Current live eLearning systems enable remote students to view the teaching environment comprising of several information sources such as the teacher and the teaching aids. These information sources are presented as individual video and audio elements. As a result, spatial connections between these elements, such as the teacher using hand gestures to point to an area on the screen, become meaningless...
The recent advancement of web-scale digital advertising saw a paradigm shift from the conventional focus of digital advertisement distribution towards integrating digital processes and methodologies and forming a seamless workflow of advertisement design, production, distribution, and effectiveness monitoring. In this work, we implemented a computational framework for the predictive analysis of the...
This paper proposes a real-time Audio and Video Artifacts Detection Tool (AVADT), solution that wraps implemented artifacts detection methods for most important and common audio and video artifacts. It can also be used for evaluation of different modules and functions of device under testing (e.g. encoder, decoder). AVADT can operate in two modes: offline mode for evaluation of existing, locally stored...
Engineering students conceptualize problems in diverse ways depending how the problems are presented. In this study, we investigate how different representations of problems, such as with images and sketches versus traditional word description of problems, allow students to recall information. Some students experience difficulties visualizing a concept when given a word problem while others do not...
The authoring tools are software applications, for the construction of educational resources that incorporate the possibility of including multimedia elements, that allow to carry and use the resources created in various environments or devices types. Edutools is an authoring tool conceived for the creation of Learning Objects (OA) in HTML format (Hyper Text Markup Language), moreover the tool provides...
ConCIENCIA Estadística is a digital educational material proposed as support for the development of the homonymous workshop, organized in the framework of the Project for Improvement of Training in Exact and Natural Sciences in the Secondary School (Facultad de Ciencias Exactas y Naturales, Universidad Nacional de La Pampa). This material is described in this paper, offering technical details of its...
We present a mobile application for the vowels learning of in children with SD, the methodology of the application design and the description of utilization are explained. The application was used by 4 children for one month (5 sessions per week), the results show that the application is an aid to primary teachers in teaching vowels in children with DS.
Problem based learning, utilizing simulations and virtual reality tools represents one of the approaches integrated into the education of medicine to prepare medical students for both the bedside teaching and their later clinical praxis. On the other side, implementation of innovative didactic materials may be useful also for veterinary medicine students. Thus, veterinary topics can be introduced...
This article aims to improve the math learning process of the students in rural schools. For this purpose, a “Math-fraction” computer animation application was developed to use on the web and mobile technologies. The tool was designed using a visual approach to reinforce student's learning process acquired in classes. The tool was tested and validated by three usability user experts, thirty four students...
A new turn in information revolution contributed to the formation of a new universal identity of the uniform postindustrial society. We refer to this phenomenon as the concept of a “New axial period”. The system of education, like all cultural institutions, turned out to be not ready for such a breakthrough in creating a new reality that entails certain problems. Among the problems are: pedagogical...
Spatial thinking is a prevalent ability required in Science, Technology Engineering, and Math (STEM) domains, which suggests the importance of training spatial abilities. This study investigated a multimedia approach in terms of combing 3D animation and manipulation to train the spatial skills. 128 undergraduates recruited in the experiment revealed that the designed 3-D learning tool is a promising...
In this paper we deal with two image-based object search tasks in the fashion domain, clothing attribute prediction and cross-domain shoe retrieval. Clothing attribute prediction is about describing the appearances of clothes via semantic attributes and cross-domain shoe retrieval aims at retrieving the same shoe items from online stores given a daily life shoe photo. We jointly solve these two problems...
Hashing has been recognized as one of the most promising ways in indexing and retrieving high-dimensional data due to the excellent merits in efficiency and effectiveness. Nevertheless, most existing approaches inevitably suffer from the problem of “semantic gap”, especially when facing the rapid evolution of newly-emerging “unseen” categories on the Web. In this work, we propose an innovative approach,...
Delivering persuasive presentation is a challenging task for the university students. One of the difficult parts is grasping the attention of audiences during the critical situations, such as in the early morning or after the lunch break. At the situations, students are not paying more attention to any speeches or presentations occurred in the classroom because of some lapses of attention span such...
Pedestrian detection, as an important task in video surveillance and forensics applications, has been widely studied. However, its performance is unsatisfactory especially in the low resolution conditions. In realistic scenarios, the size of pedestrians in the images is often small, and detection can be challenging. To solve this problem, this paper proposes a novel resolution-score discriminative...
Despite the increasing consumption and popularity of audio-visual materials and non-textual information, recommendation-based information retrieval research regarding these materials remains limited. To provide robust recommendation services to users, it is critical to understand how users describe their needs when they seek audio- visual materials. We conducted a content analysis of 396 recommendation...
Early childhood English teaching has become a hot topic with the development of informatization and economic globalization, which deserves the urgent attention of schools, teachers and parents. After analyzing the current status of early childhood English teaching, we found several problems including difficulty in inspiring children's learning interest, lack of teaching situation, and low study efficiency...
Visual attention models (VAMs) have proved useful in various multimedia applications such as video encoding, interface design, and user behavior prediction. However, existing VAMs are not generalizable enough to be utilized in all multimedia applications implying that in each application there exist some unique factors which drive the user attention. Application agnostic VAMs rely on video and image...
World wide web (www) is a huge information repository and rapidly growing as source of information. Web pages is known as semi-structured data and it contains variety of information such as text, images, audio, video and other various format. The process of extracting information from the web pages is time consuming and requires correct approach and this paper presents an improvised algorithm in extracting...
Recently the quick development of virtual technology has made technology-aided learning more versified and education revolution more advanced. With visual and audio stimulation, technology-aided teaching can make student pay more attention than traditional way. Currently the way of learning idioms in elementary school is of more traditional way, which, without multiple interactions with students,...
