    Proposal of an Intuitive Interface Structure for Ergonomics Evaluation Software2018In: Proceedings of the 20th Congress of the International Ergonomics Association (IEA 2018): Volume VIII: Ergonomics and Human Factors in Manufacturing, Agriculture, Building and Construction, Sustainable Development and Mining / [ed] Sebastiano Bagnara, Riccardo Tartaglia, Sara Albolino, Thomas Alexander, Yushi Fujita, Cham: Springer, 2018, Vol. 825, p. 289-300Conference paper (Refereed)
    Abstract [en]

    Nowadays, different technologies and software for ergonomics evaluations are gaining greater relevance in the field of ergonomics and production development. The tools allow users such as ergonomists and engineers to perform assessments of ergonomic conditions of work, both related to work simulated in digital human modelling (DHM) tools or based on recordings of work performed by real operators. Regardless of approach, there are many dimensions of data that needs to be processed and presented to the users.

    The users may have a range of different expectations and purposes from reading the data. Examples of situations are to: judge and compare different design solutions; analyse data in relation to anthropometric differences among subjects; investigate different body regions; assess data based on different time perspectives; and to perform assessments according to different types of ergonomics evaluation methods. The range of different expectations and purposes from reading the data increases the complexity of creating an interface that considers all the necessary tools and functions that the users require, while at the same time offer high usability.

    This paper focuses on the structural design of a flexible and intuitive interface for an ergonomics evaluation software that possesses the required tools and functions to analyse work situations from different perspectives, where the data input can be either from DHM tools or from real operators while performing work.

    Managing Interruptions in Manufacturing: Towards a Theoretical Framework for Interruptions in Manufacturing Assembly2016Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The effect of interruptions from ICT systems on assembly workers in manufacturing is examined in this thesis, as is how the risks of errors, increases in assembly time, increased cognitive load and resultant stress can be mitigated, as well as ensuring that important new information is acted upon. To these ends, a literature study was conducted, followed by two studies using an experimental approach in an environment that simulated a manufacturing assembly situation, and used tasks designed to be representative of manufacturing assembly tasks. The results of the literature study and the two studies are presented in four appended papers. The body of the thesis itself introduces similar material, and takes a step towards the creation of a theoretical framework that supports analysing the tasks and environments in question from a embodied and situated (DEEDS or 4E) viewpoint on cognition. This theoretical framework uses graphical representations similar to storyboards to support the analyst in maintaining an embodied and situated viewpoint during analyses of active tasks that require an examination of the interplay between brain, body, and environment. Supporting an embodied viewpoint during analysis has the purpose of facilitating the design of interruption coordination systems that take into account the embodied and situated nature of the tasks faced in manual tasks such as assembly in manufacturing.

    Situating interruptions in manufacturing assembly2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Interruptions have been studied extensively, with interruptions experiments where tasks performed on computers are interrupted by another task received on the same computer having receiving much of the focus. Additionally, many of the tasks used in existing research have been designed specifically to test the effect of interruptions on humans by making both the interrupting task and the task being interrupted quite difficult. The studies introduced here show that these commonly used tasks do not accurately represent some aspects of the manual tasks commonly performed by humans outside of laboratory experiments, with the experiments in this thesis focusing on manual tasks in assembly. A notable difference identified here is that interruptions in manual assembly tasks were seen to always contain a negotiation element, meaning that the person being interrupted could always modify to some extent when to respond to interruptions. Another central finding is that breakpoints for smart interruption systems need to be chosen using even more care than suggested by existing research because of an effect that can cause a notification to be completely missed when sent at a point that seemed opportune. This is due to apparent lulls in the activity containing preparation for the next action, or anticipation of action, using the Activity Theory (AT) terms used in the analysis of this effect. AT was identified as a useful tool for the analysis of manual assembly as it supports a hierarchical analysis of the activity and takes into account operator skill (task familiarity) in an easy to understand manner.AT was further used in an observational study where current approaches to interruption management were observed and explored. A surprising conclusion was that classical interruptions, as commonly defined, where one task is interrupted and another task must be completed before resuming the main (primary) task were exceedingly uncommon. This was found to be due to the high task familiarity (skill level) of the workers, the assembly activities being designed to minimise the risk of interruptions, and workers being trained to always finish the current operation before switching to another task. Workers did however engage in conversation and an interesting style of communication, dubbed ebb-and-flow style of negotiation, was identified. The differences between the results found in literature and the results of the studies were synthesised into a theoretical framework, or a collection of theories that work together to support the analysis of interruptions, and a visual support tool for the theoretical framework was created. This visual support tool, called an activity board both binds together the theories in a way that should make the theoretical framework easier to understand, and provides the beginnings of an analysis tool for interruption using the framework.

    Showing uncertainty in aircraft cockpits using icons2015In: Procedia Manufacturing, ISSN 2351-9789, Vol. 3, p. 2905-2912Article in journal (Refereed)
    Abstract [en]

    This paper examines an icon set designed for displaying uncertainty surrounding threat levels of an approaching object in anaircraft cockpit. This is done through an experiment that compares an icon set designed for this experiment with two icon setsfrom existing research that were tested in static laboratory conditions. The experiment used a flight simulator to simulate realisticflight conditions. The results showed that the icon set designed for this experiment was easier to read. Guidelines for the designof icons for displaying uncertainty are presented based on the results of the experiment.

    Classification of Collaboration Levels for Human-Robot Cooperation in Manufacturing2018In: Advances in Manufacturing Technology XXXII: Proceedings of the 16th International Conference on Manufacturing Research, incorporating the 33rd National Conference on Manufacturing Research, September 11–13, 2018,  University of Skövde, Sweden / [ed] Peter Thorvald, Keith Case, Amsterdam: IOS Press, 2018, p. 151-156Conference paper (Refereed)
    Abstract [en]

    Industry 4.0 aims to support the factory of the future, which involves increased amounts of information systems and new ways of using automation. One new usage is collaboration between human and industrial robot in manufacturing, with both partners sharing work on a single task. Supporting human-robot collaboration (HRC) requires understanding the requirements of HRC as well as the differences to existing approaches where the goal is more automation, such as in the case of self-driving cars. We propose a framework that we call levels of collaboration to support this, and posit that this framework supports a mental model conducive to the design of lines incorporating HRC.

    Foundation for a classification of collaboration levels for human-robot cooperation in manufacturing2019In: Production & Manufacturing Research, ISSN 2169-3277, Vol. 7, no 1, p. 448-471Article in journal (Refereed)
    Abstract [en]

    Industry 4.0 aims to support the factory of the future, involving increased use of information systems and new ways of using automation, such as collaboration where a robot and a human share work on a single task. We propose a classification of collaboration levels for Human-Robot collaboration (HRC) in manufacturing that we call levels of collaboration (LoC), formed to provide a conceptual model conducive to the design of assembly lines incorporating HRC. This paper aims to provide a more theoretical foundation for such a tool based on relevant theories from cognitive science and other perspectives of human-technology interaction, strengthening the validity and scientific rigour of the envisioned LoC tool. The main contributions consist of a theoretical grounding to motivate the transition from automation to collaboration, which are intended to facilitate expanding the LoC classification to support HRC, as well as an initial visualization of the LoC approach. Future work includes fully defining the LoC classification as well as operationalizing functionally different cooperation types. We conclude that collaboration is a means to an end, so collaboration is not entered for its own sake, and that collaboration differs fundamentally from more commonly used views where automation is the focus.

    Mind the body: How embodied cognition matters in manufacturing2015In: Procedia Manufacturing, ISSN 2351-9789, Vol. 3, p. 5184-5191Article in journal (Refereed)
    Abstract [en]

    Embodied cognition can provide human factors and applied ergonomics practitioners with better embodied cognition design principles. This paper investigates and analyzes observational video-recorded data from an experiment that simulated a manufacturing environment. The operator was interrupted during a primary assembly task via a handheld computing device which delivered different classes of notifications. The focus is on the embodied aspect of notifications in an active environment, and why one class of notifications called mediated notifications failed at a specific point previously thought to be suitable. Guidelines for analyzing tasks from an embodied cognition perspective that complements and expands traditional human factors and applied ergonomics approaches were developed and are included.

    Missing mediated interruptions in manual assembly: Critical aspects of breakpoint selection2017In: Applied Ergonomics, ISSN 0003-6870, E-ISSN 1872-9126, Vol. 61, p. 90-101Article in journal (Refereed)
    Abstract [en]

    The factory of the future aims to make manufacturing more effective and easily customisable, using advanced sensors and communications to support information management. In this paper, we examine how breakpoint selection during interruption management can fail, even when using recommendations for interruption management from existing research. We present an experiment based on prior work where mediated interruptions (i.e. smart interruptions that should interrupt at opportune moments) were missed by participants when sent at one of two pre-defined breakpoints. These breakpoints were selected based on existing research to minimise the cost of interruption, which can involve longer times to complete tasks as well as making errors on tasks. Missing mediated interruptions in this way was unexpected, and the prior study was not configured to measure this effect, which has led to the experiment detailed here. We strive to explore whether there is a risk of missing notifications when mediated interruptions are used, and how this is affected by breakpoint selection. This was investigated through an experiment that uses tasks and environments that simulate a manufacturing assembly facility.

    The results indicate that the effect exists, i.e. that participants miss significantly more notifications when interrupted at fine breakpoints than when interrupted at coarse breakpoints. An embodied cognition perspective was used for analysis of the tasks to understand the cause of the effect. This analysis shows that an overlap between “action” and “anticipation of action” can account for why participants miss notifications at fine breakpoints. Based on these findings, recommendations were developed for designing interruption systems that minimise the costs (errors and time) imposed by interruptions during assembly tasks in manufacturing.

    Context aware interruptions: Existing research and required research2014In: Advances in Cognitive Engineering and Neuroergonomics / [ed] Kay Stanney & Kelly S. Hale, AHFE , 2014, p. 260-272Conference paper (Refereed)
    Abstract [en]

    Companies in various fields are developing information systems that are supposed to show information in a context sensitive manner. This involves modifying user interfaces based on the current activity and location of the user. The research that exists for context aware, task aware, and location aware systems come mostly from research in the office environment and using stationary work computers using standard mouse and keyboard-operated systems. Other environments, such as manufacturing environments, have not received the same research attention, and therefore research is required to see whether existing theories and frameworks apply to the manufacturing domain. Adding to this, context aware systems are now being created for new classes of devices such as mobile and wearable devices, to be used in multiple domains. All this requires an investigation and validation of older research, and shows how the research of the basic human factors surrounding new devices and domains has fallen behind the development of the devices themselves. This paper examines shortly how recent changes advances in technology affect what is required from the field of interruption research, as well as what is needed to support other domains than the office environment.

    Coordinating the interruption of assembly workers in manufacturing2017In: Applied Ergonomics, ISSN 0003-6870, E-ISSN 1872-9126, Vol. 58, p. 361-371Article in journal (Refereed)
    Abstract [en]

    This paper examines how interruptions from information and communications technology systems affect errors and the time to complete tasks for assembly workers. Interruptions have previously been examined in laboratory experiments and office environments, but not much work has been performed in other authentic environments. This paper contains the results of an experiment that was performed in a simulated manufacturing assembly environment, which tested the effects of interruptions on a manual assembly task. The experiment used existing interruption coordination methods as a basis, and the results showed a difference in the effect of interruptions and interruption coordination between cognitively complex laboratory tasks and manual assembly tasks in an authentic environment. Most notably, the negative effects of interruptions delivered without consideration were smaller in this experiment. Based on these findings, recommendations were developed for designing interruption systems for minimizing the costs (errors and time) imposed by interruptions during assembly tasks in manufacturing.

    Embodied Interactions in Cognitive Manufacturing2020In: Advances in Neuroergonomics and Cognitive Engineering: Proceedings of the AHFE 2019 International Conference on Neuroergonomics and Cognitive Engineering, and the AHFE International Conference on Industrial Cognitive Ergonomics and Engineering Psychology, July 24-28, 2019, Washington D.C., USA / [ed] Hasan Ayaz, Springer, 2020, p. 419-426Conference paper (Refereed)
    Abstract [en]

    This paper presents a discussion on the role of embodied interaction with a basis in social embodiment effects and how they can be viewed in light of manufacturing ergonomics. The social embodiment effects are four statements, grounded in empirical findings, which highlight the interplay of social stimuli, embodied responses, and cognitive processing. They suggest and base an argument for how embodiment is central to cognitive processing, how bodily states interact extensively with cognitive states, and ultimately how embodied interaction is ubiquitous in human cognition. The paper further presents a view on how human based manufacturing can be studied in light of this argument, exploring other areas where social embodiment has been further researched, with an aim to suggest examples of where social embodiment effects might be found in manufacturing ergonomics and form a basis for future investigations.
