Gesunde Orte: Ein beiläufiges Gesundheitstagebuch mit Ortsbezug
No full textDie Beobachtung und Reflektion des eigenen Gesundheitsverhaltens ist eine wesentliche Grundlage für einen gesunden Lebensstil. Heutige Ansätze zur Selbstbeobachtung mittels Tagebüchern oder Sensoren sind jedoch aufdringlich und aufwändig zu bedienen. Wir stellen daher ein System vor, das durch Nutzung vorhandener Datenquellen ohne zusätzliche Nutzerinteraktion ein beiläufiges Gesundheitstagebuch realisiert. Hierzu verwenden wir Ortsinformationen, die der Nutzer in sozialen Netzwerken zur Verfügung stellt. Eine Evaluation mit 10 Personen zeigt, dass der Ansatz grundsätzlich erfolgversprechend ist
Automotive User Interfaces in the Age of Automation (Dagstuhl Seminar 16262)
No full textThe next big change in the automotive domain will be the move towards automated and semi-automated driving. We can expect an increasing level of autonomous driving in the coming years, resulting in new opportunities for the car as an infotainment platform when standard driving tasks will be automated. This change also comes with a number of challenges to automotive user interfaces. Core challenges for the assistance system and the user interface will be distributing tasks between the assistance system and the driver, the re-engagement of drivers in semi-automated driving back to the driving task, and collaborative driving in which cars collectively work together (e.g., platoons). Overall, in the coming years we will need to design interfaces and applications that make driving safe while enabling communication, work, and play in human-operated vehicles. This Dagstuhl seminar brought together researchers from human computer interaction, cognitive psychology, human factors psychology and also from automotive industry and OEMs to discuss the new interface paradigms for (semi-)automated driving
Ambient Progress Bar - relaxed and efficient work in waiting periods
No full textThe number of emotionally exhausted employees increases due to deadline pressure and multitasking at work. The compliance with deadlines is even more difficult because of the fact that parallel running subtasks interfere with the concentration on a primary task at the computer. These subtasks cause waiting periods that cannot be efficiently used to continue working on the primary task. To solve this problem we developed the Ambient Progress Bar - an ambient display that provides information about the progress of a parallel running subtask in the periphery of the monitor. After a first design phase in which we analysed the context of use, the requirements of our users via a survey and literature research, we tested our first prototype of the Ambient Progress Bar in an empirical usability evaluation. The refined prototype was further used in two experiments in which we were able to show that users working with the Ambient Progress Bar can continue more efficiently and relaxed with their primary task. Thus the Ambient Progress Bar offers a possibility to reduce stress at work and to ease compliance with deadlines and thereby is one solution to decrease the number of emotionally exhausted employees

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Break, Repair, Learn, Break Less: Investigating User Preferences for Assignment of Divergent Phrasing Learning Burden in Human-Agent Interaction to Minimize Conversational Breakdowns
No full textConversational agents (CA) occasionally fail to understand the user's intention or respond inappropriately due to natural language complexity. These conversational breakdowns can happen because of low intent and entity prediction confidence scores. A promising repair strategy in such cases is that the CA proposes to users likely alternatives to proceed. If one of these options matches the user's intention, the breakdown is repaired successfully. We propose that successful repairs should be followed by a learning mechanism to minimize future breakdowns. After a successful repair, the CA, user, or both can learn each other's specific phrasing. This prevents similar phrasings from causing reoccurring breakdowns. We compared user preferences for these learning mechanisms in a scenario-based study with manufacturing workers (). Our result showed that users first prefer to share the learning burden with the CA (61.3%), followed by entirely outsourcing the learning burden to the CA (60.7%) as opposed to themselves.Internet of Thing
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
