abstract = {The effective delivery of e-learning depends on the continuous monitoring and management of student attention. While instructors in traditional classroom settings can easily assess crowd attention 

through gaze cues, these cues are largely unavailable in online learning environments. To address this challenge and highlight the significance of our study, we collected eye movement data from 

twenty students and developed four visualization methods: (a) a heat map, (b) an ellipse map, (c) two moving bars, and (d) a vertical bar, which were overlaid on 13 instructional videos. Our results revealed unexpected preferences among the instructors. Contrary to expectations, they did not prefer the established heat map and vertical bar for live online instruction. Instead, they chose the less 

intrusive ellipse visualization. Nevertheless, the heat map remained the preferred choice for retrospective analysis due to its more detailed information. Importantly, all visualizations were found to be useful and to help restore emotional connections in online learning. In conclusion, our innovative visualizations of crowd attention show considerable potential for a wide range of applications, extending beyond e-learning to all online presentations and retrospective analyses. The significant results of our study underscore the critical role these visualizations will play in enhancing both the effectiveness and emotional connectedness of future e-learning experiences, thereby facilitating the educational landscape.},

abstract = {This work aims to provide tactile feedback when touching elements on everyday surfaces using their resonant frequencies. We used a remote speaker to bring a thin wooden surface into vibration for providing haptic feedback when a small graphical fly glued on the board was touched. Participants assigned the vibration to the fly instead of the board it was glued on. We therefore explored when that assignment illusion works best. The results indicate that additional sound, as well as vibration, lasting as long as the touch, are essential factors for having an assignment of the haptic feedback to the touched graphical object. With this approach, we contribute to ubiquitous and calm computing by showing that resonant frequency can provide vibrotactile feedback for images on thin everyday surfaces using only a minimum of hardware.},

abstract = {Research has explored head-worn displays (HWD) in various professional contexts. However, evaluations have been limited by short-term use, a focus on the person using the HWD, and on performance variables. In a field study, we evaluated a monocular, opaque HWD for multi-patient monitoring, which supervising anesthesiologists wore for 8-10 days each. We investigated the effect of prolonged HWD use on the experience of the supervising anesthesiologists and their co-workers using interviews and repeated observations. A reflexive thematic analysis showed (1) interaction and mindset changes over time, (2) information on the HWD is more than numbers, (3) the HWD affects co-workers' collaboration with supervisors, and (4) distraction depends on the point of view. Using activity theory, we discuss the fact that HWD use develops and changes over time and that even a single-user HWD influences the collaboration with co-workers. We conclude with implications for HWD design, implementation, and evaluation.},

abstract = {Over the last decade, smart home technology (SHT) has become an integral part of modern households. As a result, smart home ecosystems blend with daily social life, appropriated and integrated into personalised domestic environments. The lived experience of inhabiting smart home ecosystems, however, is not yet understood, resulting in a mismatch between ecosystem design and inhabitants’ needs. Drawing on contextual inquiry methods, we conducted an explorative interview study (N=20) with SHT users in their homes. Our thematic analysis reveals how users shape their smart home ecosystems (SHEs), considering social relationships at home, perceived ownership of SHTs, and expected key benefits. Notably, our analysis shows that household members consciously choose ‘their’ level of SHT interconnectedness, reflecting social, spatial and functional affinities between systems. Following our findings, we formulate five implications for designing future SHTs. Our work contributes insights on the dynamics and appropriation of smart home ecosystems by their inhabitants.},

abstract = {In today’s rapidly evolving technological landscape, the convergence of innovation and tradition has given rise to a fundamental question: Can we embrace the convenience of smart devices without sacrificing the aesthetics and emotional resonance of our cherished everyday objects? We help answer this question through our demo, Vasi-Light, a decorative vase enhanced with concealed sensors and conductive ink to allow end-users to control a smart bulb. Vasi-Light seeks to blend the beauty of familiar household items with the intelligence of modern technology. While a smart bulb and vase are used in the demo, the design process and technologies apply to various everyday object/smart appliance pairings and offer exciting opportunities for research into rich interactions with everyday objects and surfaces for future smart homes.},
