AR driving assistant for wheelchairs
No full textWheelchairs are an important mobility aid for many people, but our built environment presents them with many challenges. To help those people better navigate our cities, we explore the viability of an informational driving assistant for wheelchairs. Driving assistants have already become commonplace in cars to help drivers control their cars. In this thesis, we present a prototype of a driving assistant for wheelchairs and evaluate it in a user study. To find what information the driving assistant should show to its users, we performed a requirements analysis on what information wheelchair and other mobility aid users might need from such a system and based our prototype on those findings. The results of our user study are inconclusive, because we had too few participants, but the concept itself seems promising.Rollstühle sind für viele Menschen eine wichtige Mobilitätshilfe, aber unsere gebaute Umwelt stellt sie vor viele Herausforderungen. Um diesen Menschen zu helfen, sich in unseren Städten besser zurechtzufinden, untersuchen wir den Nutzen eines informativen Fahrassistenten für Rollstühle. Fahrassistenten sind in Autos bereits gang und gäbe und helfen dem Fahrer, sein Fahrzeug zu kontrollieren. In dieser Arbeit stellen wir einen Prototyp eines Fahrassistenten für Rollstühle vor und evaluieren diesen in einer Nutzerstudie. Um herauszufinden, welche Informationen der Fahrassistent seinen Nutzern anzeigen sollte, haben wir eine Anforderungsanalyse durchgeführt, um herauszufinden, welche Informationen Rollstuhlfahrer und Nutzer anderer Mobilitätshilfen von einem solchen System benötigen könnten, und unseren Prototyp auf diesen Ergebnissen aufgebaut. Die Ergebnisse unserer Nutzerstudie sind nicht aussagekräftig, da wir zu wenige Teilnehmer hatten, aber das Konzept selbst scheint vielversprechend zu sein
Exploring the need for inclusive avatar design
Get PDFThis thesis performs an initial exploration of the topic of avatars with disability. Therefore some related topics are explored, namely VR, avatars and the concepts of immersion, presence and embodiment. Further a survey is conducted to gauge peoples opinion on and thoughts about avatars with disability. Finally a study is conceptualised which aims to find how comfortable disabled people are with using avatars with disability and which reactions they get from others. The survey shows that participants were not opposed to the idea of providing avatars with disability for those who want them however they were more hesitant when asked if they themselves would use such avatars.Diese Abschlussarbeit ist eine erste Exploration des Themas Avatare mit Behinderung. Dafür werden zuerst einige relevante Themengebiete vorgestellt, namentlich VR, Avatare und die Konzepte von Immersion, Präsenz und Verkörperung. Zudem wird eine Umfrage durchgeführt, welche das Ziel hat, die Meinungen und Gedanken der Menschen zu Avataren mit Behinderung herauszufinden. Zum Schluss wird noch eine Studie geplant, die das Ziel hat herauszufinden, wie wohl sich Menschen mit Behinderung fühlen, Avatare mit Behinderung zu verwenden und welche Reaktionen sie von ihren Mitmenschen bekommen. Die Umfrage zeigt, dass die Teilnehmer generell nichts gegen die Einführung von Avataren mit Behinderung haben, allerdings deutlich zurückhaltender sind, wenn es darum geht, solche Avatare selbst zu verwenden
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“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
Get PDFWe 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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
