    User Experience of Conveying Emotions by Touch2017Inngår i: Proceedings of the 26th IEEE International Symposium on Robot and Human Interactive Communication (RO-MAN), IEEE, 2017, s. 1240-1247Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In the present study, 64 users were asked to convey eight distinct emotion to a humanoid Nao robot via touch, and were then asked to evaluate their experiences of performing that task. Large differences between emotions were revealed. Users perceived conveying of positive/pro-social emotions as significantly easier than negative emotions, with love and disgust as the two extremes. When asked whether they would act differently towards a human, compared to the robot, the users’ replies varied. A content analysis of interviews revealed a generally positive user experience (UX) while interacting with the robot, but users also found the task challenging in several ways. Three major themes with impact on the UX emerged; responsiveness, robustness, and trickiness. The results are discussed in relation to a study of human-human affective tactile interaction, with implications for human-robot interaction (HRI) and design of social and affective robotics in particular.

    User Experience in Social Human-Robot Interaction2017Inngår i: International Journal of Ambient Computing and Intelligence (IJACI), ISSN 1941-6237, E-ISSN 1941-6245, Vol. 8, nr 2, s. 12-31Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Socially interactive robots are expected to have an increasing importance in human society. For social robots to provide long-term added value to people’s lives, it is of major importance to stressthe need for positive user experience (UX) of such robots. The human-centered view emphasizes various aspects that emerge in the interaction between humans and robots. However, a positive UX does not appear by itself but has to be designed for and evaluated systematically. In this paper, the focus is on the role and relevance of UX in human-robot interaction (HRI) and four trends concerning the role and relevance of UX related to socially interactive robots are identified, and three challenges related to its evaluation are also presented. It is argued that current research efforts and directions are not sufficient in HRI research, and that future research needs to further address interdisciplinary research in order to achieve long-term success of socially interactive robots.

    User experience of affective touch in human-robot interaction2015Inngår i: Proceedings of the 2015 SWECOG conference, Skövde: University of Skövde , 2015, s. 5-Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Robotic technology is quickly advancing and robots are entering both professional and domestic settings. An increased application of robots in elderly care and in therapy shows a shift towards social robots acting in human environments, designed to socially interact with humans. Socially interactive robots need to act in relation to social and emotional aspects of human life, and be able to sense and react to social cues. Touch, as one of the most fundamental aspects of human social interaction (Montagu, 1986) has lately received great interest in human-robot interaction (HRI) research (e.g. Dahiya et al., 2010; Silvera-Tawil et al., 2015) and the interpretation of touch in robotics has been presented as an unresolved research area with a crucial role in further development of HRI (Silvera-Tawil et al., 2015). It has been argued that the communicative distance between people and robots would be shortened and that the interaction would be more meaningful and intuitive if robots were able to “feel”, “understand”, and respond to touch in accordance with expectations of the human (Silvera-Tawil et al., 2015). However, this reasoning takes the notion of user experience (UX) for granted. The concept of UX embraces both pragmatic and hedonic aspects of interaction with technology in a particular context (Hartson & Pyla, 2012). In the field of human-computer interaction, UX has been acknowledged as a key term in the design of interactive products, but UX has not been emphasized in HRI. Accordingly, this research argues that it is important to study not only the robotic technology aspect of tactile interaction but also the user’s experience of the interaction, i.e. taking on the human-centered HRI approach presented by Dautenhahn (2007). Research on human-human interaction has showed that humans are able to communicate emotions via touch, and that specific emotions are associated with specific touch behaviors (Hertenstein et al., 2009). As a starting point for narrowing the distance between UX and HRI, the present research suggests a study where subjects are instructed to convey specific emotions to a humanoid robot. The study aims at investigating the role of affective touch in HRI with a focus on touch behaviors (e.g. stroking, grasping) for specific emotions, touch locations on the robot, and user experience of interacting with the robot via touch. The intended contributions of this study are an increased understanding of the necessary properties of tactile sensors enabling affective touch in human-robot interaction, the relevant placements of the sensors on the robot, and how the robot’s “look and feel” affects the user’s experience of the interaction. The proposed research embarks on a new track of HRI research and will, contrary to prior research on tactile interaction in HRI, emphasize the user experience of affective touch, highlighting that a positive user experience has to be systematically and consciously designed in order for the social robots to achieve the intended benefits of being socially interactive. Accordingly, the proposed study is believed to give new insights about the understudied dimension of UX in HRI, with the potential to enrich interaction between humans and social robots.

    Affective Touch in Human–Robot Interaction: Conveying Emotion to the Nao Robot2018Inngår i: International Journal of Social Robotics, ISSN 1875-4791, E-ISSN 1875-4805, Vol. 10, nr 4, s. 473-491Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Affective touch has a fundamental role in human development, social bonding, and for providing emotional support in interpersonal relationships. We present, what is to our knowledge, the first HRI study of tactile conveyance of both positive and negative emotions (affective touch) on the Nao robot, and based on an experimental set-up from a study of human–human tactile communication. In the present work, participants conveyed eight emotions to a small humanoid robot via touch. We found that female participants conveyed emotions for a longer time, using more varied interaction and touching more regions on the robot’s body, compared to male participants. Several differences between emotions were found such that emotions could be classified by the valence of the emotion conveyed, by combining touch amount and duration. Overall, these results show high agreement with those reported for human–human affective tactile communication and could also have impact on the design and placement of tactile sensors on humanoid robots.

    Past and Future Challenges for Railway Research and the Role of a Systems Perspective2019Inngår i: Proceedings of the 20th Congress of the International Ergonomics Association (IEA 2018): Volume VII: Ergonomics in Design, Design for All, Activity Theories for Work Analysis and Design, Affective Design / [ed] Sebastiano Bagnara, Riccardo Tartaglia, Sara Albolino, Thomas Alexander, Yushi Fujita, Cham: Springer, 2019, s. 1737-1746Kapittel i bok, del av antologi (Fagfellevurdert)
    Abstract [en]

    Operational train traffic is dependent on an efficient traffic plan monitored and executed by the traffic controllers, the proficient maneuvering of the trains by the train drivers, and on the interaction, communication, and coordination between these two work roles. The railway research community, and the branch of industry itself, has called for an integrated systems perspective for the whole train traffic system to achieve an efficient performance. As human-human and human-technology interactions are natural parts of the socio-technical system of train traffic, the aim of this paper is to provide illustrative examples for why a systems perspective is needed for the future of railway research. Furthermore, we present the theoretical framework of distributed cognition (DCog) as a necessary addition to the theoretical and methodological toolbox of the Human Factors and Ergonomics (HF&E) discipline. To realize efficient and coordinated processes involved in organizing and executing operational train traffic, the paper proposes that the DCog framework should be implemented in the train traffic domain as a viable approach forward.

    The coordination between train traffic controllers and train drivers: a distributed cognition perspective on railway2019Inngår i: Cognition, Technology & Work, ISSN 1435-5558, E-ISSN 1435-5566, Vol. 21, nr 3, s. 417-443Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Although there has long been a call for a holistic systems perspective to better understand real work in the complex domain of railway traffic, prior research has not strongly emphasised the socio-technical perspective. In operational railway traffic, the successful planning and execution of the traffic are the product of the socio-technical system comprised by both train drivers and traffic controllers. This paper presents a study inspired by cognitive ethnography with the aim to characterise the coordinating activities that are conducted by train traffic controllers and train drivers in the work practices of the socio-technical system of Swedish railway. The theoretical framework of distributed cognition (DCog) is used as a conceptual and analytical tool to make sense of the complex railway domain and the best practices as they are developed and performed “in the wild”. The analysis reveals a pattern of collaboration and coordination of actions among the workers and we introduce the concept of enacted actionable practices as a key concern for understanding how a successfully executed railway traffic emerges as a property of the socio-technical system. The implications for future railway research are briefly discussed.

    Distributed Cognition in Manufacturing: Collaborative Assembly Work2016Inngår i: Advances in Manufacturing Technology XXX / [ed] Yee Mey Goh, Keith Case, IOS Press, 2016, s. 243-248Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Cognitive science is becoming increasingly central within humanfactors and ergonomics (HF&E) and there has long been a call for a more systemicperspective in the area with a somewhat broader unit of analysis. This paperpresents a case study applying the theoretical framework of distributed cognition(DCog), which shows how DCog would offer a more complete understanding ofmanufacturing within its greater context, including the social, cultural, andmaterial surroundings. This paper aims to characterize and analyse dock assemblyof forest machines as a complex socio-technical system from a DCog perspective;focusing on the creation of enacted landscapes in this particular setting. The paperalso exemplifies benefits of using the DCog framework in the manufacturingdomain as a way of grasping the assembly workers’ tacit competence and skills.

    Interruptions in the wild: portraying the handling of interruptions in manufacturing from a distributed cognition lens2017Inngår i: Cognition, Technology & Work, ISSN 1435-5558, E-ISSN 1435-5566, Vol. 19, nr 1, s. 85-108Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper presents a study examining interruptionsin the wild by portraying the handling of interruptionsin manufacturing from a distributed cognitionlens. By studying how interruptions occur and are handledin the daily activities of a work team at a large foundry forcasting heavy diesel engines, we highlight situations whenthe propagation, transformation, and representation ofinformation are not supported by prescribed work processesand propose recommendations for how this can beamended. The study was conducted by several visits to theaforementioned factory with cognitive ethnography as thebasis for the data collection. The focus was on identifyinginterruptions and analysing these through a distributedcognition framework as an initial step towards studyinginterruptions in a manufacturing environment. The keyfindings include the identification of three, previouslyundefined, types of interruptions and the conclusion thatinterruptions do indeed affect the distributed workload ofthe socio-technical system and thus the overall productionperformance at the casting line.

    Tool use and collaborative work of dock assembly in practice2017Inngår i: Production & Manufacturing Research, ISSN 2169-3277, Vol. 5, nr 1, s. 164-190Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In order to deepen the understanding of the intrinsic interactions andinterplay between humans, tools, and environment from a systemsperspective, research in the wild (RITW) approaches have gainedtraction during recent decades as they provide a higher ecologicalvalidity of findings. This paper presents a RITW study, investigatinghow assembly, in this case dock assembly of forwarders, was donein practice. As our theoretical foundation, we used the framework ofdistributed cognition, which is one of the main pillars of RITW. Thefindings are presented in narrative form, describing and highlightingthat the workers achieve an efficient production outcome by beingintegral parts of the whole production process and doing so throughcoordination of activities benefitting the shared goal of the distributedsocio-technical system.

    Towards an increased degree of usability work in organizations2015Inngår i: Procedia Manufacturing, ISSN 2351-9789, Vol. 3, s. 5739-5746Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    It is widely recognized that there is a substantial gap between usability research and practice where UCD approaches are rarelyapplied in practice due to arguments regarding the intricate nature of its methods and techniques. This paper presents an actionresearch study designed to investigate and analyze the potentials for an increased degree of UCD activities in the earlydevelopment phases of advanced information systems technology. The results demonstrate that there is a large interest inusability but that organizational priority and competence is often lacking. Instead one relies heavily on questionable conceptssuch as „trained professionals‟ to excuse the low effort towards usability. Based on the results, six recommendations forimproved usability work in R&D organizations are presented, focusing on the importance of prioritization of, and education inusability work.

    Effects of Visualizing Missing Data: An Empirical Evaluation2014Inngår i: 18th International Conference on Information Visualisation (IV) / [ed] Ebad Banissi, Mark W. McK. Bannatyne, Francis T. Marchese, Muhammad Sarfraz, Anna Ursyn, Gilles Venturini, Theodor G. Wyeld, Urska Cvek, Marjan Trutschl, Georges Grinstein, Vladimir Geroimenko, Sarah Kenderdine & Fatma Bouali, IEEE conference proceedings, 2014, s. 132-138Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper presents an empirical study that evaluates the effects of visualizing missing data on decision-making tasks. A comparison between three visualization techniques: (1) emptiness, (2) fuzziness, and (3) emptiness plus explanation, revealed that the latter technique induced significantly higher degree of decision-confidence than the visualization technique fuzziness. Moreover, emptiness plus explanation yield the highest number of risky choices of the three. This result suggests that uncertainty visualization techniques affect the decision-maker and the decisionconfidence. Additionally, the results indicate a possible relation between the degree of decision-confidence and the decision-maker's displayed risk behavior.

    Current Challenges for UX Evaluation of Human-Robot Interaction2016Inngår i: Advances in Ergonomics of Manufacturing: Managing the Enterprise of the Future: Proceedings of the AHFE 2016 International Conference on Human Aspects of Advanced Manufacturing, July 27-31, 2016, Walt Disney World®, Florida, USA / [ed] Christopher Schlick and Stefan Trzcieliński, Switzerland: Springer, 2016, s. 267-277Kapittel i bok, del av antologi (Fagfellevurdert)
    Abstract [en]

    The development of socially interactive robots is expected to have anincreasing importance in everyday life for a growing number of people. For social robots to provide long-term added value to people’s lives, it is of major importanceto stress the need for developing a positive user experience (UX). The human-centered view emphasizes various aspects including acceptance, usability,and credibility, as they emerge in the interaction between humans and robots. In current human-robot interaction (HRI) research, UX is reckoned to be important,but is often taken for granted. However, a positive user experience does not appearby itself but has to be systematically designed and evaluated. In this paper, we focus on the role and relevance of UX in HRI and present three challenges related to the evaluation of UX in interaction with robots, addressing the need for interdisciplinary research in order to achieve long-term success of socially interactive robots.

    Designing for a Wearable Affective Interface for the NAO Robot: A Study of Emotion Conveyance by Touch2018Inngår i: Multimodal Technologies and Interaction, ISSN 2414-4088, Vol. 2, nr 1Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We here present results and analysis from a study of affective tactile communication between human and humanoid robot (the NAO robot). In the present work, participants conveyed eight emotions to the NAO via touch. In this study, we sought to understand the potential for using a wearable affective (tactile) interface, or WAffI. The aims of our study were to address the following: (i) how emotions and affective states can be conveyed (encoded) to such a humanoid robot, (ii) what are the effects of dressing the NAO in the WAffI on emotion conveyance and (iii) what is the potential for decoding emotion and affective states. We found that subjects conveyed touch for longer duration and over more locations on the robot when the NAO was dressed with WAffI than when it was not. Our analysis illuminates ways by which affective valence, and separate emotions, might be decoded by a humanoid robot according to the different features of touch: intensity, duration, location, type. Finally, we discuss the types of sensors and their distribution as they may be embedded within the WAffI and that would likely benefit Human-NAO (and Human-Humanoid) interaction along the affective tactile dimension.

    CLAM – A method for cognitive load assessment in manufacturing2017Inngår i: Advances in Manufacturing Technology XXXI / [ed] Gao, J., El Souri, M., Keates, S., Amsterdam: IOS Press, 2017, Vol. 6, s. 114-119Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The increasing complexity and demands of assembly operations in manufacturing has been shown to lead to increased cognitive load in assembly workers. Previous work has outlined the complexity of an assembly worker’s situation both in terms of difficulty and speed of work and there have been a few attempts at creating frameworks and methods for understanding the key aspects of what creates increased cognitive load. This paper presents a tool for assessing cognitive load in manufacturing, primarily assembly. The paper presents the method and an accompanying tool as well as some insights derived from this method development. The intended contribution of the work is to make a difference in reducing the cognitive load of assembly workers on the shop floor, thus focusing the development on applicability and usability of the tool in practice.

    On the development of a method for cognitive load assessment in manufacturing2019Inngår i: Robotics and Computer-Integrated Manufacturing, ISSN 0736-5845, E-ISSN 1879-2537, Vol. 59, s. 252-266Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The increasing complexity and demands of assembly operations in manufacturing has been shown to lead to increased cognitive load in assembly workers. Previous work has outlined the complexity of an assembly worker's situation both in terms of difficulty and speed of work and there have been a few attempts at creating frameworks and methods for understanding the key aspects of what creates increased cognitive load. This paper presents the development of an analytic method, denoted CLAM (Cognitive Load Assessment for Manufacturing), and a tool for assessing cognitive load in manufacturing, primarily assembly. It outlines the journey of the development as well as discusses and problematizes relevant meta-methodological issues paired with method development. The intended contribution of the work is to make a difference in reducing the cognitive load of assembly workers on the shop floor, thus focusing the development on applicability and usability of the tool in practice. With this purpose in mind, focus of the method development has been on the practitioners, i.e. the method should not require any expert knowledge to be applied. The CLAM method and accompanying documentation such as a handbook containing instructions towards using the method and interpreting the results, is available in an online tool.
