    Determinants of Smallholder Farmers’ Intention to Use Smartphones - Evidence
from Rural India
    (Informatik in der Land-, Forst- und Ernährungswirtschaft 2017, 2017) Landmann, Dirk; Lagerkvist, Carl Johan; Otter, Verena
    The introduction of smartphones in developing countries’ agriculture has been targeted by different projects of NGOs and governmental institutions mostly without respecting social norms, attitude, self-control and anticipated emotions. Based on the theory of planned behaviour primary survey data from 647 farmers was collected in the Bihar region in India. The data analysis was conducted by using factor analysis and linear regression models. The results show that the factors social norms, attitude, self-control as well as positive and negative anticipated emotions have positive influences on the intention to use a smartphone for agricultural purposes. Thereby, negative anticipated emotions related to failure do not overwhelm the other factors. These results provide interesting implications for NGOs, politicians and ICT service providers.

    Emotions in the Age of Automated Driving - Developing Use Cases for Empathic Cars
    (Mensch und Computer 2019 - Workshopband, 2019) Oehl, Michael; Ihme, Klas; Bosch, Esther; Pape, Anna-Antonia; Vukelić, Mathias; Braun, Michael
    Improving user experience of highly automated vehicles is key to increase their acceptance. One possibility to realize this is the design of empathic cars that are capable of assessing the emotional state of vehicle occupants and react to it accordingly by providing tailored support. At the moment, the central challenge is to derive relevant use cases as basis for the design of future empathic cars. Therefore, we propose a workshop that aims to bring together researchers and practitioners interested in affective computing, affective interfaces and automated driving as forum for the development of a roadmap towards empathic vehicles using design thinking methods. During the workshop, we will gain a common understanding of the central concepts and listen to impulse talks about current and recent projects on emotions during automated driving. Based on this, relevant use cases are generated in group work and discussed with the goal to identify potential research and knowledge gaps. Finally, a road map for research towards the realization of automated empathic cars is formulated from the results.

    It’s in Your Eyes: Which Facial Design is Best Suited to Let a Robot Express Emotions?
    (Mensch und Computer 2019 - Tagungsband, 2019) Pollmann, Kathrin; Tagalidou, Nektaria; Fronemann, Nora
    It has been shown that emotional expressiveness makes robots appear more lifelike and believable. However, the facial design of commercially available robots is currently often not sufficient to convey emotions. We developed five facial design variants for a humanoid robot which can be used to display basic emotions (happiness, anger, sadness, fear) using different cartoon-inspired design approaches. These design variants were put on the head of the Pepper robot in cartoon-style drawings and tested in a quantitative user study. The findings indicate that the design approach of presenting the eyes on a large display and omitting the mouth is best suited to convey emotions, especially happiness and anger. Future work will improve the designs for sadness and fear, develop new designs for additional emotions and further investigate the role of the mouth design for emotional expressiveness of the robot.

    Time related changes of affective dimensions and distinct emotions in the interaction with a tablet PC
    (i-com: Vol. 21, No. 3, 2022) Brandenburg, Stefan; Spang, Robert
    Examining peoples’ affect and emotions over time and their effects on peoples’ behavior are ongoing endeavors in human-computer-interaction (HCI) research. This paper reports an experiment in which participants watched either positive or negative film clips on a tablet PC to enter a positive or negative affective state. Successively, they accomplished four basic system interaction tasks like changing fonts of an app on the same device. Results show that, in line with previous studies, peoples’ general valence ratings quickly reverted to neutral when starting the task accomplishment. At the level of distinct positive emotions, participants’ ratings of hope, joy, and serenity decreased after watching negative film clips. Moreover, amusement, love, and serenity decreased during the interaction with the tablet PC. Amongst the negative emotions, only ratings of sadness increased after watching negative film clips and decreased again after the interaction. Also, participants in the positive film group were slower in executing one of the basic tasks than participants in the negative film group. The findings suggest that only few emotions may be causal for peoples’ ratings of general affect. Results also indicate that negative emotions may help people executing standard tasks, in contrast to positive emotions. Implications for HCI design and research are discussed.

    User Experience Is All There Is - Twenty Years of Designing Positive Experiences and Meaningful Technology
    (i-com: Vol. 20, No. 3, 2021) Hassenzahl, Marc; Burmester, Michael; Koller, Franz
    Twenty years ago, we published an article in the first issue of the i-com entitled “Usability ist nicht alles” (Burmester et al., 2002), that is, “Usability isn’t everything”. This was certainly a provocative title. For most German researchers and practitioners of Human-Computer Interaction (HCI) usability was all there is and all that was ever needed to guarantee humane technology. Back then, we profoundly disagreed. We were convinced that there is more to the quality of interactive technology than mere effectiveness and efficiency. Now, twenty years later it seems safe to say that we had a point. Let’s take this as an opportunity to take a brief and utterly anecdotal look back, to take stock of the current perspective on designing the (user) experience, as well as to discuss some future opportunities and challenges.
