- Safety in human-robot interaction can be divided into physical safety and perceived safety, where the later is still under-addressed in the literature. Investigating perceived safety in human-robot interaction requires a multidisciplinary perspective. Indeed, perceived safety is often considered as being associated with several common factors studied in other disciplines, i.e., comfort, predictability, sense of control, and trust. In this paper, we investigated the relationship between these factors and perceived safety in human-robot interaction using subjective and objective measures. We conducted a two-by-five mixed-subjects design experiment. There were two between-subjects conditions: the faulty robot was experienced at the beginning or the end of the interaction. The five within-subjects conditions correspond to (1) baseline, and the manipulations of robot behaviors to stimulate: (2) discomfort, (3) decreased perceived safety, (4) decreased sense of control and (5) distrust. The idea of triggering a deprivation of these factors was motivated by the definition of safety in the literature where safety is often defined by the absence of it. Twenty-seven young adult participants took part in the experiments. Participants were asked to answer questionnaires that measure the manipulated factors after within-subjects conditions. Besides questionnaire data, we collected objective measures such as videos and physiological data. The questionnaire results show a correlation between comfort, sense of control, trust, and perceived safety. Since these factors are the main factors that influence perceived safety, they should be considered in human-robot interaction design decisions. We also discuss the effect of individual human characteristics (such as personality and gender) that they could be predictors of perceived safety. We used the physiological signal data and facial affect from videos for estimating perceived safety where participants’ subjective ratings were utilized as labels. The data from objective measures revealed that the prediction rate was higher from physiological signal data. This paper can play an important role in the goal of better understanding perceived safety in human-robot interaction.

- Existing works on interactive sonification of movements, i.e., the translation of human movement qualities from the physical to the auditory domain, usually adopt a predetermined approach: the way in which movement features modulate the characteristics of sound is fixed. In our work we want to go one step further and demonstrate that the user role can influence the tuning of the mapping between movement cues and sound parameters. Here, we aim to verify if and how the mapping changes when the user is either the performer or the observer of a series of body movements (tracing a square or an infinite shape with the hand in the air). We asked participants to tune movement sonification while they were directly performing the sonified movement vs. while watching another person performing the movement and listening to its sonification. Results show that the tuning of the sonification chosen by participants is influenced by three variables: role of the user (performer vs observer), movement quality (the amount of Smoothness and Directness in the movement), and physical parameters of the movements (velocity and acceleration). Performers focused more on the quality of their movement, while observers focused more on the sonic rendering, making it more expressive and more connected to low-level physical features.

- In the era of ‘metaverse’, virtual environments are gaining popularity among new multimedia contents and are also recognized as a valuable means to deliver emotional content. This is favoured by cost reduction, availability and acceptance by end-users of virtual reality technology. Creating effective virtual environments can be achieved by exploiting several opportunities: creating artificial worlds able to generate different stories, mixing sensory cues, and making the whole interactive. The design space for creating emotional virtual environments is ample, and no clear idea of how to integrate the various components exists. This paper discusses how to combine multiple design elements to elicit five distinct emotions. We developed and tested two scenarios per emotion. We present the methodology, the development of the case studies, and the results of the testing. © 2022 Elsevier Ltd

Tidskriftsartikel (refereegranskat)abstract
- New technology and smart homes have the potential to improve quality of life, safety, and care for older people. However, we do not yet know how older people's perceptions of these technologies may vary, in particular how views based on experience of actual use may differ from those related to anticipated use. We also do not know how older people living independently might view technology that may be of future rather than current value to them. This paper explores older people's views of smart home monitoring technology and compares these between people with direct experience and those without. Four focus groups were conducted with six older people recruited from the community with no smart home experience and seven drawn from a large-scale Interdisciplinary Research Collaboration that is developing a sensor platform for health and lifestyle at home. For the seven participants, the sensor platform was installed and operated in their homes for eight to twelve months before the current study.The study found that participants in each group had some similar and some different understandings of smart home technologies. Among participants who had already tried the smart home monitoring technology, acceptance increased over time and with use. They expressed fewer concerns than non smart homes participants regarding privacy, trust, usability, and more concerns about utility. Non smart home participants focused on the extent to which this technology might increase household's vulnerability and they considered the technology somewhat intrusive and noticeable. It appeared that the more positive views of participants who had direct experience of smart homes related to the degree of trust between them and the researchers who installed and maintained the smart home system. Both groups of participants shared views about the technical feasibility, affordability, impact on relationships, and about the engagement and competencies of those who would view the monitoring data. They suggested that the technology would be more acceptable if it was possible to customize functionality and features. These findings have implications for development of smart home technologies so that they are appropriate and acceptable to older people who are living independently.

Tidskriftsartikel (refereegranskat)abstract
- EyeCompass is a novel free-eye drawing system enabling high-fidelity and efficient free-eye drawing through unimodal gaze control, addressing the bottlenecks of gaze-control drawing. EyeCompass helps people to draw using only their eyes, which is of value to people with motor disabilities. Currently, there is no effective gaze-control drawing application due to multiple challenges including involuntary eye movements, conflicts between visuomotor transformation and ocular observation, gaze trajectory control, and inherent eye-tracking errors. EyeCompass addresses this using two initial gaze-control drawing mechanisms: brush damping dynamics and the gaze-oriented method. The user experiments compare the existing gaze-control drawing method and EyeCompass, showing significant improvements in the drawing performance of the mechanisms concerned. The field study conducted with motor-disabled people produced various creative graphics and indicates good usability of the system. Our studies indicate that EyeCompass is a high-fidelity, accurate, feasible free-eye drawing method for creating artistic works via unimodal gaze control.

Tidskriftsartikel (refereegranskat)abstract
- This paper reports on the procedure and results of a preliminary experiment to evaluate participants’ perceptual experiences of a mechanical theatre sound effect and its digital counterpart. The theatre sound effect chosen - an acoustic wind machine - affords a simple rotational gesture; turning its crank handle at varying speeds produces a convincing wind-like sound. A prototype digital model of a working acoustic wind machine was programmed. The mechanical interface of the acoustic wind machine drove both the digital model and its own acoustic sound in performance, therefore preserving the same tactile and kinaesthetic feedback across the two continuous sonic interactions. Participants were presented with two listening tests to examine the perceived similarity of these wind-like sounds and the perceived connection between the speed of the crank handle and the resulting sound. Participants’ performances of both the acoustic and digital systems were then elicited with sound stimuli produced from simple gestural performances of the wind-like sounds. The results of this study show that, while the sound of the prototype digital model requires further calibration to bring the experience of its performance closer to that of its acoustic counterpart, the acoustic wind machine is significantly easier to play, and the mechanism of its interface may play a role in perceptually guiding performance gestures.

Reducing risk to security and privacy in the selection of trigger-action rules: Implicit vs. explicit priming for domestic smart devices

- Smart home device usage is increasing, as is the diversity of users and range of devices. Additionally, it is becoming increasingly common to interconnect devices (e.g., via trigger-action rules) which, while bringing benefits, can bring unforeseen security and privacy risks. Developing strategies to protect users as well as understanding what biographical or attitudinal characteristics contribute to these risks is a critical step for ensuring empowered, but safe, interconnected smart device usage. Using narrative descriptions of domestic smart devices, two experiments explored how the prevailing security/privacy contexts—priming conditions—in which 20 trigger-action rules (developed via a Delphi Study) were presented influenced the adoption of rules favoring either security or privacy. Both experiments contrasted three priming conditions: no prime, security prime, privacy prime. Experiment 1 (n=254) used explicit priming, giving direct instruction to maximize a security or privacy outcome while Experiment 2 (n=325) used implicit priming, with an apparently unrelated security or privacy problem-solving puzzle. Across both experiments, priming promoted safer rule adoption, markedly so when explicit. Explicit priming produced an asymmetry however: privacy priming improved privacy scores with security scores unchanged and security primes improved security scores while worsening privacy scores. Across experiments, two dimensions of user attitudes shaped riskier rule choice: perceived benefits of technology and pre-existing trusting beliefs in online companies. Our novel findings reveal that implicit and explicit priming shape safe use of trigger-action rules in domestic settings and that age, perceived trust and perceived benefits should be considered when designing safety messaging.

- The sense of smell, olfaction, is seldom engaged in digital interactive systems, but, supported by the proper technology, olfaction might open up new interaction domains. Human olfactory experience involves active exploration, directed sniffing and nuanced judgements about odour identity, concentrations, and blends, yet to date most compact olfactory displays do not directly support these experiences. We describe the development and validation of a compact, low-cost olfactory display fitted to the hand controller of the HTC Vive Virtual Reality (VR) system that employs stepless valves to enable control of scent magnitude and blending (Fig. 1). Our olfactory display allows for concealed (i.e., unknown to the user) combinations of odours with virtual objects and contexts, making it well suited to applications involving interactions with odorous objects in virtual space for recreational, educational, scientific, or therapeutic functions. Through a user study and gas sensor analysis, we have been able to demonstrate that our device presents clear and consistent scent output, is intuitive from a user perspective, and supports gameplay interactions. We present results from a smell training game in a virtual wine tasting cellar in which the initial task of identifying wine aroma components is followed by evaluating more complex blends, allowing the player to “level up” as they proceed to higher degrees of connoisseurship. Novice users were able to quickly adapt to the display, and we found that the device affords sniffing and other gestures that add verisimilitude to olfactory experience in virtual environments. Test-retest reliability was high when participants performed the task two times with the same odours. In sum, the results suggest our olfactory display may facilitate use in game settings and other olfactory interactions.

- In recent years, household sustainability has received increasing attention in the field of Human-Computer Interaction. This has largely been driven by the argument that through interaction design, we can create ‘smart homes’ that enable households to be more responsible with precious resources, such as food, water and energy. However, the assumption that home automation technologies lead to improved sustainability may not hold. As a contribution to this discussion, this paper demonstrates how home automation devices promote a lifestyle vision which may undermine intended energy savings. Drawing on a qualitative content analysis of smart home articles, we identify and interrogate the industry vision of ‘pleasance’. We highlight seven qualities that underpin this vision: aesthetic experience, fun and cool, customisation and control, convenience and simplicity, peace of mind, extension and expansion, and effortless energy-saving. We analyse how energy-intensive pleasance is embedded within two commercially available types of devices: smart thermostats and networked lighting. We show how these devices and the pleasance vision that they mobilize may encourage householders to use more energy. The paper concludes with design suggestions on how HCI community can re-envision pleasance through the examples of thermostats and networked lighting to achieve energy reductions and sustainability outcomes.

- Automation is projected to transform many industries and work domains and enable both increased levels of safety and efficiency by reallocating many of the functions traditionally performed by operators. However, research on the relation between automation and work practice is lagging and needs to be further explored in order to ground the debate and design of automated work on a sound empirical basis reflecting work in actual organizational settings. In particular, research is needed that offers rich naturalistic representations of human automation interaction that accounts for the mutual shaping of human and material agency over time. The ethnographic workplace study reported in this paper draws on the sociomaterial practice perspective and on the theory of imbrication to analyze a case in which an automatic speed regulation system was installed onboard five large passenger ferries in order to improve the energy efficiency of the execution of voyages. The results show how the adoption, appropriation and use of automated technologies is inextricable from the local patterns of social interaction and collaboration. The study contributes with a deeper understanding of the relation and entanglement of the social and technological elements in human automation interaction.

- Focusing on interaction needs for scientific data exploration, we evaluated peoples performance using a 2D mouse, 3D SpaceMouse, or 3D-tangible tablet as input devices to interact with visualizations on 2D screens or stereoscopic augmented reality (AR) head-mounted displays. The increasing availability and power of immersive displays drives us to try to understand how to choose input devices, interaction techniques and output displays for the visualization of scientific data, thus to finally help us guide the interaction design for hybrid AR and PC visualization systems. With a docking task and a clipping plane placement/orientation task, we measure our participants performance (completion time and accuracy) with each of the different combinations of input and output. We also report on their perceived workload, their preference, and on other qualitative feedback. Results show that the mouse remains good with any display, especially for tasks that require a high accuracy. Our results highlight the potential to retain the mouse as a primary input device, and to complement it with other 3D interaction devices for specific uses.

- Growing and even excessive use of digital technology has unquestionably fuelled demand for digital devices and online services leading to a wide range of societal and environmental impacts. In sustainability terms, ICT as a whole is estimated to produce up to nearly 4% of global greenhouse gas emissions. As presumed responsible innovators, the HCI community should now consider design strategies that will reduce use and demand for digital technology for the good of both its users and the planet-strategies perhaps even seen as retrogressive in an era where digital technology is constantly implicated in innovation and economic growth. Prior work has noted the potential to design "more moderate" interactions for sustainability, simultaneously addressing negative societal impacts on users' wellbeing, relationships, productivity at work, and privacy. In this paper, we explore how we may design intentionally moderate digital interactions that retain our participants' "more meaningful" experiences. We report on the outcomes of two design workshops to uncover experiences of meaningful device and service use, to inform practical designs for 'moderate and meaningful' interaction. From this, we offer design recommendations that aim to address the multiple negative impacts that digital technology can create, and discuss the possible barriers to these designs.
