The collection and use of real-time position data of logistics, tools and load carriers are already standard procedure in entire branches of the industry today. In addition to asset tracking, the technologies used also offer new possibilities for collecting and evaluating position and biometric data of employees. Thus, these technologies can be used for monitoring performance or for tracking worker behaviour, which can lead to additional burdens and stress for employees. In this context, the collection and evaluation of employee data can influence the workplace of the affected employee in the company to his or her disadvantage. The approach of Privacy by Design can help to benefit from all the advantages of these systems, while ensuring that the impact on employee privacy is kept to a minimum. Currently, there is no survey available that reviews tracking and tracing systems supporting this important and emerging field. This work provides a systematic overview from the perspective of the impact on employee privacy. Additionally, this paper identifies and evaluates the techniques used with regard to employee privacy in industrial tracking and tracing systems. This helps to reveal new privacy preserving techniques that are currently underrepresented, therefore enabling new research opportunities in the industrial community.}, language = {en}, number = {13}, urldate = {2021-08-04}, journal = {Sensors}, author = {Jandl, Christian and Wagner, Markus and Moser, Thomas and Schlund, Sebastian}, month = jun, year = {2021}, keywords = {Forschungsgruppe Digital Technologies, Institut für Creative Media Technologies, Smart Manufacturing, Wiss.

However, the restrictive structure of this top-down approach implying that upper level decisions are the constraints for lower level decisions also has its shortcomings. One problem that occurs is that deterministic mixed integer decision problems are often used for long-term planning, but the real production system faces a set of stochastic influences. Therefore, a planned utilisation factor has to be included into this deterministic aggregate planning problem. In practice, this decision is often based on past data and not consciously taken. In this paper, the effect of long-term forecast error on the optimal planned utilisation factor is evaluated for a production system facing stochastic demand and the benefit of exploiting this decision’s potential is discussed. Overall costs including capacity, backorder and inventory costs, are determined with simulation for different multi-stage and multi-item production system structures. The results show that the planned utilisation factor used in the aggregate planning problem has a high influence on optimal costs.

DESIGN: Case-control study. SETTING: MS day care center. PARTICIPANTS: Individuals with MS (n=28) and controls (n=28) (N=56). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Perceived muscular effort during dynamic elbow extensions was rated at 9 different weight intensities (10\%-90\% of 1-repetition maximum) in a single-blind, randomized order using the OMNI-Resistance Exercise Scale. Muscle activity of the triceps brachii muscle (lateral head) was measured via surface electromyography and normalized to maximal voluntary excitation. RESULTS: According to OMNI-level ratings, significant main effects were found for the diagnostic condition (F=27.33, P{\textless}.001, η(2)=.11), indicating 0.7 (95\% confidence interval [CI], 0.3-1.1) lower mean OMNI-level ratings for MS, and for the intensity level (F=46.81, P{\textless}.001, η(2)=.46), showing increased OMNI-level ratings for increased intensity levels for both groups. Furthermore, significant main effects were found for the diagnostic condition (F=16.52, P{\textless}.001, η(2)=.07), indicating 7.1\% (95\% CI, -8.6 to 22.8) higher maximal voluntary excitation values for MS, and for the intensity level (F=33.09, P{\textless}.001, η(2)=.36), showing higher relative muscle activities for increasing intensity levels in both groups. CONCLUSIONS: Similar to controls, individuals with MS were able to differentiate between different intensities of weight during dynamic elbow extensions when provided in a single-blind, randomized order. Therefore, perceived muscular effort might be considered to control resistance training intensities in individuals with MS. However, training intensity for individuals with MS should be chosen at approximately 1 OMNI level lower than recommended, at least for dynamic elbow extension exercises.}, language = {eng}, number = {2}, journal = {Archives of Physical Medicine and Rehabilitation}, author = {Heller, Mario and Retzl, Irene and Kiselka, Anita and Greisberger, Andrea}, month = feb, year = {2016}, pmid = {26525526}, keywords = {Center for Digital Health Innovation, Forschungsgruppe Digital Technologies, Studiengang Physiotherapie, best, best-lbheller}, pages = {252--258}, } @inproceedings{rind_user_2014, series = {{BELIV} '14}, title = {User {Tasks} for {Evaluation}: {Untangling} the {Terminology} {Throughout} {Visualization} {Design} and {Development}}, isbn = {978-1-4503-3209-5}, url = {http://publik.tuwien.ac.at/files/PubDat_232654.pdf}, doi = {10/f3szvm}, abstract = {User tasks play a pivotal role in evaluation throughout visualization design and development.

For the problem of assigning work packages to multi-skilled human resources with heterogeneous skills, the uncertainty on work package processing times is addressed. In the case where the required capacity exceeds the available capacity of internal resources, external human resources are used. The objective is to minimize the expected external costs. The first solution approach is a “matheuristic” based on a decomposition of the problem into a project scheduling subproblem and a staffing subproblem. An iterated local search procedure determines the project schedules, while the staffing subproblem is solved by means of the Frank–Wolfe algorithm for convex optimization. The second solution approach is sample average approximation where, based on sampled scenarios, the deterministic equivalent problem is solved through mixed-integer programming.

To facilitate the interpretation and analysis of APTs, we present SEQUIN, a grammar inference system based on the Sequitur compression algorithm that constructs a context-free grammar (CFG) from string-based input data. In addition to recursive rule extraction, we expanded the procedure through automated assessment routines capable of dealing with multiple input sources and types. This automated assessment enables the accurate identification of interesting frequent or anomalous patterns in sequential corpora of arbitrary quantity and origin.

Control of resistance training intensity based on perceived muscular effort is applicable to healthy individuals, yet there is no evidence of its utility for MS patients. OBJECTIVE: To compare perception of muscular effort in MS patients to healthy controls. METHODS: Based on their perception of muscular effort, twenty-five MS patients and twenty-eight controls adjusted static elbow extension tasks according to five levels on the OMNI-Resistance Exercise Scale. Elbow extension strength and muscle activity were measured via load cell dynamometer and surface electromyography (EMG) and related to each participant's maximal voluntary contraction (MVC) strength and muscle activity. Two-way analysis of variance was used to evaluate statistical significance. RESULTS: There were no statistically significant differences between MS patients and healthy controls, they produced similar relative torque values (F1 = 0.196; p {\textgreater} 0.05) and extensor muscle activities (F(2,617) = 1.556; p {\textgreater} 0.05) across all effort levels. CONCLUSION: No differences were found in the perception of muscular effort in MS patients and the age-matched control group.

These assessments generate a vast amount of complex data which need to be interpreted in a short time period. We conducted a design study in cooperation with gait analysis experts to develop a novel Knowledge-Assisted Visual Analytics solution for clinical Gait analysis (KAVAGait). KAVAGait allows the clinician to store and inspect complex data derived during clinical gait analysis. The system incorporates innovative and interactive visual interface concepts, which were developed based on the needs of clinicians. Additionally, an explicit knowledge store (EKS) allows externalization and storage of implicit knowledge from clinicians. It makes this information available for others, supporting the process of data inspection and clinical decision making. We validated our system by conducting expert reviews, a user study, and a case study.

To this date, real walking with users immersed in virtual environments with head-mounted displays (HMDs) is either possible with treadmills or room-scale (overground) VR setups. Especially for the latter, there is a growing interest in applications for interactive gait training as they could allow for more self-paced and natural walking. This study investigated if walking in an overground VR environment has relevant effects on 3D gait biomechanics. A convenience sample of 21 healthy individuals underwent standard 3D gait analysis during four randomly assigned walking conditions: the real laboratory (RLab), a virtual laboratory resembling the real world (VRLab), a small version of the VRlab (VRLab−), and a version which is twice as long as the VRlab (VRLab+). To immerse the participants in the virtual environment we used a VR-HMD, which was operated wireless and calibrated in a way that the virtual labs would match the real-world. Walking speed and a single measure of gait kinematic variability (GaitSD) served as primary outcomes next to standard spatio-temporal parameters, their coefficients of variant (CV\%), kinematics, and kinetics. Briefly described, participants demonstrated a slower walking pattern (−0.09 ± 0.06 m/s) and small accompanying kinematic and kinetic changes. Participants also showed a markedly increased gait variability in lower extremity gait kinematics and spatio-temporal parameters. No differences were found between walking in VRLab+ vs. VRLab−. Most of the kinematic and kinetic differences were too small to be regarded as relevant, but increased kinematic variability (+57\%) along with increased percent double support time (+4\%), and increased step width variability (+38\%) indicate gait adaptions toward a more conservative or cautious gait due to instability induced by the VR environment. We suggest considering these effects in the design of VR-based overground training devices. Our study lays the foundation for upcoming developments in the field of VR-assisted gait rehabilitation as it describes how VR in overground walking scenarios impacts our gait pattern.

A rolling horizon information update approach is assumed where customers provide their forecasts for a predefined information horizon. In the basic situation, a MMFE (martingale model of forecast evolution) demand model is assumed where information updates are unbiased. This setting is extended to a situation where updates are biased, i.e., a forecast update does not necessarily imply an information improvement. Furthermore, the model is extended by a demand shifting behaviour, i.e., demands for certain periods may be shifted to other periods. For this practically motivated demand model, the forecast accuracy related to periods before delivery is calculated and a measure for production order accuracy is developed assuming a simplified material requirements planning structure. Finally, a correction method for reducing the negative effects of biased demand forecasts is introduced and its performance is evaluated based on simulation and real company data.}, language = {en}, urldate = {2023-05-24}, journal = {Simulation Modelling Practice and Theory}, author = {Altendorfer, Klaus and Felberbauer, Thomas}, month = may, year = {2023}, keywords = {2023, Case study, Department Medien und Digitale Technologien, Forecast accuracy, Forecast updates, Forschungsgruppe Digital Technologies, Institut für Creative Media Technologies, Material requirements planning, Open Access, Phaidra, Production planning, Publikationstyp Schriftpublikation, Simulation, best, peer\_reviewed}, pages = {102740}, } @inproceedings{iber_pilotstudie_2015, address = {FH St. Pölten}, title = {Pilotstudie zur sonifikationsgestützten {Ganganalyse}}, isbn = {987-3-86488-090-2}, abstract = {Verletzungs- oder krankheitsbedingte Beeinträchtigungen des Ganges stellen die physiotherapeutische Behandlung vor große Herausforderungen.

Über eine diagnostische Anwendung hinaus können sie auch den motorischen Lernprozess in der physiotherapeutischen Behandlung unterstützen. Eine akustische Darstellung des Abrollverhaltens erlaubt PatientInnen mögliche Abweichungen wahrzunehmen und ermöglicht folglich Eigenkontrolle und Eigenständigkeit beim Üben. Auf Grundlage dieser Rahmenbedingungen wurde ein Hardware-Prototyp bestehend aus einem Paar mit Sensoren ausgestatteter Schuhsohlen und einem Mikroprozessor mit BluetoothLE entwickelt, der Bewegungsdaten in Echtzeit an ein handelsübliches mobiles Endgerät schickt. Auf diesem werden die parametrisierten Daten in Echtzeit sonifiziert, d.h. als Klänge synthetisiert, und über Kopfhörer der PatientIn zugespielt. Dadurch erhält die PatientIn eine zusätzliche Rückmeldung zu seinem Gangmuster. In einer Pilotstudie wurden Sonifikationsvarianten entwickelt und nach einer Vorauswahl durch PhysiotherapeutInnen durch eine Gruppe gesunder ProbandInnen evaluiert. Darüber hinaus wurde der objektive Einfluss der Sonifikationen auf das Gangmuster anhand von Bewegungsdaten, die mit Druckmessplatten erhobenen wurden, verglichen.}, booktitle = {Forum {Medientechnik} - {Next} {Generation}, {New} {Ideas}}, publisher = {Verlag Werner Hülsbusch, Fachverlag für Medientechnik und -wirtschaft}, author = {Iber, Michael and Horsak, Brian and Bauer, Karin and Kiselka, Anita and Gorgas, Anna-Maria and Dlapka, Ronald and Doppler, Jakob}, year = {2015}, note = {Projekt: CARMA Projekt: DHLab}, keywords = {2015, Biomechanics, Center for Digital Health Innovation, DHLab, Department Gesundheit und Soziales, Department Medien und Digitale Technologien, Forschungsgruppe Digital Technologies, Forschungsgruppe Media Computing, Gait Analysis, Institut für Creative Media Technologies, Institut für Gesundheitswissenschaften, Publikationstyp Präsentation, Publikationstyp Schriftpublikation, Publikationstyp Vortrag, SP IGW Clinical \& Healthcare Research, Studiengang Physiotherapie, Wiss.

Typical estimates of joint loading using an inverse dynamic approach only account for net joint moments, not considering the potential role of muscular co-contraction. Therefore, the purpose of this study was to compare muscular co-contraction levels when walking with two different unstable shoe constructions (rocker-bottom and toning shoes) compared to walking with regular shoes. For each shoe condition, 12 healthy subjects walked with both, a regular shoe and with an unstable shoe at self-selected walking speed at a 10-m walkway. Surface EMG data of selected muscles were recorded and time normalized for calculating co-contraction indices (CCI) for opposing muscle groups. Results showed an increase of co-contraction primarily for vastii and gastrocnemius muscles for the first and second half of stance when walking with an unstable shoe construction. Therefore, when using an inverse dynamic approach to analyze joint loading differences between regular shoes and unstable shoes, one should be cautious in interpreting the data, as these methods base their estimates of joint moments upon the net joint torque.}, language = {ENG}, number = {25}, journal = {Journal of Electromyography and Kinesiology: Official Journal of the International Society of Electrophysiological Kinesiology}, author = {Horsak, Brian and Heller, Mario and Baca, Arnold}, year = {2015}, pmid = {25156445}, note = {Projekt: DHLab}, keywords = {Biomechanics, Center for Digital Health Innovation, DHLab, Department Gesundheit und Soziales, Forschungsgruppe Digital Technologies, Gait Analysis, Institut für Gesundheitswissenschaften, Publikationstyp Schriftpublikation, SP IGW Clinical \& Healthcare Research, Studiengang Physiotherapie, Wiss.
