In Human-Computer Interaction (HCI) research, awareness for the relevance of diversity users is increasing. this work, we analyze whether articulated need more diversity-sensitive research led indeed to a higher consideration in HCI research. Based on comprehensive collection dimensions, present results quantitative content analysis articles accepted Proceedings Conference Human Factors Computing Systems 2006, 2011, and 2016. Results demonstrate how many intensively dimensions were...
This paper presents an explorative study investigating the applicability of speech-only interaction in everyday life elderly people. For purpose this we connected iPhone 4s including Siri application with a Bluetooth enabled headset. By pressing activation button on participants were able to directly access services via voice without using graphical user-interface (GUI).
The ring current, a key feature of Earth's magnetosphere, is enhanced during geomagnetic storms, posing risks to spacecraft through surface charging by 10-50 keV electrons. While extensively studied, accurately modeling storm-time current dynamics remains challenging.We show that existing models significantly overestimate the trapped population Earth’s night-side electron at energies between 10 and 50 storms compared satellite observations. Through analysis drift trajectories, we...
In this work, we identify influencing factors on modality choices of older adults. detail, investigated when and why adults prefer speech over touch interaction vice versa interacting with a mobile multimodal health wellbeing service. We conducted study 19 using application duration three to six weeks. Due long the were able gain highly external valid insights as our results are based real world experiences. additional within areas user characteristics, contextual perceived system...
Abstract The hazardous plasma environment surrounding Earth poses risks to satellites due internal charging and surface effects. Accurate predictions of these are crucial for minimizing damage preparing system failures satellites. To forecast the environment, it is essential know current state system, as accuracy depends on initial condition forecast. In this study, we use data assimilation techniques combine observational model predictions, present first global validation a...
Ring current particles, which are heavily influenced by geomagnetic activity, excite plasmawaves (e.g., EMIC, chorus etc) and affect the terrestrial magnetospheric configuration, modifies particle trajectories. During storms, specifically recovery phase, ring becomes disturbed decays via various loss processes charge exchange, Coulomb collisions, EMIC wave scattering). These disturbances in contribute significantly to development of Dst index. Since plays a crucial role dynamics through its...
Numerical models used to study the Earth’s outer radiation belt dynamics are often based on diffusive Fokker-Planck equation derived from quasilinear theory of wave-particle interactions. However, this stochastic approach fails at short time scales due nonlinear interactions with high-amplitude waves, which can result in a rapid directional transport particles phase space. An example strong waves that facilitate is chorus emission, forms discrete, rising-tone elements high degree...
Meaningfulness is a profound aspect of our lives. So far, concrete reflection what meaning means in HCI still rare. To understand users as humans, and thus, the humanity being user, we adopt Viktor Frankl's understanding meaning-seeking subjects. make concept meaningfulness more graspable, refer to Frankl calls three existentials life: freedom, responsibility, noos. We elaborate four dimensions, namely an outcome, their embeddedness technology, role interaction, (non-)usage. This followed by...
Abstract Background Caregivers of people with dementia (PwD) are diverse—they live in urban and rural locations, have varying educational backgrounds, different access to resources, relationships the care recipient, etc. However, one common feature all caregivers is need education support on their caregiving journey. Technology provides a feasible way reach such large diverse population. SUccessful Caregiver Communication Everyday Situation Support (SUCCESS) an innovative training coaching...
The International Conference on Quality of Multimedia Experience (QoMEX) provides an annual forum for experts from academia and industry to present discuss current future research multimedia quality, quality experience (QoE) user (UX).The 15th edition the Experience, QoMEX 2023, which is held June 20th 22nd organized in Ghent, Belgium.The theme this "Towards sustainable inclusive experiences", with ambition put sustainability thinking inclusivity more firmly scientific agenda into...
<p>Ring current particles affect the terrestrial magnetic field configuration, altering particle trajectories, as well presenting a surface charging hazard for satellites. These can act seed population electron radiation belts and generate plasma waves. Accurately describing ring dynamics is crucial to understand near-Earth environment. Here we report on our first results of expansion Versatile Electron Radiation Belt (VERB) code model proton (proVERB). We perform sensitivity...
The situatedness of researchers and developers influences the whole research process from ideas to methods results. To assess diversity perspectives in QoE field, we conducted a quantitative content analysis QoMEX proceedings authorship examining five years locality authors (20152019) two gender author type (2018-2019). Our results reveal predominance WEIRD, i.e. Western, Educated, Industrialized, Rich, Democratic, under-representation female authorship, along with other alarming trends....
