The paper concludes with guidelines that help determine which presentation choose given situation

If a mobile computing device knows how it is positioned and oriented in relation to other devices nearby, then can provide enhanced support for multi-device multi-user interactions. Existing systems that position information computers are reliant on externally deployed infrastructure, such as beacons or sensors the environment. We introduce Relate system, which provides fine-grained relative co-located basis of peer-to-peer sensing, thus overcoming dependence any external infrastructure. The...

Gestures can offer an intuitive way to interact with a computer. In this paper, we investigate the question whether gesturing mobile phone help perform complex tasks involving two devices. We present results from user study, where asked participants spontaneously produce gestures their trigger set of different activities. investigated three conditions (device configurations): phone-to-phone, phone-to-tabletop, and public display. report on kinds observed as well feedback participants,...

Reproducibility is a cornerstone of science and thus for geographic research as well. However, studies in other disciplines such biology have shown that published work rarely reproducible. To assess the state reproducibility, specifically computational reproducibility (i.e. rerunning analysis paper using original code), research, we asked geoscientists about this topic three methods: survey (n = 146), interviews 9), focus group 5). We participants their understanding open reproducible (ORR),...

One of the most promising possibilities for supporting user interaction with public displays is use personal mobile phones. Furthermore, by utilising Bluetooth users should have capability to interact without incurring financial connectivity costs. However, despite relative maturity as a standard and its widespread adoption in today's phones, little exploration seems taken place this area - apparent significant potential. This paper describe findings an exploratory study involving our Hermes...

A strong movement towards openness has seized science. Open data and methods, open source software, Access, reviews, research platforms provide the legal technical solutions to new forms of publishing. However, publishing reproducible is still not common practice. Reasons include a lack incentives missing standardized infrastructure for providing material such as sets code together with scientific paper. Therefore we first study fundamentals existing approaches. On that basis, our key...

Abstract Social distancing is one of the key measures to lower infections during a pandemic. Pedestrian signage way achieve this by managing flow people reduce crowdedness. However, visual signs can clutter environment and might not be noticed pedestrians. In paper, we propose auditory displays for pedestrian flow. We developed implicit explicit sound signs, evaluated them in user study with 16 participants compared our results those reported signage. Our show that are as effective people....

Location information can be used to enhance interaction with mobile devices. While many location systems require instrumentation of the environment, we present a system that allows devices measure their spatial relations in true peer-to-peer fashion. The is based on custom sensor hardware implemented as USB dongle, and computes real-time. In extension this propose set spatialized widgets for incorporation user interface. use these illustrated number applications, showing how employed support...

Thrombolytic treatment for acute ischaemic stroke improves prognosis, although there is a risk of bleeding complications leading to early death/severe disability. Benefit from thrombolysis time dependent and must be administered within 4.5 hours onset symptoms, which presents unique challenges development tools support decision making patient understanding about treatment. Our aim was develop aid patient-specific clinical decision-making stroke, communication personalised information on...

'Safe spaces' have been at the core of participatory design (PD) in HCI. However, their characteristics, potential impact and what enables them are not yet fully understood. The present article presents a series insights derived from six-week long study with 19 young forced migrants (YFMs). We investigated factors which contributed to enable creation 'safe while developing digital services them. based our case on four main components such spaces: (i) ethics, (ii) reflective processes, (iii)...

In this paper, we describe a public navigation system which uses adaptive displays as directional signs. The are mounted to walls where they provide passersbys with information. Each sign is an autonomous, wirelessly networked digital connected central server. signs position-aware and able adapt their display content in accordance current position. Advantages of such include improved flexibility, dynamic adaptation ease setup maintenance.

Recognized evaluation strategies are essential to systematically advance a research field's state of the art. Pervasive and ubiquitous computing need such mature as discipline enable researchers objectively assess compare new techniques' contributions. Researchers have shown that evaluating systems can be difficult, so approaches tend subjective, piecemeal, or both. To ensure validity usability proposed won't compromised, must reach consensus on set standard methods for systems. Otherwise,...

Large displays are rapidly proliferating in public spaces, and could therefore be an attractive resource to support nomadic users such contexts, e. g. by providing additional screen real estate or augmenting services delivered through a mobile device.While previous work on combining devices has identified number of benefits this combination, it is not yet clear if will actually use system they do, why when.In paper, we present two initial user studies investigating factors relevant...

The use of wearable devices during running has become commonplace. Although there is ongoing research on interaction techniques for while running, the effects resulting interactions natural movement patterns have received little attention so far.
