Humans always identify persons through their characteristics, salient attributes, and these attributes’ locations on the body. Most person re-identification methods focus on global and local features corresponding to the former two discriminations, cropping person images into horizontal strips to obtain coarse locations of body parts. However, discriminative clues corresponding to location differences cannot be discovered, so persons with similar appearances are often confused because of their alike components. To address the above problem, we introduce pixel-wise relative positions for the invariance of their orientations in viewpoint changes. To cope with the scale change of relative position, we combine relative positions with self-attention modules that perform on multilevel features. Moreover, in the data augmentation stage, mirrored images are given new labels due to the conversion of the relative position along a horizontal orientation and change in visual chirality. Extensive experiments on four challenging benchmarks demonstrate that the proposed approach shows its superiority and effectiveness in discovering discriminating features....
Virtual reality (VR) can be useful in efforts that aim to improve the well-being of older members of society. Within this context, the work presented in this paper aims to provide the elderly with a user-friendly and enjoyable virtual reality application incorporating memory recall and storytelling activities that could promote mental awareness. An important aspect of the proposed VR application is the presence of a virtual audience that listens to the stories presented by elderly users and interacts with them. In an effort to maximize the impact of the VR application, research was conducted to study whether the elderly are willing to use the VR application and whether they believe it can help to improve well-being and reduce the effects of loneliness and social isolation. Self-reported results related to the experience of the users show that elderly users are positive towards the use of such an application in everyday life as a means of improving their overall well-being....
Given the rising psychological challenges encountered by university students, there is an imperative to address the pressing need for enhancing their psychological capital. This study is to design an innovative multimedia system that seeks to offer comprehensive psychological support and promotion mechanisms for university students. This is achieved through the integrated use of various media forms. Multimedia system group counseling was employed to assess and enhance the psychological capital of college students. This study comprises two main components: first, an analysis of the application of multimedia technology in education, and second, an empirical investigation into college students’ psychological capital through a questionnaire survey. The findings reveal that the introduction of group counseling via a multimedia system significantly enhances the psychological capital of college students. This improvement in psychological capital positively impacts the well-being and mental states of students and contributes novel ideas to mental health education for college students. The effectiveness of the group counseling intervention scheme within the multimedia system is evident, suggesting its potential for widespread adoption. The utilization of multimedia systems in educational settings emphasizes the importance of positive psychology for students and contributes to cultivating a positive and healthy psychological state. This study serves as a valuable reference for enhancing the psychological capital of college students, focusing on aspects such as independent thinking, decision-making, and execution....
Background Medical education increasingly relies on digital learning materials. Despite recognition by the Association of American Medical Colleges Institute for Improving Medical Education, medical education design often fails to consider quality multimedia design principles. Further, the AAMC-IIME issued a call to study the role of design principles in medical education. Thus, the current study investigated the cognitive and affective effects of redesigning PowerPoint slides used to support pharmacology content during the preclinical years of medical school training. Methods Researchers implemented a quasi-experimental design, using traditionally-designed (original) slides with a Traditional group (n = 100) and slides redesigned to follow principles from the Cognitive Theory of Multimedia Learning with an Experimental group (n = 40). Participants in the Experimental group completed a post-survey incorporating the Situational Interest Survey for Multimedia to indicate motivational engagement with the media. Students in the Experimental group also responded to additional preference questions. Researchers analyzed survey responses and students’ scores in pharmacology-related coursework across the preclinical Foundations Phase of training to determine the impact on achievement and motivation. Results Findings related to learner achievement showed a modest but significant increase in the Experimental group compared to the Traditional group in the Cardiac, Pulmonary, and Renal (CPR) educational block (105%, normalized to Traditional group, p = 0.013) and cumulative pharmacology grades (101%, normalized to Traditional group, p = 0.043). Additionally, participants in the Experimental group indicated a significantly higher average triggered situational interest in redesigned slides (M = 4.85, SD = 0.25) than the original slides (M = 3.23, SD = 1.40, t=-6.33, p < 0.001). Similarly, the interest rating of the redesigned slides (M = 4.87, SD = 0.24) was significantly greater than that of the original slides (M = 3.89, SD = 0.86, t=-6.824, p < 0.001). Moreover, results further indicated significant differences in the maintained-feeling and maintained-value constructs, and all participants in the Experimental group indicated a preference for the redesigned slides. Conclusions The findings provide strong evidence in support of using the Cognitive Theory of Multimedia Learning design principles to intentionally design media in medical education. In addition to increased achievement scores, students in the Experimental group demonstrated significantly higher levels of situational interest in the redesigned slides, especially triggered interest and maintained-feeling interest. Medical education learning designers should seriously consider redesigning media to achieve similar results....
The purpose of this paper is to study the practice of multimedia technology in the teaching of scientific and technical English. With the rapid development and popularisation of computer technology and the deepening of educational concepts, multimedia-assisted English teaching has become one of the most important foreign language teaching modes at present. This study firstly analyses the impact of multimedia technology on English teaching, secondly faces the advantages and challenges of multimedia technology in the teaching process, and finally explores the use and effect of multimedia technology in scientific and technological English teaching based on the data of the survey and research. The results of the study show that for college English teachers in colleges and universities, they should fully explore the advantages of multimedia technology in the process of using it and use it skillfully in teaching practice, which will have a positive effect on improving the quality of English teaching and deepening the reform of college English teaching....
