Train traffic controllers are engaged in a remote control process, monitoring train paths, points, and signals and when necessary, reschedule the current traffic plan with respect to perturbations and disruptions. The remote control process includes two different time frames which in turn require two different ways of working: one in the form of planning ahead and the other in the form of acting directly on feedback from the monitoring system. The main task of the train drivers is to operate their trains by following signals and the current plan set by the traffic controllers. The importance of a well-functioning collaboration between train drivers and train traffic controllers has lately received interest in the Human Factors & Ergonomics (HF&E) research (e.g. Tschirner, Sandblad & Andersson, 2014). This has led to updated work strategies for the traffic controllers that can enable them to continuously re-plan the traffic by projecting the traffic situation instead of the previous strategy to identify and handle conflicts as they occur. The new strategy is called control by re-planning (Kauppi, Wikström, Sandblad, & Andersson, 2006) and Kauppi et al. describe that it supports the traffic controllers' need to plan ahead and works as an efficient tool for solving traffic conflicts.

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 ...

But representing will not go away; what is necessary is a different kind of model. I will outline an action based, pragmatist model of representing that avoids the family of problems of classic models, and show how representing emerges naturally and necessarily in the evolution of agents. As cognition and representing permeate everythingmental, so also do the consequences of this shift in models of representing.

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 humanhuman affective tactile interaction, with implications for human-robot interaction (HRI) and design of social and affective robotics in particular.

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.

As a consequence, the features and quality requirements on human–robot interaction will increase, comprising possibilities to communicate emotions, establishing a positive user experience, e.g., using touch. In this paper, the focus is on depicting how humans, as the users of robots, experience tactile emotional communication with the Nao Robot, as well as identifying aspects affecting the experience and touch behavior. A qualitative investigation was conducted as part of a larger experiment. The major findings consist of 15 different aspects that vary along one or more dimensions and how those influence the four dimensions of user experience that are present in the study, as well as the different parts of touch behavior of conveying emotions.

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.

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 setup 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.

This paper presents a RITW study, investigating how assembly, in this case dock assembly of forwarders, was done in practice. As our theoretical foundation, we used the framework of distributed cognition, which is one of the main pillars of RITW. The findings are presented in narrative form, describing and highlighting that the workers achieve an efficient production outcome by being integral parts of the whole production process and doing so through coordination of activities benefitting the shared goal of the distributed socio-technical system.

By studying how interruptions occur and are handled in the daily activities of a work team at a large foundry for casting heavy diesel engines, we highlight situations when the propagation, transformation, and representation of information are not supported by prescribed work processes and propose recommendations for how this can be amended. The study was conducted by several visits to the aforementioned factory with cognitive ethnography as the basis for the data collection. The focus was on identifying interruptions and analysing these through a distributed cognition framework as an initial step towards studying interruptions in a manufacturing environment. The key findings include the identification of three, previously undefined, types of interruptions and the conclusion that interruptions do indeed affect the distributed workload of the socio-technical system and thus the overall production performance at the casting line.

For social robots to provide long-term added value to people's lives, it is of major importance to stress the 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.

For social robots to provide long-term added value to people’s lives, it is of major importance to 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 appear by 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.

This paper presents an action research study designed to investigate and analyze the potentials for an increased degree of UCD activities in the early development phases of advanced information systems technology. The results demonstrate that there is a large interest in usability but that organizational priority and competence is often lacking. Instead one relies heavily on questionable concepts such as 'trained professionals' to excuse the low effort towards usability. Based on the results, six recommendations for improved usability work in R&D organizations are presented, focusing on the importance of prioritization of, and education in usability work.

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.
