Assessing the Remote Engineering Lab VISIR at Al-Quds University in Palestine

Abstract

Abstract-Engineering labs play a vital role in engineering education, make science come alive, and supply students with better understanding of theories. As a result, they contribute to the improvement of their knowledge and skills. Remote labs not enable sharing of teaching resources such as devices, equipment and instrumentations between universities, but also relax time and space constraints; yet they are considered as a complementary asset to the traditional hands-on labs. This paper is concerned with a two-stage assessment of the engineering remote lab VISIR. In the first stage, the assessment investigated if the students accept to use VISIR in their future lab courses at the Faculty of Engineering at Al-Quds University in Palestine. In the second stage, a deeper analysis will be performed to compare VISIR to hands-on and simulators based on the evaluation criteria: performance, students' retention rate and satisfaction survey.

Realistic Virtual Cables in a 2D Environment Representing a 3D Virtual Reality

“…Different values for the constants m and n have been used in numerous experiments. The following values of the constants were chosen as optimal in order to provide realistic visualization of the virtual cables: m=7 and n=3.5 (5) The results of the four scenarios with the chosen constants are presented in Figure 6, Figure 7, Figure 8 and Figure 9. In order to test the degree of freedom of the cables, different locations of the common point d (the middle node) are presented for each scenario.…”

“…A similar approach is used in the eLab3d environment [2], however this is a 2DR3D platform, which makes the results less satisfactory and the VR unrealistic (Figure 1b). A more advanced solution has been used in the VISIR platform, which has been reused as a basis for many virtual labs [3,4,5]. The cables are represented with three nodes, two of which are "plugged" in the sockets.…”

VISIR federation: Initial building steps: PILAR experience — Work in progress

“…Federating the existing nodes, plus the ones that will be installed in the VISIR+ project will allow swiftly routing the clients' requests to whichever node can respond. Notice the evidence available on the use of the current VISIR systems from all parts of the world [3][4][5][6][7][8][9].…”

Introducing Remote Laboratory Equipment to Circuits - Concepts, Possibilities, and First Experiences

“…In order to provide an even better fit for our study at UGA, we adopted that survey, took two items out, added fifteen items, and allocated them to five dimensions (Perceived learning, VISIR acceptance, immersion and usability, perceived teacher guidance, time and technical restrictions). For the additional items we took inspiration from other published studies on VISIR and other remote labs [12], [13]. The survey with 33 items has been send out to the students in an online version after the course's last session.…”
