Remote Laboratories are online learning environments where a major component of student’s learning objectives is met though visual feedback. This is usually through a static webcam feedback at non-HD resolution. An effective method of enhancing the learning procedure is by tracking certain objects of learning interests in the video feedback. Detect...
Digital electronics laboratory activities involve setting several circuits using logic gates. The circuits are created according to a specific Boolean algebra model or computing components. Such activities include setting up basic gates such as AND OR, NOT etc. followed by complex circuits e.g. Adder, Flip-Flops, Registers. These activities involve...
Constructing augmented reality systems for remote access laboratory environments may seem daunting to many institutions. Utilizing open source tools may benefit from the large user and developer base, providing advice and support. Platforms such as Unity 3D provide comprehensive resources to developers when deciding how to construct a working frame...
Remote Laboratories are used to teach a variety of experiment in an online mode. One of the fields of RAL is control systems where various embedded controller or similar devices such as FPGA, PLC and MicroController Units (MCU) are the main focus of teaching and learning. For these experiments, the students upload a program to the device. Once the...
Programmable Logic Controllers (PLCs) are widely used for industrial control applications. Developing programming skills with these devices is essential for students of electrical engineering, and also for professionals wanting to learn new skills. Whilst programming is performed using software development tools, it is essential that learners have...
Internet of Things (IoT) applications can be seen as network-controlled systems with a distributed architecture connecting many smart objects through the Internet. A typical IoT application aims to connect a set of nodes, capable of processing data and making decisions regarding the goal of the IoT application, with other nodes containing smart obj...
Augmented reality (AR) has a great potential in creating rich user interfaces where users can view and interact with virtual objects. AR can have both passive objects and active objects. The former do not respond to interaction; the latter can be altered in their orientation, shape and position in relation to other virtual objects, for example. Rem...
Remote Access Laboratories (RALs) have been used to develop experimental knowledge about practical engineering topics for a while. Distributed remote laboratories aim to share experiment among institutions and individuals through a distributed architecture. Experiments from diverse areas are combined as part of a larger system. Multiple control str...

... The system is capable of matching the current circuit with the target circuit in a web-based environment as well as finding the possible faults in the current circuit. The system has been shown to use a prototype board for digital electronics which can be scaled to implement bigger interfaces and more complex functions [5]. ...
... 9 shows an image of a video with low resolution, full bode and away from the camera; which is very common in internet videos; still, the eyes are located with the method of Viola & Jones; but techniques such as contour detect or segmentation yield poor results. Although, the eyes segmentation is more successful than detector of contour Sobel; however, a histogram threshold is required for each frame or image; it is clear that methods must be rejected and opt for others to detect movement; since the problem can be solved with high resolution cameras as in [18] which increases the cost. Another alternative is the use of specialized hardware based on FPGA, but most people do not have such an option [19]. ...
... There are three software applications operating in the wearable virtual reality system for lower limb monitoring presented: an Android application, a PC application, and a web server. Both Android and PC applications are designed and implemented using Unity's multiplatform gaming engine [37], [38]. ...
... These devices used colour coding to indicate the speed of the elevator in the 3D model. An additional Arduino device later provided data from the sensors to the client [Maiti et al. 2019]. ...

... There are several studies regarding augmented reality based distance laboratory systems (Andujar et al., 2011;Frank & Kapila, 2017;Maiti et al., 2018;Onime & Abiona, 2016;Vargas et al., 2013). Vargas et al. (2013) see AR as an innovative path to enriching visualization in distance laboratories for engineering education. ...

... Similarly, to the terminology, various definitions and classifications for online laboratories have been proposed over the past two decades, for example, by Dormido-Bencomo (2004), Maiti et al. (2017). Specifically, Dormido-Bencomo (2004) proposed a simplified classification of laboratory environments based on two criteria: type of access to the laboratory resource (local, remote) and nature of the accessed resource (real, simulated). ...
