“…The laboratory provided a real and enhanced learning experience for students with poor upper body mobility and was equipped with an intelligent laboratory assistant. Kim et al designed a virtual laboratory system for electronic and digital circuit experiments [16]. Through this system, virtual experimental data similar to real experimental data can be obtained, thereby improving the efficiency of learners and educators.…”

The application of virtual reality technology in science experiment education is a research with practical significance and value in human-computer interaction. However, in some existing education tools based on virtual reality, due to the single interaction mode, the complexity of user intention and the non-physical interaction characteristics brought by virtualization, their experimental teaching ability is limited, resulting in the lack of practical value and popularity. In order to solve these problems, a multimodal interaction model is constructed by fusing gesture, speech and pressure information. Specifically, our tasks include: 1) collecting user input information and time series information to construct basic data input tuples. 2) The basic interaction information is used to identify the user's basic intention, and the correlation degree between the user's intentions is considered to determine the correctness of the current identification intention. 3) It allows users to alternate between multi-channel and single channel interaction. Based on this model, we build a multi-modal intelligent interactive virtual experiment platform (MIIVEP), and design and implement a kind of dropper with strong perception ability, which has been verified, tested, evaluated and applied in the intelligent virtual experiment system. In addition, in order to evaluate this work more effectively, we developed a fair scoring criterion for the virtual experimental system (Evaluation scale of virtual experiment system, ESVES), and invited middle school teachers and students to participate in the verification of the results of this work. Through the user's actual use effect verification and result research, we prove the effectiveness of the proposed model and the corresponding implementation.

“…To address the aforementioned problems, Yang et al [6] and Kim et al [7] both describe the design of a virtual laboratory for digital circuit experiments. The system in [6] only supports drawing wires through drag and drop on pins of circuit elements on a fixed board, which restricts the students' innovative ideas, and it doesn't allow students to design circuits using HDL.…”

“…What's more, the students are only able to interact with the server that works out simulation results, thus lacking interactive learning between students and instructors. The system in [7] adds flash animation to explain the key concepts of the experiment, and it will give some multiple questions to users after virtual experiments to assess the learning effect. Nonetheless, it cannot support programmable experiments, and it still faces the problem of little interaction between the students and the instructors.…”

This Research-to-Practice Work in Progress paper presents DCLab, a web-based system for conducting digital logic experiments online, to improve both the effectiveness and the efficiency of digital logic experiment teaching. DCLab covers all experimental contents required by traditional digital logic experiment classes. It allows the students to draw circuit diagrams or to write VHDL code to design their own circuits, and it provides complete simulation functions. DCLab records the progress of each student and makes it convenient for a student to review the history of his practice. Furthermore, for the instructors, they are able to post homework assignments on DCLab, and the system will automatically add homework projects to the students' home pages. Statistics about how the students perform on the homework will be displayed to the instructors, which may help them develop more effective courses. We have tested DCLab among students in the digital logic course, and the results have confirmed its validity.

This paper presents a web-based Java applet for understanding the concepts in digital logic circuits and student satisfaction survey was carried out in order to show its educational validity. Through our educational Java applet, the learners will be capable of learning the concepts and principles related to digital logic circuit experiments and how to operate virtual experimental equipments and virtual bread board. The proposed educational Java applet is composed of five important components: Principle Classroom to explain the concepts and principles for digital logic circuit operations, Simulation Classroom to provide a web-based simulator to the learners, Virtual Experiment Classroom to provide interactive Java applet about the syllabus of off-line laboratory class, Assessment Classroom, and Management System. With the aid of the Management System every classroom is organically tied together collaborating to achieve maximum learning efficiency. Finally, we have obtained several affirmative effects such as high learning standard, reducing the total experimental hours and the damage rate for experimental equipments.
