Smart speakers become increasingly ubiquitous in our homes. Consequently, we need to study how smart affect the members of a household. Understanding adoption speaker can assure it does not negatively influence social dynamics within household and create opportunities for further assistance. We deployed an Amazon Echo dot nine households with 20 inhabitants who were new users. conducted multiple interviews, inquiring was integrated into from day one. investigated development rules around...
Currently, interactive systems use physiological sensing to enable advanced functionalities. While eye tracking is a promising means understand the user, data inherently suffers from missing due blinks, which may result in reduced system performance. We conducted literature review how researchers deal with this issue. uncovered that often implemented their use-case-specific pipeline overcome issue, ranging ignoring artificial interpolation. With these first insights, we run large-scale...
While advances in mobile text entry enable smartphone users to type almost as fast on hardware keyboards, text-heavy activities are still not widely adopted. One reason is the lack of shortcut mechanisms. In this article, we determine shortcuts for activities, elicit gestures, implement them a fully touch-sensitive smartphone, and conduct an evaluation with potential users. We found that experts perform around 800 keyboard per day, which available smartphones. Interviews revealed major...
Eye tracking is the basis for many intelligent systems to predict user actions. A core challenge with eye-tracking data that it inherently suffers from missing due blinks. Approaches such as intent prediction and state recognition process gaze using neural networks; however, they often have difficulty handling information. In an effort understand how prior work dealt data, we found researchers simply ignore or adopt use-case-specific approaches, artificially filling in data. This...
Recent research has shown that users increasingly seek meaning in technologies and eudaimonic user experience (UX) is part of everyday encounters with technology. Yet, to date, there no validated means assess properties interactive artefacts. We conceptualised, developed a six-item questionnaire for measuring technologies—the Eudaimonic Technology Experience Scale (ETES). Our scale includes two factors, which describe what aspects can be supported by technology: goals self-knowlege....
Physiological sensing enables us to use advanced adaptive functionalities through physiological data (e.g., eye tracking) change conditions. In this work, we investigate the impact of infilling methods on LSTM models' performance in handling missing tracking data, specifically during blinks and gaps recording. We conducted experiments using recommended techniques from previous work an openly available dataset model structure. Our findings indicate that method significantly influences...
Captions are a valuable scaffold for language learners, aiding comprehension and vocabulary acquisition. Past work has proposed enhancements such as keyword highlights increased learning gains. However, little is known about learners' experience with enhanced captions, although this critical adoption in everyday life. We conducted survey focus group to elicit learner preferences requirements implemented processing pipeline captions highlights, time-synchronized captions. A subsequent online...
A steadily increasing number of notifications, auditory, visual or ambient, competes for the user's attention. Frequent unsuitable notifications can lead to a breakdown in efficiency and increase error rates. This paper compares effectiveness, disruptiveness, user experience three different notification modalities: On-Object, ambient On-Environment, On-Smartphone notifications. In study with 24 participants, we evaluate modalities during cooking task where users were frequently exposed Our...
Captions provide language learners with a scaffold for comprehension and vocabulary acquisition. Past work has proposed several enhancements such as keyword highlights increased learning gains. However, little is known about learners' experience enhanced captions, although this critical adoption in everyday life. We conducted survey focus group to elicit learner preferences requirements implemented processing pipeline captions highlights, time-synchronized captions. A subsequent online study...
