Two technologies, virtual reality (VR) and augmented reality (AR), provide users with positive and enriching experiences for immersive training. In addition, these technologies have great potential for training in a variety of fields, such as education, health, entertainment, and industry. This article explains the differences between virtual reality and augmented reality, presents examples of their applications in training, and discusses their advantages and disadvantages.
Virtual reality (VR) is a technology that creates a completely digital environment that mimics reality, allowing the user to explore and interact with devices such as headsets, gloves, or controllers. Virtual reality allows the user to enter a virtual world and feel part of it. For example, virtual reality can be used to train doctors in complex surgeries for safe patients or to teach students abstract concepts in a fun and visual way.
Augmented reality (AR) is a technology that places digital elements on top of the real world that the user sees through a screen or glasses. Augmented reality allows the user to interact with virtual objects or obtain additional information to improve their vision of reality. AR, for example, can be used to teach workers how to use machinery or equipment without having to go to the workplace, or to teach customers how a product would look at home before they buy it.
Users are more engaged and motivated to participate in training thanks to more engaging and personalized experiences such as:
- Stimulate various senses and promote experiential learning to facilitate learning and retention of information.
- Reduce the costs and risks of face-to-face training by avoiding hazardous travel, materials, or situations.
- By providing immediate feedback and the possibility of repeating the practices, it improves the performance and competence of the users.
However, the use of virtual reality and augmented reality in training presents some challenges, such as:
- The need for specific devices and software, which may be expensive or difficult to obtain or maintain.
- Create technical or compatibility issues that may affect the quality or functionality of experiences.
- It can cause negative side effects in some users, such as dizziness, nausea, eyestrain, or Internet addiction.
- Adapt to the needs and preferences of each user, respecting ethical and legal aspects.
Basic Immersive Training Technologies
Virtual Reality (VR):
VR is a technology that completely immerses the user in a virtual environment created by a computer. Users can explore and participate in simulated scenarios that mimic real situations through the use of motion controllers and headsets. VR allows students to practice complex skills in a safe and controlled environment within the training setting. For example, pilots can practice flights without endangering anyone, and doctors can be trained in surgical procedures without risk to patients. Since users can interact with objects and receive instant feedback, VR also encourages active learning.
Augmented Reality (AR):
AR overlays digital information on the physical environment in real time by combining virtual elements with the real world. You can experiment with this technology through special lenses or through mobile devices, such as smartphones or tablets. In the context of education, augmented reality provides the opportunity to bring additional and contextual data into the learning environment.
Architecture students, for example, can view building models in three dimensions on a table, allowing them to better explore and understand structural features. In real time, industrial workers can receive visual instructions while performing complex tasks. AR enhances understanding and the learning experience by providing an additional layer of information.
Mixed Reality (MR):
In MR, elements of virtual reality and augmented reality are combined to create an environment in which virtual objects interact realistically with the real world. Users can manipulate virtual objects and experience interaction with the physical environment through the use of motion sensors and special headphones.
MR in the training setting allows for deeper immersion and more natural interaction with educational content. Chemistry students, for example, can carry out virtual experiments in a simulated laboratory where they can mix substances and observe the reactions in real time. Before facing real situations, repair technicians can learn to disassemble and repair complex equipment in a virtual environment. In the educational field, the MR offers an advanced level of immersion and practical applications.
Artificial Intelligence (AI):
aids immersive training by enabling personalization and adaptation of educational content. AI systems can analyze and understand student data, find areas for improvement, and tailor the learning experience to individual needs. Realistic virtual characters with advanced interaction capabilities can also be created using artificial intelligence. These characters can play the role of virtual instructors, providing individualized feedback and guidance throughout the learning process. The creation of smarter and more efficient training systems is being driven by artificial intelligence.
