- Recent years have introduced major shifts in scientific reporting and publishing. The scientific community, publishers, funding agencies, and the public expect research to adhere to principles of openness, reproducibility, replicability, and repeatability. However, studies have shown that scientists often have neither the right tools nor suitable support at their disposal to meet these modern science challenges. In fact, even the concrete expectations connected to these terms may be unclear and subject to field-specific, organizational, and personal interpretations. Based on a narrative literature review of work that defines characteristics of open science, reproducibility, replicability, and repeatability, as well as a review of recent work on researcher-centered requirements, we find that the bottom-up practices and needs of researchers contrast top-down expectations encoded in terms related to reproducibility and open science. We identify and define reproducibility as a central term that concerns the ease of access to scientific resources, as well as their completeness, to the degree required for efficiently and effectively interacting with scientific work. We hope that this characterization helps to create a mutual understanding across science stakeholders, in turn paving the way for suitable and stimulating environments, fit to address the challenges of modern science reporting and publishing.

- The ability of a robot to detect and join groups of people is of increasing importance in social contexts, and for the collaboration between teams of humans and robots. In this paper, we propose a framework, autonomous group interactions for robots (AGIR), that endows a robot with the ability to detect such groups while following the principles of F-formations. Using on-board sensors, this method accounts for a wide spectrum of different robot systems, ranging from autonomous service robots to telepresence robots. The presented framework detects individuals, estimates their position and orientation, detects groups, determines their F-formations, and is able to suggest a position for the robot to enter the social group. For evaluation, two simulation scenes were developed based on the standard real-world datasets. The 1st scene is built with 20 virtual agents (VAs) interacting in 7 different groups of varying sizes and 3 different formations. The 2nd scene is built with 36 VAs, positioned in 13 different groups of varying sizes and 6 different formations. A model of a Pepper robot is used in both simulated scenes in randomly generated different positions. The ability for the robot to estimate orientation, detect groups, and estimate F-formations at various locations is used to determine the validation of the approaches. The obtained results show a high accuracy within each of the simulated scenarios and demonstrates that the framework is able to work from an egocentric view with a robot in real time.

Potentials and Challenges in Students’ Meaning-Making via Sign Systems

- The relationship between sign systems and the meaning potentials and affordances of multimodal technologies has received increasing attention in research on digital technology use in education. Students constantly adhere to and engage with semiotic shifts in sign systems when they work with digital technologies for learning purposes. This study explores students’ use of digital technologies in Swedish schools. We trace the way semiotic activity systems and cognitive processes are transformed and realized when students engage with shifts in sign systems into various meaning-making strategies. Methodologically, the study is based on a data set of video recordings, interviews, and observations of classroom practice in three primary schools. An analysis that draws on quantitative ethnography was applied to process and analyse the data. The main findings revealed that sign systems prompted by the technologies and the social space compete to some extent for students’ attention, and that technology design is monotonously rendering lower levels of mediation. These findings show that various sign system prompts need to be balanced and streamlined to support students in their meaning-making. This article conveys the importance of understanding sign systems, as they are the most common resources for technology-assisted learning, and change the prerequisites for meaning-making.

Customizing and Evaluating Accessible Multisensory Music Experiences with Pre-Verbal Children : A Case Study on the Perception of Musical Haptics Using Participatory Design with Proxies

Tidskriftsartikel (refereegranskat)abstract
- Research on Accessible Digital Musical Instruments (ADMIs) has highlighted the need for participatory design methods, i.e., to actively include users as co-designers and informants in the design process. However, very little work has explored how pre-verbal children with Profound and Multiple Disabilities (PMLD) can be involved in such processes. In this paper, we apply in-depth qualitative and mixed methodologies in a case study with four students with PMLD. Using Participatory Design with Proxies (PDwP), we assess how these students can be involved in the customization and evaluation of the design of a multisensory music experience intended for a large-scale ADMI. Results from an experiment focused on communication of musical haptics highlighted the diversity in employed interaction strategies used by the children, accessibility limitations of the current multisensory experience design, and the importance of using a multifaceted variety of qualitative and quantitative methods to arrive at more informed conclusions when applying a design with proxies methodology.
