AI-based User Emotion Recognition from Interaction Data : Challenges and Guidelines for Training Data Creation
No full textArtificial Intelligence (AI) is a rising topic in the field of emotion recognition, e.g., from facial expressions. However, existing methods often require to be performed in staged set ups and are obtrusive by gathering additional data. Especially, collecting video data includes a high data protection risk. Our approach is to provide an unobtrusive emotion recognition tool based on Keystroke, Mouse and Touchscreen (KMT) data. Recently, we published a data set for emotion recognition from keystroke and mouse interaction data. In this paper, we present the challenges we faced during the creation of the data set. This covers collecting User Interface (UI) data as well as emotional ground truth data. For each of seven mentioned challenges, we provide our solutions as well as guidelines for other researchers to prevent them. The challenges include possible issues with recorded data as well as issues of automated facial coding engines. We provide a possible approach for manual facial coding and describe aspects attention should be paid to. Furthermore, we indicate issues when using different software tools to collect the data. The paper aims to help other researchers by providing insights and a guideline for the creation of the data set. We make these insights available for other researchers who want to create similar data sets or who want to expand ours. By sharing our insights, we aim to improve the reproducibility of AI training data creation and AI-based emotion recognition from user interaction data
Automated Usability Smell Detection in VR Applications with AutoQUEST
No full textThe quality of software products is not only measured by their set of functionality and features, the User Experience (UX) and the quality of the applications’ User Interface (UI) gets more and more important. In order to measure and improve the usability of UIs, it is often required to perform user tests with potential future users. Performing these user tests, taking notes meanwhile and analyzing all the collected data to derive some meaningful results can be a time-consuming task. An automated approach to evaluate the usability of UIs may save time and help to improve the UX. In this tutorial, we present AutoQUEST, a set of tools to automatically record user interaction data and perform automated usability evaluation. The evaluation is done by detecting common interaction structures and assessing them with respect to patterns representing known UX issues. We will demonstrate this usability evaluation technique on an existing study of a Virtual Reality (VR) application of our own
Creating Virtual Prototypes of Technical Devices using Vivifly
No full textWhen developing technical devices, such as home appliances, their user interfaces must be evaluated with respect to usability and user experience. For this, companies create expensive real world prototypes of these devices, ask users to interact with them, and record any issues the users have. Virtual Prototypes (VPs) provided in eXtended Reality (XR) may serve the same purpose with the advantage of being cheaper and more widespread available. Unfortunately, the creation of VPs, especially for multi-platform XR, is nowadays challenging and requires game programming skills. In this tutorial, we present Vivifly and Vivian, two tools for configuring and running simple VPs in different variants of XR. Through this, companies can easily create VPs for their devices under development and test them with users in mobile Augmented Reality (AR), in Virtual Reality (VR), or in Mixed Reality (MR) using a single configuration
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
