SUMMARY:ReLive: Bridging In-Situ and Ex-Situ Visual Analytics for Analyzing Mixed Reality User Studies
DESCRIPTION:The nascent field of mixed reality is seeing an ever-increasing need for user studies and field evaluation\, which are particularly challenging given device heterogeneity\, diversity of use\, and mobile deployment. Immersive analytics tools have recently emerged to support such analysis in situ\, yet the complexity of the data also warrants an ex-situ analysis using more traditional non-immersive visual analytics setups. To bridge the gap between both approaches\, we introduce ReLive: a mixed-immersion visual analytics framework for exploring and analyzing mixed reality user studies. ReLive combines an in-situ virtual reality view with a complementary ex-situ desktop view. While the virtual reality view allows users to relive interactive spatial recordings replicating the original study\, the synchronized desktop view provides a familiar interface for analyzing aggregated data. We validated our concepts in a two-step evaluation consisting of a design walkthrough and an empirical expert user study.

SUMMARY:AvatAR: An Immersive Analysis Environment for Human Motion Data Combining Interactive 3D Avatars and Trajectories
DESCRIPTION:Analysis of human motion data can reveal valuable insights about the utilization of space and interaction of humans with their environment. To support this\, we present AvatAR\, an immersive analysis environment for the in-situ visualization of human motion data\, that combines 3D trajectories\, virtual avatars of people’s movement\, and a detailed representation of their posture. Additionally\, we describe how to embed visualizations directly into the environment\, showing what a person looked at or what surfaces they touched\, and how the avatar’s body parts can be used to access and manipulate those visualizations. AvatAR combines an AR HMD with a tablet to provide both mid-air and touch interaction for system control\, as well as an additional overview to help users navigate the environment. We implemented a prototype and present several scenarios to show that AvatAR can enhance the analysis of human motion data by making data not only explorable\, but experienceable.

SUMMARY:Pet-Robot or Appliance? Care Home Residents with Dementia Respond to a Zoomorphic Floor Washing Robot
DESCRIPTION:Any active entity that shares space with people is interpreted as a social actor. Based on this notion\, we explore how robots that integrate functional utility with a social role and character can integrate meaningfully into daily practice. Informed by interviews and observations\, we designed a zoomorphic floor cleaning robot which playfully interacts with care home residents affected by dementia. A field study shows that playful interaction can facilitate the introduction of utilitarian robots in care homes\, being nonthreatening and easy to make sense of. Residents previously reacted with distress to a Roomba robot\, but were now amused by and played with our cartoonish cat robot or simply tolerated its presence. They showed awareness of the machine-nature of the robot\, even while engaging in pretend-play. A playful approach to the design of functional robots can thus explicitly conceptualize such robots as social actors in their context of use.

SUMMARY:ShapeFindAR: Exploring In-Situ Spatial Search for Physical Artifact Retrieval using Mixed Reality
DESCRIPTION:Personal fabrication is made more accessible through repositories like Thingiverse\, as they replace modeling with retrieval. However\, they require users to translate spatial requirements to keywords\, which paints an incomplete picture of physical artifacts: proportions or morphology are non-trivially encoded through text only. We explore a vision of in-situ spatial search for (future) physical artifacts\, and present ShapeFindAR\, a mixed-reality tool to search for 3D-models using in-situ sketches blended with textual queries. With ShapeFindAR\, users search for geometry\, and not necessarily precise labels\, while coupling the search process to the physical environment (e.g.\, by sketching in-situ\, extracting search terms from objects present\, or tracing them). We developed ShapeFindAR for HoloLens 2\, connected to a database of 3D-printable artifacts. We specify in-situ spatial search\, describe its advantages\, and present walkthroughs using ShapeFindAR\, which highlight novel ways for users to articulate their wishes\, without requiring complex modeling tools or profound domain knowledge.

SUMMARY:Shaping Textile Sliders: An Evaluation of Form Factors and Tick Marks for Textile Sliders
DESCRIPTION:Textile interfaces enable designers to integrate unobtrusive media and smart home controls into furniture such as sofas. While the technical aspects of such controllers have been the subject of numerous research projects\, the physical form factor of these controls has received little attention so far. This work investigates how general design properties\, such as overall slider shape\, raised vs. recessed sliders\, and number and layout of tick marks\, affect users’ preferences and performance. Our first user study identified a preference for certain design combinations\, such as recessed\, closed-shaped sliders. Our second user study included performance measurements on variations of the preferred designs from study 1\, and took a closer look at tick marks. Tick marks supported orientation better than slider shape. Sliders with at least three tick marks were preferred\, and performed well. Non-uniform\, equally distributed tick marks reduced the movements users needed to orient themselves on the slider.

SUMMARY:Automating Contextual Privacy Policies: Design and Evaluation of a Production Tool for Digital Consumer Privacy Awareness
DESCRIPTION:Users avoid engaging with privacy policies because they are lengthy and complex\, making it challenging to retrieve relevant information. In response\, research proposed contextual privacy policies (CPPs) that embed relevant privacy information directly into their affiliated contexts. To date\, CPPs are limited to concept showcases. This work evolves CPPs into a production tool that automatically extracts and displays concise policy information. We first evaluated the technical functionality on the US’s 500 most visited websites with 59 participants. Based on our results\, we further revised the tool to deploy it in the wild with 11 participants over ten days. We found that our tool is effective at embedding CPP information on websites. Moreover\, we found that the tool’s usage led to more reflective privacy behavior\, making CPPs powerful in helping users understand the consequences of their online activities. We contribute design implications around CPP presentation to inform future systems design.

SUMMARY:Designing Visuo-Haptic Illusions with Proxies in Virtual Reality: Exploration of Grasp\, Movement Trajectory and Object Mass
DESCRIPTION:Visuo-haptic illusions are a method to expand proxy-based interactions in VR by introducing unnoticeable discrepancies between the virtual and real world. Yet how different design variables affect the illusions with proxies is still unclear. To unpack a subset of variables\, we conducted two user studies with 48 participants to explore the impact of (1) different grasping types and movement trajectories\, and (2) different grasping types and object masses on the discrepancy which may be introduced. Our Bayes analysis suggests that grasping types and object masses (≤ 500 g) did not noticeably affect the discrepancy\, but for movement trajectory\, results were inconclusive. Further\, we identified a significant difference between (un)restricted movement trajectories. Our data shows considerable differences in participants’ proprioceptive accuracy\, which seem to correlate with their prior VR experience. Finally\, we illustrate the impact of our key findings on the visuo-haptic illusion design process by showcasing a new design workflow.

SUMMARY:(Don't) stand by me: How trait psychopathy and NPC emotion influence player perceptions\, verbal responses\, and movement behaviours in a gaming task
DESCRIPTION:Social interactions are an essential part of many digital games\, and provide benefits to players; however\, problematic social interactions also lead to harm. To inform our understanding of the origins of harmful social behaviours in gaming contexts\, we examine how trait psychopathy influences player perceptions and behaviours within a gaming task. After measuring participants’ (n=385) trait-level boldness\, meanness\, and disinhibition\, we expose them to neutral and angry social interactions with a non-player character (NPC) in a gaming task and assess their perceptions\, verbal responses\, and movement behaviours. Our findings demonstrate that the traits significantly influence interpretation of NPC emotion\, verbal responses to the NPC\, and movement behaviours around the NPC. These insights can inform the design of social games and communities and can help designers and researchers better understand how social functioning translates into gaming contexts

SUMMARY:User Perceptions of Extraversion in Chatbots after Repeated Use
DESCRIPTION:Whilst imbuing robots and voice assistants with personality has been found to positively impact user experience\, little is known about user perceptions of personality in purely text-based chatbots. In a within-subjects study\, we asked N=34 participants to interact with three chatbots with different levels of Extraversion (extraverted\, average\, introverted)\, each over the course of four days. We systematically varied the chatbots’ responses to manipulate Extraversion based on work in the psycholinguistics of human behaviour. Our results show that participants perceived the extraverted and average chatbots as such\, whereas verbal cues transferred from human behaviour were insufficient to create an introverted chatbot.Whilst most participants preferred interacting with the extraverted chatbot\, participants engaged significantly more with the introverted chatbot as indicated by the users’ average number of written words. We discuss implications for researchers and practitioners on how to design chatbot personalities that can adapt to user preferences.

SUMMARY:Proxemics for Human-Agent Interaction in Augmented Reality
DESCRIPTION:Augmented Reality (AR) embeds virtual content in physical spaces\, including virtual agents that are known to exert a social presence on users. Existing design guidelines for AR rarely consider the social implications of an agent’s personal space (PS) and that it can impact user behavior and arousal. We report an experiment (N=54) where participants interacted with agents in an AR art gallery scenario. When participants approached six virtual agents (i.e.\, two males\, two females\, a humanoid robot\, and a pillar) to ask for directions\, we found that participants respected the agents’ PS and modulated interpersonal distances according to the human-like agents’ perceived gender. When participants were instructed to walk through the agents\, we observed heightened skin-conductance levels that indicate physiological arousal. These results are discussed in terms of proxemic theory that result in design recommendations for implementing pervasive AR experiences with virtual agents.

SUMMARY:Actuated Materials and Soft Robotics Strategies for Human Computer Interaction Design
DESCRIPTION:The fields of programmable matter\, actuated materials\, and Soft Robotics are becoming increasingly more relevant for the design of novel applications\, interfaces\, and user experiences in the domain of Human-Computer Interaction (HCI). These research fields often use soft\, flexible materials with elastic actuation mechanisms to build systems that are more adaptable\, compliant\, and suitable for a very broad range of environments. However\, at the intersection between HCI and the aforementioned domains\, there are numerous challenges related to fabrication methods\, development tools\, resource availability\, nomenclature\, design for inclusion\, etc. This workshop aims to explore how to make Soft Robotics more accessible to both researchers and nonresearchers alike. We will (1) investigate and identify the various difficulties people face when developing HCI applications that require the transfer of knowledge from those other domains\, and (2) discuss possible solutions and visions on how to overcome those difficulties.

SUMMARY:Intelligent Music Interfaces: When Interactive Assistance and Augmentation Meet Musical Instruments
DESCRIPTION:The interactive augmentation of musical instruments to foster self-expressiveness and learning has a rich history. Over the past decades\, the incorporation of interactive technologies into musical instruments emerged into a new research field requiring strong collaboration between different disciplines. The workshop “Intelligent Music Interfaces” consequently covers a wide range of musical research subjects and directions\, including (a) current challenges in musical learning\, (b) prototyping for improvements\, (c) new means of musical expression\, and (d) evaluation of the solutions.

SUMMARY:Sustainable Haptic Design: Enabling Hapticians to Collaborate and Share their Work
DESCRIPTION:Haptic devices have been around for decades\, providing critical information\, usability benefits and improved experiences across tasks from surgical operations to playful applications in Mixed Reality. We see more and more software and hardware solutions emerging that provide design tools\, design approaches and platforms\, both in academia and industry. However\, we believe that designers often re-invent the wheel\, and must spend an inordinate amount of time doing their work\, which is not sustainable for long-term research. This workshop aims at gathering people from academia and industry to provide a common ground to discuss various insights on and visions of the field. We aim to bring together the various strands of haptics — devices\, software\, and design — to assess the current state-of-the-art and propose an agenda towards haptics as a united design discipline. We expect the outcome of the workshop to be a comprehensive overview of existing tools and approaches\, along with recommendations on how to move the field forward\, together.

SUMMARY:Automated Vehicles as a Space for Work & Wellbeing
DESCRIPTION:The objective of this CHI course is to provide CHI attendees with an introduction and overview of the rapidly evolving field of automotive user interfaces (AutomotiveUI). The course will focus on UI aspects in the transition towards automated driving. In particular\, we will also discuss the opportunities of cars as a new space for non-driving-related activities\, such as work\, relaxation\, and play. For newcomers and experts of other HCI fields\, we will present the special properties of this field of HCI and provide an overview of new opportunities\, but also general design and evaluation aspects of novel automotive user interfaces.

SUMMARY:HCI Across Borders: Navigating the shifting borders in CHI
DESCRIPTION:HCI research has led to major innovations used by large and diverse audiences in different parts of the world. However\, a recent meta-analysis found that research at CHI is still highly (73%) concentrated in western contexts. HCI Across Borders (HCIxB) has gathered a diverse audience to expand the borders within CHI over the past six years. For CHI 2022\, we expect to regroup to reflect on shifting boundaries from CHI’s past and emerging challenges in research\, teaching\, and practice during the Covid-19 pandemic.
