# Concept of Virtual Reality Training of Facility Management Employees Using Eye Tracking
## 6 Conclusions  
This article presents the concept of a VR environment for the training and evaluation of facility management staff using eye tracking, which allows for the reconstruction of identical test conditions for all participants, high comparability of training results, and advanced analysis of the results achieved by individual employees. Eye-tracking technology allows for an accurate analysis of the focus of each participant on the critical elements of the devices in the decision-making process, which enables obtaining a much more comprehensive range of information on the concentration and correctness of the employee's actions. The eye movement information allows us to assess better the learning process and the correctness of completing tasks within individual VR modules. The analysis of results achieved by training participants allowed them to be divided into two groups, which were defined as fast and slow learners. Achieving such an effect was possible thanks to the use of clustering of the results of each participant's skills tests conducted after completing training in all VR modules. The analysis of the results showed that the attractiveness of the tasks performed in VR modules impacts the result of participant training. In addition, among people included in the fast learner's cluster, there were relatively many people without experience working in the FM industry. The training results are mostly based on the constructed VR training environment quality and less on experience using similar devices. Recognizing an employee's ability to learn is essential to the employer, as it enables the identification of employees who require additional support. Thanks to the obtained information, it will be possible to predict how much training a given employee will need to master the knowledge within the industry specialization. This information will make it possible to propose a strategy for the professional development of this person within the examined competencies. Ultimately, the training should be fitted to the user and supported by a user-assistance system to help the participant learn effectively. The research results contribute to employee training in inspections of individual components of office and industrial buildings. Based on the research, a process innovation was developed as a cloud-based platform for the training and skill evaluation of facility management staff using a VR environment and eye-tracking technology: [[https://www.vrfmhub.com/en](https://www.vrfmhub.com/en)]([https://www.vrfmhub.com/en](https://www.vrfmhub.com/en)) (accessed on 2 May 2023). Using the VR environment technology, an employee can enter a simulated version of a building's technical infrastructure and receive practical training and verify skills in inspecting its tasks without exposing themselves to any danger or risking any damage to the technical infrastructure. The developed solution is intended for use by the facility management industry based on the SaaS (Software as a Service) sales model, in which the provider develops and maintains cloud applications, ensures their automatic updates, and makes the software available to its customers via the Internet on a \"pay-as-you-go\" basis, i.e., depending on the use of resources. Training in the VR environment with the use of eye-tracking technology, offered in the SaaS model with the possibility of purchasing the service online, has a good chance of achieving widespread use, as it will be an attractively priced opportunity to comfortably improve and verify employees' qualifications while reducing technical barriers to application. It is worth noting that it is possible to use achieved research results to build similar solutions for other industries. Future work will focus on developing a classifier that will automatically evaluate the results of the skills tests considering the results of eye movement. However, VR training with eye tracking provides a large amount of data describing the proceedings of the training process.
