Towards a Holistic Approach to Designing Theory-based Mobile Health Interventions

Increasing evidence has shown that theory-based health behavior change interventions are more effective than non-theory-based ones. However, only a few segments of relevant studies were theory-based, especially the studies conducted by non-psychology researchers. On the other hand, many mobile health interventions, even those based on the behavioral theories, may still fail in the absence of a user-centered design process. The gap between behavioral theories and user-centered design increases the difficulty of designing and implementing mobile health interventions. To bridge this gap, we propose a holistic approach to designing theory-based mobile health interventions built on the existing theories and frameworks of three categories: (1) behavioral theories (e.g., the Social Cognitive Theory, the Theory of Planned Behavior, and the Health Action Process Approach), (2) the technological models and frameworks (e.g., the Behavior Change Techniques, the Persuasive System Design and Behavior Change Support System, and the Just-in-Time Adaptive Interventions), and (3) the user-centered systematic approaches (e.g., the CeHRes Roadmap, the Wendel's Approach, and the IDEAS Model). This holistic approach provides researchers a lens to see the whole picture for developing mobile health interventions

Conceptualizing and supporting awareness of collaborative argumentation

In this thesis, we introduce “Argue(a)ware”. This is a concept for an instructional group awareness tool which aims at supporting social interactions in co-located computer-supported collaborative argumentation settings. Argue(a)ware is designed to support the social interactions in the content (i.e., task-related) and in the relational (i.e., social and interpersonal) space of co-located collaborative argumentation (Barron, 2003). The support for social interactions in the content space of collaboration is facilitated with the use of collaborative scripts for argumentation (i.e., instructions and scaffolds of argument construction) as well with the use of an argument mapping tool (i.e., visualization of argumentation outcomes in a form of diagrams) (Stegmann, Weinberger, & Fischer, 2007; van Gelder, 2013). The support for social interactions in the relational space of collaboration is facilitated with the use of different awareness mechanisms from the CSCL and the CSCW research fields (i.e., monitoring, mirroring and awareness notification tools). In this thesis, we examined how different awareness mechanisms facilitate the regulation of collaborative processes in the relational space of collaborative argumentation. Moreover, we studied how they affect the perceived team effectiveness (i.e., process outcome) and group performance (i.e., learning outcome) in the content space of collaboration. Thereby, we studied also the effects of the design of the awareness mechanisms on the application of the mechanisms and the user experience with them. In line with the design-based research paradigm, we attempted to simultaneously improve and study the effect of Argue(a)ware on collaborative argumentation (Herrington, McKenney, Reeves & Oliver, 2007). Through a series of design-based research studies we tested and refined the prototypes of the instructional group awareness tool. Moreover, we studied the ecological validity of dominant awareness and instructional theories in the context of co-located computer-supported collaborative argumentation. The underlying premise of the Argue(a)ware tool is that a combination of awareness and instructional support will result in increased awareness of collaboration, which will, in turn, mediate the regulation of collaborative processes. Moreover, we assume that successful regulation of collaboration will result in high perceived team effectiveness and the group performance in turn. In the first phase of development of the Argue(a)ware tool, we built support of the content space of collaborative argumentation with argument scaffold elements in a pedagogical face-to-face macro-script and an argument mapping tool. Furthermore, we extended the use of the script for supporting the relational space of collaboration by embedding awareness prompts for reflecting on collaboration during regular breaks in the script. Following, we designed two variations of the same pedagogical face-to-face macro-script which differ with respect to the type of group awareness prompts they used for supporting the relational space of collaboration i.e. behavioral and social. Upon designing the two script variations, we conducted a longitudinal, multiple-case study with ten groups of Media Informatics master students (n = 28, in groups of three or two, group=case, 4 sessions x70 min, Behavioural Awareness Script group= 5, Social Awareness Script group =5.) where each group was conceptualized as a case. Students collaborated every time for arguing to solve one different ill-structured problem and for transferring their arguments in the argument mapping tool Rationale. Thereby, we intended to investigate the effects of different awareness prompts on (a) collaborative metacognitive processes i.e., regulation, reflection, and evaluation (b) the relation between collaborative metacognitive processes and the quality of collaborative argumentation as well as (c) the impact of the two script variations on perceived team effectiveness and (d) what was experience with the different parts of the script variations in the two groups and how this fits into the design framework by Buder (2011). The quantitative analysis of argument outcomes from the groups yield no significant difference between the groups that worked with the BAS and the SAS variations. No significant difference between the script variations with respect to the results from the team effectiveness questionnaires was found either. Prompts for regulating collaboration processes were found to be the most successfully and consistently applied ones, especially in the most successful cases from both script variations and have influenced the argumentation outcomes. The awareness prompts afforded an explicit feedback display format (e.g. assessment of participation levels of self- and others) through discussion (Buder, 2011). The prompted explicit feedback display format (i.e., ratings of one’s self and of others) was criticized for running only on subjective awareness information on participation, contribution efforts and performance in the role. This resulted in evaluation apprehension phenomena (Cottrell, 1972) and evaluation bias (i.e., users may have not assessed themselves or others frankly) (Ghadirian et al., 2016). The awareness prompts for reflection and evaluation did reveal frictions in the plan making process (i.e., dropping out of the plan for collaboration) in the least successful groups. Problems with group dynamics (i.e., free-loading and presence of dominance) but were not powerful enough to trigger the desired changes in the behaviors of the students. The prompts for evaluating the collaboration in both script variations had no apparent connection to argumentation outcomes. The results indicated that dominant presence phenomena inhibited substantive argumentation in the least successful groups. They also indicated that the role-assignment influenced the group dynamics by helping student’s making clear the labor division in the group. In the second phase of development of the Argue(a)ware tool, the focus is on structuring and regulating social interactions in the relational space of collaborative argumentation by means of scripted roles and role-based awareness scaffolds. We designed support for mirroring participation in the role (i.e., a role-based awareness visualization) and support for monitoring participation, coordination and collaboration efforts in the role (i.e., self-assessment questionnaire). Moreover, we designed additional support for guiding participation in the role i.e., role-based reminders as notifications on smartwatches. In a between-subjects study, ten groups of three university students each (n = 30, Mage =22y, mixed educational backgrounds, 1x90min) worked with two variants of the Argue(a)ware for arguing to solve one ill-structured problem and transferring their arguments in the argument mapping tool Rationale. Next, to that, students should monitor their progress in their role with the role-based awareness visualization and the self-assessment questionnaire with the basic awareness support (role-based awareness visualization with the intermediate self-assessment) and the enhanced awareness support (additional role-based awareness reminders). Half of the groups worked only with the role-based awareness visualization and the self-assessment questionnaire (Basic Awareness Condition-BAC) while the other half groups received additional text-based awareness notifications via smartwatches that were sent to students privately (Enhanced Awareness Condition- EAC). Thereby, we tested the use of different degrees of awareness support in the two conditions with respect to their impact on a) self-perceived awareness of performance in the role and of collaboration and coordination efforts (measured with the same questionnaire at two time points), b) on perceive team effectiveness, c) group performance. We hypothesized that students in EAC will perform better thanks to the additional awareness reminders that increased the directivity and influenced their awareness in the role. The mixed methods analysis revealed that the awareness reminders, when perceived on time, succeeded in guiding collaboration (i.e., resulted in more role-specific behaviors). Students in the EAC condition improved their awareness over time (between the two measurements). These results indicated that enhanced awareness support in the form of additional guidance through awareness reminders can boost the awareness of students’ performance in the role as well as the awareness of their coordination and collaboration efforts over time by directing them back to the mirroring and monitoring tools. Moreover, students in EAC exhibited higher perceived team effectiveness than the students in BAC. However, no significant differences in building of shared mental models or performing in mutual performance monitoring were found between the groups. However, students in BAC and EAC did not differ significantly with respect to the formal correctness or evidence sufficiency of their group argumentation outcomes. Moreover, technical difficulties with the smartphones used as delivery devices for the awareness reminders (i.e., low vibration modus) hindered the timely perception of the reminders and thus their effect on participation. Finally, the questionnaire on the experience with the different parts of Argue(a)ware system indicated the need for exploring further media for supporting the awareness reminders to avoid the overwhelming effects of the multiple displays of the system and enhancing higher perceptiveness of the reminders with low interruption costs for other group members. The rather high satisfaction with the use of the role-based awareness visualization and the positive comments on the motivating aspects of monitoring how the personal success contributes to the group performance indicate that the group mirror succeeded in making group norms visible to group members in a non-obtrusive way. The high interpersonal comparability of performances without moderating the group ‘s interaction directly in the basic awareness condition was proven to be the favored design approach compared to the combination of group mirror and awareness reminders in the enhance awareness condition. In the third phase of development of Argue(a)ware, we focused on designing and testing different notification modes on different ubiquitous mobile devices for facilitating the next prototype of a notification system for role-based awareness reminders. Thereby, the aim of the system was again to guide students’ active participation in collaborative argumentation. More specifically, we focused on raising students’ attention to the reminders and triggering a prompter reaction to the contents of the reminders whilst avoiding a high interruption cost for the primary task (i.e., arguing for solving the problem at hand) in the group. These goals were translated into design challenges for the design of the role-based awareness notification system. The system should afford low interruptions, high reaction and high comprehension of notifications. Notification systems with this particular configuration of IRC values are known as "secondary display" systems (McCrickard et al., 2003). Next, we designed three low-fidelity prototypes for a role-based notification system for delivering awareness reminders: The first ran on a smartwatch and afforded text-based information with vibration and light notification modalities. The second ran on smartphone and afforded text-based information with vibrotactile and light-based notification modalities. Finally, the third prototype run on a smart-ring which afforded graphical- based (i.e. abstract light) information with and light and vibration notification modalities. To test the suitability of these prototypes for acting as “secondary display” systems, we conducted a within-subjects user study where three university students (n= 3, Mage=28, mixed educational background) argued for solving three different problem cases and producing an argument map in each of the three consecutive meetings (max 90min) in the Argue(a)ware instructional system. Students were assigned the roles of writer, corrector and devil`s advocate and were instructed to maintain the same role across the three meetings. In each meeting, students worked with a different role-based awareness notification prototype, where they received a notification indicating their balloon is not growing bigger after five minutes of not exhibiting any role-specific behaviors. The role-based awareness notification prototypes aimed at introducing timely interventions which would prompt students to check on their own progress in the role and the group progress as visualized by the role-based awareness visualization on the large display. Ultimately, this should prompt them to reflect on the awareness information from the visualization and adapt their behaviors to the desired behavior standards over time. Results showed that students perceived the notifications from all media mostly based on vibration cues. Thereby, the vibration cues on the wrist (smartwatch) were considered the least disruptive to the main task compared to the vibration cues on finger (smartwatch) and the vibration cues on the desk (smartphone). Students also declared that vibration cues on wrist prompted the fastest reaction i.e., attending to notification by interacting with the smartwatch. These results indicate that vibration cues on the wrist can be a suitable notification mechanism for increasing the perceived urgency of the message and prompting the reaction on it without causing great distraction to the main task, as studies previous studies showed before (Pielot, Church, & deOliveira, 2013; Hernández-Leo, Balestrini, Nieves & Blat, 2012). Based on very limited qualitative data on light as notification modality and awareness representation type no inferences could be made about its influence on the cost of interruption, reaction and comprehension parameters comprehensiveness. The qualitative and quantitative data on the experience with different media as awareness notification systems indicate that smartwatches may be the most suitable medium for acting as awareness notification medium with a “secondary display” IRC configuration (low-high-high). However, this inference needs to be tested in terms of a follow up study. In the next study, the great limitations of study (limited data due to low power and mal-structured measurement instruments) need to be repaired. Finally, the focus should be on comparing notification modalities of one medium (e.g., smartphone) based on a larger set of participants and with the use of objective measurements for the IRC parameter values (Chewar, McCrickard & Sutcliffe, 2004). Finally, we draw conclusions based on the findings from the three studies with respect to the role of awareness mechanisms for facilitating collaborative processes and outcomes and provide replicable and generalizable design principles. These principles are formed as heuristic statements and are subject to refinement by further research (Bell, Hoadley, & Linn, 2004; Van den Akker, 1999). We conclude with the limitations of the study and ideas for future work with Argue(a)ware

DOLPHIN: the design and initial evaluation of multimodal focus and context

In this paper we describe a new focus and context visualisation technique called multimodal focus and context. This technique uses a hybrid visual and spatialised audio display space to overcome the limited visual displays of mobile devices. We demonstrate this technique by applying it to maps of theme parks. We present the results of an experiment comparing multimodal focus and context to a purely visual display technique. The results showed that neither system was significantly better than the other. We believe that this is due to issues involving the perception of multiple structured audio sources

Evaluating the effectiveness of physical shape-change for in-pocket mobile device notifications

Audio and vibrotactile output are the standard mechanisms mobile devices use to attract their owner's attention. Yet in busy and noisy environments, or when the user is physically active, these channels sometimes fail. Recent work has explored the use of physical shape-change as an additional method for conveying notifications when the device is in-hand or viewable. However, we do not yet understand the effectiveness of physical shape-change as a method for communicating in-pocket notifications. This paper presents three robustly implemented, mobile-device sized shape-changing devices, and two user studies to evaluate their effectiveness at conveying notifications. The studies reveal that (1) different types and configurations of shape-change convey different levels of urgency and; (2) fast pulsing shape-changing notifications are missed less often and recognised more quickly than the standard slower vibration pulse rates of a mobile device

Smart Sensing Technologies for Personalised Coaching

People living in both developed and developing countries face serious health challenges related to sedentary lifestyles. It is therefore essential to find new ways to improve health so that people can live longer and can age well. With an ever-growing number of smart sensing systems developed and deployed across the globe, experts are primed to help coach people toward healthier behaviors. The increasing accountability associated with app- and device-based behavior tracking not only provides timely and personalized information and support but also gives us an incentive to set goals and to do more. This book presents some of the recent efforts made towards automatic and autonomous identification and coaching of troublesome behaviors to procure lasting, beneficial behavioral changes

Embedding mobile learning into everyday life settings

The increasing ubiquity of smartphones has changed the way we interact with information and acquire new knowledge. The prevalence of personal mobile devices in our everyday lives creates new opportunities for learning that exceed the narrow boundaries of a school’s classroom and provide the foundations for lifelong learning. Learning can now happen whenever and wherever we are; whether on the sofa at home, on the bus during our commute, or on a break at work. However, the flexibility offered by mobile learning also creates its challenges. Being able to learn anytime and anywhere does not necessarily result in learning uptake. Without the school environment’s controlled schedule and teacher guidance, the learners must actively initiate learning activities, keep up repetition schedules, and cope with learning in interruption-prone everyday environments. Both interruptions and infrequent repetition can harm the learning process and long-term memory retention. We argue that current mobile learning applications insufficiently support users in coping with these challenges. In this thesis, we explore how we can utilize the ubiquity of mobile devices to ensure frequent engagement with the content, focusing primarily on language learning and supporting users in dealing with learning breaks and interruptions. Following a user-centered design approach, we first analyzed mobile learning behavior in everyday settings. Based on our findings, we proposed concepts and designs, developed research prototypes, and evaluated them in laboratory and field evaluations with a specific focus on user experience. To better understand users’ learning behavior with mobile devices, we first characterized their interaction with mobile learning apps through a detailed survey and a diary study. Both methods confirmed the enormous diversity in usage situations and preferences. We observed that learning often happens unplanned, infrequently, among the company of friends or family, or while simultaneously performing secondary tasks such as watching TV or eating. The studies further uncovered a significant prevalence of interruptions in everyday settings that affected users’ learning behavior, often leading to suspension and termination of the learning activities. We derived design implications to support learning in diverse situations, particularly aimed at mitigating the adverse effects of multitasking and interruptions. The proposed strategies should help designers and developers create mobile learning applications that adapt to the opportunities and challenges of learning in everyday mobile settings. We explored four main challenges, emphasizing that (1) we need to consider that Learning in Everyday Settings is Diverse and Interruption-prone, (2) learning performance is affected by Irregular and Infrequent Practice Behavior, (3) we need to move From Static to Personalized Learning, and (4) that Interruptions and Long Learning Breaks can Negatively Affect Performance. To tackle these challenges, we propose to embed learning into everyday smartphone interactions, which could foster frequent engagement with – and implicitly personalize – learning content (according to users’ interests and skills). Further, we investigate how memory cues could be applied to support task resumption after interruptions in mobile learning. To confirm that our idea of embedding learning into everyday interactions can increase exposure, we developed an application integrating learning tasks into the smartphone authentication process. Since unlocking the smartphone is a frequently performed action without any other purpose, our subjects appreciated the idea of utilizing this process to perform quick and simple learning interactions. Evidence from a comparative user study showed that embedding learning tasks into the unlocking mechanism led to significantly more interactions with the learning content without impairing the learning quality. We further explored a method for embedding language comprehension assessment into users’ digital reading and listening activities. By applying physiological measurements as implicit input, we reliably detected unknown words during laboratory evaluations. Identifying such knowledge gaps could be used for the provision of in-situ support and to inform the generation of personalized language learning content tailored to users’ interests and proficiency levels. To investigate memory cueing as a concept to support task resumption after interruptions, we complemented a theoretical literature analysis of existing applications with two research probes implementing and evaluating promising design concepts. We showed that displaying memory cues when the user resumes the learning activity after an interruption improves their subjective user experience. A subsequent study presented an outlook on the generalizability of memory cues beyond the narrow use case of language learning. We observed that the helpfulness of memory cues for reflecting on prior learning is highly dependent on the design of the cues, particularly the granularity of the presented information. We consider interactive cues for specific memory reactivation (e.g., through multiple-choice questions) a promising scaffolding concept for connecting individual micro-learning sessions when learning in everyday settings. The tools and applications described in this thesis are a starting point for designing applications that support learning in everyday settings. We broaden the understanding of learning behavior and highlight the impact of interruptions in our busy everyday lives. While this thesis focuses mainly on language learning, the concepts and methods have the potential to be generalized to other domains, such as STEM learning. We reflect on the limitations of the presented concepts and outline future research perspectives that utilize the ubiquity of mobile devices to design mobile learning interactions for everyday settings.Die Allgegenwärtigkeit von Smartphones verändert die Art und Weise wie wir mit Informationen umgehen und Wissen erwerben. Die weite Verbreitung von mobilen Endgeräten in unserem täglichen Leben führt zu neuen Möglichkeiten des Lernens, welche über die engen Grenzen eines Klassenraumes hinausreichen und das Fundament für lebenslanges Lernen schaffen. Lernen kann nun zu jeder Zeit und an jedem Ort stattfinden: auf dem Sofa Zuhause, im Bus während des Pendelns oder in der Pause auf der Arbeit. Die Flexibilität des mobilen Lernens geht jedoch zeitgleich mit Herausforderungen einher. Ohne den kontrollierten Ablaufplan und die Unterstützung der Lehrpersonen im schulischen Umfeld sind die Lernenden selbst dafür verantwortlich, aktiv Lernsitzungen zu initiieren, Wiederholungszyklen einzuhalten und Lektionen in unterbrechungsanfälligen Alltagssituationen zu meistern. Sowohl Unterbrechungen als auch unregelmäßige Wiederholung von Inhalten können den Lernprozess behindern und der Langzeitspeicherung der Informationen schaden. Wir behaupten, dass aktuelle mobile Lernanwendungen die Nutzer*innen nur unzureichend in diesen Herausforderungen unterstützen. In dieser Arbeit erforschen wir, wie wir uns die Allgegenwärtigkeit mobiler Endgeräte zunutze machen können, um zu erreichen, dass Nutzer*innen regelmäßig mit den Lerninhalten interagieren. Wir fokussieren uns darauf, sie im Umgang mit Unterbrechungen und Lernpausen zu unterstützen. In einem nutzerzentrierten Designprozess analysieren wir zunächst das Lernverhalten auf mobilen Endgeräten in alltäglichen Situationen. Basierend auf den Erkenntnissen schlagen wir Konzepte und Designs vor, entwickeln Forschungsprototypen und werten diese in Labor- und Feldstudien mit Fokus auf User Experience (wörtl. “Nutzererfahrung”) aus. Um das Lernverhalten von Nutzer*innen mit mobilen Endgeräten besser zu verstehen, versuchen wir zuerst die Interaktionen mit mobilen Lernanwendungen durch eine detaillierte Umfrage und eine Tagebuchstudie zu charakterisieren. Beide Methoden bestätigen eine enorme Vielfalt von Nutzungssituationen und -präferenzen. Wir beobachten, dass Lernen oft ungeplant, unregelmäßig, im Beisein von Freunden oder Familie, oder während der Ausübung anderer Tätigkeiten, beispielsweise Fernsehen oder Essen, stattfindet. Die Studien decken zudem Unterbrechungen in Alltagssituationen auf, welche das Lernverhalten der Nutzer*innen beeinflussen und oft zum Aussetzen oder Beenden der Lernaktivität führen. Wir leiten Implikationen ab, um Lernen in vielfältigen Situationen zu unterstützen und besonders die negativen Einflüsse von Multitasking und Unterbrechungen abzuschwächen. Die vorgeschlagenen Strategien sollen Designer*innen und Entwickler*innen helfen, mobile Lernanwendungen zu erstellen, welche sich den Möglichkeiten und Herausforderungen von Lernen in Alltagssituationen anpassen. Wir haben vier zentrale Herausforderungen identifiziert: (1) Lernen in Alltagssituationen ist divers und anfällig für Unterbrechungen; (2) Die Lerneffizienz wird durch unregelmäßiges Wiederholungsverhalten beeinflusst; (3) Wir müssen von statischem zu personalisiertem Lernen übergehen; (4) Unterbrechungen und lange Lernpausen können dem Lernen schaden. Um diese Herausforderungen anzugehen, schlagen wir vor, Lernen in alltägliche Smartphoneinteraktionen einzubetten. Dies führt zu einer vermehrten Beschäftigung mit Lerninhalten und könnte zu einer impliziten Personalisierung von diesen anhand der Interessen und Fähigkeiten der Nutzer*innen beitragen. Zudem untersuchen wir, wie Memory Cues (wörtl. “Gedächtnishinweise”) genutzt werden können, um das Fortsetzen von Aufgaben nach Unterbrechungen im mobilen Lernen zu erleichtern. Um zu zeigen, dass unsere Idee des Einbettens von Lernaufgaben in alltägliche Interaktionen wirklich die Beschäftigung mit diesen erhöht, haben wir eine Anwendung entwickelt, welche Lernaufgaben in den Entsperrprozess von Smartphones integriert. Da die Authentifizierung auf dem Mobilgerät eine häufig durchgeführte Aktion ist, welche keinen weiteren Mehrwert bietet, begrüßten unsere Studienteilnehmenden die Idee, den Prozess für die Durchführung kurzer und einfacher Lerninteraktionen zu nutzen. Ergebnisse aus einer vergleichenden Nutzerstudie haben gezeigt, dass die Einbettung von Aufgaben in den Entsperrprozess zu signifikant mehr Interaktionen mit den Lerninhalten führt, ohne dass die Lernqualität beeinträchtigt wird. Wir haben außerdem eine Methode untersucht, welche die Messung von Sprachverständnis in die digitalen Lese- und Höraktivitäten der Nutzer*innen einbettet. Mittels physiologischer Messungen als implizite Eingabe können wir in Laborstudien zuverlässig unbekannte Wörter erkennen. Die Aufdeckung solcher Wissenslücken kann genutzt werden, um in-situ Untestützung bereitzustellen und um personalisierte Lerninhalte zu generieren, welche auf die Interessen und das Wissensniveau der Nutzer*innen zugeschnitten sind. Um Memory Cues als Konzept für die Unterstützung der Aufgabenfortsetzung nach Unterbrechungen zu untersuchen, haben wir eine theoretische Literaturanalyse von bestehenden Anwendungen um zwei Forschungsarbeiten erweitert, welche vielversprechende Designkonzepte umsetzen und evaluieren. Wir haben gezeigt, dass die Präsentation von Memory Cues die subjektive User Experience verbessert, wenn der Nutzer die Lernaktivität nach einer Unterbrechung fortsetzt. Eine Folgestudie stellt einen Ausblick auf die Generalisierbarkeit von Memory Cues dar, welcher über den Tellerrand des Anwendungsfalls Sprachenlernen hinausschaut. Wir haben beobachtet, dass der Nutzen von Memory Cues für das Reflektieren über gelernte Inhalte stark von dem Design der Cues abhängt, insbesondere von der Granularität der präsentierten Informationen. Wir schätzen interaktive Cues zur spezifischen Gedächtnisaktivierung (z.B. durch Mehrfachauswahlfragen) als einen vielversprechenden Unterstützungsansatz ein, welcher individuelle Mikrolerneinheiten im Alltag verknüpfen könnte. Die Werkzeuge und Anwendungen, die in dieser Arbeit beschrieben werden, sind ein Startpunkt für das Design von Anwendungen, welche das Lernen in Alltagssituationen unterstützen. Wir erweitern das Verständnis, welches wir von Lernverhalten im geschäftigen Alltagsleben haben und heben den Einfluss von Unterbrechungen in diesem hervor. Während sich diese Arbeit hauptsächlich auf das Lernen von Sprachen fokussiert, haben die vorgestellten Konzepte und Methoden das Potential auf andere Bereiche übertragen zu werden, beispielsweise das Lernen von MINT Themen. Wir reflektieren über die Grenzen der präsentierten Konzepte und skizzieren Perspektiven für zukünftige Forschungsarbeiten, welche sich die Allgegenwärtigkeit von mobilen Endgeräten zur Gestaltung von Lernanwendungen für den Alltag zunutze machen
