SUMMARY:EyeMeet: A Joint Attention Support System for Remote Meetings
DESCRIPTION:A major challenge in remote meetings is that awareness cues\, such as gaze\, become degraded despite playing a crucial role in communication and establishing joint attention. Eye tracking allows overcoming these obstacles by enabling augmentation of remote meetings with gaze information. In this project\, we followed a participatory approach by first distributing a scenario-based survey to students (n=79) to uncover their preference of eye-based joint attention support (real-time\, retrospective\, real-time & retrospective\, no) for remote university meetings. Building on these findings\, we developed EyeMeet\, an eye-based joint attention support system that combines state-of-the-art real-time joint attention support with a retrospective attention feedback for remote meetings. In a four-week study\, two student groups worked remotely on course assignments using EyeMeet. Our findings of the study highlight that EyeMeets supports students in staying more focused on the meetings. Complementing real-time joint attention support\, retrospective joint attention feedback is recognized to provide valuable support for reflecting and adapting behavior for upcoming meetings.

SUMMARY:Spirituality at the Breakfast Table: Experiences of Christian Online Worship Services
DESCRIPTION:Since the COVID-19 pandemics\, we have witnessed an increase in online worship services. Nevertheless\, HCI has little insight into how technological mediation influences religious experiences and how technology should be designed for use in religious contexts. Therefore\, we see a unique opportunity to understand better real-world experiences of technology use in religious rituals and\, more specifically\, in online worship services. Inspired by contextual design\, We virtually observed and interviewed eight persons during and after participation in online worship services. We identified a field of tension between faith\, everyday life\, individuality\, and community.\nThe data suggests that current online worship service systems do not account for believers’ needs for community\, faith\, or extraordinariness. We discuss opportunities for future research and design\, and aim to contribute to the understanding of online worship service experiences and the design of technology-mediated religious experiences.

SUMMARY:VRySmart: a Framework for Embedding Smart Devices in Virtual Reality
DESCRIPTION:As immersive virtual experiences find their way into our living room entertainment\, they are becoming part of our daily technological consumption. However\, state-of-the-art virtual reality (VR) remains disconnected from other digital devices in our environment\, such as smartphones or tablets. As context switches between acting in the virtual environment and resolving external notifications negatively influence immersion\, we look towards integrating smart devices into virtual experiences. To this aim\, we present the VRySmart framework. Through either optical marker tracking or simultaneous localization and mapping (SLAM)\, embedded smart devices can be used as VR controllers with different levels of integration while their content is incorporated into the virtual context to support the plausibility of the illusion. To investigate user impressions\, we conducted a study ($N = 10$) where participants used a smartphone in four different virtual scenarios. Participants positively assessed smart device usage in VR. We conclude by framing implications for future work.

SUMMARY:"Where did you first meet the owner?'' -- Exploring Usable Authentication for Smart Home Visitors
DESCRIPTION:Visitors in smart homes might want to use certain device features\, as far as permitted by the device owner (e.g.\, streaming music on a smart speaker). At the same time\, protecting access to features from attackers is crucial\, motivating a need for authentication.However\, it is unclear if and how smart home visitors should authenticate as they usually do not have access to respective interfaces.\nWe explore considerations for the design of authentication for visitors evolving around\, e.g.\, the visitors themselves as well as the environment and concrete mechanisms.\nMoreover\, we suggest a concrete idea: security questions to authenticate visitors in smart homes.\nIn an interview study (N=24)\, we found that owners and visitors appreciated the low effort and would adapt our approach.\nWe conclude with future research directions that we hope will spark further discussions around the design of authentication for smart homes\, considering visitors and owners alike.

SUMMARY:Towards Balancing Real-World Awareness and VR Immersion in Mobile VR
DESCRIPTION:Virtual Reality (VR) can be used to create immersive infotainment experiences for car passengers. However\, not much is known about how to best incorporate the essentials of their surroundings for balancing real-world awareness and immersion. To address this gap\, we explored 2D and 3D visual cues of the rear-seat space to notify passengers about different real-world tasks (lower armrest\, take cup\, close window\, and hold handle) during a first-person game in VR. Results from our pilot study (n=19) show that users perceive a lower workload in the task hold handle than all other tasks. They also feel more immersed in VR after completing this task\, compared to take cup and close window. Based on our findings\, we propose real-world task types\, synchronous visual cues\, and various input and transition approaches as promising future research directions.

SUMMARY:"I Want It That Way": Exploring Users' Customization and Personalization Preferences for Home Assistants
DESCRIPTION:Home assistants are becoming a widespread product\, but they mostly come as a compact device and offer very few customization and personalization features\, which often leads to dissatisfaction. With the technological advancements\, these systems are becoming more adaptable to the users’ needs and can better imitate a human personality. To achieve that efficiently\, understanding how different users envision their desired assistant is crucial. To identify people’s customization and personalization preferences and their desired personality for a home assistant\, we designed a set of storyboards depicting a variety of possible features in a domestic setting and conducted a user study (N=15)\, including a series of semi-structured interviews. Our quantitative results suggest that users prefer an agent which is highly agreeable and has higher conscientiousness and emotional stability. Furthermore\, we discuss users’ customization and personalization preferences for a home assistant\, which could be considered when designing the future generation of home assistants.

SUMMARY:If The Map Fits! Exploring Minimaps as Distractors from Non-Euclidean Spaces in Virtual Reality
DESCRIPTION:With non-Euclidean spaces\, Virtual Reality (VR) experiences can overcome the limitations of physical space by using overlapping virtual rooms. However\, the illusion created by these spaces can be discovered\, if the overlap is too large. Thus\, in this work\, we investigate if users can be distracted from the overlap by showing a minimap that suggests that there is none. When done correctly\, more VR space can be mapped into the existing physical space\, allowing for more spacious virtual experiences. Through a user study\, we found that participants uncovered the overlap of two virtual rooms when it was at 100% and above. Our results show that an additional minimap renders overlapping virtual rooms more believable and can serve as an additional tool to overcome physical limitations for natural locomotion in VR.

SUMMARY:Mask removal isn't always convenient in public! -- The Impact of the Covid-19 Pandemic on Device Usage and User Authentication
DESCRIPTION:The ongoing Covid-19 pandemic has impacted our everyday lives and demands everyone to take countermeasures such as wearing masks or disinfecting their hands. However\, while previous work suggests that these countermeasures may profoundly impact biometric authentication\, an investigation of the actual impact is still missing.\nHence\, in this work\, we present our findings from an online survey (n=334) on experienced changes in device usage and failures of authentication.\nOur results show significant changes in personal and shared device usage\, as well as a significant increase in experienced failures when comparing the present situation to before the Covid-19 pandemic.\nFrom our qualitative analysis of participants’ responses\, we derive potential reasons for these changes in device usage and increases in authentication failures.\nOur findings suggest that making authentication contactless is only one of the aspects relevant to encounter the novel challenges caused by the pandemic.
