description: Virtual Reality (VR) allows us to embody any possible appearance using avatars. Previous work found that the visual appearance of an avatar can affect the user’s behavior – a phenomenon known as the Proteus effect. The illusory feeling of owning a virtual avatar – the body ownership illusion – modulates the Proteus effect. Prior investigations revealed that the time of how long users embody an avatar can affect the extent of the body ownership illusion, however, it is currently unknown whether and how behavioral changes caused by the Proteus effect are moderated by the embodiment time. Therefore, we are planning to conduct a study with 30 participants where we induce the Proteus effect using avatars of different perceived ages to evaluate the effect of embodiment time on walking speed. We hypothesize that the longer users embody an elderly avatar, the slower they will walk in VR. In this proposal, we suggest a study design to evaluate the effect of embodiment time on the body ownership illusion and behavioral changes caused by the Proteus effect in VR.

description: Faraday waves are generated at the air/liquid interface inside an array of square cells. As the free surface inside each cell is destabilizing due to the oscillations, the shape of the free surface is drastically changing. Depending on the value of the frequency f of oscillations, different patterns are observed inside each cell. For well defined f values, neighboring cells are observed to interact and a general organization is noticed. In such a situation, initially disordered structures lead to a general pattern covering the entire liquid pool and a spatial order appears all over the cell array.

description: Tangible Interaction in collaborative scenarios represents a natural und intuitive way to explore and discuss complex issues in a playful way, supporting communication, negotiation and teamwork. We present a concept for Elastic Displays to support decision-making processes in the context of civil engineering construction planning, related to the research context of Building Information modelling techniques. This involves the exploration of spatial issues, as well as identifying changes to the project schedule and cost plan. We use the power of Elastic Displays to quickly explore semantic and time layers in complex maps and uses them in conjunction with an integrated overview of the project timeline and cost overview. Furthermore, we discuss some gestures used for interacting with the Zoomable User Interface and navigate Layered Visualizations with magic lenses. Finally, we discuss our findings from the implemented prototype and share some thoughts on future work for Zoomable UIs on Elastic Displays.

description: Be-greifbare Interaktion vollzieht sich im Wesentlichen über die Manipulation physischer Objekte und durch den Einsatz des eigenen Körpers. Sie bezieht damit die Umgebung und den physischen Nutzungskontext in viel stärkerer Weise als rein grafische oder sprachbasierte Schnittstellen zur Steuerung von Mensch-Computer-Systemen ein. Die vielfältigen Möglichkeiten, Sensoren und Computersysteme in die Umwelt und ihre Gegenstände zu integrieren, bietet einen großen Gestaltungsspielraum. Das Forschungsfeld der »Be-greifbaren Interaktion« (Tangible Interaction) untersucht diesen Spielraum wissenschaftlich und praktisch, um sinnvolle und menschengerechte Anwendungen zu ermöglichen. Die Fachgruppe »Be-greifbare Interaktion« des GI-Fachbereichs Mensch-Computer-Interaktion bietet in ihrem gleichnamigen Workshop ein Forum zur Präsentation des wissenschaftlichen Diskurses und der interdisziplinären Auseinandersetzung mit den neuesten Entwicklungen und Forschungsergebnissen in diesem Forschungsfeld. Die Beitragsformen reichen dabei über theoretische, kritische und zukunftsweisende Reflexionen, bis hin zu gestalterischen Arbeiten und Studien, Berichte praktischer Umsetzungen und Systemdemonstrationen. Der Workshop öffnet die Diskussion für ein breiteres Fachpublikum, wobei aktuelle Entwicklungen und Fragestellungen offengelegt und neue Impulse für das Forschungsgebiet geschaffen werden.

description: In times of data-driven business, privacy and data protection are gaining importance. Users and legal bodies require the implementation of privacy-enhancing and transparencyenhancing technologies, such as privacy dashboards. Even though privacy dashboards contribute to privacy and data protection, they may also carry risks themselves. For example, privacy dashboards require access to and collection of quite a huge amount of personal data. This of course leads to a conflict with their primary goal—namely privacy, including data-minimization—and thus leads it ad absurdum. We particularly focus on privacy dashboards for employees as an example technology for transparency and self-determination at their workplace. Conflicts address among others transparency vs. data-minimization, and self-determination vs. social pressure. In this paper, we elaborate such conflicts and discuss corresponding solution strategies.

description: Digitale Assistenzsysteme unterstützen das sichere und selbstbestimmte Leben im eigenen Zuhause. Neben technischen Produktinnovationen, wie Sprachassistenten, bietet besonders die Vernetzung existierender Gesundheits- und Gebäudetechnik Potenziale, neue Dienste nutzerzentriert für Zielgruppen mit häufig geringer IT-Affinität zu entwickeln. Damit können sowohl Bewohner zum souveränen Selbstmanagement der eigenen Gesundheit und Sicherheit befähigt werden und gleichzeitig Gesundheitsdienstleistern wie Pflegediensten und Hausärzte engmaschige Daten aus dem täglichen Leben zur Verfügung gestellt werden. Bestehende (Öko-)Systemgrenzen und Insellösungen erschweren bisher die Schaffung von nutzerzentrierten offenen Lösungen für datenbasierte Innovation. Der Beitrag zeigt, ausgehend von dem Modellprojekt „Digitales Gesundheitsdorf“, wie zukünftig Systemgrenzen der Ambient Assisten Living (AAL)- und Smart-Home-Technologie überwunden werden können um neue nutzerzentrierte Dienste für ein sicheres und selbstbestimmtes Leben von Patienten und Bewohner in der häuslichen Umgebung zu entwickeln.

description: In 1991 the researchers at the center for the Learning Sciences of Carnegie Mellon University were confronted with the confusing question of “where is AI” from the users, who were interacting with AI but did not realize it. Three decades of research and we are still facing the same issue with the AItechnology users. In the lack of users’ awareness and mutual understanding of AI-enabled systems between designers and users, informal theories of the users about how a system works (“Folk theories”) become inevitable but can lead to misconceptions and ineffective interactions. To shape appropriate mental models of AI-based systems, explainable AI has been suggested by AI practitioners. However, a profound understanding of the current users’ perception of AI is still missing. In this study, we introduce the term “Perceived AI” as “AI defined from the perspective of its users”. We then present our preliminary results from deep-interviews with 50 AItechnology users, which provide a framework for our future research approach towards a better understanding of PAI and users’ folk theories.

description: Im Kontext von Industrie 4.0 werden gegenwärtig Möglichkeiten intelligenter Assistenzsysteme diskutiert, deren Einsatz große Chancen zur Steigerung der Produktivität manueller Tätigkeiten bedeuten könnte. Während diese Systeme große Chancen für die Unternehmen bieten, bedeuten sie für Arbeitnehmer*innen auch eine potenzielle Kontrolle und Überwachung. In diesem Positionsbeitrag wollen wir daher für eine partizipative Gestaltung solcher Systeme plädieren. Der vorliegende Beitrag beschreibt zunächst die Zusammenarbeit von Assistenzsystemen und Beschäftigten im industriellen Umfeld. Anschließend wird die Kontrolle und Überwachung von Mitarbeiter*innen betrachtet, zunächst im historischen Kontext, dann im aktuellen. Es wird aufgezeigt inwieweit Beschäftigte durch Assistenzsysteme überwacht beziehungsweise kontrolliert werden können. Im Spannungsfeld zwischen Effizienzsteigerung und Arbeitnehmer*innen-Interessen plädieren wir für die Einbeziehung von System-Nutzer*innen sowie weiteren Interessensvertretungen, wie z. B. Gewerkschaften, in den Entwicklungsprozess, damit ein ethisch vertretbarer Einsatz von Assistenzsystemen gelingen kann.

description: We present shadow spectroscopy as a simulator-agnostic quantum algorithm for estimating energy gaps using very few circuit repetitions (shots) and no extra resources (ancilla qubits) beyond performing time evolution and measurements. The approach builds on the fundamental feature that every observable property of a quantum system must evolve according to the same harmonic components: we can reveal them by post-processing classical shadows of time-evolved quantum states to extract a large number of time-periodic signals $N_o\propto 10^8$, whose frequencies correspond to Hamiltonian energy differences with Heisenberg-limited precision. We provide strong analytical guarantees that (a) quantum resources scale as $O(\log N_o)$, while the classical computational complexity is linear $O(N_o)$, (b) the signal-to-noise ratio increases with the number of processed signals as $\propto \sqrt{N_o}$, and (c) spectral peak positions are immune to reasonable levels of noise. We demonstrate our approach on model spin systems and the excited state conical intersection of molecular CH$_2$ and verify that our method is indeed intuitively easy to use in practice, robust against gate noise, amiable to a new type of algorithmic-error mitigation technique, and uses orders of magnitude fewer number of shots than typical near-term quantum algorithms -- as low as 10 shots per timestep is sufficient. Finally, we measured a high-quality, experimental shadow spectrum of a spin chain on readily-available IBM quantum computers, achieving the same precision as in noise-free simulations without using any advanced error mitigation, and verified scalability in tensor-network simulations of up to 100-qubit systems.

description: Machine Translation (MT) system generally aims at automatic representation of source language into target language retaining the originality of context using various Natural Language Processing (NLP) techniques. Among various NLP methods, Statistical Machine Translation(SMT). SMT uses probabilistic and statistical techniques to analyze information and conversion. This paper canvasses about the development of bilingual SMT models for translating English to fifteen low-resource Indian Languages (ILs) and vice versa. At the outset, all 15 languages are briefed with a short description related to our experimental need. Further, a detailed analysis of Samanantar and OPUS dataset for model building, along with standard benchmark dataset (Flores-200) for fine-tuning and testing, is done as a part of our experiment. Different preprocessing approaches are proposed in this paper to handle the noise of the dataset. To create the system, MOSES open-source SMT toolkit is explored. Distance reordering is utilized with the aim to understand the rules of grammar and context-dependent adjustments through a phrase reordering categorization framework. In our experiment, the quality of the translation is evaluated using standard metrics such as BLEU, METEOR, and RIBES

description: Vibro-tactile navigation systems use the sense of touch across numerous application contexts and motivations. The vibrotactile patterns (tactons) deployed to transmit the information are often tailored to the scenario and the respective hardware. Without an appropriate classification system, it is difficult to compare tactons with each other or to identify their potential for new use cases. Therefore, we apply the previously developed taxonomy VibTacX to a set of tactons used for navigation tasks – NAVIGONS. Following, we present and discuss the identified characteristics of the use cases. Furthermore, the application of VibTacX acts as a filter system to identify and investigate similarities and differences independent of the use cases. This procedure may be the basis for the structured development of tactons. Hence, we conclude with an outlook on future design guidelines for vibro-tactile user interfaces and the qualitative improvement of tactons.
Atomistic simulations of twin boundary effect on the crack growth behaviour in BCC Fe

description: In this paper, the effect of twin boundaries on the crack growth behaviour of single crystal BCC Fe has been investigated using molecular dynamics simulations. The growth of an atomically sharp crack with an orientation of (111)$$ (crack plane/crack front) has been studied under mode-I loading at constant strain rate. In order to study the influence of twin boundaries on the crack growth behaviour, single and multiple twin boundaries were introduced perpendicular to crack growth direction. The results indicate that the (111)$$ crack in single crystal BCC Fe grows in brittle manner. However, following the introduction of twin boundaries, a noticeable plastic deformation has been observed at the crack tip. Further, increasing the number of twin boundaries increased the amount of plastic deformation leading to better crack resistance and high failure strains. Finally, an interesting relationship has been observed between the crack growth rate and flow stress.

description: In this paper, we explore the tokenized representation of musical scores using the Transformer model to automatically generate musical scores. Thus far, sequence models have yielded fruitful results with note-level (MIDI-equivalent) symbolic representations of music. Although the note-level representations can comprise sufficient information to reproduce music aurally, they cannot contain adequate information to represent music visually in terms of notation. Musical scores contain various musical symbols (e.g., clef, key signature, and notes) and attributes (e.g., stem direction, beam, and tie) that enable us to visually comprehend musical content. However, automated estimation of these elements has yet to be comprehensively addressed. In this paper, we first design score token representation corresponding to the various musical elements. We then train the Transformer model to transcribe note-level representation into appropriate music notation. Evaluations of popular piano scores show that the proposed method significantly outperforms existing methods on all 12 musical aspects that were investigated. We also explore an effective notation-level token representation to work with the model and determine that our proposed representation produces the steadiest results.

description: Human activities can play a crucial role in the statistical properties of observables in many complex systems such as social, technological and economic systems. We demonstrate this by looking into the heavy-tailed distributions of observables in fatal plane and car accidents. Their origin is examined and can be understood as stochastic processes that are related to human activities. Simple mathematical models are proposed to illustrate such processes and compared with empirical results obtained from existing databanks.

At what mass are stars braked? The implication from the turnoff morphology of NGC 6819

description: Extended main-sequence turnoffs apparent in most young and intermediate-age clusters (younger than ~2 Gyr) are known features caused by fast rotating early-type (earlier than F-type) stars. Late-type stars are not fast rotators because their initial angular momenta have been quickly dispersed due to magnetic braking. However, the mass limit below which stars have been magnetically braked has not been well constrained by observation. In this paper, we present an analysis of the eMSTO of NGC 6819, an open cluster of an intermediate-age (~2.5 Gyr), believed to be comparable to the lifetime of stars near the mass limit for magnetic braking. By comparing the observation with synthetic CMDs, we find that NGC 6819 does not harbor an obvious eMSTO. The morphology of its TO region can be readily explained by a simple stellar population considering the observational uncertainties as well as the differential reddening. In addition, the MSTO stars in NGC 6819 have very small values of average rotational velocity and dispersion, indicating that they have undergone significant magnetic braking. Combining with results in the literature for clusters of younger ages, our current work suggests that the critical age for the disappearance of eMSTO in star clusters must be shorter but very close to the age of NGC 6819, and this, in turn, implies a critical stellar mass for magnetic braking at solar metallicity above but close to 1.54 $M_{\odot}$ based on the PARSEC model. We emphasize that the phenomenon of eMSTO could provide a unique way to constrain the onset mass of magnetic braking.

description: In this work we investigate an influence of decoherence effects on quantum states generated as a result of the cross-Kerr nonlinear interaction between two modes. For Markovian losses (both photon loss and dephasing), a region of parameters when losses still do not lead to destruction of non-classicality is identified. We emphasize the difference in impact of losses in the process of state generation as opposed to those occurring in propagation channel. We show moreover, that correlated losses in modern realizations of schemes of large cross-Kerr nonlinearity might lead to enhancement of non-classicality.

description: Dendritic cells are the crime scene investigators of the human immune system. Their function is to correlate potentially anomalous invading entities with observed damage to the body. The detection of such invaders by dendritic cells results in the activation of the adaptive immune system, eventually leading to the removal of the invader from the host body. This mechanism has provided inspiration for the development of a novel bio-inspired algorithm, the Dendritic Cell Algorithm. This algorithm processes information at multiple levels of resolution, resulting in the creation of information granules of variable structure. In this chapter we examine the multi-faceted nature of immunology and how research in this field has shaped the function of the resulting Dendritic Cell Algorithm. A brief overview of the algorithm is given in combination with the details of the processes used for its development. The chapter is concluded with a discussion of the parallels between our understanding of the human immune system and how such knowledge influences the design of artificial immune systems.

Such two-dimensional necklace solitons appear as rings of multiple out-of-phase bright spots. We show that necklace solitons are stable if their peak intensity is low or moderate and that the domain of stability shrinks with increasing nonlinearity modulation depth. However, we find that the stability domains expand with increasing number of necklace spots.

description: Rational approximations of the matrix sign function lead to multishift methods. For non-Hermitian matrices long recurrences can cause storage problems, which can be circumvented with restarts. Together with deflation we obtain efficient iterative methods, as we show in numerical experiments for the overlap Dirac operator at non-vanishing quark chemical potential for lattices up to size 10^4.

description: As social VR applications become more commercially available, it is important to consider roles users take on in conversation to develop future guidelines for conversational VR interfaces. This position paper proposes that in order to design effective conversations on social VR platforms, conversational footing needs to be considered alongside rendering gaze, gesture, proxemics, and facial expression to systematically design for dynamic roles, as users engage in conversation. Through the consideration of roles such as speakers, addressees, by-standers, and overhearers, a framework for interaction can be developed for multi-user engagement. This paper highlights the lack of multi-user guidelines in VR and suggests incorporating design insights from experimental work and conversational analysis to systematically organize verbal and nonverbal cues for users through roles in multi-party environments.

description: The complete understanding of the formation of seemingly levitating droplets on liquid-repelling surfaces provides the basis for further development of applications requiring friction-free liquid transport. For the investigation of these droplets and, thereby, the underlying surface properties, standard techniques typically only reveal a fraction of droplet or surface information. Here, we propose to exploit the light-shaping features of liquid droplets when interpreted as thick biconvex elliptical lenses. This approach has the potential to decode a plethora of droplet information from a passing laser beam, by transforming the information into a structured light field. Here, we explore this potential by analyzing the three-dimensional intensity structures sculpted by the droplet lenses, revealing the transfer of the characteristics of the underlying liquid-repelling effect onto the light field. As illustrative complementary examples, we study droplet lenses formed on a non-wetting Taro (Colocasia esculenta) leaf surface and by the Leidenfrost effect on a heated plate. Our approach may reveal even typically "invisible" droplet properties as the refractive index or internal flow dynamics and, hence, will be of interest to augment conventional tools for droplet and surface investigation.

Temporal and spatial differences in movement of cutthroat trout in Placid Lake, British Columbia

description: The temporal and spatial variations in the activity of cutthroat trout in a small coastal British Columbia lake (49°19'N, 122°34’W) were examined in order to determine the Impact of activity on the production of fish, and the factors controlling activity. Sonar tracking, diving, netting and tagging, rise observation, stomach content-prey distribution comparision, and echo sounding were used in the Investigation. Average activity levels were at least an order of magnitude below any published values. Energy values were correspondingly low; the maximum estimate of annual energy expenditure in activity (including routine metabolism) was 2330 kCal/kg/yr, which is well below the accepted 'rule' of field metabolism being twice the routine metabolism (3860 kCal/kg/yr). Fish behavioral problems and methodological shortcomings are considered responsible for this result. Activity over 5 min intervals was quite variable. Daily activity peaked during dawn and dusk. The level of activity decreased in late fall and early spring, and there was a shift from the littoral zones during summer. The cutthroat in the lake appear to maintain home ranges-for up to 5 months. Factors affecting activity can be broken into 3 categories: Temperature, light, and oxygen primarily determine the depth zones that are accessible to fish. Substrates such as Potamogeton beds and logs may act to concentrate fish within accessible depth zones; attraction is likely due to the higher food levels and/or increased cover found in these areas. Bottom slope, by affecting foraging efficiency in the productive littoral areas, might also affect the summer offshore distribution of fish within an accessible depth zone. It is suggested that the indirect effects of activity (specifically, the offshore movement of fish in summer) can be equally or even more important to the production of fish than is the direct use of energy for activity. higher food levels and/or increased cover found in these areas.

description: Categorical attributes are those that can take a discrete set of values, e.g., colours. This work is about compressing vectors over categorical attributes to low-dimension discrete vectors. The current hash-based methods compressing vectors over categorical attributes to low-dimension discrete vectors do not provide any guarantee on the Hamming distances between the compressed representations. Here we present FSketch to create sketches for sparse categorical data and an estimator to estimate the pairwise Hamming distances among the uncompressed data only from their sketches. We claim that these sketches can be used in the usual data mining tasks in place of the original data without compromising the quality of the task. For that, we ensure that the sketches also are categorical, sparse, and the Hamming distance estimates are reasonably precise. Both the sketch construction and the Hamming distance estimation algorithms require just a single-pass; furthermore, changes to a data point can be incorporated into its sketch in an efficient manner. The compressibility depends upon how sparse the data is and is independent of the original dimension -- making our algorithm attractive for many real-life scenarios. Our claims are backed by rigorous theoretical analysis of the properties of FSketch and supplemented by extensive comparative evaluations with related algorithms on some real-world datasets. We show that FSketch is significantly faster, and the accuracy obtained by using its sketches are among the top for the standard unsupervised tasks of RMSE, clustering and similarity search.

description: To choose the best fitting UX questionnaire for a concrete evaluation project is far from being easy. There is a huge number of different UX questionnaires available. Each of them measures by its scales and items a subset of what we understand by the ill-defined concept of user experience. We analyze a sample of 40 established UX questionnaires and try to work out their differences and similarities. This analysis shows the heterogeneity of the field. In addition, we analyze how the current practice to develop new UX questionnaires adds to this inhomogeneity and lack of common understanding what we measure when we measure UX. Hopefully, this is a first step towards the development of a common framework that helps UX professionals to find their way through the jungle of available UX questionnaires and measurement concepts.

description: We have combined recent Hubble Space Telescope WFPC2 images in the [O III] 5007 and [N II] 6583 lines with similar images made 9.557 years earlier to determine the motion of the Ring Nebula within the plane of the sky. Scaled ratio images argue for homologous expansion, that is, larger velocities scale with increasing distance from the central star. The rather noisy pattern of motion of individual features argues for the same conclusion and that the silhouetted knots move at the same rate as the surrounding gas. These tangential velocities are combined with information from a recent high resolution radial velocity study to determine a dynamic distance, which is in basic agreement with the distance determined from the parallax of the central star. We have also obtained very high signal to noise ratio moderate resolution spectra (9.4 Angstrom) along the major and minor axes of the nebula and from this determined the electron temperatures and density in the multiple ionization zones present. These results confirm the status of the Ring Nebula as one of the older planetary nebulae, with a central star transitioning to the white dwarf cooling curve.
