SUMMARY:ONYX - User Interfaces for Assisting in Interactive Task Learning for Natural Language Interfaces of Data Visualization Tools
DESCRIPTION:While natural language interfaces (NLIs) are increasingly utilized to simplify the interaction with data visualization tools\, improving and adapting the NLIs to the individual needs of users still requires the support of developers. ONYX introduces an interactive task learning (ITL) based approach which enables NLIs to learn from users through natural interactions. Users can personalize the NLI with new commands using direct manipulation\, known commands\, or by combining both. To further support users during the training process\, we derived two design goals for the user interface\, namely providing suggestions based on sub-parts of the command and addressing ambiguities through follow-up questions and instantiated them in ONYX. In order to trigger reflections and gain feedback on possible design trade-offs of ONYX and the instantiated design goals\, we performed a formative user study to understand how to successfully integrate the suggestions and follow-up question into the interaction.

SUMMARY:Standing out among the daily spam: How to catch website owners' attention by means of vulnerability notifications
DESCRIPTION:Running a business without having a website is nearly impossible nowadays. Most business owners use content managements systems to manage their websites. Yet\, those can pose security risks and provide vulnerabilities for manipulations. With vulnerability notifications\, website owners are notified about security risks. To identify common themes with respect to vulnerability notifications and provide deeper insight into the motivations of website owners to react to those notifications\, we conducted 25 semi-structured interviews. In compliance with previous research\, we could confirm that distrust in unexpected notifications is high and\, in contrast to previous research\, we suggest that verification possibilities are the most important factors to establish trust in notifications. We also endorse the findings that raising awareness for the severity and the complexity of the problems is crucial to increase remediation rates.

SUMMARY:The Scent of Collaboration: Exploring the Effect of Smell on Social Interactions
DESCRIPTION:Social interactions are multisensory experiences. However\, it is not well understood how technology-mediated smell can support social interactions\, especially in collaborative tasks. To explore its effect on collaboration\, we asked eleven pairs of users to work together on a writing task while wearing an interactive jewellery designed to emit scent in a controlled fashion. In a within-subjects experiment\, participants were asked to collaboratively write a story about a standardized visual stimulus while exposed to with scent and without scent conditions. We analyzed video recordings and written stories using a combination of methods from HCI\, psychology\, sociology\, and human communication research. We observed differences in both participants’ communication and creation of insightful stories in the with scent condition. Furthermore\, scent helped participants recover from communication breakdown even though they were unaware of it. We discuss the possible implications of our findings and the potential of technology-mediated scent for collaborative activities.

SUMMARY:Virtual Reality for Mind and Body: Does the Sense of Embodiment Towards a Virtual Body Affect Physical Body Awareness?
DESCRIPTION:Mind-body therapies aim to improve health by combining physical and mental exercises. Recent developments tend to incorporate virtual reality (VR) into their design and execution\, but there is a lack of research concerning the inclusion of virtual bodies and their effect on body awareness in these designs.  In this study\, 24 participants performed in-VR body awareness movement tasks in front of a virtual mirror while embodying a photorealistic\, personalized avatar. Subsequently\, they performed a heartbeat counting task and rated their perceived body awareness and sense of embodiment towards the avatar.\nWe found a significant relationship between sense of embodiment and self-reported body awareness but not between sense of embodiment and heartbeat counting.\nFuture work can build on these findings and further explore the relationship between avatar embodiment and body awareness.

SUMMARY:Evaluating Soft Organ-Shaped Tangibles for Medical Virtual Reality
DESCRIPTION:Connecting digital information with the physical is one of the essential ideas of tangible user interfaces. The design of the physical representation is important especially for specialised domains like surgery planning\, because surgeons rely heavily on their tactile senses. Therefore\, this research work investigates the effect of a soft and a hard 3D model as an interaction device for virtual reality surgical planning. A user study with 13 surgeons reveals a clear preference for the softer\, more realistic material and a significantly higher haptic user experience for the soft model compared to the hard one. These results advocate for stressing material aspects along with the interaction design in domains with an inherently high focus on tactile aspects.

SUMMARY:PriCheck - An Online Assistant for Smart Device Purchases
DESCRIPTION:In this paper\, we present PriCheck\, a browser extension that provides privacy-relevant information about smart devices (e.g.\, in an online shop). This information is oftentimes hidden\, difficult to access\, and\, thus\, often neglected when buying a new device.With PriCheck\, we enable users to make informed purchase decisions.\nWe conducted an exploratory study using the browser extension in a simplified (mock) online shop for smart devices. Participants chose devices with and without using the extension.\nWe found that participants (N = 11) appreciated the usability and available information of PriCheck\, helping them with informed decisions for privacy-preserving products. We hope our work will stimulate further discussion on how to make privacy information for novel products available\, understandable\, and easy to access for users.

SUMMARY:cARdLearner: Using Expressive Virtual Agents when Learning Vocabulary in Augmented Reality
DESCRIPTION:Augmented reality (AR) has a diverse range of applications\, including language teaching. When studying a foreign language\, one of the biggest challenges learners face is memorizing new vocabulary. While augmented holograms are a promising means of supporting this memorization process\, few studies have explored their potential in the language learning context. We demonstrate the possibility of using flashcard along with an expressive holographic agent  on vocabulary learning. Users scan a flashcard and play an animation that is connected with an emotion related to the word they are seeing. Our goal is to propose an alternative to the traditional use of flashcards\, and also introduce another way of using AR in the association process.

SUMMARY:E-ScootAR: Exploring Unimodal Warnings for E-Scooter Riders in Augmented Reality
DESCRIPTION:Micro-mobility is becoming a more popular means of transportation. However\, this increased popularity brings its challenges. In particular\, the accident rates for E-Scooter riders increase\, which endangers the riders and other road users. In this paper\, we explore the idea of augmenting E-Scooters with unimodal warnings to prevent collisions with other road users\, which include Augmented Reality (AR) notifications\, vibrotactile feedback on the handlebar\, and auditory signals in the AR glasses. We conducted an outdoor experiment (N = 13) using an Augmented Reality simulation and compared these types of warnings in terms of reaction time\, accident rate\, and feeling of safety. Our results indicate that AR and auditory warnings lead to shorter reaction times\, have a better perception\, and create a better feeling of safety than vibrotactile warnings. Moreover\, auditory signals have a higher acceptance by the riders compared to the other two types of warnings.

SUMMARY:On Appropriation and Nostalgic Reminiscence of Technology
DESCRIPTION:Technological objects present themselves as necessary\, only to become obsolete faster than ever before. This phenomenon has led to a population that experiences a plethora of technological objects and interfaces as they age\, which become associated with certain stages of life and disappear thereafter. Noting the expanding body of literature within HCI about appropriation\, our work pinpoints an area that needs more attention\, “outdated technologies.” In other words\, we assert that design practices can profit as much from imaginaries of the future as they can from reassessing artefacts from the past in a critical way. In a two-week fieldwork with 37 HCI students\, we gathered an international collection of nostalgic devices from 14 different countries to investigate what memories people still have of older technologies and the ways in which these memories reveal normative and accidental use of technological objects. We found that participants primarily remembered older technologies with positive connotations and shared memories of how they had adapted and appropriated these technologies\, rather than normative uses. We refer to this phenomenon as nostalgic reminiscence. In the future\, we would like to develop this concept further by discussing how nostalgic reminiscence can be operationalized to stimulate speculative design in the present.

SUMMARY:SpiderClip: Towards an Open Source System for Wearable Device Simulation in Virtual Reality
DESCRIPTION:Smartwatches and fitness trackers integrate different sensors from inertial measurement units to heart rate sensors in a very compact and affordable form factor. This makes them interesting and relevant research tools. One potential application domain is virtual reality\, e.g.\, for health related applications such as exergames or simulation approaches. However\, commercial devices complicate and limit the collection of raw and real-time data\, suffer from privacy issues and are not tailored to using them with VR tracking systems. We address these issues with an open source design to facilitate the construction of VR-enabled wearables for conducting scientific experiments. Our work is motivated by research in mixed realities in pervasive computing environments. We introduce our system and present a proof-of-concept study with 17 participants. Our results show that the wearable reliably measures high-quality data comparable to commercially available fitness trackers and that it does not impede movements or interfere with VR tracking.

SUMMARY:How do Users Expect their Smart Memory Vaults to Utilize Their Shared Memories?
DESCRIPTION:Social media (SM) is a popular accessible form of smart memory vaults. Prior work shows that users are still unable to understand how their shared memories are used by smart systems to create Smart Interactions involving Personal Memories (SIPMs). This can lead to negative social repercussions such as cyberbullying. This work investigates the most memorable SIPMs on Facebook for Egyptian users and their impact on platform usage. We conducted an online survey (N=53) requesting critical incident reports about surprising Facebook SIPMs. The most remembered SIPMs were: customizing advertisements\, cuing offline interactions\, sharing data with third parties and personalizing the newsfeed. Our results suggest that SIPMs\, particularly customized advertisements act as ambient memory augmentation solutions to the users’ shared memories. Additionally\, negative platform perception does not necessarily translate into reduction of platform usage. Our work inspires the discussion about users expectations towards ambient usage of their data on smart memory vaults.

SUMMARY:Accessibility-Related Publication Distribution in HCI Based on a Meta-Analysis
DESCRIPTION:Accessibility research aims to aid humans that experience minor or major disabilities and conditions. However\, researchers might have limited exposure to certain disabilities\, therefore\, focus on those prevalent in their own lives.\nThis work presents a script-based meta-analysis on addressed populations in accessibility research published on top Human-Computer Interaction (HCI) venues (3617 full papers).\nWe categorize the publications regarding the involved people and their disabilities.\nWe found that work on vision disability makes up for almost one third (28.85%) of the work published in general HCI. In light of these findings\, we present possible conference- and funding-related explanatory approaches and argue that disability research could more reflect the prevalence of disabilities in the world.

SUMMARY:PriCheck - An Online Assistant for Smart Device Purchases
DESCRIPTION:In this paper\, we present PriCheck\, a browser extension that provides privacy-relevant information about smart devices (e.g.\, in an online shop). This information is oftentimes hidden\, difficult to access\, and\, thus\, often neglected when buying a new device.With PriCheck\, we enable users to make informed purchase decisions.\nWe conducted an exploratory study using the browser extension in a simplified (mock) online shop for smart devices. Participants chose devices with and without using the extension.\nWe found that participants (N = 11) appreciated the usability and available information of PriCheck\, helping them with informed decisions for privacy-preserving products. We hope our work will stimulate further discussion on how to make privacy information for novel products available\, understandable\, and easy to access for users.

SUMMARY:cARdLearner: Using Expressive Virtual Agents when Learning Vocabulary in Augmented Reality
DESCRIPTION:Augmented reality (AR) has a diverse range of applications\, including language teaching. When studying a foreign language\, one of the biggest challenges learners face is memorizing new vocabulary. While augmented holograms are a promising means of supporting this memorization process\, few studies have explored their potential in the language learning context. We demonstrate the possibility of using flashcard along with an expressive holographic agent  on vocabulary learning. Users scan a flashcard and play an animation that is connected with an emotion related to the word they are seeing. Our goal is to propose an alternative to the traditional use of flashcards\, and also introduce another way of using AR in the association process.

SUMMARY:E-ScootAR: Exploring Unimodal Warnings for E-Scooter Riders in Augmented Reality
DESCRIPTION:Micro-mobility is becoming a more popular means of transportation. However\, this increased popularity brings its challenges. In particular\, the accident rates for E-Scooter riders increase\, which endangers the riders and other road users. In this paper\, we explore the idea of augmenting E-Scooters with unimodal warnings to prevent collisions with other road users\, which include Augmented Reality (AR) notifications\, vibrotactile feedback on the handlebar\, and auditory signals in the AR glasses. We conducted an outdoor experiment (N = 13) using an Augmented Reality simulation and compared these types of warnings in terms of reaction time\, accident rate\, and feeling of safety. Our results indicate that AR and auditory warnings lead to shorter reaction times\, have a better perception\, and create a better feeling of safety than vibrotactile warnings. Moreover\, auditory signals have a higher acceptance by the riders compared to the other two types of warnings.

SUMMARY:SpiderClip: Towards an Open Source System for Wearable Device Simulation in Virtual Reality
DESCRIPTION:Smartwatches and fitness trackers integrate different sensors from inertial measurement units to heart rate sensors in a very compact and affordable form factor. This makes them interesting and relevant research tools. One potential application domain is virtual reality\, e.g.\, for health related applications such as exergames or simulation approaches. However\, commercial devices complicate and limit the collection of raw and real-time data\, suffer from privacy issues and are not tailored to using them with VR tracking systems. We address these issues with an open source design to facilitate the construction of VR-enabled wearables for conducting scientific experiments. Our work is motivated by research in mixed realities in pervasive computing environments. We introduce our system and present a proof-of-concept study with 17 participants. Our results show that the wearable reliably measures high-quality data comparable to commercially available fitness trackers and that it does not impede movements or interfere with VR tracking.

SUMMARY:On Appropriation and Nostalgic Reminiscence of Technology
DESCRIPTION:Technological objects present themselves as necessary\, only to become obsolete faster than ever before. This phenomenon has led to a population that experiences a plethora of technological objects and interfaces as they age\, which become associated with certain stages of life and disappear thereafter. Noting the expanding body of literature within HCI about appropriation\, our work pinpoints an area that needs more attention\, “outdated technologies.” In other words\, we assert that design practices can profit as much from imaginaries of the future as they can from reassessing artefacts from the past in a critical way. In a two-week fieldwork with 37 HCI students\, we gathered an international collection of nostalgic devices from 14 different countries to investigate what memories people still have of older technologies and the ways in which these memories reveal normative and accidental use of technological objects. We found that participants primarily remembered older technologies with positive connotations and shared memories of how they had adapted and appropriated these technologies\, rather than normative uses. We refer to this phenomenon as nostalgic reminiscence. In the future\, we would like to develop this concept further by discussing how nostalgic reminiscence can be operationalized to stimulate speculative design in the present.

SUMMARY:How do Users Expect their Smart Memory Vaults to Utilize Their Shared Memories?
DESCRIPTION:Social media (SM) is a popular accessible form of smart memory vaults. Prior work shows that users are still unable to understand how their shared memories are used by smart systems to create Smart Interactions involving Personal Memories (SIPMs). This can lead to negative social repercussions such as cyberbullying. This work investigates the most memorable SIPMs on Facebook for Egyptian users and their impact on platform usage. We conducted an online survey (N=53) requesting critical incident reports about surprising Facebook SIPMs. The most remembered SIPMs were: customizing advertisements\, cuing offline interactions\, sharing data with third parties and personalizing the newsfeed. Our results suggest that SIPMs\, particularly customized advertisements act as ambient memory augmentation solutions to the users’ shared memories. Additionally\, negative platform perception does not necessarily translate into reduction of platform usage. Our work inspires the discussion about users expectations towards ambient usage of their data on smart memory vaults.

SUMMARY:Accessibility-Related Publication Distribution in HCI Based on a Meta-Analysis
DESCRIPTION:Accessibility research aims to aid humans that experience minor or major disabilities and conditions. However\, researchers might have limited exposure to certain disabilities\, therefore\, focus on those prevalent in their own lives.\nThis work presents a script-based meta-analysis on addressed populations in accessibility research published on top Human-Computer Interaction (HCI) venues (3617 full papers).\nWe categorize the publications regarding the involved people and their disabilities.\nWe found that work on vision disability makes up for almost one third (28.85%) of the work published in general HCI. In light of these findings\, we present possible conference- and funding-related explanatory approaches and argue that disability research could more reflect the prevalence of disabilities in the world.
