching refractive indices (RIs) are investigated.
The composite is produced by a slurry-based process using additional blade casting and lamination.
It can be shown that a high degree of ordering of the MGF in the polymer matrix can be achieved
with this method. This ordering, combined with the platelet-like structure of the MGF, leads to very
efficient strengthening of the PVB with increasing content of the MGF. By carefully adjusting the
RIs of the polymer, it is shown that haze is reduced to below 2%, which has not been achieved with
irregular fillers or glass fibers.

Aluminum Coated Micro Glass Spheres to Increase the Infrared Reflectance
Coatings (Special Issue "Current Research in Thin Film Deposition: Applications, Theory, Processing, and Characterisation"), vol. 9, no. 3
2019
DOI: 10.3390/coatings9030187
Abstract anzeigen
The reflective properties of micro glass spheres (MGS) such as Solid Micro Glass Spheres (SMGS, “glass beads”) and Micro Hollow Glass Spheres (MHGS, “glass bubbles”) are utilized in various applications, for example, as retro-reflector for traffic road stripe paints or facade paints. The reflection behavior of the spheres can be further adapted by coating the surfaces of the spheres, e.g., by titanium dioxide or a metallic coating. Such coated spheres can be employed as, e.g., mid infrared (MIR)-reflective additives in wall paints to increase the thermal comfort in rooms. As a result, the demand of heating energy can be reduced. In this paper, the increase of the MIR-reflectance by applying an aluminum coating on MGS is discussed. Aluminum coatings are normally produced via the well-known Physical Vapor Deposition (PVD) or Chemical Vapor Deposition (CVD). In our work, the Liquid Phase Deposition (LPD) method, as a new, non-vacuum method for aluminum coating on spherical spheres, is investigated as an alternative, scalable, and simple coating process. The LPD-coating is characterized by X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), scanning electron microscopy (SEM), and reflection measurements. The results are compared to a reference PVD-coating. It is shown that both sphere types, SMGS and MHGS, can be homogeneously coated with metallic aluminum using the LPD method but the surface morphology plays an important role concerning the reflection properties. With the SMGS, a smooth surface morphology and a reflectance increase to a value of 30% can be obtained. Due to a structured surface morphology, a reflection of only 5% could be achieved with the MHGS. However, post-treatments showed that a further increase is possible.
