Providing urgent and emergency care to migrant children is often hampered or delayed. Reasons for this are language barriers when children, and their care givers, don’t speak any of the languages commonly spoken in Switzerland, which include German, French, Italian, and English. By a participatory design process, we want to develop a novel image-ba...

Full-text available
We demonstrate that Mobile Remote Presence systems (MRP) aka telepresence robots can be successfully used in certain types of medical consultation such as consultation from a distance with residents of nursing homes. We argue that MRP afforded media richness also allows for supporting social connectedness during medically recommended isolation regi...
Article
Full-text available
We present a new paradigm to address the persistence of difficulties that people have in accessing and using information. Our idea consists of two main aspects: engaging wider society with usability and distributing the topic across disciplines. We claim that bad usability is a social justice issue. Primarily, we propose that usability should becom...
Article
More than ever, Information Science needs a coherent, powerful, integrated vision of itself and the value proposition it delivers in this Information Age. Complex and multifaceted uncertainties like pandemics and climate change do not yield to narrow or piecemeal solutions. Holistic visions of Information Science existed at our field's formation a...
Article
Full-text available
Interviews with nursing home residents and medical practitioners who used a telepresence robot aka mobile remote presence bot (MRP) for medical consultation suggest that consulting via MRP is viable option for certain types of consultations. Participants perceived communication via the MRP as generally positive and the interaction felt natural even...
Article
Full-text available
Mobile remote presence bots (MRP) have emerged as a potential way of addressing the “tyranny of distance” when having to attend meetings at far away locations. In this contribution we report on how we used an MRP to share with two cohorts of postgraduate students at a regional university the formal “conferencing” and the informal “mingling” that ta...
Article
Emergency medical situations are characterized by high physical, cognitive and mental demands on the paramedics on the ground. Studies suggest that crucial information such as treatments administered to patients is often documented retrospectively, during patient transport or once a patient is handed over to an emergency department. Information acc...

Article
Full-text available
We posit that the well-established interaction type "toolbox" currently providing the four interaction types Instructing, Conversing, Manipulating, and Exploring should be expanded to include a fifth interaction type, Responding, that accounts for user engagements in response to a system-initiated engagement request. This expansion reflects that in...
Article
Full-text available
There is growing interest in embodiment in information seeking, which we use as an opportunity to reconsider what we as designers of information interfaces aim for. While we have become quite good at developing interfaces that are effective at supporting specific needs or needs that have been rendered specific, we are still not good at providing in...

Pattern-recognition in scientific data is not only a computational problem but a human-observer problem as well. Human observation of - and interaction with - data visualization software can augment, select, interrupt and modify computational routines and facilitate processes of pattern and significant feature recognition for subsequent human analy...
Article
Full-text available
In this brief contribution we argue that an apparent dichotomy between information behavior seen as the behavior of individuals and their respective information styles and information behavior considered a social practice may be resolved by considering the under-researched corporeality of the human body aka embodiment which is a fundamental aspect...
Article
Full-text available
It is widely recognized that knowledge sharing and learning are most effective when occurring in an appropriate and supportive context. As a consequence when designing an educational process the context has to be carefully considered. Implementing 'situated learning' is straightforward in traditional apprenticeship models that inspired the communit...

Conference Paper
Full-text available
In an ideal world, physical museum artefacts could be touched, handled, examined and passed between interested viewers by hand. Unfortunately, this is not always possible – artefacts may be too fragile to handle or pass around, or groups of people with mutual interests in objects may not be in the same location. This can be problematic when attempt...

There are many situations in which physical interaction with real-world objects is not possible - for example, museums contain many objects or artefacts which are too fragile or expensive for the public to handle. Augmented Reality (AR) has the potential to offer an alternative in these situations, but most of our current interactions with virtual...
Article
Full-text available
Context-aware artifacts can be seen as an important class of socially adept technologies. In this paper, we focus on the fact that disregarding trivial notions of context, context-aware artifacts are far from being capable of recognizing situations. Similarly, we are not aware of any other technologies that are able to understand social settings in...
