- In this paper, we propose a reinforcement learning (RL) mechanism for social robots to select an action based on users' learning performance and social engagement. We applied this behavior selection mechanism to extend the emotion and memory model, which allows a robot to create a memory account of the user's emotional events and adapt its behavior based on the developed memory. We evaluated the model in a vocabulary-learning task at a school during a children's game involving robot interaction to see if the model results in maintaining engagement and improving vocabulary learning across the four different interaction sessions. Generally, we observed positive findings based on child vocabulary learning and sustaining social engagement during all sessions. Compared to the trends of a previous study, we observed a higher level of social engagement across sessions in terms of the duration of the user gaze toward the robot. For vocabulary retention, we saw similar trends in general but also showing high vocabulary retention across some sessions. The findings indicate the benefits of applying RL techniques that have a reward system based on multi-modal user signals or cues.

New interaction modes for rich panoramic live video experiences

- The possibilities of panoramic video are based on the capabilities of high-resolution digital video streams and higher bandwidth's opportunities to broadcast, stream and transfer large content across platforms. With these opportunities also come challenges such as how to focus on sub-parts of the video stream and interact with the content shown on a large screen. In this paper, we present studies of two different interaction modes with a large-scale panoramic video for live experiences; we focus on interactional challenges and explore if it is (1) possible to develop new interactional methods/ways of approaching this type of high-resolution content and (2) feasible for users to interact with the content in these new ways. We developed prototypes for two different interaction modes: an individual system on a mobile device, either a tablet or a mobile phone, for interacting with the content on the same and a non-touch gesture-based system for the home or small group interaction. We present pilot studies where we explore the possibilities and challenges with these two interaction modes for panoramic content.

Usability and interaction design - new challenges for the Scandinavian tradition

- Computer use and interaction possibilities are changing quickly, while use contexts and application types are radically broadening. Technology no longer consists of static tools belonging only to the workplace but permeates work on the move, homes and everyday lives. Pervasive technologies, augmented reality, small interfaces, tangible interfaces, etc. are dramatically changing the nature of HCI (human-computer interaction). We witness the creation of ad hoc configurations of large and small user interfaces. The new interfaces are moveable and used in changing locations and contexts; different tasks are done through a combination of specialized technologies. A wider repertoire of physical instruments is available than the keyboard and the mouse. Based on examples from recent research projects and a collage of concepts and solutions, we discuss how these recent developments challenge our understanding of usability and interaction design. In particular, we discuss how the Scandinavian tradition of user involvement in development is facing up with the challenges of new work and of non-work contexts. There is a tendency that much recent investigations into non-work settings get stuck in a divide between work on the one hand, and leisure, arts, and home on the other; between rationality on the hand, and emotion on the other. The Scandinavian tradition can be developed to embrace people's whole lives and transcend the dichotomies between work, rationality, etc. and their negations and a Scandinavian perspective should and could move the current co-determination framework outside of work.

Walking in the Jungle with a Machete : ICT Leaders' Perspectives on User-Centred Systems Design
- 2022
-

Tidskriftsartikel (refereegranskat)abstract
- Previous research has established that leaders in information and communication technology (ICT) are crucial for establishing a user-centred systems design perspective in ICT for work-related tasks. This paper therefore describes the perspectives of 18 ICT leaders in three kinds of leadership roles (managers, project leaders and specialists) in order to understand their views of user-centred systems design concerning ICT. It uses the concept of technological frames of reference to analyse three domains: technology-in-use, technology strategy and nature of technology. The results show that many specialists see user involvement as a critical factor in successfully establishing new information and communication technologies, but that these systems are currently built around the needs of management rather than end users. Looking forward, all three relevant social groups are optimistic about how ICT will become more user-centred and more strategically aligned in the future. However, changes in ICT are described as extremely energy-consuming and difficult – akin to ‘walking in the jungle with a machete’. Finally, we discuss the relevance of technological frames and present some implications for the successful establishment of user-centred system design as a perspective in organisations.

Making HCI theory work : an analysis of the use of activity theory in HCI research

- This paper reports a study of the use of activity theory in human-computer interaction (HCI) research. We analyse activity theory in HCI since its first appearance about 25 years ago. Through an analysis and meta-synthesis of 109 selected HCI activity theory papers, we created a taxonomy of 5 different ways of using activity theory: (1) analysing unique features, principles, and problematic aspects of the theory; (2) identifying domain-specific requirements for new theoretical tools; (3) developing new conceptual accounts of issues in the field of HCI; (4) guiding and supporting empirical analyses of HCI phenomena; and (5) providing new design illustrations, claims, and guidelines. We conclude that HCI researchers are not only users of imported theory, but also theory-makers who adapt and develop theory for different purposes.

Designing the user interface of the computer-based speech training system ARTUR based on early user tests
- 2006

Tidskriftsartikel (refereegranskat)abstract
- This study has been performed in order to evaluate a prototype for the human - computer interface of a computer-based speech training aid named ARTUR. The main feature of the aid is that it can give suggestions on how to improve articulations. Two user groups were involved: three children aged 9 - 14 with extensive experience of speech training with therapists and computers, and three children aged 6, with little or no prior experience of computer-based speech training. All children had general language disorders. The study indicates that the present interface is usable without prior training or instructions, even for the younger children, but that more motivational factors should be introduced. The granularity of the mesh that classifies mispronunciations was satisfactory, but the flexibility and level of detail of the feedback should be developed further.

References to personal experiences and scientific evidence during medical multi-disciplinary team meetings

Tidskriftsartikel (refereegranskat)abstract
- We present a field study of medical multi-disciplinary team meetings (MDTMs) where decisions are made concerning the diagnosis and treatment of patients suffering from diseases in the upper abdomen. The study shows how evidence is referred to during weekly team meetings; this evidence is related both to scientific studies and to personal experiences of similar cases. We focus on the conversations during the meetings, on the complicated nature of the cases and on the details in the discussions that led the meeting participants to refer to scientific evidence or previous cases. We identify possibilities for improving the use of already documented information from medical records, in order to identify clinically relevant similarities and to bring additional information into the treatment discussion.
