Abstract
Abstract. Recently, as a consequence of COVID-19 pandemic, the delivery of education at most of the educational institutions depended mainly on e-learning. So, the researchers give more attention for both synchronous and asynchronous e-learning. Although from an economical perspective, asynchronous e-learning seems to be the best e-learning option for institutions, still one of the biggest challenges is how to keep learners motivated for the entire learning process. One of important motivational factors that drives the success of the learning process is the learner attention. Therefore, to retain the learners' attention during the asynchronous e-learning process, we need first to detect their loss of attention. Accordingly, more studies started to focus on detecting learners’ attention. However, those studies can't be widely used for attention detection within asynchronous e-learning environments, as the used approaches tend to be inaccurate, and complex for the design and maintain. In contrast, in this study, we explore the possibility to find a simple way that can be widely used to detect learners' attention within the asynchronous e-learning environments. Therefore, we used webcams which are available in almost every laptop, and computer vision tools to detect learners' attention by tracking their faces. Thereafter, we evaluated the accuracy of our suggested method, the result of this evaluation showed that our method is efficient.
Highlights
E-learning has gained a lot of popularity over the past decades and are being offered to millions of learners around the world
To accomplish this step we used solvePnP function from OpenCV library. This function helps to find face landmarks pose from 2D point correspondences, and it will return the rotation and the translation vectors that transform a 3D point expressed in the face coordinate frame to the camera coordinate frame
The evaluation study procedures that were followed during this part of the research can be summarised as follows: 1. Obtain the learners' for the study
Summary
E-learning has gained a lot of popularity over the past decades and are being offered to millions of learners around the world. There are many applications, platforms, and websites that could be used to deliver the classes online using one or both of the communication methods; asynchronous and synchronous communication. Synchronous e-learning method involves direct real time communication between the teacher and the learners. Asynchronous e-learning method allows the learners to get the knowledge on their pace; at any time and in any place. Examples of synchronous e-learning are video conferences and real-time web chats. Examples of asynchronous e-learning are instructional websites, email, and forum. Examples of asynchronous e-learning are instructional websites, email, and forum. (Hrastinski, 2008)
