Design of Body Transformation Experience
No full textHumans can feel an illusory body ownership towards bodies that are different from the real one. It has been well studied how the virtual embodiment can be realized and what can be embodied. However, it is not clear how we feel when our body changes from one body to another. We aimed to provide different experiences of body transformation by varying the transition patterns of avatars. We created five types of avatar transitions. In Flicker process, the body appearance changes instantly from one avatar to another, but with a blank screen in the middle. In Cut process, the body appearance changes instantly without blank. In Smooth process, the avatar's body appearance transforms gradually and smoothly according to a smoothstep function. In Linear process, the avatar's body appearance transforms gradually according to a linear function. InWave process, the avatar's body appearance transforms like a wave or back and forth according to a mixture of linear function and sinusoidal function. We expect that participants will be the most aware of body transformation in the Wave transition followed by Linear and Smooth transitions. The Flicker and Cut transitions are natural and less noticed by participants.ICAT-EGVE 2023 - International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments - Posters and DemosPosters and Demo
Visual Search of Interactive Gaze in a Virtual Environment: Detecting Eye Contact is Faster than Gaze Averting
No full textWe often gaze at each other when we communicate with others intimately. A previous study with static stimuli has revealed that perception of others' gaze is asymmetric only when the head is deviated; gazing face target is found faster than averting gaze target. However, the gaze research has been limited to static eye's stimuli, and the perceptual processing of dynamic gaze has not yet been investigated. Therefore, we created dynamic and interactive gaze stimuli of frontal heads in a virtual environment using a head mounted display that can measure eye movements, and conducted visual search experiments. We found that the gaze contacting target presented among gaze averting distractors was detected faster than the gaze averting target among gaze directing distractors. Thus, the detecting eye contact is faster than gaze averting even with frontal faces in dynamic environments, suggesting that dynamic eye contact has a special value for human perception.ICAT-EGVE 2019 - International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments - Posters and DemosPoster
Embodiment from Virtual Hands-and-feet Movements during walking
No full textThis study investigated the influence of global self-motion (walking) on the sense of whole-body ownership induced by virtual hands-and-feet stimuli that moved synchronously with participants. Participants were exposed to normal and scrambled arrangements of hands and feet, while performing reaching tasks with or without walking. Results showed that scrambled hand-and-feet arrangements significantly decreased the sense of part-body ownership, whole-body ownership, invisible body perception, and agency. It did not significantly improve whole-body or part-body ownership. These findings suggest that global self-motion might not be a crucial factor in enhancing body ownership, and further research is needed to explore alternative methods for improving the embodiment.ICAT-EGVE 2024 - International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments - Posters and DemosPoster
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
