By using innovative technologies such as augmented reality (AR), companies that offer field services are combating the shortage of skilled workers. One of the areas where AR makes a significant difference is the transfer of knowledge between professionals and the people on site. Let’s take electrical engineers as an example. In the field, they need to have their hands free to concentrate on the task at hand and to be able to access information easily and quickly. With the help of smart glasses and AR solutions, employees can immediately call a specialist without leaving the construction site and without having to use their hands.
