College students are exposed to smartphone distraction during study-related contexts (e.g., classrooms, self and group studies). This constant distraction may lower their academic performance. In this work, we built a simple context aware proactive blocking prototype to explore the patterns of focusing contexts, and to evaluate user experiences of proactive blocking for distraction management in study related contexts for college students. Our preliminary user study shows the positive effects of proactive blocking. We discuss several design implications for context-aware proactive blocking and semi-automated logging for distraction management.

Alerts and notifications are increasingly being used in emergency situations. However, notifying users when an alert is not contextually useful results in those users opting out of this mode of alerting. There is a need to extensively evaluate such notifications and understand their utility before adopting them in real-world alert systems. In this paper, we describe OpenAlerts, an open-source software that allows creating and evaluating the impact of simulated alerts and notifications. The proposed system is an extension to a testbed that was used by over two-hundred users across two university campuses to evaluate potential improvements to the US-based Wireless Emergency Alerts. The system allows A/B-type user testing of many potential enhancements including embedding maps, fine geo-targeting of alerts, embedding URLS, and speech-to-text.

We present a concept-based world building approach, realized in a system called VR Safari Park, which allows users to rapidly create and manipulate a world simulation. Conventional world building tools focus on the manipulation and arrangement of entities to set up the simulation, which is time consuming as it requires frequent view and entity manipulations. Our approach focuses on a far simpler mechanic, where users add virtual blocks which represent world entities (e.g. animals, terrain, weather, etc.) to a World Tree, which represents the simulation. In so doing, the World Tree provides a quick overview of the simulation, and users can easily set up scenarios in the simulation without having to manually perform fine-grain manipulations on world entities. A preliminary user study found that the proposed interface is effective and usable for novice users without prior immersive VR experience.

In Massive Open Online Courses (MOOCs), learners face a lot of distractions which will cause divided attention (DA). However, it is not easy for learners to realize that they are distracted and to find out which part of the course they have missed. In this paper, we present Reminder, a system for detecting divided attention and reminding learners what they just missed on both PC and mobile devices with a camera capturing their status. To get learners' attention level, we build a regression model to predict attention score from an integrated feature vector. Meanwhile, we design an interactively updating method to make the model adaptive to a specific user. We also propose a visualization method to help learners review missed content easily. user study shows that Reminder detects learners' divided attention and assists them to review missed course contents effectively.

We present Companion, a software tool tailored towards improving and digitally supporting the pen-and-paper tabletop role-playing experience. Pen-and-paper role-playing games (P&P RPG) are a concept known since the early 1970s [20]. Since then, the genre has attracted a massive community of players while branching out into several genres and P&P RPG systems to choose from. Due to the highly interactive and dynamic nature of the game, a participants' individual impact on narrative and interactive aspects of the game is extremely high. The diversity of scenarios within this context lead to a variety of players' needs, as well as factors limiting and enhancing game-play. Companion offers an audio management workspace for creation and playback of soundscapes based on visual layouting. It supports interactive image presentation and map exploration which can incorporate input from any device providing TUIO tracking data [11]. Additionally, a mobile app was developed to be used as a remote control for media activation on the desktop host.

Biofeedback is commonly used to regulate one's state, for example to manage stress. The underlying idea is that by perceiving a feedback about their physiological activity, a user can act upon it. In this paper we describe through two recent projects how biofeedback could be leveraged to share one's state at distance. Such extension of biofeedback could answer to the need of belonging, further widening the applications of the technology in terms of well-being.

Many requirements for quality in use are elicited in the late development phase. However, if requirements are elicited in the late development phase, the development may return to the previous phase or some requirements cannot be realized due to costs and schedules. To reduce these cases, we propose a method to elicit the requirements in the requirements analysis phase. First, software developers analyze the user characteristics (UCs) of the target users and specify important quality characteristics (QCs) for quality in use and UI design items based on the relationships among UC, QC, and UI design items. Because UI design items are considerations to develop UIs, the specified UI design items are elicited as UI requirements. Thus, when important QCs are specified, UI requirements can be easily elicited by tracing the relationships from QCs to UI design items.

The Track on Recommender Systems: Theory, user Interactions and Applications at acm/SIGAPP symposium on Applied Computing (acm SAC) 2019 provides a dedicated forum to researchers in the area of recommender systems (RecSys) and user modeling for discussing open research problems, solid solutions, latest challenges, novel applications and innovative research approaches in RecSys. The development of RecSys promotes various research topics, such as user interaction and interfaces, algorithm design and evaluations, computational efficiency, and recommendation explanations. As one of applied sciences, the field of recommender systems attracts experts and receives contributions from multidisciplinary areas. This track was hosted in acm SAC in the years of 2013, 2014, 2017 and 2018 previously. Thus, it is already the 5th issue of a track on RecSys research associated with acm SAC.
