Exergaming in mixed reality for the rehabilitation of ataxic patients
No full textBackground: The purpose of a rehabilitation device is to generate tasks among cognitive difficulty stimulating the area of the cerebellum with no-automatics tasks when the situation is new to subject. An emerging technology, which overcomes these shortcomings, is the Mixed Reality. The aim of the study is to evaluate a possible updating of the prototype for rehabilitation of ataxic patients implementing exergame in Mixed Reality. Material and Methods: The version of the prototype based on Microsoft Kinect device and Arduino board with accelerometer/gyroscope sensor, presented in the previous congress, is compared with a reproduction of the same exergame in Mixed Reality environment with the HoloLens (TM) 2. The exergame consists in a pointing and reaching exercise to improve the control of upper limb during daily-life actions. Two subject performed the same exercise on the two different systems to investigate the differences between the systems. Results and Conclusion: The evaluation between the two systems was set up by analysing the differences between the subject's performances with the Kinect-based prototype and the HoloLens application: 3D trajectories and kinematics quantities. Despite of the restricted area of work, the high sample rate of HoloLens permits to follow much-unexpected patient's movements. The application of Mixed Reality for specific rehabilitation allows considering the requests of the therapists and the need of the patient to be always connected with the real world around him instead that in a total virtual space without real reference
Breakthrough in occupational therapy with mixed-reality exergaming for cerebellar ataxia patients
No full textOccupational therapy is a rehabilitation program that aim to recover or maintain the skills needed in daily life activities in order to preserve autonomy. Technologies, such as Virtual Reality and Augmented Reality, have found application in this field where their benefits have been recognised. The aim of this study is to present a mixed reality app for occupational therapy specifically implemented for ataxic patients. The app is implemented in Unity with the integration of the Vuforia asset and it is built for HoloLens2 device. The app can detect a real mug and provide virtual audio-visive feedback to the user during the action of reaching the mug. The audio-visive feedbacks were designed in accordance with an expert. Feedbacks were employed in order to increase concentration on the target and confidence in successfully autonomously complete the action of reaching the target following a virtual straight line. This app could be improved by integrating room-scanning new objects to be detect and feedback according to patient's necessities. Hardware limitations of the HoloLens2 were for this type of application. However, this system has the potential to be of daily support to patients with neuromotor disorders as well as, with the necessary customisation, to the elderly and visually impaired
Kinect-based wearable prototype system for ataxic patients neurorehabilitation: Control group preliminary results
No full textThe aim of this study is to validate the wearable prototype system for ataxic patients' neurorehabilitation based on the Microsoft Kinect device and to archive a preliminary results of a control group of healthy subjects. The system acquires kinematics quantities as 3D position, rotation angles, linear acceleration and angular velocity of the wrist joint during a rehabilitation exercise replayed in 2 different difficulties. The trajectories performed by the 20 subjects were analysed to find the best trajectory and the one completed in the least time. Comparing the acquired performances with the ideal ones, a reference range with which train the patients was obtained. Analysis related to gender and skill abilities were executed
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
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
