Reflection is an often addressed design goal in Human-Computer Interaction (HCI) research. An increasing number of artefacts for reflection have been developed recent years. However, evaluating if and how interactive technology helps a user reflect still complex. This makes it difficult to compare (or prototypes) reflection, impeding future efforts. To address this issue, we the \emph{Technology-Supported Inventory} (TSRI), which scale that evaluates effectively system supports reflection....

Over the last decade, smart home technology (SHT) has become an integral part of modern households. As a result, ecosystems blend with daily social life, appropriated and integrated into personalised domestic environments. The lived experience inhabiting ecosystems, however, is not yet understood, resulting in mismatch between ecosystem design inhabitants' needs. Drawing on contextual inquiry methods, we conducted explorative interview study (N=20) SHT users their homes. Our thematic...

While the sport of golf offers unique opportunities for people all ages to be active, it also requires mastering complex movements before can fully enjoyed. Extensive training is required begin achieving any success, which may demotivate prospective players away from sport. To aid beginner golfers and enable them practice without supervision, we designed Subtletee---a system that enhances bodily awareness by providing feedback on position their feet elbows. We first identified key problems...

Accurate dynamic pressure measurements are increasingly important. While traceability is lacking, several National Metrology Institutes (NMIs) and calibration laboratories currently establishing capacities. Shock tubes generating steps with rise times below 1 μs highly suitable as standards for pressures in gas. In this work, we present the results from applying a fast-opening valve (FOV) to shock tube designed measurements. We compare performance of when operated conventional single double...

Smart speakers have become an almost ubiquitous technology as they enable users to access conversational agents easily. Yet, the can only be activated using specific voice commands, i.e. a wake word. This, in turn, requires device constantly listen and process sound, which represents privacy issue for some users. Further, trigger word agent conversation with another human may lead accidental triggers. Here, we propose gestural triggers agents. We conducted gesture elicitation identify five...

Nowadays, various branches of industry are based on continuous processes. Therefore, efficient and accurate data analysis became crucial for maintaining control optimizing the monitored trials. This paper presents a novel solution in-situ complex numerical data. The proposed system employs mixed-reality technology to visualize enable collaborative in remote locations. was implemented using Microsoft HoloLens tested laboratory environment, with its proof-of-concept version applied solve real...

This paper presents a novel approach to complex process of electrical capacitance tomography (ECT) measurement data analysis. ECT is frequently employed for non-invasive monitoring industrial phenomena. Proposed methodology based on the premeditated integration spatial and temporal relations inherent in records into workflow analysis procedure. We propose concept interactive timeline that enables arranging visualization according user's current focus along evaluated proposed method using...

Conducting gesture elicitation studies (GES) in personal spaces such as smart homes is crucial to achieving high ecological validity of elicited gestures. However, supervising considered intrusive and negatively affects the results' quality. The alternative conduct unsupervised GES under similar conditions, but more side-by-side comparisons documenting similarities differences between both approaches are necessary. Consequently, we need data describing preferred approach whether or results...

Due to multimodal approach, the virtual reality experiences become increasingly more immersive and entertaining. New control modalities, such as brain-computer interfaces (BCIs), enable players engage in game with both their bodies minds. In our work, we investigate influence of employing BCI-driven mechanics on player's in-game immersion. We designed implemented an escape room-themed which employed mental states focus relaxation input for selected mechanisms. Through a between-subject user...

Human perception lacks the capabilities to accurately assess distance. The recent Covid-19 pandemic outbreak rendered this ability particularly important. Augmenting our sense of distance can help maintain safe separation from others when required. To explore how systems users physical distance, we designed, implemented and evaluated Gapeau—a head-mounted system for augmenting Our uses proximity sensors thermal sensing detect measure other people. We conducted a validation protocol, an...

Over the recent years, digital jewellery has been creatively explored in research and commercial products. However, symbolic layers of these artefacts which are inherent to traditional not yet understood. Exploring anthropological dimensions wearable ornaments is necessary for become enduring assets personal importance. Drawing on participatory design methods, we conducted an explorative workshop with experts design, art, technology (N=16) discussing socio-technical designing interactive...

This paper investigates the potential of using an electromyographic gesture recognition armband as everyday companion for operating mobile devices in awareness-requiring contexts and suggests fields, which further developments are advisable.The Myo from Thalmic Labs is a fully functional motion controller, based on through EMG muscle sensing.The device has been applied audio control, usability relevance gestural interaction have examined.Participants were asked to operate recording while...

Blending theoretical knowledge with applicable skills is one of the most important challenges in modern higher education, especially STEM areas.
