Abstract. Understanding a worker's perspective when introducing robots at humans' workplaces is crucial to improve human-robot interaction in production environments. Taking a temporal perspective on workers' experiences with robots, we explored expectations and general attitudes as well as actual feelings and reflections regarding the deployment of robots in a semiconductor factory. To evoke reports on workers' experiences, we applied a narrative interview technique with 10 workers. To characterize the temporal transition of workers' experiences, we distinguished between three phases in the deployment process: expectations before the deployment of the robots, familiarization with the robots, and experienced consequences of working with the robots. We present characteristic experiences of each phase and describe how these experiences change over time regarding the perceived functional value of the robots, work organization, feelings, social environment, and attitudes. Overall, our research contributes leverage points towards a more positive experience of workers when deploying robots in a factory.

User Experience (UX) is a major concept in HCI and a variety of different UX definitions have been suggested within the scientific community. An ISO UX definition has been presented to standardize the term from an industry perspective. We introduce methods from formal logic in order to formalize and analyze the ISO UX definition with regard to consistency and ambiguities and present recommendations for an improved version. Although this kind of formalization is not common within the CHI community, we show that quasi-formal methods provide an alternative way of analyzing widely discussed HCI terms, such as UX, to deepen its understanding.

Experiences with technology often are described as exciting and outstanding, for instance, in relation to novel technologies at home or at work. In this article, we aim to complement this perspective by emphasizing people's mundane and ordinary experiences with technology, that is, unremarkable experiences happening in the background of people's attention. Based on our investigations of user experience in a semiconductor factory, we show how such ordinary experiences are substantial in workers' everyday interactions with technology, which are mainly shaped by repetitive activities and routines. However, current conceptions of user experience seem to overlook those mundane experiences and how they can contribute to positive experiences with technology, as well as work engagement in the factory. In this article, we describe how ordinary experiences can be understood and described to amend current user experience conceptions by discussing theoretical, methodological, and design consequences.
