Work-in-Progress: Effects of Attention Guidance on Virtual Reality Training for an Industrial Assembly Task
(2023)2023 Proceedings of the 9th International Conference of the Immersive Learning Research Network (iLRN 2023) Posters & Doctoral ColloquiumOne of the main objectives of Virtual Training Environments (VTEs) for industrial training is to train workers for a real world task. Prior work identified a multitude of factors influencing a VTE’s effectiveness. In this work-in-progress paper, we add to this body of research by evaluating the effect of attention guidance (AG) on a VTE’s effectiveness. In a controlled between-subject design pilot study with 42 participants, participants ...Conference Paper -
Condition-based Maintenance: Model vs. Statistics A Performance Comparison
(2016)Procedia CIRP ~ Factories of the Future in the digital environment - Proceedings of the 49th CIRP Conference on Manufacturing SystemsThe current development in industrial applications shows a variety of approaches to perform maintenance: With reactive maintenance, only parts which fail will be replaced. This causes high costs and high unexpected failure rates. Preventive maintenance uses a predefined service plan and also a wear part exchange schedule. The plan or schedule is often based on real-time or an operation time. This often results in fixed maintenance cycles ...Conference Paper -
Virtual reality based time and motion study with support for real walking
(2016)Procedia CIRP ~ Factories of the Future in the digital environment - Proceedings of the 49th CIRP Conference on Manufacturing SystemsManual operations in mass production are important cost drivers. Thus, tools like the MTM (Methods-time Measurement) – a time and motion study method – were introduced, which are nowadays established in industry for evaluation and improvement of production facilities. In this method, cardboard engineering is used to build simplified physical mock-ups of machines or production lines, in which the manual working process can be simulated. ...Conference Paper -
Data driven value creation in AEC along the building lifecycle
(2019)Journal of Physics: Conference SeriesInterest in the field of data analytics among researchers and practitioners has been rising over the last few years. The digitalization of the built environment leads to increased availability of data, enabling the introduction of data analytics. In this paper we propose a novel framework for data driven value creation in architecture, engineering and construction (AEC). The framework consists of four value creating categories, which are ...Conference Paper -
Integrating pointing gesture detection for enhancing brainstorming meetings using kinect and PixelSense
(2014)Procedia CIRP ~ 8th International Conference on Digital Enterprise Technology - DET 2014 Disruptive Innovation in Manufacturing Engineering towards the 4th Industrial RevolutionMicrosoft PixelSense is able to detect multitouch input and tagged objects as well, which makes it suitable to be used in net-based brainstorming sessions within small teams. However, any gestures above the table cannot be detected, which makes net-based brainstorming sessions less intuitive. Thus, we present a solution how Kinect can be used together with PixelSense to overcome this limitation without interference between the two devices.Conference Paper -
Online Condition Monitoring Tool for Automated Machinery
(2017)Procedia CIRP ~ 16th CIRP Conference on Modelling of Machining OperationsIn order to increase machinery resource, energy and time efficiency, Condition Monitoring (CM) offers a wide set of beneficial tools. Those tools can basically be segmented in maintenance improvements or the optimization of process parameters. CM requires data input from a component, which is then analyzed using data based or physical models, which return an estimate of the component_s current condition. The use of high quality sensors ...Conference Paper -
Efficient motion analysis of IT support for information retrieval at manual workplaces
(2019)Procedia CIRP ~ 12th CIRP Conference on Intelligent Computation in Manufacturing EngineeringWithin the context of the “Industrie 4.0” initiative, workers should be enabled by information technologies to extend their abilities to handle a wider range of work processes. However, such information technology also requires additional workload, which is not clearly measurable yet. This paper thus introduces a concept of an extended application of the MTM method to measure and analyze the information retrieval phase and to also provide ...Conference Paper -
Real walking in virtual environments for factory planning and evaluation
(2016)Procedia CIRP ~ 6th CIRP Conference on Assembly Technologies and Systems (CATS)Nowadays, buildings or production facilities are designed using specialized design software and building information modeling tools help to evaluate the resulting virtual mock-up. However, with current, primarily desktop based tools it is hard to evaluate human factors of such a design, for instance spatial constraints for workforces. This paper presents a new tool for factory planning and evaluation based on virtual reality that allows ...Conference Paper -
Virtual Navigation Environment for Blind and Low Vision People
(2018)LNCS ~ Computers Helping People with Special Needs. 6th International Conference, ICCHP 2018, Linz, Austria, July 11-13, 2018, Proceedings, Part IIFor comprehensively participating in society, independent and safe mobility is an important skill for many daily activities. Spatial cognition is one of the most important human capabilities and addresses the acquisition, processing and utilization of knowledge about the spatial layout of environments. Humans predominantly use the visual sense for this and for blind and low vision people, the lack of spatial perception reduces their quality ...Conference Paper -
Human-Robot Collaboration in Decentralized Manufacturing Systems: An Approach for Simulation-based Evaluation of Future Intelligent Production
(2017)Procedia CRIPThe development towards decentralized manufacturing systems aims at increased flexibility and robustness by maintaining the level of productivity. In order to meet these requirements, human-robot collaboration is considered as basic framework within future intelligent manufacturing cells. For industrial implementation, the concepts of smart production need to be refined and their benefits have to be quantified. This paper introduces ...Conference Paper
