Abstract:

The present paper aims at the comparative analysis of some techniques used more and more frequently in the current pandemic context, highlighting the advantages and disadvantages of concepts, the applicability limits and usefulness of these practices in modern education, the final goal being to improve learning outcomes, digital skills and communication in various engineering fields.

Virtual Reality (VR) refers to a system of concepts, methods and techniques that are used in the development and construction of software products that make the new IT and computing systems (computers, specialized and intelligent IT equipment). These items present the way in which the computer and the intelligent, specialized equipment modify the way in which we perceive the reality from the natural environment, by simulating / modeling another reality.

The Augmented Reality (AR) is the next technological step of virtual reality, which complements the surrounding reality without completely replacing it.

Last but not least, Quick Response (QR) codes are becoming increasingly popular in the education process as they provide users with free access to a large volume of information.

Therefore, VR, AR and QR are considered rapid learning tools, for example through operator training simulators (OTS). Additionally, given the widespread application, these technologies involve the students in a whole new way, thus improving the learning process.
