    Learner centered design approach for E-learning using 3D virtual tutors
    (IEEE Computer Society help@computer.org, 2013) Mukherjee, S.; Singhal, H.; Jha, P.; Kokane, A.; Rastogi, P.; Mittal, R.; Guddeti, G.
    Most of the existing E-learning system designs have focused on the development of feature-rich, but usable systems with little effort in motivating students to develop interest in the teaching-learning process. This paper discusses the learner centered design approach for web-based tutoring to motivate young learners using 3D virtual tutors in a requirement-based, flexible pedagogical model. Students can choose course(s) and the study-mode. In the guided mode, the student is mentored by a human tutor, whereas a student in un-guided mode is tutored by 3D avatar. The student has access to study materials, educational videos and applets that are provided by the tutors, the student also has access to forums for doubt clearing and online assignments to be submitted for tutors' evaluation. Tutors can track students' progress using online quiz and reports modules. Further, tutors have access to teaching aids like online chat system and whiteboard-based teaching in a virtual classroom environment. © 2013 IEEE.

    Effective E-learning using 3D Virtual Tutors and WebRTC Based Multimedia Chat
    (Institute of Electrical and Electronics Engineers Inc., 2014) Kokane, A.; Singhal, H.; Mukherjee, S.; Guddeti, G.R.M.
    This paper discuss the novel implementation of Learner Centered Design Approach of E-learning System using 3D Virtual Tutors [1] and further enhances this work in facilitating young learners to interact with human tutors using WebRTC Based Multimedia Chat system. The present work adds three main features such as: Firstly, addition of live video lecture session by which students can interact with the tutor just like video call of Skype system. Secondly, the presentation of 3D virtual tutors' narrations of articles in the text form of live transcriptions of avatars' speech. Thirdly, introduction of timed quiz by which a real-life objective examination can be mimicked and thereby evaluating the performance of students. Lastly, we present a comparative evaluation of the original system and its improved version with respect to responses received from a large pool of young learners using the system. © 2014 IEEE.

    Conceptualization and Design of Remotely-Accessible Hardware Interface (RAHI) Laboratory
    (Springer Science and Business Media Deutschland GmbH info@springer-sbm.com, 2021) Potdar, S.M.; Gupta, V.; Umesh, P.; Gangadharan, K.V.
    With the rising popularity of e-learning through means like Massive Open Online Courses (MOOCs), remote-triggered and virtual laboratories, new and innovative technologies for enhancing the learning experience are in demand. E-learning resources for electronics hardware are generally simulation-based, as getting access to high-end hardware is difficult for students due to cost and availability. In this paper, a novel method to create a remotely-accessible, low-cost, modular, and scalable hardware learning platform is proposed and demonstrated through a prototype. Users can interact with the system through a web interface anytime-anywhere and verify results on actual hardware through real-time visual and textual feedback and learn at their pace. The prototype demonstrates a web application hosted on a Linux-PC server interacting with a Raspberry Pi. Student activities are logged in a database for future reference and correction by instructors. The software stack used for the system is free and open-source. The prototype system was launched on a pilot run, gaining positive feedback from students and teachers. Hence, such a system can undergo comprehensive implementation in educational institutions and for the delivery of MOOCs with minimal investment for both laboratory setups and learners. © 2021, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
